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 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 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 Typing is associated with musculoskeletal disorders ( MSDs ) caused by multiple risk factors . This control study aim ed to evaluate the efficacy of a workplace intervention for reducing  MSDs among computer workers . Sixty-six subjects with and without MSD were assigned consecutively to one of three groups : ergonomics intervention ( work site and body posture adjustments , muscle activity training and exercises ) accompanied with biofeedback training , the same ergonomics intervention without biofeedback and a control group . Evaluation of MSDs , body posture , psychosocial status , upper extremity ( UE ) kinematics and muscle surface electromyography were carried out before and after the intervention in the workplace and the motion lab . Our main hypothesis that significant differences in the reduction of MSDs will exist between subjects in the study groups and controls was confirmed ( χ2 = 13.3 ; p = 0.001 ) . Significant changes were found in UE kinematics and posture as well . Both ergonomics interventions effectively reduced MSD and improved body posture . Practitioner Summary : This study aim ed to test the efficacy of an individual workplace intervention programme among computer workers by evaluating musculoskeletal disorders ( MSDs ) , body posture , upper extremity kinematics , muscle activity and psychosocial factors were tested . The proposed ergonomics interventions effectively reduced MSDs and improved body posture 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 Study Design . A prospect i ve cohort . Objectives . To compare the effectiveness of st and ard care , early intervention treatment , and occupational management in the management of Workers ’ Compensation injury cl aims . Summary of Background Data . The current management of occupational back pain and work-related upper extremity disorders with either st and ard care or early intervention treatment appears to be ineffective . Methods . A prospect i ve cohort looked at the effect of one company with access to st and ard care ( primary care ) changing to occupational management ( worksite encouragement to resume activity and work as soon as safely possible ) and then to early intervention treatment ( offsite work hardening ) . This information was then compared with the control company with access to early intervention treatment , which later changed to a combined occupational management/early intervention treatment approach .  Survival analysis was used to attempt to explain differences in time to injury cl aim closure . Results . Occupational management result ed in lower injury cl aim incidence , duration , and costs than early intervention treatment . Only the covariate of enhanced physical therapist ( work hardening ) involvement ( 2001 hazard rate ratio 17.41 , 95 % confidence interval 3.72–41.51 and 2002 hazard rate ratio 6.22 , 95 % confidence interval 2.51–15.40 ) was associated with delayed time to injury cl aim closure when the company had access to early intervention treatment . Only the covariate of serious injury was associated with delayed time to injury cl aim closure in the company when it had access to occupational management ( hazard rate ratio 1.67 , 95 % confidence interval 1.05–27.20 ) . Conclusions . It is recommended that an occupational management approach , in comparison to early intervention treatment and st and ard care , be considered for management of occupational injuries BACKGROUND AND OBJECTIVES Upper extremity musculoskeletal disorders ( MSD ) are very common in regular computer users and leading cause of work related illness . The objective of the present study is to evaluate effectiveness of yogic exercises in the improvement of symptoms of MSDs of upper limbs . MATERIAL S AND METHODS 60 study participants were r and omly divided into two groups that is yoga with counselling and only counselling group for 12 weeks . Symptom severity and functional status were assessed using the self administered Boston Carpal Tunnel Question naire and pre design ed symptom question naire before and after intervention . RESULTS There was significant reduction in symptom severity score ( P = 0.002 ) and improvement in functional status score in yoga with counselling group when compared to only counselling group . There is also a significant decrease in self reported symptoms like CT myalgia symptom ( P = 0.019 ) and improvement in weakness . CONCLUSION The present study showed a yoga based regimen is more effective than counselling alone in relieving symptoms of computer related musculoskeletal disorders Study Design . A retrospective and prospect i ve cohort . Objectives . To compare the effectiveness of occupational intervention , early intervention , and st and ard care in the management of Worker ’s Compensation injury cl aims . Summary of Background Data . The current management of occupational back pain and work-related upper extremity disorders with either st and ard care or early intervention appears to be ineffective . Methods . A retrospective cohort compared injury cl aim incidence , duration ,  and costs  between one company with access to st and ard care and another similar company with access to early intervention .  A prospect i ve cohort looked at the effect of one company changing from  st and ard care to occupational management  in comparison with the control group with early intervention .  Survival analysis was used to attempt to explain differences in injury cl aim duration . Results . St and ard care result ed in lower injury cl aim incidence , duration , and costs than early intervention , whereas occupational management result ed in lower injury cl aim incidence , duration , and costs than st and ard care . The covariates of physical therapist involvement , chiropractor involvement , injury severity , and relationship between Worker ’s Compensation and the employer were associated with delayed time to cl aim closure in the company with access to early intervention with the most important covariate being physical therapist involvement ( hazard rate ratio 19.88 , 95 % confidence interval 7.95–39.77 ) . Only the covariate of injury severity was associated with delayed time to cl aim closure in the company with access to occupational management ( hazard rate ratio 1.67 , 95 % confidence interval 1.05–27.20 ) . Conclusions . It is recommended that an occupational management approach , in comparison with st and ard care or early intervention , be considered for management of occupational injuries OBJECTIVES The aim of this study was to assess the effect of an ergonomic intervention on pain and sickness absence caused by upper-extremity musculoskeletal disorders . METHODS In this r and omized controlled study , subjects aged 18 - 60 years ( N=177 ) seeking medical advice due to upper-extremity symptoms were included if their symptoms , or the exacerbation of symptoms , had started < 30 days prior to the medical consultation and immediate sick leave was not required .  Workplace ergonomic improvements were made in the intervention group . Data on symptoms and sickness absences were gathered during one-year follow-up . RESULTS Pain intensity , pain interference with work , leisure time , or sleep did not differ between the intervention and control group during the one-year follow-up . During the first three months of follow-up , the percentage of employees with sickness absence due to upper-extremity or other musculoskeletal disorders did not differ between the intervention ( N=89 ) and control ( N=84 ) group , but the total number of sickness absence days in the intervention group was about half of that in the control group ( mean 6.2 versus 9.8 days for upper-extremity disorder and 6.0 versus 11.5 days for upper-extremity and other musculoskeletal disorders combined ) . During 4 - 12 months of follow-up , the percentage of employees with sickness absence due to upper-extremity disorder ( 10.1 % versus 16.7 % , P=0.20 ) or upper-extremity and other musculoskeletal disorders combined ( 20.2 % versus 32.1 % , P=0.07 ) was lower in the intervention than the control group . CONCLUSIONS Our findings suggest that an early ergonomic intervention reduces sickness absence due to upper-extremity or other musculoskeletal disorders Abstract Purpose We conducted a systematic review to critically appraise and synthesize literature on the effectiveness of work disability prevention ( WDP ) interventions in workers with neck pain , whiplash-associated disorders ( WAD ) , or upper extremity disorders . Methods We search ed electronic data bases from 1990 to 2012 . R and om pairs of independent review ers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria . Scientifically admissible studies were summarized and synthesized following best- evidence synthesis methodology . Results Of the 6,359 articles retrieved , 16 r and omized controlled trials were eligible for critical appraisal and five were admissible . We found that a return-to-work coordination program ( including workplace-based work hardening ) was superior to clinic-based work hardening for persistent rotator cuff tendinitis . Workplace high-intensity strength training and workplace advice had similar outcomes for neck and shoulder pain . Mensendieck/Cesar postural exercises and strength and fitness exercises had similar outcomes for non-specific work-related upper limb complaints . Adding a brief job stress education program to a workplace ergonomic intervention was not beneficial for persistent upper extremity symptoms . Adding computer-prompted work breaks to ergonomic adjustments and workplace education benefited workers ’ recovery from recent work-related neck and upper extremity complaints . Conclusions At present , no firm conclusions can be drawn regarding the effectiveness of WDP interventions for managing neck pain , WAD , and upper extremity disorders . Our review suggests a return-to-work coordination program is more effective than clinic-based work hardening . Also , adding computer-prompted breaks to ergonomic and workplace interventions benefits workers ’ recovery . The current quality of evidence does not allow for a definitive evaluation of the effectiveness of ergonomic interventions Background Musculoskeletal disorders ( MSDs ) are the leading cause of work disability and sickness absence worldwide . The prevalence of MSDs increases with age , consequently challenging sustainable employability among the growing ageing workforce . Knowledge of feasible and efficient workplace-based interventions to rehabilitate MSD or prevent its consequences is therefore warranted . This systematic review will evaluate the effectiveness of workplace-based interventions on MSDs and its consequences among adult workers with physical and sedentary work tasks , respectively . Methods We will search the following bibliographic data bases : PubMed ( including the data base ‘ MEDLINE ’ ) and Web of Science Core Collection ( including the data bases ‘ Science Citation Index Exp and ed ’ , ‘ Social Sciences Citation Index ’ and ‘ Arts & Humanities Citation Index ’ ) . Manual search es will also be performed . We will include r and omised controlled trials ( RCTs ) and non- RCTs reported in English in which ( 1 ) participants are adult workers with MSD , ( 2 ) interventions are aim ing at rehabilitating pain symptoms of MSD or preventing the consequences of MSD and ( 3 ) interventions are initiated and /or carried out at the workplace . The review will adhere to the ‘ Preferred Reporting Items for Systematic review s and Meta-Analyses ’ ( PRISMA ) guidelines for reporting systematic review s and the Institute for Work and Health ( IWH ) guidelines for workplace-based interventions . For the primary evaluation of the review , the quality assessment and evidence synthesis will conform to the IWH guidelines . Secondary evaluation will include a meta- analysis ( unless the included studies do not allow this due to heterogeneity ) and employ the risk of bias domains recommended by Cochrane along with the Grading of Recommendations , Assessment , Development and Evaluations ( GRADE ) approach on the studies with pain intensity as an outcome . Discussion This systematic review will provide knowledge on effective workplace-based interventions among physical and sedentary workers with MSD . RCTs are considered the most powerful experimental design in clinical trials , but solely including these may be too restrictive to underst and effective workplace-based interventions where r and omised and carefully controlled trials ( RCTs ) are not always possible . In order to maximize practical relevance , the selection process will , therefore , include both RCTs and non- RCTs and the quality assessment and evidence synthesis will conform to IWH guidelines focusing on developing practical guidelines for stakeholders . The result of this work will form the basis for industry-specific evidence -based recommendations on effective workplace-based interventions for rehabilitation of MSDs and its consequences that will later be operationalised into concrete and user-friendly practical tools for workplaces . Systematic review registration International Prospect i ve Register of Systematic Review s ( PROSPERO ) number CRD42018116752 Purpose Health and safety training program has been applied to prevent work-related  musculoskeletal disorders ( MSDs ) in workplace . We evaluated the effectiveness of participatory training and didactic training programs on MSD prevention among frontline workers in Shenzhen , China . Methods The authors r and omly assigned 918 workers from intervention factories to receive participatory training ( intervention group ) , and 907 workers from intervention factories and 1,654 workers from control factories to receive didactic training ( control_1 group , control_2 group , respectively ) from June 1 , 2008 to November 30 , 2009 . Participants were asked to report experience of ache , pain or discomfort in 10 body parts at baseline and 1 year after training . Data were analyzed to compare the MSD prevalence 1 year before and 1 year after training in different groups from 2009 to 2010 . Results The follow-up rate was 61 % ( 2,120/3,479 ) at 1 year after training . In the year after training , there were no statistically significant changes in the proportion of workers who reported MSD in any body part . MSD prevalence rates in the intervention group reduced from 16.8 to 9.9 % for lower extremities ( χ2 = 13.102 , p < 0.001 ) and from 12.9 to 8.3 % ( χ2 = 9.433 , p = 0.002 ) for wrist and finger at 1 year after training . However , the rates did not change significantly for upper back , lower back , neck , shoulder and elbow in the intervention group and for all 10 body parts in two control groups . Conclusions Overall , the training programs did not seem to prevent the occurrence of MSD among frontline workers . However , participatory training might be effective to reduce MSD in the lower extremities and wrist and finger Purpose The aim of the study was to determine effects of ergonomic intervention on work-related upper extremity musculoskeletal disorders ( WUEMSDs )  among computer workers . Methods Four hundred computer workers answered a question naire on work-related upper extremity musculoskeletal symptoms ( WUEMSS ) . Ninety-four subjects with WUEMSS using computers at least 3 h a day participated in a prospect i ve , r and omized controlled 6-month intervention . Body posture and workstation layouts were assessed by the Ergonomic Question naire . We used the Visual Analogue Scale to assess the intensity of WUEMSS . The Upper Extremity Function Scale was used to evaluate functional limitations at the neck and upper extremities . Health-related quality of life was assessed with the Short Form-36 . After baseline assessment , those in the intervention group participated in a multicomponent ergonomic intervention program including a comprehensive ergonomic training consisting of two interactive sessions , an ergonomic training brochure , and workplace visits with workstation adjustments . Follow-up assessment was conducted after 6 months . Results In the intervention group , body posture ( p < 0.001 ) and workstation layout ( p = 0.002 ) improved over 6 months ; furthermore , intensity ( p < 0.001 ) , duration ( p < 0.001 ) , and frequency ( p = 0.009 ) of WUEMSS decreased significantly in the intervention group compared with the control group . Additionally , the functional status ( p = 0.001 ) , and physical ( p < 0.001 ) , and mental ( p = 0.035 ) health-related quality of life improved significantly compared with the controls . There was no improvement of work day loss due to WUEMSS ( p > 0.05 ) . Conclusions Ergonomic intervention programs may be effective in reducing ergonomic risk factors among computer workers and consequently in the secondary prevention of WUEMSDs Objective The purpose of this study was to describe the availability of preventive devices and training in relation to neck , shoulder , and back musculoskeletal injuries/disorders ( MSD ) in registered nurses . Summary background data Nurses have one of the highest rates of MSD of any occupation . Studies have shown that mechanical lifting devices and lifting teams can reduce MSD rates and associated costs . Methods Data from 1163 r and omly selected currently working nurses ( 1 + years on the current job ) were collected in anonymous mailed surveys ( 74 % response rate ) . MSD cases had neck , shoulder , and /or back symptoms for at least 1 week , or at least monthly , and moderate or more pain , in the past year . Results Nurses with mechanical lifting devices available were significantly less likely to have neck or back MSDs . Back injury was less likely when lifting teams were available . However , adjustable beds and transfer sheets were associated with greater odds of back MSD . Training in workstation adjustment was associated with significantly lower MSD prevalence , though postural training was not . Conclusions Though use of mechanical devices and lifting teams was limited in nursing workplaces , these prevention strategies were related to reduced odds of MSD . Nursing administrators can use these findings to consider workplace changes 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 Spinal Cord Injury Rehabilitation Evidence ( SCIRE ) is a synthesis of the research evidence underlying rehabilitation interventions to improve the health of people living with SCI . SCIRE covers a comprehensive set of topics and in this issue we present six papers relevant to SCI rehabilitation clinicians ( SCI inpatient rehabilitation practice s , gait strategies , upper extremity reconstructive surgery , spasticity treatments , cardiovascular health and bone health ) . The SCIRE used a systematic and well-defined protocol to assess and synthesize the evidence . Each article was scored for its method ological quality using either the Physiotherapy Evidence Data base ( PEDro ) Score for r and omized controlled trials or the Downs and Black Tool for other types of studies . Following the individual study assessment , conclusions were drawn about the accumulated studies for each topic of interest based on the levels of evidence , quality of studies and concurring evidence . The SCIRE project was design ed for health professionals to inform them of best practice 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 There is evidence that performing job tasks involving repetition , vibration , sustained posture or forceful movement may contribute to symptoms of work related upper extremity disorders . Typing is one such activity ; symptoms that develop as a result of this activity can affect performance of work , self-care and leisure occupations . Studies investigating the impact of ergonomic keyboards on symptom reduction are limited , and little research exists regarding the reduction of key activation force as an intervention . Methods : This r and omized , prospect i ve study used a sample of 68 symptomatic workers employed by a single company . One group received a commercially available ergonomic keyboard , a second group used a modified version of the same keyboard design ed to reduce activation force , vibration and key travel . We measured symptoms and clinical signs , functional status , and device satisfaction in both groups over a six-month study period . Results : Between-groups analyses indicated that the groups performed similarly on the outcomes of interest . Repeated-measure analysis identified a reduction of symptoms , an improvement in functional status , preference for and increased satisfaction with the intervention keyboards , and maintenance of typing speed and accuracy for both groups . Conclusions Management of the return-to-work process in cl aim ants with work-related upper extremity disorders often poses challenges to the health care provider , cl aim ant , and employer . Modifying workplace ergonomic risk factors as a component of the workplace accommodation process may improve return-to-work outcomes by reducing recurrent pain and discomfort . The present study is a case-control evaluation of the effects of a 2-day training program for nurse case managers  that was design ed to facilitate the implementation of workplace accommodations within a workers ’ compensation health care delivery system . After the training , 101 cl aim ants with compensable upper extremity disorders were r and omly assigned to case mangers with and without training . Overall , 208 accommodations were recommended and 155 of these were implemented ( 75 % ) . Cl aim ants of trained nurses received 1.5 times as many recommendations for accommodations  as cl aim ants managed by nurses not trained in the process , and 1.4 times as many accommodations were implemented , although no differences were found between the two groups in implementation rates . Trained nurses were more likely to recommend accommodations addressing workstation layout , computer-related improvements , furnishings , accessories , and lifting/carrying aids , whereas the untrained nurses were more likely to suggest light duty and lifting restrictions . This study indicates that the training was associated with a change in the practice behavior of case managers regarding the workplace accommodation process . More research is needed to identify barriers to implementation and develop more effective approaches to facilitate worksite accommodations in disabled workers with carpal tunnel syndrome and other persistent upper extremity disorders 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 Objectives : To study the effectiveness of using a computer mouse with a feedback signal for upper extremity musculoskeletal symptoms in office workers . Methods : A r and omised controlled trial with 8 months of follow-up was carried out . The intervention consisted of a computer mouse with a feedback signal . In total , 354 subjects were allocated to the intervention group or the  control group . Measurements were performed with electronic question naires at baseline , after 4 months and after 8 months . Outcome variables were the prevalence and incidence of upper extremity musculoskeletal symptoms and disability in the upper extremities . The intervention process was evaluated by software registration . Results : The use of the mouse with a feedback signal result ed in a significant decrease in duration of mouse usage over time . No differences were found in the number of mouse usage rest breaks . No differences were found in the prevalence ( p = 0.29 ) or incidence ( p = 0.832 ) of upper extremity musculoskeletal symptoms between the groups 8 months after baseline . The prevalence decreased from 49 % at baseline to 44 % after 8 months in the control group , while it remained at 36 % in the intervention group . The incidence was 21 % in the control group and 22 % in the intervention group . Among the population with upper extremity musculoskeletal symptoms at baseline , the risk of experiencing symptoms after 8 months did not differ between the groups ( p = 0.49 ) . Minor disability was found in both groups . In the intervention group , a lower level of physical disability over time was reported than in the control group ( p = 0.02 ) . Conclusions : A feedback signal computer mouse does not affect the prevalence and incidence of upper extremity musculoskeletal symptoms , but it does lower disability scores . Given the high prevalence , study ing preventive interventions for upper extremity musculoskeletal symptoms is of high importance . Trial registration number : IS RCT N13222474 Compare the effects of integrated case management and usual care on patient satisfaction in employees with work-related upper extremity disorder ( WRUED ) , and consider the implication s of higher levels of satisfaction . Describe those patient-related and work-related factors that predict the severity of upper limb symptoms and the degree of functional limitation 6 and 12 months after intervention . Enumerate the factors influencing the interval before return to work in employees with WRUED who are managed by traditional or integrated case management . An integrated case management ( ICM ) approach ( ergonomic and problem-solving intervention ) to work-related upper-extremity disorders was examined in relation to patient satisfaction , future symptom severity , function , and return to work ( RTW ) .  Federal workers with work-related upper-extremity disorder workers ’ compensation cl aims ( n = 205 ) were r and omly assigned to usual care or ICM intervention .  Patient satisfaction was assessed after the 4-month intervention period . Question naires on clinical outcomes and ergonomic exposure were administered at baseline and at 6- and 12-months postintervention . Time from intervention to RTW was obtained from an administrative data base . ICM group assignment was significantly associated with greater patient satisfaction . Regression analyses found higher patient satisfaction levels predicted decreased symptom severity and functional limitations at 6 months and a shorter RTW . At 12 months , predictors of positive outcomes included male gender , lower distress , lower levels of reported ergonomic exposure , and receipt of ICM . Findings highlight the utility of targeting workplace ergonomic and problem solving skills Background : Call centre work with computers is associated with increased rates of upper body pain and musculoskeletal disorders . Methods : This one year , r and omised controlled intervention trial evaluated the effects of a wide forearm support surface and a trackball on upper body pain severity and incident musculoskeletal disorders among 182 call centre operators at a large healthcare company . Participants were r and omised to receive ( 1  ) ergonomics training only , ( 2 ) training plus a trackball , ( 3 ) training plus a forearm support , or ( 4 ) training plus a trackball and forearm support . Outcome measures were weekly pain severity scores and diagnosis of incident musculoskeletal disorder in the upper extremities or the neck/shoulder region based on physical examination performed by a physician blinded to intervention . Analyses using Cox proportional hazard models and linear regression models adjusted for demographic factors , baseline pain levels , and psychosocial job factors . Results : Post-intervention , 63 participants were diagnosed with one or more incident musculoskeletal disorders  . Hazard rate ratios showed a protective effect of the armboard for neck/shoulder disorders ( HR = 0.49 , 95 % CI 0.24 to 0.97 ) after adjusting for baseline pain levels and demographic and psychosocial factors . The armboard also significantly reduced neck/shoulder pain ( p = 0.01 ) and right upper extremity pain ( p = 0.002 ) in comparison to the control group . A return-on-investment model predicted a full return of armboard and installation costs within 10.6 months . Conclusion : Providing a large forearm support combined with ergonomic training is an effective intervention to prevent upper body musculoskeletal disorders and reduce upper body pain associated with computer work among call centre employees
Levels of evidence for interventions associated with positive effects were : Moderate evidence for arm supports ; and Limited evidence for ergonomics training plus workstation adjustments , new chair and rest breaks .
Levels of evidence for interventions associated with “ no effect ” were : Strong evidence for workstation adjustment alone ; Moderate evidence for biofeedback training and job stress management training ; and Limited evidence for cognitive behavioral training .
No interventions were associated with “ negative effects ” .
Conclusion It is difficult to make strong evidence d-based recommendations about what practitioners should do to prevent or manage upper extremity MSDs .
There is a paucity of high quality OHS interventions evaluating upper extremity MSDs and none focused on traumatic injury outcomes or workplace m and ated pre-placement screening exams .
Background Little is known about the most effective occupational health and safety ( OHS ) interventions to reduce  upper extremity musculoskeletal disorders ( MSDs ) and injuries .
Methods A systematic review used a best evidence synthesis approach to address the question : “ do occupational health and safety interventions have an effect on upper extremity musculoskeletal symptoms , signs , disorders , injuries , cl aims and lost time ? ”
