The Effect of Walking Aids on Balance and Weight-Bearing Patterns of Patients With Hemiparesis in Various Stance Positions
Authors: Laufer Yocheved 
Published: February 2017

Abstract
Background and Purpose. Standard and quad canes are often prescribed to patients with hemiparesis, yet their effect on postural control remains unclear. Thus, the objective of this study was to examine the effects of standard and quad canes on postural sway and on weight-bearing patterns in patients with hemiparesis. Subjects. Thirty subjects with a diagnosis of unilateral hemiparesis following a stroke (patient group; mean age=71.2 years, SD=7.0) and 20 age-matched, community-dwelling volunteers without hemiparesis (comparison group; mean age=72.1 years, SD=5.2) participated in the study. Methods. Postural sway and percentage of body weight (%BW) borne by each extremity were measured in 3 positions: with the heels aligned with each other (aligned position) and in staggered foot positions with either the affected or unaffected extremity placed forward (affected FW and unaffected FW positions). All subjects were tested in each position with no cane, a standard cane, and a quad cane. The order of tests was randomized, and analysis of data included use of an analysis of variance and adjusted Tukey-Kramer tests. Results. In both the aligned and unaffected FW positions, postural sway was reduced only with the quad cane. Both types of canes reduced postural sway in the affected FW position; however, the quad cane had a greater effect. An asymmetrical weight distribution between the lower extremities did not change in the patient group across positions, even with walking aids. Discussion and Conclusion. A quad cane appears to be more effective than a standard cane in decreasing postural sway in patients with moderate impairment secondary to hemiparesis during stance. The greatest effect on postural sway occurred when the assistive device was contralateral to the foot placed forward. The use of a cane does not appear to adversely affect the asymmetrical weight-bearing pattern during stance that is characteristic of patients with hemiparesis, even when balance is challenged by decreasing the base of support.
An Investigation Into the Analgesic Effects of Interferential Currents and Transcutaneous Electrical Nerve Stimulation on Experimentally Induced Ischemic Pain in Otherwise Pain-Free Volunteers
Authors: Johnson Mark I , Tabasam Ghazala 
Published: February 2017

Abstract
Background and Purpose. Interferential currents (IFC) and transcutaneous electrical nerve stimulation (TENS) are used for pain management. This study compared the analgesic effects of IFC and TENS on experimentally induced ischemic pain in otherwise pain-free subjects using a modified version of the submaximal-effort tourniquet technique. Subjects. The subjects were 30 volunteers (18 male, 12 female) without known pathology that could cause pain. Their mean age was 33.5 years (SD=9.9, range=21–54). Method. A single-blind, sham-controlled, parallel-group method was used. The primary outcome measure was the change in the self-report of pain intensity during 1 of 3 possible interventions: (1) IFC, (2) TENS, or (3) sham electrotherapy. The IFC and TENS were administered on the forearm, and the sham electrotherapy group received no current output via a dummy stimulator. Results. A 2-way repeated-measures analysis of variance revealed that there was no change in pain intensity during treatment when all 3 groups were considered together. Further analysis revealed that IFC reduced pain intensity when compared with sham electrotherapy but not when compared only with TENS. Discussion and Conclusion. There were no differences in the magnitude of analgesia between IFC and TENS. Interferential currents reduced pain intensity to a greater extent than sham electrotherapy.
A Qualitative Study of Clinical Decision Making in Recommending Discharge Placement From the Acute Care Setting
Authors: Jette Diane U , Grover Lisa , Keck Carol P 
Published: February 2017

Abstract
Background and Purpose. One of the roles of rehabilitation professionals in the acute care setting is making recommendations for patients' discharge placement. The purpose of this investigation was to explore the decision-making process of physical therapists and occupational therapists when recommending discharge destination for patients following acute care hospitalization. Subjects. Participants were 7 physical therapists and 2 occupational therapists in an acute care rotation at a large academic medical center. Methods. A grounded-theory strategy was used. Three interviews were conducted and guided by questions about participants' approaches to discharge decision making. Information from the interview transcripts was used to define constructs. A model was generated to explain the relationships among the constructs. Results. Decision making regarding discharge recommendations was guided by 4 constructs: patients' functioning and disability, patients' wants and needs, patients' ability to participate in care, and patients' life context. Information was filtered through therapists' experiences and modified by the health care team's opinions and by health care regulations. Discussion and Conclusion. The decision making of the rehabilitation professionals studied in recommending discharge placements for their patients reflects consideration of patients as individuals and the environments in which they live. Information about patients is filtered through the experience of therapists and influenced by health care regulations and opinions of other health care professionals, the patients, and their associates. The findings might be used in teaching clinical decision making to clinicians and students as they learn to make discharge recommendations.
A Physiological Profile Approach to Falls Risk Assessment and Prevention
Authors: Lord Stephen R , Menz Hylton B , Tiedemann Anne 
Published: February 2017

Abstract
The purpose of this perspective article is to describe the use of a physiological profile approach to falls risk assessment and prevention that has been developed by the Falls and Balance Research Group of the Prince of Wales Medical Research Institute, Sydney, Australia. The profile's use for people with a variety of factors that put them at risk for falls is discussed. The Physiological Profile Assessment (PPA) involves a series of simple tests of vision, peripheral sensation, muscle force, reaction time, and postural sway. The tests can be administered quickly, and all equipment needed is portable. The results can be used to differentiate people who are at risk for falls (“fallers”) from people who are not at risk for falls (“nonfallers”). A computer program using data from the PPA can be used to assess an individual's performance in relation to a normative database so that deficits can be targeted for intervention. The PPA provides valid and reliable measurements that can be used for assessing falls risk and evaluating the effectiveness of interventions and is suitable for use in a range of physical therapy and health care settings.
Use of Power Mobility for a Young Child With Spinal Muscular Atrophy
Authors: Jones Maria A , McEwen Irene R , Hansen Laura 
Published: February 2017

Abstract
Background and Purpose. Young children with severe motor impairments, such as spinal muscular atrophy, are often unable to move around their environment independently; therefore, they may be at risk for delays in areas of development not directly related to their motor limitations. Power mobility is an intervention that provides young children a means of independent movement and enables them to independently explore their environment. Case Description. The participant was a 20-month-old girl with type II spinal muscular atrophy. Intervention. The authors provided the child with a power wheelchair and gave her mother and physical therapist general guidelines to encourage her use of the power wheelchair. Outcomes. Within 6 weeks after receiving the power wheelchair, the child operated the wheelchair independently. She showed developmental gains in all domains of the Battelle Developmental Inventory and the Pediatric Evaluation of Disability Inventory over 6 months. The authors conducted an interview with the child's mother before and after intervention. She reported that the child was more independent after receiving the power wheelchair. Discussion. The power wheelchair may have been associated with the changes in the child's mobility and her developmental changes over 6 months.

Published: February 2017

Abstract
Background and Purpose. Few tests have been found to be strongly predictive of falls in community-dwelling older adults. The purpose of this study was to determine whether data from 5 balance tests—combined with data regarding fall history, number of medications, dizziness, visual problems, use of an assistive device, physical activity level, sex, and age—could predict falls in community-dwelling older adults who were independent. Subjects. Ninety-nine community-dwelling older adults aged 65 to 90 years (X̄= 74.02, SD=5.64) were tested. Methods. Subjects were tracked for falls over a 1-year period following testing. Impairment-based tests, which are tests that attempt to specifically identify which sensory systems are impaired or how motor control is impaired (eg, speed, accuracy of movement), were the Modified Clinical Tests of Sensory Interaction for Balance (Modified CTSIB) and the 100% Limits of Stability Test, both of which were done on the Balance Master 6.1. Performance-based tests, which are functional tests that identify functional limitations without necessarily identifying their causes, were the Berg Balance Scale, the Timed “Up & Go” Test, and the Dynamic Gait Index. Demographic and health data included age, sex, number of medications, physical activity level, presence of dizziness, vision problems, and history of falls over the previous year. Logistic regression was used to determine which combinations of data from balance tests, demographics, and health factors were predictive of falls. Results. Two models—(1) the “standing on a firm surface with eyes closed” (FEC) condition of the Modified CTSIB and (2) the FEC combined with age and sex—were predictive of falls, but predicted only 1 and 2 subjects who were at risk for falling, respectively, out of 20 people who were at risk for falling. Discussion and Conclusion. Five balance tests combined with health and demographic factors did not predict falls in a sample of community-dwelling older adults who were active and independent.

Authors: Schachter Candice L , Busch Angela J , Peloso Paul M , Sheppard M Suzanne 
Published: February 2017

Abstract
Background and Purpose. The purposes of this study were: (1) to assess the effectiveness of a 16-week progressive program of home-based, videotape-based, low-impact aerobic exercise on physical function and signs and symptoms of fibromyalgia in previously sedentary women aged 20 to 55 years and (2) to compare the effects of 1 long exercise bout versus 2 short exercise bouts per training day (fractionation) on physical function, signs and symptoms of fibromyalgia, and exercise adherence. Subjects. One hundred forty-three sedentary women were randomly assigned to 1 of 3 groups: a group who trained using a long bout of exercise (LBE group, n=51), a group who trained using short bouts of exercise (SBE group, n=56), and a group who performed no exercise (NE group, n=36). Methods. The SBE group exercised twice daily, and the LBE group worked out once daily. Both groups progressed in total daily training duration from 10 to 30 minutes, 3 to 5 times a week, for 16 weeks. Physical and psychological well-being, symptoms, and self-efficacy were evaluated using a multivariate analysis of variance. Results. Dropout rates for the NE, SBE, and LBE groups were 14%, 38%, and 29%, respectively. The NE group differed from the LBE group in disease severity, self-efficacy, and psychological well-being (midtest, efficacy analysis) and from the SBE group in disease severity and self-efficacy (posttest, efficacy analysis). Exercise adherence was greater for the LBE group than for the SBE group between weeks 5 and 8 of the training program. No other differences between exercise groups were found. Discussion and Conclusion. Progressive, home-based, low-impact aerobics improved physical function and fibromyalgia symptoms minimally in participants who completed at least two thirds of the recommended exercise. Fractionation of exercise training provided no advantage in terms of exercise adherence, improvements in fibromyalgia symptoms or physical function. High attrition rates and problems with exercise adherence were experienced in both exercise groups.
Application of Constraint-Induced Movement Therapy for an Individual With Severe Chronic Upper-Extremity Hemiplegia
Authors: Bonifer Nancy (McNamara) , Anderson Kristin M 
Published: February 2017

Abstract
Background and Purpose. Constraint-induced movement therapy (CIMT) has been documented to improve motor function in the upper extremity of people with mild hemiparesis. The use of CIMT has not been documented for people with severe hemiparesis. This case report describes a CIMT program for an individual with severe upper-extremity deficits as a result of stroke. Case Description. The client was a 53-year-old woman who had a stroke 15 years previously and had no isolated movement in her right upper extremity. Methods. The client completed a 3-week CIMT program during which she restrained her left upper extremity and participated in intensive training of her right upper extremity. Task practice and shaping were the primary techniques used for training. Outcomes. Increased scores were noted from pretreatment to posttreatment on the Motor Activity Log, Graded Wolf Motor Function Test (GWMFT), and Fugl-Meyer Evaluation of Physical Performance. Further progress on the GWMFT was noted at the 6-month follow-up. Fugl-Meyer test scores remained higher than at pretreatment, but Motor Activity Log scores returned to near baseline by the 6-month follow-up. The speed of performance on the GWFMT did not change. Although some scores increased, the client reported and demonstrated no progress in functional use of the involved upper extremity at the end of the program. Discussion. This case report describes the use of CIMT with an individual who had severe chronic motor deficits as a result of stroke. Further investigation of CIMT, as well as investigation of CIMT in combination with other motor recovery interventions, is warranted.
Comparison of the Oxygen Cost of Breathing Exercises and Spontaneous Breathing in Patients With Stable Chronic Obstructive Pulmonary Disease
Authors: Jones Alice YM , Dean Elizabeth , Chow Cedric CS 
Published: February 2017

AbstractBackground and Purpose. The oxygen demand of breathing exercises and the clinical implications have not been studied in detail. In this study, the oxygen cost of 3 common breathing exercises believed to reduce oxygen cost (ie, work of breathing) was compared with that of spontaneous breathing in patients with chronic obstructive pulmonary disease (COPD). Subjects. Thirty subjects with stable, moderately severe COPD participated. Methods. Oxygen consumption (V̇o2) and respiratory rate (RR) during spontaneous breathing at rest (SB) were recorded for 10 minutes. Subjects then performed 3 breathing exercises in random order, with a rest between exercises: diaphragmatic breathing (DB), pursed-lip breathing (PLB), and a combination of DB and PLB (CB). Oxygen consumption and RR were measured. Results. Mean V̇o2 (±SD) was lower during the breathing exercises (165.8±22.3 mL O2/min for DB, 164.8±20.9 mL O2/min for PLB, and 167.7±20.7 mL O2/min for CB) compared with SB (174.5±25.2 mL O2/min). Correspondingly, mean RR (±SD) was higher during SB (17.3±4.23 breaths/min), followed by DB (15.0±4.32 breaths/min), PLB (12.8±3.53 breaths/min), and CB (11.2±2.7 breaths/min). Discussion and Conclusion. Given that patients do not spontaneously adopt the breathing pattern with the least V̇o2 and the lowest RR, the results suggest that determinants of the breathing pattern other than metabolic demand warrant being a primary focus in patients with COPD.
Medial Pontine Hemorrhagic Stroke
Authors: Ruhland Janet L , van Kan Peter LE 
Published: February 2017

Abstract
Background and Purpose. This case report documents a rare opportunity to observe the motor function of an individual for nearly 6 months following a primary pontine hemorrhage in the medial pontine tegmentum of the brain stem. The purpose of this report is to illustrate how knowledge of the location of the hemorrhage, in conjunction with knowledge of brain-stem structure-function relationships, informs physical therapist examination and intervention. Case Description. RM, a right-handed 81-year-old man with hypertension, had a hemorrhagic brain-stem stroke that severely compromised control of posture and whole-limb movements. Some residual ability to use the right hand and fingers remained, provided the trunk and right upper arm were stabilized. RM had undiminished intellectual abilities and unaltered memory because of sparing of cerebral cortices. RM's cognitive abilities, however, were obscured by severe impairments in interpersonal communication because of extensive damage to cranial nerve structures. Computed tomographic scans verified that the hematoma crossed the midline and was confined to the medial pontine tegmentum. Discussion. We interpret motor deficits resulting from stoke in the medial pontine tegmentum in terms of damage to brain-stem descending motor systems and ascending somatosensory systems. Recognition of cognitive and residual motor abilities following brain-stem stroke can aid in the development of rehabilitation strategies.

Published: February 2017

Abstract
Background and Purpose. Lateral epicondylitis (“tennis elbow”) is a common entity. Several nonoperative interventions, with varying success rates, have been described. The aim of this study was to compare the effectiveness of 2 protocols for the management of lateral epicondylitis: (1) manipulation of the wrist and (2) ultrasound, friction massage, and muscle stretching and strengthening exercises. Subjects and Methods. Thirty-one subjects with a history and examination results consistent with lateral epicondylitis participated in the study. The subjects were randomly assigned to either a group that received manipulation of the wrist (group 1) or a group that received ultrasound, friction massage, and muscle stretching and strengthening exercises (group 2). Three subjects were lost to follow-up, leaving 28 subjects for analysis. Follow-up was at 3 and 6 weeks. The primary outcome measure was a global measure of improvement, as assessed on a 6-point scale. Analysis was performed using independent t tests, Mann-Whitney U tests, and Fisher exact tests. Results. Differences were found for 2 outcome measures: success rate at 3 weeks and decrease in pain at 6 weeks. Both findings indicated manipulation was more effective than the other protocol. After 3 weeks of intervention, the success rate in group 1 was 62%, as compared with 20% in group 2. After 6 weeks of intervention, improvement in pain as measured on an 11-point numeric scale was 5.2 (SD=2.4) in group 1, as compared with 3.2 (SD=2.1) in group 2. Discussion and Conclusion. Manipulation of the wrist appeared to be more effective than ultrasound, friction massage, and muscle stretching and strengthening exercises for the management of lateral epicondylitis when there was a short-term follow-up. However, replication of our results is needed in a large-scale randomized clinical trial with a control group and a longer-term follow-up.

Published: February 2017

AbstractBackground and Purpose. Decreasing hospital stays for patients with total knee arthroplasties (TKAs) have a direct effect on rehabilitation. The identification of modifiable determinants of postsurgical functional status would help physical therapists plan for discharge from hospitals. The purpose of this study was to identify preoperative determinants of functional status after a TKA. Participants. Using a community-based, prospective cohort study, data were collected from 276 patients who received a primary TKA in a Canadian health care region. Data were collected in the month before surgery and 6 months after surgery. Methods. Function was measured using the function subscale of a disease-specific measure—the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index—and a generic health status measure—the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). Independent variables examined included demographic variables (eg, age, sex), medical variables (eg, diagnosis, number of comorbid conditions, ambulatory status), surgical variables (eg, type of implant, number of complications), and knee range of motion. Results. At 6 months after surgery, the average WOMAC physical function score was 70.5 (SD=18.2) and the average SF-36 physical function score was 44.8 (SD=25.3). Using multiple regression analyses, baseline function, walking device, walking distance, and comorbid conditions predicted 6-month function (WOMAC: R2=.20; SF-36 physical function: R2=.27). Discussion and Conclusion. Patients who have lower preoperative function may require more intensive physical therapy intervention because they are less likely to achieve functional outcomes similar to those of patients who have less preoperative dysfunction.
Phonophoresis Versus Topical Application of Ketoprofen: Comparison Between Tissue and Plasma Levels
Authors: Cagnie Barbara , Vinck Elke , Rimbaut Steven , Vanderstraeten Guy 
Published: February 2017

Abstract
Background and Purpose. Over the last few decades, application of ultrasound has been attempted to enhance transdermal transport of several drugs, a method referred to as “phonophoresis.” The purposes of this study were to examine the influence of ultrasound on the transdermal delivery of ketoprofen in humans and to compare the concentrations found after continuous and pulsed application. Subjects and Methods. Twenty-six patients with knee disorders requiring arthroscopy were randomly assigned to 1 of 3 groups. Just before surgery, phonophoresis of a ketoprofen gel (Fastum gel) was given to group A using continuous ultrasound (1 MHz, 1.5 W/cm2, for 5 minutes). Group B received the same treatment but with pulsed ultrasound (100 Hz, 20% duty cycle). Group C received 5 minutes of sham ultrasound with the ketoprofen gel. The ultrasound head was moved over a 10-cm2 area using small, continuous, circular movements. Biopsies of adipose tissue and synovial tissue were taken during surgery to evaluate the local penetration of the drug. Blood samples also were collected to determine whether ketoprofen entered the systemic circulation. Results. The concentration of ketoprofen in plasma was negligible in all 3 groups. The concentration of ketoprofen in synovial tissue differed from that in fat tissue. A difference in concentration of ketoprofen in synovial tissue was found between group C and groups A and B. The concentration of ketoprofen in fat tissue and synovial tissue was consistently higher in group B than in group A. Discussion and Conclusion. This study confirms that phonophoresis of ketoprofen allows the attainment of higher local concentrations, whereas systemic exposure is lower. The results indicate that, in contrast to sham phonopheresis, ultrasound can increase the transdermal delivery of ketoprofen.
