The Relationship of Role-Related Variables to Job Satisfaction and Commitment to the Organization in a Restructured Hospital Environment
Authors: Lopopolo Rosalie B
Published: February 2017

Background and Purpose. Many factors in today's hospitals can influence how physical therapists view their work experience. Changing roles, with the accompanying stress, and professionalism may contribute to a therapist's perception of his or her job and the organization in which he or she works. In this study, the relationship between changes in physical therapist role behaviors following hospital restructuring and 2 work-related outcomes—job satisfaction and commitment to the organization—was studied. The influence of stress and occupational commitment on these outcomes also was examined. Subjects and Methods. Through a survey of 273 hospital-based physical therapists, changes in physical therapist role behaviors, levels of stress, occupational commitment, job satisfaction, and commitment to the organization following restructuring were identified and examined. Results. Six role behavior dimensions reflecting professional and organizational responsibilities were identified from the data. After controlling for sample demographics, the professional role behaviors, specifically those reflecting interaction and integration with other practitioners, appeared to exert a small, but positive, influence on job satisfaction and commitment to the organization. In addition, occupational commitment had a positive influence, whereas stress had a negative influence on job satisfaction and commitment to the organization. Discussion and Conclusion. Multiple aspects of a clinician's role could influence job satisfaction and commitment to the organization following hospital restructuring. The most influential factor was stress, which often accompanies organizational change. However, the positive influence of occupational commitment and the role behaviors that involve increased interaction with other people were noted and reflect professional role characteristics described in the Guide to Physical Therapist Practice.
Examination of and Intervention for a Patient With Chronic Lateral Elbow Pain With Signs of Nerve Entrapment
Authors: Ekstrom Richard A , Holden Kari
Published: February 2017

Background and Purpose. Lateral elbow pain has several causes, which can make diagnosis difficult. The purpose of this case report is to describe the examination of and the intervention for a patient with chronic lateral elbow pain who had signs of nerve entrapment. Case Description. The patient was a 43-year-old woman who had right lateral elbow pain for about 4 months, which she attributed to extensive keyboard work on a computer. She had a reduction in joint passive range of motion during “neural tension testing,” an examination procedure to detect nerve entrapment. This sign, in combination with other findings, suggested that the patient had a mild entrapment of the deep radial nerve (radial tunnel syndrome). The patient was treated 14 times over a 10-week period with “neural mobilization techniques,” which are designed to free nerves for movement; ultrasound; strengthening exercises; and stretching. Outcomes. The patient had minimal symptoms at discharge, was pain-free, and had resumed all activities at a 4-month follow-up visit. Discussion. Neural tension testing may be a useful examination procedure and mobilization may be useful for intervention for patients who have lateral elbow pain.
Use of the ICF Model as a Clinical Problem-Solving Tool in Physical Therapy and Rehabilitation Medicine
Authors: Steiner Werner A , Ryser Liliane , Huber Erika , Uebelhart Daniel , Aeschlimann André , Stucki Gerold
Published: February 2017

The authors developed an instrument called the “Rehabilitation Problem-Solving Form” (RPS-Form), which allows health care professionals analyze patient problems, to focus on specific targets, and to relate the salient disabilities to relevant and modifiable variables. In particular, the RPS-Form was designed to address the patients' perspectives and enhance their participation in the decision-making process. Because the RPS-Form is based on the International Classification of Functioning, Disability, and Health (ICF) Model of Functioning and Disability, it could provide a common language for the description of human functioning and therefore facilitates multidisciplinary responsibility and coordination of interventions. The use of the RPS-Form in clinical practice is demonstrated by presenting an application case of a patient with a chronic pain syndrome.

Authors: Soroko Yolanta T , Repking Mary C , Clemment Julie A , Mitchell Patricia L , Berg Richard L
Published: February 2017

Background and Purpose. Iontophoretic sodium salicylate treatment of plantar warts was studied. Subjects. Twenty patients with 104 plantar verrucae were studied. Methods. Two percent sodium salicylate solution was administered iontophoretically (22.5 mA-minute/electrode, 3 treatments at 6- to 9-day intervals). Results. Nineteen subjects were followed. Verrucae area declined in 15 subjects (78.9%) and increased in 2 subjects (10.5%). One subject (5.3%) no longer had verrucae, and 1 subject (5.3%) exhibited no change. Overall, the number of verrucae and total area decreased. Four of 6 subjects (66.6%) with initial complaints of load-bearing pain reported diminished pain following treatment. Two subjects whose verrucae's size increased reported an increase in pain at the end of the study. Discussion and Conclusion. Sodium salicylate iontophoresis appeared to compare favorably with other office-based interventions in diminishing the size of plantar warts and their associated pain. Application of iontophoresis to weight-bearing surfaces in some subjects appeared to decrease the pain and scarring associated with freezing and electrocautery and the fixation problems associated with medicated patches.

Authors: Jeng Suh-Fang , Chen Li-Chiou , Yau Kuo-Inn Tsou
Published: February 2017

Background and Purpose. Study of kicking development provides important information to understand how early spontaneous movements change in infants as they acquire voluntary control. Researchers have investigated the kicking movements of preterm infants; however, the movement patterns that they have described were inconsistent. The purpose of this study, therefore, was to examine the development of kicking movements with kinematic analysis in preterm infants with very low birth weight (VLBW) and full-term infants. Subjects and Methods. Twenty-two infants with VLBW who were divided into low gestational age (gestational age of <30 weeks, n=9) and high gestational age (gestational age of ≥30 weeks, n=13) classes and 22 full-term infants were evaluated during kicking movements using 4 synchronized cameras and 3-dimensional kinematic analysis when the infants were 2 and 4 months of corrected age. Results. The infants with VLBW and a high gestational age showed similar kicking movements compared with the full-term infants. In contrast, the infants with VLBW and a low gestational age exhibited a higher kick frequency and a shorter flexion phase at 4 months of corrected age. They also exhibited a higher hip-knee correlation and lower variability in the interlimb coordination pattern at 2 and 4 months of corrected age. Discussion and Conclusion. The findings indicate that infants with VLBW, particularly those with a low gestational age, have age-related differences in movement organization and coordination of kicking compared with full-term infants.
Assessing the Need for Change in Clinical Education Practices
Authors: Strohschein Jennifer , Hagler Paul , May Laura
Published: February 2017

The purposes of this perspective article are to identify areas of need within clinical education, to describe various models and tools that are proposed and utilized in clinical education, and to explore the extent to which these models and tools might meet the identified needs of clinical education. A synthesis of the literature suggests that the clinical education process in physical therapy currently is characterized by 7 primary needs and that 10 models currently exist to guide the general process or to provide specific tools and practices to enhance its effectiveness. Roles and relationships are critical components in successful clinical education. Theory suggests that clinical educators and students should engage in an intentional, structured process of changing roles during the course of the clinical education experience and that nontechnical competencies such as communication, collaboration, and reflection are crucial for effective practice and may be developed in the clinical education setting. Developing a clearer understanding of the current status of physical therapy clinical education can assist clinical educators in the use of the available models and tools or in developing a new model that addresses potentially unique needs.
Relationships Among Lifting Ability, Grip Force, and Return to Work
Authors: Matheson Leonard N , Isernhagen Susan J , Hart Dennis L
Published: February 2017

Background and Purpose. The relationship between functional capacity evaluation (FCE) data and work disability has not been studied. The validity of FCE testing results in terms of subsequent return to work (RTW) was the focus of this exploratory study. Subjects and Methods. Six hundred fifty adults of working age were evaluated as part of a standardized FCE. Clients were contacted by telephone 6 months after the FCE to determine their work status. Predictor variables were gender, age, time off work, maximum safe loads during 3 dynamic lifts, and isometric grip force. Other variables measured were whether or not the client returned to work (RTW-Y/N) and level of return to work (RTW level). Results. A multivariate logistic regression analysis demonstrated that the more time a worker was away from work, the less likely was RTW. Male subjects were less likely to return to work than female subjects. The more weight lifted from floor to waist, the more likely was RTW. The logistic regression equation correctly classified 80.3% of the subjects who returned to work and 56.6% of the subjects who did not return to work. Each of the 3 lift tests was related to RTW level, whereas the grip force tests were not related to either RTW-Y/N or RTW level. Discussion and Conclusion. Time off work and gender were the strongest predictors of RTW, but certain FCE subtests of lifting were related to RTW and RTW level for people with work-related chronic symptoms. Grip force was not related to RTW.
Reliability of Safe Maximum Lifting Determinations of a Functional Capacity Evaluation
Authors: Gross Douglas P , Battié Michele C
Published: February 2017

Background and Purpose. Functional capacity evaluations (FCEs) are measurement tools used in predicting readiness to return to work following injury. The interrater and test-retest reliability of determinations of maximal safe lifting during kinesiophysical FCEs were examined in a sample of people who were off work and receiving workers' compensation. Subjects. Twenty-eight subjects with low back pain who had plateaued with treatment were enrolled. Five occupational therapists, trained and experienced in kinesiophysical methods, conducted testing. Methods. A repeated-measures design was used, with raters testing subjects simultaneously, yet independently. Subjects were rated on 2 occasions, separated by 2 to 4 days. Analyses included intraclass correlation coefficients (ICCs) and 95% confidence intervals. Results. The ICC values for interrater reliability ranged from .95 to .98. Test-retest values ranged from .78 to .94. Discussion and Conclusion. Inconsistencies in subjects' performance across sessions were the greatest source of FCE measurement variability. Overall, however, test-retest reliability was good and interrater reliability was excellent.
Effect of Duration of Upper- and Lower-Extremity Rehabilitation Sessions and Walking Speed on Recovery of Interlimb Coordination in Hemiplegic Gait
Authors: Kwakkel Gert , Wagenaar Robert C
Published: February 2017

Background and Purpose. The effects of different durations of rehabilitation sessions for the upper extremities (UEs) and lower extremities (LEs) on the recovery of interlimb coordination in hemiplegic gait in patients who have had a stroke were investigated. Subjects and Methods. Fifty-three subjects who had strokes involving their middle cerebral arteries were assigned to rehabilitation programs with (1) an emphasis on the LEs, (2) an emphasis on the paretic UE, or (3) a condition in which the paretic arm (UE) and leg (LE) were immobilized with an inflatable pressure splint (control treatment). The 3 treatment regimens were applied for 30 minutes, 5 days a week, during the first 20 weeks after onset of stroke. All subjects also participated in a rehabilitation program 5 days a week that consisted of 15 minutes of UE exercises and 15 minutes of LE exercises in addition to a weekly 1½-hour session of training in activities of daily living. A repeated-measures design was used. Differences among the 3 treatment regimens were evaluated in terms of comfortable and maximal walking speeds. In addition, mean continuous relative phase (CRP) between paretic arm and leg (PAL) movements and nonparetic arm and leg (NAL) movements and standard deviations of CRP of both limb pairs as a measurement of stability (variability) were evaluated. Results. Comfortable walking speed improved in the group that received interventions involving the LEs compared with the group that received interventions involving the UEs and the group that received the control treatment. No differences among the 3 treatment conditions were found for the mean CRP of NAL and PAL as well as the standard deviation of CRP of both limb pairs. Discussion and Conclusion. With the exception of an improved comfortable walking speed as a result of a longer duration of rehabilitation sessions, no differential effects of duration of rehabilitation sessions for the LEs and UEs on the variable we measured related to hemiplegic gait were found. Increasing walking speed, however, resulted in a larger mean CRP for both limb pairs, with increased stability and asymmetry of walking, indicating that walking speed influences interlimb coordination in hemiplegic gait.
Changes in Abduction and Rotation Range of Motion in Response to Simulated Dorsal and Ventral Translational Mobilization of the Glenohumeral Joint
Authors: Hsu Ar-Tyan , Hedman Tom , Chang Jia Hao , Vo Chuong , Ho Larry , Ho Sally , Chang Guan-Liang
Published: February 2017

Background and Purpose. Translational mobilization techniques are frequently used by physical therapists as an intervention for patients with limited ranges of motion (ROMs). However, concrete experimental support for such practice is lacking. The purpose of the study was to evaluate the effect of simulated dorsal and ventral translational mobilization (DTM and VTM) of the glenohumeral joint on abduction and rotational ROMs. Methods. Fourteen fresh frozen shoulder specimens from 5 men and 3 women (mean age=77.3 years, SD=10.1, range=62–91) were used for this study. Each specimen underwent 5 repetitions of DTM and VTM in the plane of scapula simulated by a material testing system (MTS) in the resting position (40° of abduction in neutral rotation) and at the end range of abduction with 100 N of force. Abduction and rotation were assessed as the main outcome measures before and after each mobilization procedure performed and monitored by the MTS (abduction, 4 N·m) and by a servomotor attached to the piston of the actuator of the MTS (medial and lateral rotation, 2 N·m). Results. There were increases in abduction ROM for both DTM (X̄=2.10°, SD=1.76°) and VTM (X̄=2.06°, SD=1.96°) at the end-range position. No changes were found in the resting position following the same procedure. Small increases were also found in lateral rotation ROM after VTM in the resting position (X̄=0.90°, SD=0.92°, t=3.65, P=.003) and in medial rotation ROM after DTM (X̄=0.97°, SD=1.45°, t=2.51, P=.026) at the end range of abduction. Discussion and Conclusion. The results indicate that both DTM and VTM procedures applied at the end range of abduction improved glenohumeral abduction range of motion. Whether these changes would result in improved function could not be determined because of the use of a cadaver model.
Gait Initiation in Community-Dwelling Adults With Parkinson Disease: Comparison With Older and Younger Adults Without the Disease
Authors: Martin Matthew , Shinberg Mindi , Kuchibhatla Maggie , Ray Laurie , Carollo James J , Schenkman Margaret L
Published: February 2017

Background and Purpose. Initiation of gait requires transitions from relatively stationary positions to stability with movement and from double- to single-limb stances. These are deliberately destabilizing activities that may be difficult for people with early Parkinson disease (PD), even when they have no problems with level walking. We studied differences in postural stability during gait initiation between participants with early and middle stages of PD (characterized by Hoehn and Yahr as stages 1–3) and 2 other groups of participants without PD—older and younger adults. Subjects. The mean ages of the 3 groups of participants were as follows: subjects with PD, 69.3 years (SD=5.7, range=59–78); older subjects without PD, 69.0 years (SD=3.9, range=65–79); and younger subjects without PD, 27.5 (SD=3.9, range=22–35). Methods. A 3-dimensional motion analysis system was used with 2 force platforms to obtain data for center of mass (COM) and center of pressure (COP). The distance between the vertical projections of the COM and the COP (COM–COP distance) was used to reflect postural control during 5 events in gait initiation. Results. By use of multivariate analysis of variance, differences in COM–COP distance were found among the 3 groups. An analysis of variance indicated differences for 4 of the 5 events in gait initiation. A Scheffe post hoc analysis demonstrated differences in gait initiation between the subjects with PD and both groups of subjects without PD (2 events) and between the subjects with PD and the younger subjects without PD (2 events). Discussion and Conclusion. The COM–COP distance relationship was used to measure postural control during the transition from quiet standing to steady-state gait. Differences between groups indicated that individuals with impaired postural control allow less COM–COP distance than do individuals with no known neurologic problems. The method used could prove useful in the development and assessment of interventions to improve ambulation safety and enhance the independence of people with impaired postural control.
Glossopharyngeal and Neck Accessory Muscle Breathing in a Young Adult With C2 Complete Tetraplegia Resulting in Ventilator Dependency
Authors: Warren Valerie C
Published: February 2017

Background and Purpose. This case report describes the use of glossopharyngeal breathing (GPB) and neck accessory muscle breathing (NAMB) in the treatment of an individual who was dependent on a ventilator secondary to a spinal cord injury. Case Description. The patient was a 19-year-old man with C2 complete tetraplegia. He received a 5-week inpatient program of GPB training 3 to 4 times per week. A 4-week NAMB training program followed. Outcome. Following GPB training, forced vital capacity increased 35-fold, time off the ventilator improved from 0 to 30 minutes, and a nonfunctional cough became a weak functional cough. After NAMB training, the patient was able to be off the ventilator for 2 minutes. Discussion. Increased ventilatory capability has the potential to affect patients' quality of life by improving cough function and decreasing dependence on a ventilator in the event of accidental disconnection.

Authors: Blau Rosemary , Bolus Sarah , Carolan Terrence , Kramer Daniel , Mahoney Elizabeth , Jette Diane U , Beal Judy A
Published: February 2017

Background and Purpose. The changes in the health care environment during the last decade have had an impact on the roles and responsibilities of all health care professionals. The purpose of this phenomenological study was to describe the experience of staff physical therapists during a time of systemic change within a large urban academic medical center. Subjects and Methods. Participants were 5 physical therapists working in various clinical settings within the medical center. The participants were interviewed and asked the question “Over the past 4 years, there have been major changes in your work environment. What has it been like for you working as a clinician during this time of change?” Interviews were recorded, transcribed, and analyzed to find thematic patterns of responses. Results. Four common themes emerged in which participants described experiencing loss of control, stress, discontent, and disheartenment. A fifth theme showed that despite these negative feelings, participants were able to “find the silver lining” in their daily work lives (ie, they were able to find positive aspects of their professional lives despite the perceived unpleasant changes with which they had to cope). Discussion and Conclusion. This study provides insight into the experiences of a group of staff physical therapists during a time of systemic change in their work environment. Although the themes reflect largely unsettling and negative experiences, there seems to be an underlying ability to find affirmative aspects of work.
A Retrospective Analysis of Ethics Knowledge in Physical Therapy (1970–2000)
Authors: Swisher Laura Lee
Published: February 2017

Background and Purpose. Purtilo, Guccione, and others have noted that increased clinical autonomy for physical therapists presents more complex ethical dilemmas. The body of literature examining physical therapy ethics, however, is relatively small and has not been analyzed. The primary purposes of this research were: (1) to use multiple perspectives to describe and analyze literature examining ethics in physical therapy from 1970 to 2000, (2) to develop a model to describe the evolution of knowledge of ethics in physical therapy during this period, and (3) to compare the proposed model with the evolutionary models proposed by Purtilo in physical therapy and by Pellegrino in bioethics. Sample. The sample consisted of peer-reviewed journal articles cited in the MEDLINE or Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases between 1970 and 2000 or referenced in Ethics in Physical Therapy. Methods. A two-phase mixed quantitative and qualitative method was used to analyze publications. In the quantitative phase, the author sorted publications into a priori categories, including approach to ethics, author, decade, country of publication, role of the physical therapist, and component of morality. During the qualitative phase of the research, the author analyzed and sorted the publications to identify common themes, patterns, similarities, and evolutionary trends. These findings were compared with the evolutionary models of Pellegrino and Purtilo. Results. The 90 publications meeting inclusion criteria were predominantly philosophical, using the “principles” perspective; focused on the patient/client management role of the physical therapist; and addressed the moral judgment component of moral behavior. As predicted by Purtilo's model, the focus of identity evolved from self-identity to patient-focused identity, with increasing representation of societal identity. Recurrent themes included the need to further identify and clarify physical therapists' ethical dilemmas, the interrelationship between clinical and ethical decision making, and the changing relationship with patients. Discussion and Conclusion. Although knowledge of ethics grew steadily between 1970 and 2000, this retrospective analysis identified gaps in our current knowledge. Further research is needed to address the unique ethical problems commonly encountered in all 5 roles of the physical therapist; patient perspectives on ethical issues in physical therapy; variety in ethical approaches; factors affecting moral judgment, sensitivity, motivation, and courage; and cultural dimensions of ethical practice in physical therapy.
Improved Intralimb Coordination in People With Incomplete Spinal Cord Injury Following Training With Body Weight Support and Electrical Stimulation
Authors: Field-Fote Edelle Carmen , Tepavac Dejan
Published: February 2017

Background and Purpose. Limb coordination is an element of motor control that is frequently disrupted following spinal cord injury (SCI). The authors assessed intralimb coordination in subjects with SCI following a 12-week program combining body weight support, electrical stimulation, and treadmill training. Subjects. Fourteen subjects with long-standing (mean time post-SCI=70 months, range=12–171 months), incomplete SCI participated. Three subjects without SCI provided data for comparison. Methods. A vector-based technique was used to assign values to the frame-by-frame changes in hip/knee angle, and vector analysis techniques were used to assess how closely the hip/knee angles of each step cycle resembled those of every other step cycle. Overground and treadmill walking speeds also were measured. Results. Following training, 9 of the 14 subjects with SCI demonstrated greater intercycle agreement. Mean overground and treadmill walking speeds improved (84% and 158%, respectively). Discussion and Conclusion. The intervention used in this study is based on our current understanding of the role of afferent input in the production of walking. Although the study sample was small and there was no control group, results suggest that training may improve intralimb coordination in people with SCI.
Physical Impairment and Disability: Relationship to Performance of Activities of Daily Living in Community-Dwelling Older Men
Authors: Brach Jennifer S , VanSwearingen Jessie M
Published: February 2017

Background and Purpose. The decline of physical function of older adults, associated with loss of independent living status, is a major public health concern. The purpose of this study was to examine the relationship of physical impairment and disability to performance of activities of daily living (ADL) among community-dwelling older adults. Subjects and Methods. Eighty-three community-dwelling older men who were referred to a comprehensive outpatient geriatric evaluation program (mean age=75.5 years, SD=7.0, range=64–97) were examined. Measurements of physical impairment (muscle force production, flexibility, and fitness) and physical disability (gait speed, stride length, risk for recurrent falls, and physical function) were recorded. Results. A stepwise linear regression was used to determine the relationship of physical impairments and disability measures with ADL. The results indicated that walking speed, fall risk, and muscle force contributed independently to the characterization of the activities of daily living of the community-dwelling older men studied (adjusted R2=.68; F=56.81; df=3,80; P<.001). Using a principal components factor analysis, 4 domains were identified that explained 68.2% of the variance in performance of ADL: (1) mobility/fall risk=26.5%, (2) coordination=15%, (3) fitness=14.7%, and (4) flexibility=12.0%. Discussion and Conclusion. The identification of domains of physical function may be useful to physical therapists in the development of interventions targeted for physical impairments and disabilities that contribute to deficits in performance of ADL. Targeting interventions for physical impairments and disabilities related to function may improve the effectiveness of physical therapist interventions and reduce the loss of independence among community-dwelling older people.
Evaluation of the Presence of Sacroiliac Joint Region Dysfunction Using a Combination of Tests: A Multicenter Intertester Reliability Study
Authors: Riddle Daniel L , Freburger Janet K ,   North American Orthopaedic Rehabilitation Research Network
Published: February 2017

Background and Purpose. The authors examined the intertester reliability of assessments made based on a composite of 4 tests of pelvic symmetry or sacroiliac joint (SIJ) movement that are advocated in the literature for identifying people with SIJ region dysfunction. “Sacroiliac joint region dysfunction” is a term used to describe pain in or around the region of the joint that is presumed to be due to malalignment or abnormal movement of the SIJs. Subjects. Sixty-five patients with low back pain and unilateral buttock pain were seen in 1 of 11 outpatient clinics. Methods. Thirty-four therapists, randomly paired for each subject, served as examiners. Kappa coefficients and observed proportions of positive (Ppos) and negative (Pneg) agreement were calculated to estimate reliability. Results. For the composite test results, percentages of agreement ranged from 60% to 69%, kappa coefficients varied from .11 to .23, and Ppos was lower than 50%. Discussion and Conclusion. Reliability of measurements obtained with the 4 tests appears to be too low for clinical use. Given the measurement error found in this study, the authors suspect it is likely that either the proper treatment technique will not be chosen based on the test results or the intervention will be applied to the wrong side. The 4 tests probably should not be used to examine patients suspected of having SIJ region dysfunction, although the role of therapist training in use of the procedures is unclear.
The Effects of a Progressive Exercise Program With Surface Electromyographic Biofeedback on an Adult With Fecal Incontinence
Authors: Coffey Stephanie Weiss , Wilder Elaine , Majsak Michael J , Stolove Renee , Quinn Lori
Published: February 2017

Background and Purpose. Fecal incontinence often compromises a person's ability to participate in work and recreational activities. Incontinence may also diminish a person's willingness to take part in social events, leading to feelings of isolation. This case report describes physical therapy designed to reduce a patient's pelvic-floor muscle dysfunction and fecal incontinence. Case Description. The patient was a 30-year-old woman whose fecal incontinence began after the complicated vaginal birth of her first child that required a vacuum extraction and episiotomy. Intervention included soft tissue techniques, electromyographic biofeedback, strength training, relaxation training, patient education, and a home program. The patient completed a questionnaire at initial evaluation and at discharge to assess her perceived limitations in functional activities. Electromyographic analysis was used to measure changes in the patient's pelvic-floor muscle control. Outcomes. The social, occupational, and sexual domains, which the patient initially judged to be the most compromised, showed the greatest improvement. Electromyographic data for the final treatment session indicated improved strength, endurance, and control of her pelvic-floor muscles. The patient reported no episodes of fecal incontinence over the last month of the 3 months of therapy. Discussion. The physical therapy program may have led to improved bowel continence and greater control of the pelvic-floor muscles, resulting in greater confidence and comfort in social and work situations and less restriction in the patient's physical relationship with her spouse.
Determinants of the Sit-to-Stand Movement: A Review
Authors: Janssen Wim GM , Bussmann Hans BJ , Stam Henk J
Published: February 2017

Background and Purpose. The sit-to-stand (STS) movement is a skill that helps determine the functional level of a person. Assessment of the STS movement has been done using quantitative and semiquantitative techniques. The purposes of this study were to identify the determinants of the STS movement and to describe their influence on the performance of the STS movement. Methods. A search was made using MEDLINE (1980–2001) and the Science Citation Index Expanded of the Institute for Scientific Information (1988–2001) using the key words “chair,” “mobility,” “rising,” “sit-to-stand,” and “standing.” Relevant references such as textbooks, presentations, and reports also were included. Of the 160 identified studies, only those in which the determinants of STS movement performance were examined using an experimental setup (n=39) were included in this review. Results. The literature indicates that chair seat height, use of armrests, and foot position have a major influence on the ability to do an STS movement. Using a higher chair seat resulted in lower moments at knee level (up to 60%) and hip level (up to 50%); lowering the chair seat increased the need for momentum generation or repositioning of the feet to lower the needed moments. Using the armrests lowered the moments needed at the hip by 50%, probably without influencing the range of motion of the joints. Repositioning of feet influenced the strategy of the STS movement, enabling lower maximum mean extension moments at the hip (148.8 N·m versus 32.7 N·m when the foot position changed from anterior to posterior). Discussion and Conclusion. The ability to do an STS movement, according to the research reviewed, is strongly influenced by the height of the chair seat, use of armrests, and foot position. More study of the interaction among the different determinants is needed. Failing to account for these variables may lead to erroneous measurements of changes in STS performance.
The Effect of Prolonged Static and Cyclic Stretching on Ankle Joint Stiffness, Torque Relaxation, and Gait in People With Stroke
Authors: Bressel Eadric , McNair Peter J
Published: February 2017

Background and Purpose. Continuous passive motion (cyclic stretching applied to the subject's limb) has been used for the rehabilitation of some orthopedic impairments; however, few researchers have considered its application in the management of neurological disorders such as stroke. The purpose of this study was to examine the short-term effects of prolonged static and cyclic calf stretching on passive ankle joint stiffness, torque relaxation, and gait in people with ischemic stroke. Subjects. Ten community-dwelling people (mean age=64.6 years, SD=8.76, range=53–76) who were diagnosed with a cerebrovascular accident volunteered to be subjects. Methods. Participants engaged in one 30-minute static stretch and one 30-minute cyclic stretch of the calf muscle, using an isokinetic dynamometer that also collected torque and angle measurements. Before and after treatments, 10-m walking times were collected. Ankle joint stiffness was calculated from the slope of the torque and angle curves before and immediately after treatments, and torque relaxation was calculated as the percentage of decrease in peak passive torque over the 30-minute stretch durations. Results. Ankle joint stiffness decreased by 35% and 30% after the static and cyclic stretches, respectively. Stiffness values and 10-m walk times were not different between conditions. The amount of torque relaxation was 53% greater for static stretching than for cyclic stretching. Discussion and Conclusion. These preliminary data from a very small sample of people with stroke indicate that ankle joint stiffness decreases after both prolonged static and cyclic stretches; however, neither technique appears to be better at reducing stiffness in people with stroke. Torque relaxation is greater after static stretching than after cyclic stretching, and walking speed does not appear to be influenced by the stretching treatments used in our study.

Published: February 2017

Background and Purpose. Recent evidence indicates that intensive massed practice may be necessary to modify neural organization and effect recovery of motor skills in patients following stroke. Virtual reality (VR) technology has the capability of creating an interactive, motivating environment in which practice intensity and feedback can be manipulated to create individualized treatments to retrain movement. Case Description. Three patients (ML, LE, and DK), who were in the chronic phase following stroke, participated in a 2-week training program (3½ hours a day) including dexterity tasks on real objects and VR exercises. The VR simulations were targeted for range of motion, movement speed, fractionation, and force production. Outcomes. ML's function was the most impaired at the beginning of the intervention, but showed improvement in the thumb and fingers in range of motion and speed of movement. LE improved in fractionation and range of motion of his thumb and fingers. DK made the greatest gains, showing improvement in range of motion and strength of the thumb, velocity of the thumb and fingers, and fractionation. Two of the 3 patients improved on the Jebsen Test of Hand Function. Discussion. The outcomes suggest that VR may be useful to augment rehabilitation of the upper limb in patients in the chronic phase following stroke.

Authors: Houghton Pamela E , Kincaid Cynthia B , Lovell Marge , Campbell Karen E , Keast David H , Woodbury M Gail , Harris Kenneth A
Published: February 2017

Background and Purpose. Electrical current has been recommended for use on chronic pressure ulcers; however, the ability of this modality to improve healing of other types of chronic ulcers is less well established. The purpose of this study was to examine the effect of high-voltage pulsed current (HVPC) on healing of chronic leg ulcers. Subjects. Twenty-seven people with 42 chronic leg ulcers participated in the study. Methods. The subjects were separated into subgroups according to primary etiology of the wound (diabetes, arterial insufficiency, venous insufficiency) and then randomly assigned to receive either HVPC (100 microseconds, 150 V, 100 Hz) or a sham treatment for 45 minutes, 3 times weekly, for 4 weeks. Wound surface area and wound appearance assessed during an initial examination, following a 1- to 2-week period during which subjects received only conventional wound therapy, after 4 weeks of sham or HVPC treatment, and at 1 month following treatments. Results The results indicated that HVPC applied to chronic leg ulcers reduced the wound surface area over the 4-week treatment period to approximately one half the initial wound size (mean decrease=44.3%, SD=8.8%, range=2.8%-100%), which was over 2 times greater than that observed in wounds treated with sham units (mean decrease=16.0%, SD=8.9%, range=-30.3%-83.7%). Discussion and Conclusion. The results of the study indicate that HVPC administered 3 times a week should be considered to accelerate wound closure of chronic leg ulcers.
The Relationship of Lower-Extremity Muscle Torque to Locomotor Performance in People With Stroke

Background and Purpose. Improved walking is a common goal after stroke. The purpose of this study was to examine the relationship between the torque generated by the muscles of both lower extremities and 2 locomotor tasks: gait on level surfaces and stair climbing in people who had strokes. Subjects. Twenty community-dwelling individuals (mean age=61.2 years, SD=8.4, range=52-82) who had strokes and who were able to walk independently participated in the study. The mean time since stroke was 4.0 years (SD=2.6, range=1.5-10.0). Methods. Pearson correlations and multiple regression were used to measure the relationship between concentric isokinetic torque of the flexor and extensor muscles of the hip, knee, and ankle bilaterally and locomotor performance (gait on level surfaces and stair-climbing speed). Results. The isokinetic torques of the paretic ankle plantar flexors, hip flexors, and knee flexors had moderate to high correlations (r=.5-.8) with gait and stair-climbing speeds. Muscle force could explain 66% to 72% of the variability in gait and stair-climbing speeds. Correlations for the nonparetic side were as high as or higher than those for the paretic side for some muscle groups. Discussion and Conclusion. Muscle performance measurements of both limbs should be included in the evaluation of locomotion and treatment of people following a stroke.

Background and Purpose. The purpose of this case report is to describe an occupational rehabilitation program for a person whose work-related inguinal hernia was surgically repaired. Case Description. A 35-year-old baggage service attendant acquired an inguinal hernia while lifting at work. Postoperatively, the patient had discomfort in the groin, weakness of the lower extremities and trunk, limited ability to walk, and a decreased ability to work due to impaired tolerance.Outcomes. Following postoperative rehabilitation, the patient was able to return to full-time, full-duty work. Discussion. This case report describes occupational rehabilitation as a method to treat patients with work-related inguinal hernias following surgical repair.
Lumbar Posture—Should It, and Can It, Be Modified? A Study of Passive Tissue Stiffness and Lumbar Position During Activities of Daily Living
Authors: Scannell Joan P , McGill Stuart M
Published: February 2017

Background and Purpose. Physical therapists commonly attempt to reduce and prevent low back pain by “improving” individuals' lumbar posture. To investigate the physical therapy clinical practice of attempting to “improve” lumbar posture, measures of passive tissue stiffness and angular deformation during activities of daily living were used. Participants. The lumbar spine posture of 150 university students was measured as the inclinometer angle difference between L1 and S1. Eighteen female participants (6 with hypolordosis, 6 with hyperlordosis, and 6 controls without lumbar spine impairment) were recruited from this lumbar posture database. Hypolordosis and hyperlordosis were clinically classified by physical therapists. Methods. Lumbar passive tissue stiffness was measured during sitting, standing, and walking before and after a 12-week exercise program, and estimates of lumbar passive tissue strain were calculated from those measurements. Results. The neutral zone (NZ), a range of lumbar positions of low passive tissue stiffness, was identified. Prior to training, the subjects with hypolordosis had more passive tissue strain during sitting than the subjects with hyperlordosis, and the subjects with hyperlordosis stood in extension relative to their NZs while the control subjects and subjects with hypolordosis stood within their NZs. Before and after training, subjects in all 3 groups walked with lumbar spine positions within their NZs. After training, the lumbar posture of the subjects with hypolordosis and the subjects with hyperlordosis changed toward a “mean” (mid-range) lumbar posture. After the exercise program, subjects in all 3 groups stood and walked with their lumbar spines in positions within their NZs, and they sat with their lumbar spines flexed relative to their NZs. Discussion and Conclusion. Knowing that tissue failure can be related to passive tissue strain, the results of this study support the clinical practice of attempting to change individuals' posture-related lumbar spine positions during activities of daily living. Lumbar passive tissue strain, as estimated from the NZ and angular deformation during activities of daily living, can be decreased, but can also be increased, by an exercise program.
