Evaluating Physical Therapists' Perception of Empowerment Using Kanter's Theory of Structural Power in Organizations
Authors: Miller Patricia A , Goddard Peggy , Spence Laschinger Heather K 
Published: February 2017

Abstract
Background and Purpose. Little is known about physical therapists' perceptions of empowerment. In this study, Kanter's theory of structural power in organizations was used to examine physical therapists' perceptions of empowerment in a large Canadian urban teaching hospital. Kanter's theory, which has been studied extensively in the nursing profession, proposes that power in organizations is derived from access to information, support, resources, opportunity, and proportions. Subjects and Methods. A convenience sample of physical therapists who had been working in the hospital longer than 3 months was used to determine the scores for the physical therapists' ratings of empowerment using the Conditions of Work Effectiveness Questionnaire. Results. Physical therapists' scores were similar to reported staff nurses' scores for access to support, information, resources, and opportunity (X̄=2.89, 2.91, 2.62, 3.25, respectively). Physical therapists' scores were higher than the majority of reported staff nurses' and nurse managers' scores for access to sources of informal and formal power structures (X̄=2.81 and 3.29, respectively). There was a relationship between the empowerment score and the physical therapists' global rating of empowerment. Unlike studies of nurses, there were no relationships when demographic attributes and empowerment scores were examined. Discussion and Conclusion. Evidence for the validity of Kanter's theory of empowerment was found. Kanter's theory can provide physical therapists and their managers with a useful framework for examining critical organizational factors (access to information, support, opportunity, and resources) that contribute to employees' perceptions of empowerment. A baseline measure for comparing future empowerment scores of this sample is available. Further work to examine the application of Kanter's theory to other samples of physical therapists appears to be warranted.

Authors: Fritz Julie M , Irrgang James J 
Published: February 2017

Abstract
Background and Purpose. The quality of a disability scale should dictate when it is used. The purposes of this study were to examine the validity of a global rating of change as a reflection of meaningful change in patient status and to compare the measurement properties of a modified Oswestry Low Back Pain Disability Questionnaire (OSW) and the Quebec Back Pain Disability Scale (QUE). Subjects. Sixty-seven patients with acute, work-related low back pain referred for physical therapy participated in the study. Methods. The 2 scales were administered initially and after 4 weeks of physical therapy. The Physical Impairment Index, a measure of physical impairment due to low back pain, was measured initially and after 2 and 4 weeks. A global rating of change survey instrument was completed by each subject after 4 weeks. Results. An interaction existed between patients defined as improved or stable based on the global rating using a 2-way analysis of variance for repeated measures on the impairment index. The modified OSW showed higher levels of test-retest reliability and responsiveness compared with the QUE. The minimum clinically important difference, defined as the amount of change that best distinguishes between patients who have improved and those remaining stable, was approximately 6 points for the modified OSW and approximately 15 points for the QUE. Conclusion and Discussion. The construct validity of the global rating of change was supported by the stability of the Physical Impairment Index across the study period in patients defined as stable by the global rating and by the decrease in physical impairment across the study period in patients defined as improved by the global rating. The modified OSW demonstrated superior measurement properties compared with the QUE.
Measurement of Scapular Asymmetry and Assessment of Shoulder Dysfunction Using the Lateral Scapular Slide Test: A Reliability and Validity Study
Authors: Odom Corrie J , Taylor Andrea B , Hurd Christine E , Denegar Craig R 
Published: February 2017

AbstractBackground and Purpose. The Lateral Scapular Slide Test (LSST) is used to determine scapular position with the arm abducted 0, 45, and 90 degrees in the coronal plane. Assessment of scapular position is based on the derived difference measurement of bilateral scapular distances. The purpose of this study was to assess the reliability of measurements obtained using the LSST and whether they could be used to identify people with and without shoulder impairments. Subjects. Forty-six subjects ranging in age from 18 to 65 years (X̄=30.0, SD=11.1) participated in this study. One group consisted of 20 subjects being treated for shoulder impairments, and one group consisted of 26 subjects without shoulder impairments. Methods. Two measurements in each test position were obtained bilaterally. From the bilateral measurements, we derived the difference measurement. Intraclass correlation coefficients (ICC [1,1]) and the standard error of measurement (SEM) were calculated for intrarater and interrater reliability of the difference in side-to-side measures of scapular distance. Sensitivity and specificity of the LSST for classifying subjects with and without shoulder impairments were also determined. Results. The ICCs for intrarater reliability were .75, .77, and .80 and .52, .66, and .62, respectively, for subjects without and with shoulder impairments in 0, 45, and 90 degrees of abduction. The ICCs for interrater reliability were .67, .43, and .74 and .79, .45, and .57, respectively, for subjects without and with shoulder impairments in 0, 45 and 90 degrees of abduction. The SEMs ranged from 0.57 to 0.86 cm for intrarater reliability and from 0.79 to 1.20 cm for interrater reliability. Using the criterion of greater than 1.0 cm difference, sensitivity and specificity were 35% and 48%, 41% and 54%, and 43% and 56%, respectively, for 0, 45, and 90 degrees of abduction. Sensitivity and specificity based on the criterion of greater than 1.5 cm difference were 28% and 53%, 50% and 58%, and 34% and 52%, respectively, for the 3 scapular positions. Conclusion and Discussion. Our results suggest that measurements of scapular positioning based on the difference in side-to-side scapular distance measures are not reliable. Furthermore, the results suggest that sensitivity and specificity of the LSST measurements are poor and that the LSST should not be used to identify people with and without shoulder dysfunction.
Reliability of Measurements Obtained With the Timed “Up & Go” Test in People With Parkinson Disease
Authors: Morris Susan , Morris Meg E , Iansek Robert 
Published: February 2017

Abstract
Background and Purpose. The Timed “Up & Go” Test (TUG) is used to measure the ability of patients to perform sequential locomotor tasks that incorporate walking and turning. This study investigated the retest reliability, interrater reliability, and sensitivity of TUG scores in detecting changes in mobility in subjects with idiopathic Parkinson disease (PD). Subjects. The performance of 12 people with PD was compared with that of 12 age-matched comparison subjects without PD. Methods. The subjects with PD completed 5 trials of the TUG after withdrawal of levodopa for 12 hours (“off” phase of the medication cycle) as well as an additional 5 trials 1 hour after levodopa was administered (“on” phase of the medication cycle). They were scored on the Modified Webster Scale at both sessions. The comparison subjects also performed 5 TUG trials. All trials were videotaped and timed by 2 experienced raters. The videotape was later rated by 3 experienced clinicians and 3 inexperienced clinicians. Results. For the subjects with PD, within-session performance was highly consistent, with correlations (r) ranging from .80 to .98 for the “off” phase and from .73 to .99 for the “on” phase. The performance of the comparison subjects across the 5 trials was also highly consistent (r=.90–.97). Comparisons showed differences between trials 1 and 2 on the TUG for both groups. Removal of data for trial 1 (the practice trial) further enhanced retest reliability. There was close agreement in TUG scores among raters despite different levels of experience (intraclass correlation coefficient [3,1]=.87–.99). Mean TUG scores were different between the “on” and “off” phases of the levodopa cycle and between subjects with PD and comparison subjects during the “on” phase. Conclusion and Discussion. Retest reliability and interrater reliability of the TUG measurements were high, and the measurements reflected changes in performance according to levodopa use. The TUG can also be used to detect differences in performance between people with PD and elderly people without PD.
Gait Re-education Based on the Bobath Concept in Two Patients With Hemiplegia Following Stroke
Authors: Lennon Sheila 
Published: February 2017

Abstract
Background and Purpose. This case report describes the use of gait re-education based on the Bobath concept to measure the changes that occurred in the gait of 2 patients with hemiplegia who were undergoing outpatient physical therapy. Case Description. One patient (“NM”), a 65-year-old woman, was referred for physical therapy 6 weeks following a right cerebrovascular accident. She attended 30 therapy sessions over a 15-week period. The other patient (“SA”), a 71-year-old woman, was referred for physical therapy 7 weeks following a left cerebrovascular accident. She attended 28 therapy sessions over a 19-week period. Clinical indexes of impairment and disability and 3-dimensional gait data were obtained at the start of treatment and at discharge. Therapy was based on the Bobath concept. Outcomes. At discharge, NM demonstrated improvements in her hip and knee movements, reduced tone, and improved mobility. At discharge, SA demonstrated improved mobility. During gait, both patients demonstrated more normal movement patterns at the level of the pelvis, the knee, and the ankle in the sagittal plane. SA also demonstrated an improvement in hip extension. Discussion. These cases demonstrate that recovery of more normal movement patterns and functional ability can be achieved following a cardiovascular accident and provide insight into the clinical decision making of experienced practitioners using Bobath's concept.
Exercise Combined With Continuous Passive Motion or Slider Board Therapy Compared With Exercise Only: A Randomized Controlled Trial of Patients Following Total Knee Arthroplasty
Authors: Beaupré Lauren A , Davies Donna M , Jones C Allyson , Cinats John G 
Published: February 2017

AbstractBackground and Purpose. The primary purpose of this randomized controlled trial was to determine which method of mobilization—(1) standardized exercises (SE) and continuous passive motion (CPM), (2) SE and slider board (SB) therapy, using an inexpensive, nontechnical device that requires minimal knee active range of motion (ROM), or (3) SE alone—achieved the maximum degree of knee ROM in the first 6 months following primary total knee arthroplasty (TKA). The secondary purpose was to compare health-related quality of life among these 3 groups. Subjects. The subjects were 120 patients (n=40/group) who received a TKA at a teaching hospital between June 1997 and July 1998 and who agreed to participate in the study. Methods. Subjects were examined preoperatively, at discharge, and at 3 and 6 months after surgery. The examination consisted of measurement of knee ROM and completion of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index and the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Results. The 3 treatment groups were similar with respect to age, sex, and diagnosis at the start of the study. There were no differences in knee ROM or in WOMAC Osteoarthritis Index or SF-36 scores at any of the measurement intervals. The rate of postoperative complications also was not different among the groups. Discussion and Conclusion. When postoperative rehabilitation regimens that focus on early mobilization of the patient are used, adjunct ROM therapies (CPM and SB) that are added to daily SE sessions are not required. Six months after TKA, patients attain a satisfactory level of knee ROM and function.
Balance and Mobility Following Stroke: Effects of Physical Therapy Interventions With and Without Biofeedback/Forceplate Training
Authors: Geiger Ruth Ann , Allen Jeffery B , O'Keefe Joanne , Hicks Ramona R 
Published: February 2017

Abstract
Background and Purpose. Visual biofeedback/forceplate systems are often used for treatment of balance disorders. In this study, the researchers investigated whether the addition of visual biofeedback/forceplate training could enhance the effects of other physical therapy interventions on balance and mobility following stroke. Subjects. The study included a sample of convenience of 13 outpatients with hemiplegia who ranged in age from 30 to 77 years (X̄=60.4, SD=15.4) and were 15 to 538 days poststroke. Methods. Subjects were assigned randomly to either an experimental group or a control group when the study began, and their cognitive and visual-perceptual skills were tested by a psychologist. Subjects were also assessed using the Berg Balance Scale and the Timed “Up & Go” Test before and after 4 weeks of physical therapy. Both groups received physical therapy interventions designed to improve balance and mobility 2 to 3 times per week. The experimental group trained on the NeuroCom Balance Master for 15 minutes of each 50-minute treatment session. The control group received other physical therapy for 50 minutes. Results. Following intervention, both groups scored higher on the Berg Balance Scale and required less time to perform the Timed “Up & Go” Test. These improvements corresponded to increased independence of balance and mobility in the study population. However, a comparison of mean changes revealed no differences between groups. Discussion and Conclusion. Although both groups demonstrated improvement following 4 weeks of physical therapy interventions, no additional effects were found in the group that received visual biofeedback/forceplate training combined with other physical therapy.

Published: February 2017

Abstract
Background and Purpose. Stretching protocols for elderly people (≥65 years of age) have not been studied to determine the effectiveness of increasing range of motion (ROM). The purpose of this study was to determine which of 3 durations of stretches would produce and maintain the greatest gains in knee extension ROM with the femur held at 90 degrees of hip flexion in a group of elderly individuals. Subjects. Sixty-two subjects (mean age=84.7 years, SD=5.6, range= 65–97) with tight hamstring muscles (defined as the inability to extend the knee to less than 20° of knee flexion) participated. Subjects were recruited from a retirement housing complex and were independent in activities of daily living. Methods. Subjects were randomly assigned to 1 of 4 groups and completed a physical activity questionnaire. The subjects in group 1 (n=13, mean age=85.1 years, SD=6.4, range=70–97), a control group, performed no stretching. The randomly selected right or left limb of subjects in group 2 (n=17, mean age=85.5 years, SD=4.5, range=80–93), group 3 (n=15, mean age=85.2 years, SD=6.5, range=65–92), and group 4 (n=17, mean age=83.2 years, SD=4.6, range=68–90) was stretched 5 times per week for 6 weeks for 15, 30, and 60 seconds, respectively. Range of motion was measured once a week for 10 weeks to determine the treatment and residual effects. Data were analyzed using a growth curve model. Results. A 60-second stretch produced a greater rate of gains in ROM (60-second stretch=2.4° per week, 30-second stretch=1.3° per week, 15-second stretch=0.6° per week), which persisted longer than the gains in any other group (group 4 still had 5.4° more ROM 4 weeks after treatment than at pretest as compared with 0.7° and 0.8° for groups 2 and 3, respectively). Discussion and Conclusion. Longer hold times during stretching of the hamstring muscles resulted in a greater rate of gains in ROM and a more sustained increase in ROM in elderly subjects. These results may differ from those of studies performed with younger populations because of age-related physiologic changes.
Patient Participation in Physical Therapy Goal Setting
Authors: Baker Susan M , Marshak Helen H , Rice Gail T , Zimmerman Grenith J 
Published: February 2017

Abstract
Background and Purpose. An important part of treatment planning in physical therapy is effective goal setting. The Guide to Physical Therapist Practice recommends that therapists should identify the patient's goals and objectives during the initial examination in order to maximize outcomes. The purpose of this study was to examine whether therapists seek to involve patients in goal setting and, if so, what methods they use. Therapists' attitudes toward participation and patient satisfaction with the examination were also examined. Subjects and Methods. Twenty-two physical therapists audiotaped the initial examination of 73 elderly patients (X̄=76.4 years of age, SD=7.1, range=65–94). The audiotaped examinations were then scored using the Participation Method Assessment Instrument (PMAI) to determine the frequency of attempts made by therapists to involve patients in goal setting. Therapists and patients completed surveys following the examinations. Results. Therapists' use of participation methods during examinations ranged from a minimum of 1 to a maximum of 19 out of 21 possible items on the PMAI. The therapists stated that they believed that it is important to include patients in goal-setting activities and that outcomes will be improved if patients participate. Patients also indicated that participation is important to them. Discussion and Conclusion. In most cases, the therapists did not fully take advantage of the potential for patient participation in goal setting. Patient and therapist education is needed regarding methods for patient participation during initial goal-setting activities.
Making Geriatric Assessment Work: Selecting Useful Measures
Authors: VanSwearingen Jessie M , Brach Jennifer S 
Published: February 2017

Abstract
Often the goal of physical therapy is to reduce morbidity and prevent or delay loss of independence. The purpose of this article is to describe issues to consider when selecting measures of physical function for use with community-dwelling adults over the age of 65 years. We chose 16 measures of physical function for review because they have been used in studies of community-dwelling older adults and some psychometric properties of reliability and validity have been described in the literature. Three major issues are discussed: (1) appropriateness of the measure for community-dwelling older adults, (2) practical aspects of test administration, and (3) psychometric properties. These issues are illustrated using examples from the 16 measures. Two scenarios, applying the measures to the assessment of physical performance of community-dwelling well older people and to the assessment of physical performance of community-dwelling frail older people, are used to illustrate how this information can be used.
A Review of Therapeutic Ultrasound: Effectiveness Studies
Authors: Robertson Valma J , Baker Kerry G 
Published: February 2017

AbstractBackground and Purpose. Therapeutic ultrasound is one of the most widely and frequently used electrophysical agents. Despite over 60 years of clinical use, the effectiveness of ultrasound for treating people with pain, musculoskeletal injuries, and soft tissue lesions remains questionable. This article presents a systematic review of randomized controlled trials (RCTs) in which ultrasound was used to treat people with those conditions. Each trial was designed to investigate the contributions of active and placebo ultrasound to the patient outcomes measured. Depending on the condition, ultrasound (active and placebo) was used alone or in conjunction with other interventions in a manner designed to identify its contribution and distinguish it from those of other interventions. Methods. Thirty-five English-language RCTs were published between 1975 and 1999. Each RCT identified was scrutinized for patient outcomes and methodological adequacy. Results. Ten of the 35 RCTs were judged to have acceptable methods using criteria based on those developed by Sackett et al. Of these RCTs, the results of 2 trials suggest that therapeutic ultrasound is more effective in treating some clinical problems (carpal tunnel syndrome and calcific tendinitis of the shoulder) than placebo ultrasound, and the results of 8 trials suggest that it is not. Discussion and Conclusion. There was little evidence that active therapeutic ultrasound is more effective than placebo ultrasound for treating people with pain or a range of musculoskeletal injuries or for promoting soft tissue healing. The few studies deemed to have adequate methods examined a wide range of patient problems. The dosages used in these studies varied considerably, often for no discernable reason.
Considerations for Planning and Conducting Clinic-Based Research in Physical Therapy
Authors: Fitzgerald G Kelley , Delitto Anthony 
Published: February 2017

Abstract
There is growing demand to increase the volume of clinic-based research in physical therapy. Special considerations, unique to the planning and conduct of clinic-based research, need to be addressed to increase the likelihood that these studies will be completed successfully. The purposes of this perspective are to discuss factors affecting clinic-based research and to offer suggestions for addressing these problems when designing and conducting research studies in a clinical setting. This perspective discusses issues such as patient management, determining the availability of target patient populations, acquiring support from physical therapists and physicians, reporting and managing research-related injury or illness, and modifying or terminating projects. Some of the points made in this perspective are illustrated using examples from the authors' experiences in conducting clinical research.
