Musculoskeletal disorders ( MSDs ) affecting the back , upper and lower extremities are widespread in the general population , implying a variety of causal factors . Multiple causes are not mutually exclusive , and a high background rate does not preclude associations with specific factors that are uncommon in the general population . MSDs have well-documented associations with occupational ergonomic stressors such as repetitive motion , heavy lifting , non-neutral postures , and vibration . Organizational features of the work environment , such as time pressure and low decision latitude , may also play a role , at least by potentiating the effects of physical loading . Numerous systematic review s have mostly concurred with these overall findings . Nevertheless , some continue to debate whether MSDs are sometimes work-related , even for those performing jobs with repetitive and routinized tasks , heavy lifting , and /or pronounced postural strain . This article discusses ( 1 ) some epidemiologic features of MSDs that underlie that debate ; and ( 2 ) the question of what should appropriately be considered a gold st and ard for scientific evidence on an etiological question such as the health effects of a non-voluntary exposure , such as an occupational or environmental agent . In particular , r and omized clinical trials have little relevance for determining the health effects of non-therapeutic risk factors This article both summarizes the previous review s of r and omized , controlled trials of hypnotic analgesia for the treatment of chronic and acute pain in adults , and review s similar trials which have recently been published in the scientific literature . The results indicate that for both chronic and acute pain conditions : ( 1 ) hypnotic analgesia consistently results in greater decreases in a variety of pain outcomes compared to no treatment/st and ard care ; ( 2 ) hypnosis frequently out-performs non-hypnotic interventions ( e.g. education , supportive therapy ) in terms of reductions in pain-related outcomes ; and ( 3 ) hypnosis performs similarly to treatments that contain hypnotic elements ( such as progressive muscle relaxation ) , but is not surpassed in efficacy by these alternative treatments . Factors that may influence the efficacy of hypnotic analgesia interventions are discussed , including , but not limited to , the patient 's level of suggestibility , treatment outcome expectancy , and provider expertise . Based upon this body of literature , suggestions are offered for practitioners who are using , or would like to use , hypnosis for the amelioration of pain problems in their patients or clients STUDY DESIGN Systematic review and best evidence synthesis . OBJECTIVES To describe the prevalence and incidence of  neck pain and disability in workers ; to identify risk factors for neck pain in workers ; to propose an etiological diagram ; and to make recommendations for future research . SUMMARY OF BACKGROUND DATA Previous review s of the etiology of neck pain in workers relied on cross-sectional evidence . Recently published cohorts and r and omized trials warrant a re- analysis of this body of research . METHODS We systematic ally search ed Medline for literature published from 1980 - 2006 . Retrieved articles were review ed for relevance . Relevant articles were critically appraised . Articles judged to have adequate internal validity were included in our best evidence synthesis . RESULTS One hundred and nine papers on the burden and determinants of neck pain in workers were scientifically admissible . The annual prevalence of neck pain varied from 27.1 % in Norway to 47.8 % in Québec , Canada . Each year , between 11 % and 14.1 % of workers were limited in their activities because of neck pain . Risk factors associated with neck pain in workers include age , previous musculoskeletal pain , high quantitative job dem and s , low social support at work , job insecurity , low physical capacity , poor computer workstation design and work posture , sedentary work position , repetitive work and precision work . We found preliminary evidence that gender , occupation , headaches , emotional problems , smoking , poor job satisfaction , awkward work postures , poor physical work environment , and workers ' ethnicity may be associated with neck pain . There is evidence that interventions aim ed at modifying workstations and worker posture are not effective in reducing the incidence of neck pain in workers . CONCLUSION Neck disorders are a significant source of pain and activity limitations in workers . Most neck pain results from complex relationships between individual and workplace risk factors . No prevention strategies have been shown to reduce the incidence of neck pain in workers [ Purpose ] The purpose of this study was to identify the effect of purpose ful action observation on upper extremity function in patients with stroke . [ Subjects and Methods ] Twelve subjects were r and omly to either the experimental group or control group . The experimental group underwent occupational therapy and a purpose ful action observation program . The control group underwent occupational therapy and placebo treatment in which the subjects performed a purpose ful action observation program without actually observing the purpose ful actions . The Wolf Motor Function Test was used to measure upper extremity function before and after the intervention in both groups . [ Results ] Both the experimental and control groups demonstrated improved upper extremity function after the intervention , but there was no significant difference between groups . Compared with before the intervention , the experimental group showed significantly improved upper extremity function after the intervention . [ Conclusion ] Based on these results , a purpose ful action observation program can improve upper extremity function in patients with stroke . In future research , more subjects should be included for evaluation of different treatments OBJECTIVE To prospect ively monitor occupational therapy activities and intervention techniques used during inpatient stroke rehabilitation in order to provide a description of current clinical practice . METHODS Data were collected prospect ively from 954 clients with stroke receiving occupational therapy from six U.S. rehabilitation hospitals . Descriptive statistics summarized frequency , intensity , and duration of occupational therapy sessions ; proportion of time spent in 16 therapeutic activities ; and proportion of those activities that included any of 31 interventions . RESULTS Clients received on average 11.8 days ( SD = 7.2 ) of occupational therapy , with each session lasting on average 39.4 min ( SD = 16.9 ) . Upper-extremity control ( 22.9 % of treatment time ) and dressing ( 14.2 % of treatment time ) were the most frequently provided activities . Interventions provided most frequently during upper-extremity control activities were strengthening , motor learning , and postural awareness . CONCLUSION Occupational therapy provided reflected an integration of treatment approaches . Upper-extremity control and basic activities of daily living were the most frequent activities . A small proportion of sessions addressed community integration OBJECTIVE Since 2002 , an epidemiologic surveillance system of work-related , upper-limb musculoskeletal disorders ( MSDs ) has been implemented in France 's Pays de la Loire region to assess the prevalence of MSDs and their risk factors in the working population . METHODS The surveillance was based on a network of occupational physicians ( OPs ) and used the recommendations of a group of European experts ( criteria document consensus ) . In 2002 - 2003 , 80 of 400 OPs volunteered to participate . All underwent a training program to st and ardize the physical examination .  Health status was assessed by self-administered question naire and physical examination . Occupational risk factors were assessed by self-administered question naire .  Exposure scores were computed for each anatomic zone by summing the risk factors taken into account by the criteria document . RESULTS More than 50 % of the 2,685 men and women r and omly included in 2002 - 2003 experienced nonspecific musculoskeletal symptoms during the preceeding 12 months and approximately 30 % experienced them in the preceeding week . The prevalence of clinical ly diagnosed MSDs was high : approximately 13 % of workers experienced at least 1 of the MSDs . The most frequent disorder was rotator cuff syndrome followed by carpal tunnel syndrome and lateral epicondylitis . The prevalence of MSDs increased with age and varied widely across economic sectors and occupations . More than half of the workers were exposed to at least 2 risk factors of MSDs . Exposure varied according to industrial activity and occupation . According to the criteria document , a high percentage of MSD cases could be classified as probably work related ( 95 % in men and 89 % in women age < 50 , and 87 % in men and 69 % in women age > 50 ) . CONCLUSION Nonspecific upper-limb symptoms and specific upper-limb MSDs are common in the working population . These results show the need to implement prevention programs in most sectors to reduce the prevalence of MSDs Background Distal radius fractures are among the most common fractures and account for approximately one-sixth of all fractures diagnosed . Therapy results after distal radius fracture , especially of elderly patients , are often suboptimal . The inevitable immobilization for several weeks leads to reduction in range of motion , deterioration of muscle strength , malfunction of fine motor skills as well as changes of motor and sensory representations in the brain . Currently , there are no strategies to counteract these immobilization problems . The overall aim of the study is to investigate the therapeutic potential of motor-cognitive approaches ( mental practice or mirror therapy ) on h and function after wrist fracture . Methods / Design This study is a controlled , r and omized , longitudinal intervention study with three intervention groups . One experimental group imagines movements of the fractured upper extremity without executing them ( mental practice ) . The second experimental group receives a mirror therapy program consisting of the performance of functional movement synergies using the unaffected forearm , wrist , and h and . The control group completes a relaxation training regime . Additionally , all patients receive usual care by the general practitioner . We include women aged 60 years and older having a distal radius fracture and sufficient cognitive function . All groups are visited at home for therapy sessions 5 times per week for the first 3 weeks and 3 times per week for weeks 4 to 6 . Measurements are taken at therapy onset , and after 3 , 6 and 12 weeks . The primary outcome measure will assess upper extremity functioning ( Patient-Rated Wrist Evaluation [ PRWE ] ) , while secondary outcome measures cover subjective wrist function ( Disabilities of the Arm and Shoulder ; [ DASH ] , objective impairment ( range of motion , grip force ) and quality of life ( EuroQol-5D , [ EQ5D ] ) . Discussion Results from this trial will contribute to the evidence on motor-cognitive approaches in the early therapy of distal radius fractures . Trial registration The trial is registered at Clinical Trials.gov with registration number NCT01394809 and was granted permission by the Medical Ethical Review Committee of the University of Tübingen in June 2011 BACKGROUND Occupational health guidelines recommend a biopsychosocial approach to manage  sickness absence due to musculoskeletal disorders ( MSDs ) , with a primary focus on early intervention through provision of a supportive network . AIMS To investigate the implementation of a guidelines -based intervention ( early contact of absentees ; addressing psychosocial obstacles ; offering temporary modified work ; communicating among the players ) , and to determine whether this is effective for reducing return-to-work times and duration of future absence . METHODS A non-r and omized controlled trial was conducted within a UK company . Occupational health nurses at two experimental sites ( 1,435 workers ) were trained to deliver the intervention to workers taking absence due to MSDs ( low back and upper limb disorders ) , while usual care was delivered at three control sites ( 1,483 workers ) .  Company-recorded absence data were collected over a 12-month follow-up period . RESULTS The implementation of the experimental intervention was impeded by unforeseen organizational obstacles at one site ( policies , procedures and individual approaches ) which had a detrimental effect on uptake and delivery . At the site where the intervention was delivered per protocol , absence was significantly less compared with controls ; 6.5 and 10.8 days , respectively . However , the duration of future absence was not significantly different ( 13.0 and 25.1 days , respectively ) . CONCLUSIONS An early intervention addressing psychosocial obstacles to recovery can be effective for reducing absence due to MSDs . Successful implementation , where the key players are onside and organizational obstacles are overcome , is difficult to achieve This article describes an innovative preventive occupational therapy intervention for well older adults , the  Well Elderly Treatment Program . In a previously reported large-scale r and omized effectiveness study , this intervention was found to be highly successful in enhancing the physical and mental health , occupational functioning , and life satisfaction of multicultural , community-dwelling elders . In this article , the philosophical background , manner of development , topical content , methods of program delivery , and mechanisms underlying the program 's positive effects are discussed , along with implication s for occupational therapy practice . The treatment was based on application of occupational science theory and research and emphasized the therapeutic process of lifestyle re design in enabling the participants to actively and strategically select an individualized pattern of personally satisfying and health-promoting occupations . The wide-ranging effectiveness of the program supports the occupational therapy profession 's emphasis on occupation in affecting health and positions practitioners to extend their services to the realm of preventive interventions OBJECTIVES There is considerable evidence documenting the association between psychosocial risk factors and  work disability due to musculoskeletal disorders , and this has prompted suggestions that psychosocial screening should be administered in the workplace in order to identify individuals at risk of prolonged absence . However , the predictive value of psychosocial risk factors on return-to-work is largely unknown . The present study aim ed to explore the predictive relationship between psychosocial risk factors and absence due to musculoskeletal disorders of the lower back and upper limbs . METHODS A prospect i ve study of 4637 workers from a large , multi-site company in the UK was conducted in which a wide range of established question naires were used to collect baseline psychosocial data . Respondents were then followed over the ensuing 15 months , and absence due to musculoskeletal disorders was recorded . RESULTS 219 workers took absence due to musculoskeletal disorders . Detrimental cut-off scores ( risks ) on the psychosocial instruments were established , and it was found that work-related psychosocial risk factors predicted the likelihood of a future spell of absence ( odds ratios ranging between 1.6 and 3.2 ) , but not the duration of that absence . CONCLUSIONS Although work-related psychosocial factors were associated with the occurrence of absence due to musculoskeletal disorders , these findings do not lend support to the use of routine occupational psychosocial screening in order to predict prolonged absence Objective Less is known about nurse practitioners ' ( NPs ' ) effectiveness in acute care than about their effectiveness in outpatient setting s. This study investigated care activities and clinical outcomes for hospitalized geriatric patients treated by NPs compared with those treated by intern and resident physicians .  Data Sources A descriptive comparative research design involved r and om selection of 100 inpatient geriatric patients and a convenience sample of 17 professional providers who staffed three hospital units . A 1‐month study period produced retrospective and prospect i ve data for analysis . Self‐reports concerning 10 primary activity categories indicated that NPs spent a higher percentage of time doing  progress notes and care planning  than did physicians ( 28 % versus 15 % , p=.011 ) and that physicians spent more time on  literature review s ( 5 % versus 1 % , p=.008 ) . When prioritizing care activities , NPs ranked advance directive discussion higher than did physicians ( 2nd versus 7th , p=.036 ) , a difference confirmed by medical record documentation . Physicians were more attentive to functional status ( 1st versus 3rd , p=.023 ) , but medical record documentation showed NPs to be more attentive to physical and occupational therapy referrals ( p=.001 ) . Analysis of 13 independent organ areas revealed that NPs cared for more musculoskeletal ( p=.036 ) and psychiatric ( p=.005 ) problems . Physicians cared for more cardiac patients ( p=.001 ) . NPs ’ patients were older ( p=.022 ) and sicker at admission ( p < . 001 ) and discharge ( p < . 001 ) . Charges per length of stay were lower ( p < . 001 ) for the physician provider group , and patients in that group had shorter stays ( p < . 001 ) . Readmission and mortality rates were similar . Implication s for Practice NPs provide effective care to hospitalized geriatric patients , particularly to those who are older and sicker Objective : To determine the effectiveness and cost-effectiveness of a return-to-work outpatient multidisciplinary treatment programme for sick-listed workers with non-specific upper extremity musculoskeletal complaints . Methods : A r and omized controlled trial with a 1-year follow-up was carried out . Thirty-eight subjects were allocated to multidisciplinary treatment ( intervention , n=23 ) , or to usual care provided by occupational health services ( n=15 ) . The intervention consisted of psychological and physical sessions provided by a medical specialist , a psychologist , a physiotherapist and an occupational therapist . It aims at reconditioning , “ de-medicalizing ” , unrestrained moving and return-to-work . The intervention process was evaluated on compliance to the protocol and the effectiveness of its components . The individual outcome variable was the severity of complaints . The societal outcomes included return-to-work and costs . Measurements were performed at baseline and after 2 , 6 and 12 months . Mixed model analyses were used for analysis . Results : The intervention achieves its aims : physical disabilities ( P=0.039 ) , kinesiophobia ( P<0.001 ) and physical functioning ( P=0.016 ) improved significantly as compared to usual care . In addition , the intervention was significantly more effective in reducing the severity of complaints than usual care . The intervention was equally effective compared to usual care in terms of return-to-work ( 86 % in the intervention group vs. 73 % in the usual care group ) . The extra total costs and the extra gains in terms of return-to-work were not significantly higher for the intervention as compared to usual care after 12 months . Conclusion : Multidisciplinary treatment affects individuals positively , but shows no significant difference in ( cost- ) effectiveness on the societal level as compared to usual care The purpose of this paper is to review the evidence estimating an impact of occupational factors on  mood disorders and suicide  , and the efficacy of interventions . This review is based on literature search es using Medline and Psych INFO from 1966 to 2007 ( keywords : work stress , job insecurity , job strain , shift work , violence , occupational health , mood disorders , depression , and suicide ) . To establish the relationship between occupational variables and mood disorders , we focused on clinical ly significant disorders rather than depressive symptoms . During the last decade , prospect i ve epidemiological studies have suggested a predictive association between the work environment and mood disorders . Recently , increasing numbers of clinical trials have shown favorable effect size of intervention and suggested preferable return-on-investment results . However , low awareness and social stigma still decrease workers access to treatment . Mental health professionals in conjunction with employers have to devise a creative system to make the quality care being offered more accessible to employees . In addition , further outcome data is needed to evaluate the benefit of managing mood disorders in the workplace , and to foster awareness of positive implication s for employees , employers , their families , and the society at large . In addition , the work environment , with its chemical ( e.g. chemosensory factors , pollutants ) , physical ( e.g. lighting , noise , temperature , outdoor views and activities ) , biological ( e.g. , chronobiological factors , allergens , infectious agents ) , psychological ( e.g. dem and -control , effort-reward balance ) , social ( e.g. cohesiveness , support ) , and organizational ( e.g. leadership styles ) component should meet minimal st and ards , and may improve with striving towards the optimum Patients hope that their doctors will correctly identify health problems , clearly articulate sensible options for managing each problem , wisely interpret the best available evidence about probable outcomes associated with each option , sensitively solicit patient preferences for each outcome , and thereby implement practice s that are likely to achieve the results patients care about . Groups of patients hope that doctors will work to prevent , detect , and treat health problems in a way that maximizes the public good achieved with available health care re sources . To meet these dual expectations , doctors face forbidding tasks of clinical decision making . Improved methods for preparing , appraising , and abstract ing overviews of available evidence about a clinical topic can bring a broader range of high- quality information within the busy practitioner 's grasp [ 1 - 4 ] . However , even well- design ed overviews often do not synthesize information about benefits , harms , and costs of medical practice s in a way that facilitates clinical decision making . Clinical practice guidelines have been defined as systematic ally developed statements to assist practitioner and patient decisions about appropriate health care for specific clinical circumstances [ 5 ] . Guidelines that are based on sound scientific evidence , and a trustworthy process for judging the value of alternative practice s , could help physicians deal with the information overload they face . Existing practice guidelines , however , vary widely in their quality , and clinicians should carefully consider the validity and applicability of each guideline they read . We propose a structured format for abstract s of articles describing practice guidelines that is based on emerging principles of guideline development and evaluation [ 6 - 13 ] . The proposal is design ed to help readers obtain the key information needed to assess the applicability , importance , and validity of any guideline . The proposed structure for more informative abstract s of articles describing clinical practice guidelines has been review ed and pilot-tested by guideline developers , evaluators , and implementors and by groups of practicing clinicians . Early versions of the proposal were sent to consultants at the National Library of Medicine , the Institute of Medicine , the American College of Physicians ( ACP ) , and the Agency for Health Care Policy and Research . Subsequent versions of the proposal were pilot tested on various published guidelines and were assessed by selected health care organizations for applicability to guidelines under development . An improved proposal was sent to 82 persons active in guideline development , evaluation , and implementation . The Internal Medicine Center to Advance Research and Education circulated the proposal to volunteer practitioners , and the authors solicited feedback from physician and health administrator participants at three national workshops about practice guidelines . The proposal that follows represents an integration of the collective wisdom of our external review ers . ( A glossary of terms used in articles on clinical practice guidelines is supplied in the Appendix . ) Proposed Structure and Content for Abstract s of Articles Describing Clinical Practice Guidelines The proposed structure for abstract s of papers describing clinical practice guidelines is summarized in Table 1 . Key elements of the guideline development process are captured with statements about the principal objective and target of the guideline , the main practice options and outcomes that were considered , the nature of the evidence and values that were analyzed , the main benefits and harms expected from guideline implementation , the key recommendations , and a statement of whether the recommendations have been tested and by whom they have been endorsed . If details about guideline development methods or supporting evidence are published separately , then the abstract should indicate the existence of supporting documents and the most relevant parts of those should be summarized in the abstract . To be included in their entirety in the online bibliographic data bases of the National Library of Medicine , structured abstract s of clinical practice guidelines should not exceed 4096 characters ( approximately 500 words ) in length . Individual journals may have different requirements . Table 1 . Proposed Format for Structured Abstract s of Clinical Practice Guidelines Objective The abstract should state the objective of the guideline by identifying the targeted health problem , the targeted patients and physicians , and the main reason or reasons for developing new recommendations concerning this problem for this population . For guidelines primarily concerned with the management of health conditions , the stage of illness and intent to prevent , diagnose , treat , or palliate the disorder should be specified . For guidelines primarily concerned with health procedures , an intervention and its role in patient management should be defined . Targeted providers , setting s , and patients should be specified so that readers can tell who should do what , where it should be done , and to whom . A statement of objective also may specify why a new guideline is needed and how it should be used . Practice guidelines may be written to clarify or resolve clinical controversies , to communicate important new findings from clinical studies , or to promote more effective , efficient , or consistent physician practice s at less cost or risk to patients . Guidelines may be used concurrently to help physicians and patients make choices ( for example , clinical algorithms ) , retrospectively to compare physician choices to pre-established criteria ( for example , utilization review ) , or prospect ively to set limits on physician choices ( for example , preprocedure approval ) . Options Clinical practice guidelines pertain to clinical decisions . The nature of those decisions should be made explicit by disclosing the main management options considered . The abstract should list principal alternative preventive , diagnostic , or therapeutic strategies available to targeted clinicians and patients . Outcomes The abstract also should specify which health outcomes , such as death , morbidity , quality of life , economic costs , or changes in the process of health care were considered . Evidence To estimate the probable effect of a health intervention on an outcome , relevant data must be defined , gathered , and appraised . Readers need to know what kind of evidence was considered and what methods were used to select and combine evidence from different sources . Potential sources of evidence about clinical outcomes include the results of clinical studies ( published or unpublished ) , expert opinion , information contained in public or private health data bases , and direct input from patients or providers . Potential sources of evidence about economic outcomes include the results of cost-effectiveness studies , various fee schedules , and information contained in public or private health cl aims data bases . Potential methods of gathering evidence include computerized search es for articles that satisfy predetermined criteria , review s of bibliographies of relevant articles , and surveys of relevant persons or organizations [ 1 ] . The abstract should state whether explicit methods were used to combine results from scientific studies ( for example , meta- analysis ) or opinions of experts ( for example , Delphi technique ) [ 14 , 15 ] . The abstract may also indicate whether specific criteria were used to gauge the quality of information from different sources [ 16 , 17 ] . Scientific evidence regarding the likelihood of certain outcomes is often missing or conflicting . It is desirable for the strength of evidence supporting a guideline to be gauged in some way [ 16 ] . If gaps in the evidence were bridged formally ( for example , through use of decision- analysis models ) or informally ( for example , best guess of clinical experts ) , then major assumptions or areas of uncertainty should be acknowledged [ 11 ] . Because of the extraordinary time required to properly assemble and review evidence and then to achieve consensus about practice recommendations , the abstract of a practice guideline should specify the publication date s of the most recent evidence considered . If a sensitivity analysis was performed , then any major vulnerability of the guideline to weaknesses in the evidence should be acknowledged . These considerations may be summarized by qualifying a guideline as provisional by specifying date s for expiration or review , by listing studies in progress that could affect the guideline , or by identifying key research priorities . Values The declaration of a recommended practice presumes an implicit or explicit process for judging the relative desirability of the health , economic , and process outcomes associated with alternative practice s. These are matters of opinion and value . For example , in developing guidelines for breast cancer screening , it is necessary to weigh the value of preventing a death from breast cancer against the value of avoiding unnecessary harm or anxiety in women who do not have breast cancer . A high value placed on maximizing detection of asymptomatic malignancy may motivate an organization to recommend teaching self-examination of breasts to young women [ 18 ] . A relatively greater value placed on avoiding false-positive results may motivate others to not promote such programs [ 19 ] . Consequently , the principal sources of such values and the method by which judgments were made should be reported in guideline abstract s. At a minimum , the abstract should identify the major groups that participated in the process of assigning values to outcomes ( for example , generalist or specialist physicians , other health care providers , insurers , representatives of health organizations , and special-interest groups ) and whether patient preferences were represented . The abstract may also indicate the method used to synthesize opinions from Objectives : The aim of this intervention study was to determine the effects of an alternative mouse and /or a forearm support board on the change in upper body discomfort scores and the development of incident musculoskeletal disorders . Methods : This r and omised controlled intervention trial followed 206 engineers for one year . Participants were r and omised to receive ( 1 ) a conventional mouse only , ( 2 ) an alternative mouse only , ( 3 ) a forearm support board , or ( 4 ) an alternative mouse plus forearm support board . Outcome measures included weekly upper body discomfort scores and incident musculoskeletal disorders . Results : During the study , 42 participants were diagnosed with an incident musculoskeletal disorder . The group that received the forearm support board experienced a reduction in their right upper extremity discomfort ( beta-coefficient −0.35 , 95 % CI −0.67 to −0.03 ) in comparison to those who did not receive a forearm board . The group that received the alternative mouse had a protective , but non-significant ( p = 0.20 ) , effect on incident cases of right upper extremity musculoskeletal disorders ( HR 0.57 , 95 % CI 0.24 to 1.34 ) and a non-significant reduction in neck/shoulder discomfort ( beta-coefficient −0.23 , 95 % CI −0.056 to 0.10 ) in comparison to those who received a conventional mouse . Conclusions : In engineers who use a computer for more than 20 h per week , a forearm support board may reduce right upper extremity discomfort attributed to computer use Background Major depressive disorder ( MDD ) has major consequences for both patients and society , particularly in terms of needlessly long sick leave and reduced functioning . Although evidence -based treatments for MDD are available , they show disappointing results when implemented in daily practice . A focus on work is also lacking in the treatment of depressive disorder as well as communication of general practitioners ( GPs ) and other health care professionals with occupational physicians ( OPs ) . The OP may play a more important role in the recovery of patients with MDD . Purpose of the present study is to tackle these obstacles by applying a collaborative care model , which has proven to be effective in the USA , with a focus on return to work ( RTW ) . From a societal perspective , the (cost)effectiveness of this collaborative care treatment , as a way of transmural care , will be evaluated in depressed patients on sick leave in the occupational health setting . Methods / Design A r and omised controlled trial in which the treatment of MDD in the occupational health setting will be evaluated in the Netherl and s. A transmural collaborative care model , including Problem Solving Treatment ( PST ) , a workplace intervention , antidepressant medication and manual guided self-help will be compared with care as usual ( CAU ) .  126 Patients with MDD on sick leave between 4 and 12 weeks will be included in the study .  Care in the intervention group will be provided by a multidisciplinary team of a trained OP-care manager and a consultant psychiatrist . The treatment is separated from the sickness certification . Data will be collected by means of question naires at baseline and at 3 , 6 , 9 and 12 months after baseline . Primary outcome measure is reduction of depressive symptoms , secondary outcome measure is time to RTW , tertiary outcome measure is the cost effectiveness . Discussion The high burden of MDD and the high level of sickness absence among people with MDD contribute to the relevance of this study . The intervention is an innovative approach , with trained OPs in a new role as care managers in the treatment of MDD . If this intervention proves to be cost-effective , implementation will be very relevant for individual patients as well as for society . Trial registration IS RCT BACKGROUND The effect of formal occupational therapy on recovery after open reduction and volar plate fixation of a fracture of the distal part of the radius is uncertain . We hypothesized that there would be no difference in wrist function and arm-specific disability six months after open reduction and volar plate fixation of a distal radial fracture between patients who receive formal occupational therapy and those with instructions for independent exercises .  METHODS Ninety-four patients with an unstable distal radial fracture treated with open reduction and volar locking plate fixation were enrolled in a prospect i ve r and omized controlled trial comparing exercises done under the supervision of an occupational therapist with surgeon-directed independent exercises . The primary study question addressed combined wrist flexion and extension six months after surgery Secondary study questions addressed wrist motion , grip strength , Gartl and and Werley scores , Mayo wrist scores , and DASH ( Disabilities of the Arm , Shoulder and H and ) scores at three months and six months after surgery . RESULTS There was a significant difference in the mean arc of wrist flexion and extension six months after surgery ( 118 ° versus 129 ° ) , favoring patients prescribed independent exercises . Three months after surgery , there was a significant difference in mean pinch strength ( 80 % versus 90 % ) , mean grip strength ( 66 % versus 81 % ) , and mean Gartl and and Werley scores , favoring patients prescribed independent exercises . At six months , there was a significant difference in mean wrist extension ( 55 ° versus 62 ° ) , ulnar deviation ( 82 % versus 93 % ) , mean supination ( 84 ° versus 90 ° ) , mean grip strength ( 81 % versus 92 % ) , and mean Mayo score , favoring patients prescribed independent exercises . There were no differences in arm-specific disability ( DASH score ) at any time point . CONCLUSIONS Prescription of formal occupational therapy does not improve the average motion or disability score after volar locking plate fixation of a fracture of the distal part of the radius OBJECTIVE This executive summary presents in brief the current evidence assessed in the clinical practice guideline prepared by the Canadian Hypertensive Disorders of Pregnancy Working Group and published by Pregnancy Hypertension ( http://www.pregnancyhypertension.org/article/S2210-7789(14)00004-X/fulltext ) to provide a reasonable approach to the diagnosis , evaluation , and treatment of the hypertensive disorders of pregnancy . EVIDENCE Published literature was retrieved through search es of Medline , CINAHL , and The Cochrane Library in March 2012 using appropriate controlled vocabulary ( e.g. , pregnancy , hypertension , pre-eclampsia , pregnancy toxemias ) and key words ( e.g. , diagnosis , evaluation , classification , prediction , prevention , prognosis , treatment , postpartum follow-up ) . Results were restricted to systematic review s , r and omized control trials , controlled clinical trials , and observational studies published in French or English between January 2006 and February 2012 . Search es were up date d on a regular basis and incorporated in the guideline to September 2013 . Grey ( unpublished ) literature was identified through search ing the websites of health technology assessment and health technology-related agencies , clinical practice guideline collection s , clinical trial registries , and national and international medical specialty societies . VALUES The quality of evidence in the guideline summarized here was rated using the criteria described in the Report of the Canadian Task Force on Preventative Health Care ( Table 1 ) At the end of a long week in the office , you sink back into your chair , reflecting on some of the more memorable patients you cared for and counseled . Through gentle history taking , you discovered that urinary incontinence is the underlying cause of an elderly patient 's increasing social isolation . During a careful physical examination , you detected bruising on the torso of a woman with chronic headaches and began to explore the longst and ing abusive relationship between the woman and her alcoholic partner . You discontinued procainamide therapy in a 72-year-old man who had asymptomatic premature ventricular contractions after myocardial infa rct ion . To prevent bleeding from esophageal varices , you started -blocker therapy in a woman with long-st and ing cryptogenic cirrhosis and portal hypertension . In couples ' therapy , discussing the future quality of life of a middle-aged gay man with human immunodeficiency virus infection , you journeyed through emotionally intense dialogue about advance directives . You presented the risk factors for major and minor bleeding to a 39-year-old woman who was considering warfarin therapy because of recently diagnosed atrial fibrillation and valvular heart disease . You listened to , made diagnoses for , treated , advised , and comforted many patients . Yet there were some hiccoughs in your practice along the way . You stumbled while debating the pros and cons of breast cancer screening with a healthy 48-year-old woman who has been staying current with information on the Internet . You question ed the merits of a personalized walking program suggested to you by a motivated 66-year-old man with severe claudication . Explaining that you wanted to review the best current evidence on these issues , you resolved to address your uncertainties before these patients made their next office visits , in a week 's time . Sighing deeply , you acknowledge that you have little time to read . You subscribe to three journals , which you browse months after they arrive-either when your journal stack becomes precariously high or when your guilt is sufficiently motivational . You sometimes find the conclusions of individual articles conflicting or confusing . You know that some of the decisions and suggestions you made this week , specifically your decisions about stopping procainamide therapy and starting -blocker therapy and your advice about bleeding risks from anticoagulant therapy , were based on the best current research evidence [ 1 - 3 ] . On the other h and , your patients ' inquiries about breast cancer screening and exercise treatment for claudication highlight your need for a concise , current , rigorous synthesis of the best available evidence on each of these topics : in brief , a systematic review [ 4 , 5 ] . Incorporating Research Evidence into Clinical Decision Making The foregoing scenario is familiar to practitioners . In a typical week , we encounter patients with diverse problems ; exercise numerous clinical , interpersonal , and technical skills ; and make many decisions . The factors that affect these decisions and their outcomes are complex . For instance , each patient has unique sociodemographic characteristics , cultural circumstances , and personal preferences . Each physician has unique knowledge , experiences , and values . Moreover , practitioners and their patients make decisions within the context of a rapidly changing health care system that influences the availability , accessibility , and cost of diagnostic tests and therapies [ 6 ] . Timely , useful evidence from the biomedical literature should be an integral component of clinical decision making . If one treatment has been shown to be better than another , we need to know , so that we can recommend the treatment to the appropriate patients . The worldwide effort to develop new tests and treatments , and to determine their usefulness , has never been stronger , and our patients and their families expect us to be fonts of the knowledge that results from this effort [ 7 ] . Unfortunately , it is easy for current best research evidence to pass us by [ 8 ] . We may lack the time , motivation , and basic skills needed to find , critically appraise , and synthesize information , all of which we must do if we are to integrate the results of original studies into our practice . Fortunately , several potent methods are emerging that can greatly enhance our ability to interpret and apply research evidence ; foremost among them is the systematic review . This article begins a series in Annals that will examine systematic review s in detail and explore their many applications . Systematic review s represent the best chance that most practitioners will have to underst and and accurately apply the key signals arising from the robust and increasingly productive search for solutions to medical problems . A properly conducted systematic review faithfully summarizes the evidence from all relevant studies on the topic of interest , and it does so concisely and transparently . What Is a Systematic Review ? Systematic review s are scientific investigations in themselves , with pre-planned methods and an assembly of original studies as their subjects . They synthesize the results of multiple primary investigations by using strategies that limit bias and r and om error [ 9 , 10 ] . These strategies include a comprehensive search of all potentially relevant articles and the use of explicit , reproducible criteria in the selection of articles for review . Primary research design s and study characteristics are appraised , data are synthesized , and results are interpreted . When the results of primary studies are summarized but not statistically combined , the review may be called a qualitative systematic review . A quantitative systematic review , or meta- analysis , is a systematic review that uses statistical methods to combine the results of two or more studies . The term overview is sometimes used to denote a systematic review , whether quantitative or qualitative . Summaries of research that lack explicit descriptions of systematic methods are often called narrative review s. Review articles are one type of integrative publication ; practice guidelines , economic evaluations , and clinical decision analyses are others . These other types of integrative articles often incorporate the results of systematic review s. For example , practice guidelines are systematic ally developed statements intended to assist practitioners and patients with decisions about appropriate health care for specific clinical circumstances [ 11 ] . Evidence -based practice guidelines are based on systematic review s of the literature , appropriately adapted to local circumstances and values . Economic evaluations compare both the costs and the consequences of different courses of action ; the knowledge of consequences that are considered in these evaluations is often generated by systematic review s of primary studies . Decision analyses quantify both the likelihood and the valuation of the expected outcomes associated with competing alternatives . Differences between Systematic and Narrative Review s All review s , narrative and systematic alike , are retrospective , observational research studies and are therefore subject to systematic and r and om error . Accordingly , the quality of a review - and thus its worth-depends on the extent to which scientific review methods have been used to minimize error and bias . This is the key feature that distinguishes traditional narrative review s from systematic review s ( Table 1 ) . If a review is prepared according to the steps outlined in the right column of Table 1 , it is more likely to be systematic and to provide unbiased conclusions . If review methods approximate those found in the middle column of Table 1 , the article is more likely to be a narrative review , and the conclusions are less likely to be based on an unbiased summary of all relevant evidence . Table 1 . Differences between Narrative Review s and Systematic Review s Systematic review s are generated to answer specific , often narrow , clinical questions in depth . These questions can be formulated explicitly according to four variables : a specific population and setting ( such as elderly out patients ) , the condition of interest ( for example , hypertension ) , an exposure to a test or treatment ( such as pharmacologic management ) , and one or more specific outcomes ( such as cardiovascular and cerebrovascular events and mortality ) [ 12 ] . Thus , an example of a well-formulated , clinical ly relevant question is , Does pharmacologic treatment of hypertension in the elderly prevent strokes and myocardial infa rct ions or delay death ? If the question that is driving the review is not clear from the title , abstract , or introduction , or if no methods section is included , the paper is more likely to be a narrative review than a systematic review [ 13 ] . Most narrative review articles deal with a broad range of issues related to a given topic rather than addressing a particular issue in depth [ 9 ] . For example , a narrative review on diabetes ( such as that which might be found in a textbook chapter ) might include sections on the physiology and pathophysiology of carbohydrate , lipid , and protein metabolism ; the epidemiology of and prognosis associated with diabetes ; diagnostic and screening approaches ; and preventive , therapeutic , rehabilitative , and palliative interventions . Thus , narrative review s may be most useful for obtaining a broad perspective on a topic ; they are less often useful in furnishing quantitative answers to specific clinical questions . Narrative review s are appropriate for describing the history or development of a problem and its management . Narrative review s may better describe cutting-edge developments if research is scant or preliminary or if studies are very limited by flawed design or execution [ 13 ] . They may be particularly useful for discussing data in light of underlying theory and context . Narrative review s can draw analogies and can conceptually integrate two independent fields of research , such as This article considers the evidence for effectiveness and timing of rehabilitation  for people with rheumatoid arthritis ( RA ) . The Cochrane Library , DARE , Medline , Embase , CINAHL and AMED were search ed to identify systematic review s and r and omized controlled trials evaluating rehabilitation interventions for people with rheumatoid arthritis . Many trials identified had method ological limitations ( e.g. short follow-up periods , small sample sizes ) . Evidence to date is that symptomatic relief results from thermotherapy , laser therapy , acupuncture and assistive devices . In the short-term , comprehensive occupational therapy ( in established rheumatoid arthritis ) , orthoses , and mind-body approaches can help maintain function . Over at least a one-year period , the following are effective in reducing pain and maintaining function :  patient education and joint protection training using behavioural approaches ; dynamic exercise therapy , h and exercises and hydrotherapy ; and cognitive-behavioural therapy ( in people with poorer psychological status ) . Many trials have recruited people with moderate to severe , established RA and relatively little is known about the long-term effectiveness of early rehabilitation , although this is becoming much more common in practice . Despite the increased availability of guidelines and systematic review s , most conclude there is insufficient evidence for many areas of rheumatology rehabilitation . Further well- design ed clinical trials are needed recruiting people with early disease using patient-centred outcomes OBJECTIVES A cross-sectional study was conducted to assess the association of upper extremity musculoskeletal disorders and work-related factors among employees using video display terminals at a large metropolitan newspaper . METHODS The study included 1050 r and omly selected workers from four departments . The workers were asked to complete question naires on symptoms , job tasks , and psychosocial and work organization conditions . Musculoskeletal disorders of the upper extremities were defined by frequency , duration , and intensity of symptoms not attributable to acute injury . Data were analyzed with the use of logistic regression . RESULTS A total of 973 workers completed the survey . The one-year period prevalence rate for any musculoskeletal disorder of the upper extremities was 41 % . Neck symptoms ( 26 % ) were the most frequently reported , followed by h and or wrist ( 22 % ) , shoulder ( 17 % ) , and elbow ( 10 % ) symptoms . Greater time working at the video display station was associated with increased h and or wrist symptoms in a dose-response relationship . In addition , variables corresponding to increased work-load dem and s ( eg , increased time working under deadline and increased job pressure ) were associated with increased neck , shoulder , and h and or wrist disorders . Women were more likely to report symptoms in several areas , but this finding may reflect the concentration of women in jobs involving more risk factors . CONCLUSIONS The results suggest a high prevalence of musculoskeletal disorders of the upper extremities among newspaper employees , and they provide additional evidence that increased work load , time pressure , and greater hours of computer use are related to the occurrence of work-related musculoskeletal disorders among these workers , particularly for disorders in the h and or wrist area UNLABELLED Purpose : To perform a systematic review with best evidence synthesis examining the literature on the relationship between occupational loading tasks and  knee osteoarthritis ( OA ) . METHODS Two data bases were search ed to identify articles published between 1946 and April , 2011 . Eligible studies were those that ( 1 ) included adults reporting on their employment history ; ( 2 ) measured individuals ' exposure to work-related activities with heavy loading in the knee joint ; and ( 3 ) identified presence of knee OA ( determined by X-ray ) , cartilage defects associated with knee OA ( identified by magnetic resonance imaging ) , or joint replacement surgery . RESULTS A total of 32 articles from 31 studies met the inclusion criteria . We found moderate evidence that combined heavy lifting and kneeling is a risk factor for knee OA , with odds ratios ( OR ) varying from 1.8 to 7.9 , and limited evidence for heavy lifting ( OR=1.4 - 7.3 ) , kneeling ( OR=1.5 - 6.9 ) , stair climbing ( OR=1.6 - 5.1 ) , and occupational groups ( OR=1.4 - 4.7 ) as risk factors . When examined by sex , moderate level evidence of knee OA was found in men ; however , the evidence in women was limited . CONCLUSIONS Further high- quality prospect i ve studies are warranted to provide further evidence on the role of occupational loading tasks in knee OA , particularly in women Musculoskeletal injuries are a common presentation to the ED , with significant costs involved in the management of these injuries , variances in care within the ED and associated morbidity . A series of rapid review papers were completed to guide best practice for the assessment and management of common musculoskeletal injuries presenting to the ED . This paper presents the methodology used across the rapid review s. PubMed , CINAHL , EMBASE , TRIP and the grey literature , including relevant organisational websites , were search ed in 2015 . The search was repeated consistently for each topic area ( injuries of the foot and ankle , knee , h and and wrist , elbow , shoulder , lumbar spine and cervical spine ) . English- language primary studies , systematic review s and guidelines that were published in the last 10 years and addressed acute musculoskeletal injury management were considered for inclusion . Data extraction of each included article was conducted , followed by a quality appraisal . The extracted data from each article was synthesis ed to group similar evidence together . For each rapid review , the evidence has been organised in a way that a clinician can direct their attention to a specific component of the clinical cycle of care in the ED , such as the assessment , diagnostic tests , management and follow-up considerations from ED . The series of rapid review s are design ed to foster evidence -based practice within the ED , targeting the injuries most commonly presenting . The review s provide clinicians in EDs with rapid access to the best current evidence , which has been synthesis ed and organised to assist decision-making
The strongest evidence supports postsurgical early active motion protocol s and splinting for various conditions .
Very few studies have examined occupation-based interventions .
Occupational therapy practitioners are key health care providers for people with musculoskeletal disorders of the distal upper extremity .
It is imperative that practitioners underst and the most effective and efficient means for remediating impairments and supporting clients in progressing to independence in purpose ful occupations .
This systematic review provides an up date to a previous review by summarizing articles published between 2006 and July 2014 related to the focused question , What is the evidence for the effect of occupational therapy interventions on functional outcomes for adults with musculoskeletal disorders of the forearm , wrist , and h and ?
