Authors: Ropponen Annina , Levälahti Esko , Videman Tapio , Kaprio Jaakko , Battié Michele C
Published: February 2017

Background and Purpose. Our understanding of what different back performance tests are measuring is limited. The purpose of this study was to investigate the relative contributions of genetics and unique and common environmental factors for 3 tests of back muscle performance in a classic twin analysis. Subjects. The subjects were a population-based sample of 122 monozygotic and 131 dizygotic male twin pairs aged 35 to 69 years (X̄=49.9, SD=7.7). Methods. Variance component analysis was applied to estimate genetic and environmental influences on isokinetic and psychophysical lifting and isometric trunk extensor endurance test performance. The Cholesky decomposition genetic factor model was used to estimate genetic and environmental correlations of these variables. Path analysis was applied to study determinants of isokinetic and psychophysical lifting and isometric trunk extensor endurance test performance. Results. Genetic effects accounted for 60%, 33%, and 5% of the total variance of isokinetic and psychophysical lifting forces and isometric trunk extensor endurance, respectively, and unique environmental factors accounted for 35%, 49%, and 61% of the variance. Discussion and Conclusion. Genetics had a dominant role in isokinetic lifting and unique environmental factors in isometric trunk extensor endurance. The relatively high role of genetics in lifting force suggests the potential to increase and sustain changes in back muscle force in the general population may be particularly challenging.
The Use of Electrical Stimulation and Taping to Address Shoulder Subluxation for a Patient With Central Cord Syndrome
Authors: Peterson Colleen
Published: February 2017

Background and Purpose. This case report describes the examination, intervention, and outcome of a patient with central cord syndrome (CCS) who participated in acute rehabilitation that included the use of electrical stimulation (ES) and strapping to address shoulder subluxation. The only literature found describing these interventions for shoulder subluxation was for patients with stroke. Case Description. The patient was a 29-year-old man with CCS and bilateral shoulder subluxation. He received ES over 8 weeks to the anterior and middle deltoid and supraspinatus muscles of the right shoulder. Taping was repeated every 3 to 4 days on both shoulders following over the anterior and middle deltoid muscles up to the acromion. Outcomes. The initial shoulder subluxation measurements were 1.5 cm on the right and 1.0 cm on the left. The final measurements were 0.3 cm on the right and 0.2 cm on the left. The patient's American Spinal Injury Association upper-extremity motor scores were 26/50 initially and 48/50 at discharge. Conclusion. The use of ES and shoulder taping in conjunction with other rehabilitation may have played a role in reducing the patient's shoulder subluxation.

Authors: McClure Philip W , Bialker Jason , Neff Nancy , Williams Gerald , Karduna Andrew
Published: February 2017

Background and Purpose. Shoulder impingement syndrome is a common condition and is often managed with an exercise program. The purpose of this study was to examine an exercise program in patients with shoulder impingement syndrome. Specifically, the purpose was to identify changes that might occur in 3-dimensional scapular kinematics, physical impairments, and functional limitations. Subjects. Fifty-nine patients with impingement syndrome were recruited, and 39 patients successfully completed the 6-week rehabilitation program and follow-up testing. Impingement was defined as having at least 3 of 6 predefined clinical signs or symptoms. Methods. Subjects were assessed before and after a 6-week rehabilitation program and again at 6 months. Pain, satisfaction, and function were measured using the University of Pennsylvania Shoulder Scale. Range of motion, isometric muscle force, and 3-dimensional scapular kinematic data also were collected. Subjects were given a progressive exercise program that included resistive strengthening, stretching, and postural exercises that were done daily at home. Subjects also were given shoulder education related to anatomy, the basic mechanics of impingement, and strategies for reducing load on the shoulder. Each subject attended one physical therapy session per week for a 6-week period, primarily for monitoring and upgrading the exercise program. Pretest and posttest scores were compared using paired t tests and repeated-measures analysis of variance. Results. Passive range of motion increased for both external and internal rotation but not for elevation. Abduction external and internal rotation force all increased. There were no differences in scapular kinematics. Improvements were found for pain, satisfaction, and shoulder function and for Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) scores related to physical function. At 6-month follow-up, improvements made in pain, satisfaction, and function were maintained. Discussion and Conclusion. The use of this exercise protocol in the management of shoulder impingement syndrome may have a positive impact on patients' impairments and functional limitations. Our findings suggest a relatively simple exercise program combined with patient education may be effective and, therefore, merits study in a larger trial using a control group. Changes in scapular kinematics did not appear to be a primary mechanism underlying improvement in symptoms and function.
Effect of Achilles Tendon Lengthening on Ankle Muscle Performance in People With Diabetes Mellitus and a Neuropathic Plantar Ulcer
Authors: Salsich Gretchen B , Mueller Michael J , Hastings Mary Kent , Sinacore David R , Strube Michael J , Johnson Jeffrey E
Published: February 2017

Background and Purpose. The effect of a tendo-Achilles lengthening (TAL) procedure on ankle muscle performance has not been clearly established. The purpose of this study was to compare the effects of TAL and total-contact casting (TCC) with TCC alone on ankle muscle performance in subjects with diabetes mellitus (DM) and a neuropathic plantar ulcer. Subjects. Subjects were randomly assigned to either a TAL group (3 female and 12 male subjects) or a TCC group (4 female and 10 male subjects). Methods. Muscle performance measurements were obtained using an isokinetic dynamometer. Results. Concentric plantar-flexor peak torque decreased 31% after TAL but returned to the baseline level after 8 months. Dorsiflexor peak torque did not change in either group. Plantar-flexor passive torque at 0 degrees of dorsiflexion decreased after TAL but increased to 60% of the baseline level after 8 months. Maximal dorsiflexion angle increased 11 degrees after TAL and remained increased at 8 months. Discussion and Conclusion. The TAL resulted in an increase in ankle dorsiflexion range of motion and a temporary reduction in concentric plantar-flexor peak torque and passive torque at 0 degrees of dorsiflexion. If TAL is being considered for people with DM and a neuropathic forefoot ulcer, the initial compromise in plantar-flexor muscle performance should be addressed.

Published: February 2017

Background and Purpose. Cognitive deficits after stroke are common and interfere with recovery. One purpose of this study was to determine whether the motor abilities of subjects who have poststroke cognitive deficits and who have received problem-oriented willed-movement (POWM) therapy will improve more than the motor abilities of subjects in the reference group who have received neurodevelopmental treatment (NDT). Another purpose of this study was to identify the relationship between cognitive function and motor abilities for both groups. Subjects. The subjects recruited for this study were 36 men and 11 women with various degrees of poststroke cognitive deficits. Methods. A randomized block design was used to assign the subjects to 2 groups. Cognitive function and motor ability were evaluated with the Mini-Mental State Examination and the Stroke Rehabilitation Assessment of Movement (STREAM). Both groups received physical therapy 5 or 6 times per week in 50-minute sessions. Results. The STREAM scores improved after treatment in both groups. Main group effects were found for the lower-extremity (F=4.58, P<.05) and basic mobility (F=27.49, P<.01) subscales of the STREAM. Pretest cognitive function showed a positive relationship with posttest motor ability in the NDT group (r=.446, P<.05). However, the relationship between pretest cognitive function and posttest motor ability had no statistical significance in the POWM group (r=.101, P=.630). Discussion and Conclusion. These findings suggest that, regardless of a person's cognitive function, POWM intervention is effective in improving lower-extremity and basic mobilities and indicates the need to use relatively intact cognitive function or perceptual function, or both, to improve motor rehabilitation for people with cognitive function deficits.
Individually Tailored Treatment Targeting Motor Behavior, Cognition, and Disability: 2 Experimental Single-Case Studies of Patients With Recurrent and Persistent Musculoskeletal Pain in Primary Health Care
Authors: Åsenlöf Pernilla , Denison Eva , Lindberg Per
Published: February 2017

Background and Purpose. This article introduces an individually tailored intervention targeting motor behavior, cognition, and disability in patients managed by physical therapists in primary health care. Effects on self-rated disability, pain intensity, and pain control are described. Subjects. Two women with recurrent or persistent disabling musculoskeletal pain were selected. Methods. Two experimental single-subject A1-B-C-A2 studies with multiple baselines across situations were used. Principal outcome data were collected daily with patient-specific continuous measures for 3 weeks before intervention, continuously during intervention, and for 2 weeks during each of the 1-, 4-, 6-, and 12-month follow-up examinations. Results. Disability and pain intensity decreased, and pain control increased in both subjects. The results were maintained at the follow-up examinations. Discussion and Conclusion. Positive outcomes of the intervention were reported from 2 subjects with recurrent and persistent disabling pain. Procedures for systematic tailoring of treatment to behavioral goals and individual patient characteristics are available as a result of the successful application. The results need to be replicated in future clinical controlled group studies.

Authors: Jan Mei-Hwa , Chai Huei-Ming , Lin Yeong-Fwu , Lin Janice Chien-Ho , Tsai Li-Ying , Ou Yu-Chih , Lin Da-Hon
Published: February 2017

Background and Purpose. The ability to perform 20 or more one-leg heel-rises is considered a “normal” grade for muscle strength (force-generating capacity of muscle) of the ankle plantar flexors, regardless of age and sex. Because muscle strength is closely related to age and sex, the “normal” test criterion was re-evaluated in different groups categorized by age and sex. Subjects and Methods. One hundred eighty sedentary volunteers (21–80 years of age) without lower-limb lesions performed as many repetitions of one-leg heel-rise as possible. Lunsford and Perry criteria were used to determine completion of the test. Results. The age and sex of the participants influenced the maximal repetitions of heel-rise, and the repetitions decreased with age and in female subjects. Discussion and Conclusion. The muscle strength of the ankle plantar flexors, as measured by manual muscle testing, varied with age and sex. Clinicians should consider the variances of age and sex when they perform manual muscle testing of the ankle plantar flexors.
The EdUReP Model for Nonsurgical Management of Tendinopathy
Authors: Davenport Todd E , Kulig Kornelia , Matharu Yogi , Blanco Cesar E
Published: February 2017

Tendinopathy is a common and substantial source of morbidity worldwide. Various anatomical and functional predispositions combine with abrupt changes in mechanical loading to cause characteristic histological maladaptations in tendons. The nature and latency of cellular changes in tendinopathy makes many common treatments lessthan-optimal options. This Perspective presents the EdUReP model for nonsurgical management of tendinopathy, a model that considers sources of pathology at the cellular, anatomical, and functional levels. The EdUReP model addresses possible sources of symptoms at the levels of pathology, impairment, functional limitation, and disability through Educational interventions, periods of tendon Unloading and controlled Reloading, and implementation of Prevention strategies. The EdUReP model is an evidence-based treatment construct that aims to reduce functional limitation and disability through amelioration of tissue pathology.
Interventions That Increase or Decrease the Likelihood of a Meaningful Improvement in Physical Health in Patients With Sciatica
Authors: Jewell Dianne V , Riddle Daniel L
Published: February 2017

Background and Purpose. The purpose of our study was to determine whether physical therapy interventions predicted meaningful short-term improvement in physical health for patients diagnosed with sciatica. Subjects. We examined data from 1,804 patients (age: X̄=52.1 years, SD=15.6 years; 65.7% female, 34.3% male) who had been diagnosed with sciatica and who had completed an episode of outpatient physical therapy. Methods. Principal components factor analysis was used to define intervention categories from specific treatments applied during the plan of care. A nested-model logistic regression analysis identified intervention categories that predicted meaningful improvement in physical health. Meaningful improvement was defined as a change of 14 or more points on the Physical Component Scale-12 (PCS-12) summary score. Results. Twenty-six percent (n=473) of patients had a meaningful improvement in physical health. Improvement was more likely in patients receiving joint mobility interventions (odds ratio [OR]=2.5, 95% confidence interval [CI]=1.5–4.4) or general exercise (OR=1.5, 95% CI=1.2–2.0). Patients who received spasm reduction interventions were less likely to improve (OR=0.77, 95% CI=0.60–0.98). Discussion and Conclusion. Physical therapists should emphasize the use of joint mobility interventions and exercise when treating patients with sciatica, whereas interventions for spasm reduction should be avoided.
Physical Therapists’ Use of Interventions With High Evidence of Effectiveness in the Management of a Hypothetical Typical Patient With Acute Low Back Pain
Authors: Mikhail Christine , Korner-Bitensky Nicol , Rossignol Michel , Dumas Jean-Pierre
Published: February 2017

Background and Purpose. Evidence-based practice aims to improve patient care and service delivery, particularly in the management of individuals with low back pain (LBP), the largest client group seen by outpatient physical therapists. The purpose of this study was to determine the prevalence of use of interventions with evidence of effectiveness in the management of acute nonspecific LBP by physical therapists. Subjects. A multicenter cross-sectional study was conducted on 100 physical therapists working with patients with LBP. Methods. Using a telephone-administered interview, therapists described their current and desired treatment practices for a typical case of LBP. Each intervention reported was coded according to its evidence of effectiveness (strong, moderate, limited, or none). Information on clinician, workplace, and client characteristics also was obtained. Results. The prevalence of use of interventions with strong or moderate evidence of effectiveness was 68%. However, 90% to 96% of therapists also used interventions for which research evidence was limited or absent. Users of interventions with high evidence of effectiveness, as compared with nonusers, had graduated more recently and had taken a higher number of postgraduate clinical courses. Discussion and Conclusion. Although most therapists use interventions with high evidence of effectiveness, much of their patient time is spent on interventions that are not well reported in the literature. The results indicate the need for improvement in the quality of clinical research as well as its dissemination and implementation in a way that is appealing to therapists, such as through practice-related courses.

Authors: Depledge Jill , McNair Peter J , Keal-Smith Cheryl , Williams Maynard
Published: February 2017

Background and Purpose. Symphysis pubis pain is a significant problem for some pregnant women. The purpose of this study was to investigate the effects of exercise, advice, and pelvic support belts on the management of symphysis pubis dysfunction during pregnancy. Subjects. Ninety pregnant women with symphysis pubis dysfunction were randomly assigned to 3 treatment groups. Methods. A randomized masked prospective experimental clinical trial was conducted. Specific muscle strengthening exercises and advice concerning appropriate methods for performing activities of daily living were given to the 3 groups, and 2 of the groups were given either a rigid pelvic support belt or a nonrigid pelvic support belt. The dependent variables, which were measured before and after the intervention, were a Roland-Morris Questionnaire score, a Patient-Specific Functional Scale score, and a pain score (101-point numerical rating score). Results. After the intervention, there was a significant reduction in the Roland-Morris Questionnaire score, the Patient-Specific Functional Scale score, and the average and worst pain scores in all groups. With the exception of average pain, there were no significant differences between groups for the other measures. Discussion and Conclusion. The findings indicate that the use of either a rigid or a nonrigid pelvic support belt did not add to the effects provided by exercise and advice.

Published: February 2017

Background and Purpose Manual therapy and exercise have not previously been compared with a home exercise program for patients with osteo-arthritis (OA) of the knee. The purpose of this study was tocompare outcomes between a home-based physical therapy program and a clinically based physical therapy program. Subjects. One hundred thirty-four subjects with OA of the knee were randomly assigned to a clinictreatment group (n=66; 61% female, 39% male; mean age [±SD]=64±10 years) or a home exercise group (n=68, 71% female, 29% male; mean age [±SD]=62±9 years). Methods. Subjects in the clinic treatment group received supervised exercise, individualized manual therapy, and a home exercise program over a 4-week period. Subjects in the home exercise group received thesame home exercise program initially, reinforced at a clinic visit 2 weeks later. Measured outcomes were the distance walked in 6 minutes and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Results. Both groups showed clinically and statistically significant improvements in 6-minute walkdistances and WOMAC scores at 4 weeks; improvements were still evident in both groups at 8 weeks. By 4 weeks, WOMAC scores had improved by 52% in the clinic treatment group and by 26% in the home exercise group. Average 6-minute walk distances had improved about 10% in both groups. At 1 year, both groups were substantially and about equally improved over baseline measurements. Subjects in the clinic treatment group were less likely to betaking medications for their arthritis and were more satisfied with the overall outcome of their rehabilitative treatment compared with subjects in the home exercise group. Discussion and Conclusion Although both groups improved by 1 month, subjects in the clinic treatment group achieved about twice as much improvement in WOMAC scores than subjects who performed similar unsupervised exercises at home. Equivalent maintenance of improvements at 1 year was presumably due to both groups continuing the identical home exercise program. The results indicate that a home exercise program for patients with OA of the knee provides important benefit. Adding a small number of additional clinical visits for the application of manual therapy and supervised exercise adds greater symptomatic relief.

Authors: Lyle Mark A , Manes Sarah , McGuinness Michael , Ziaei Sarah , Iversen Maura D
Published: February 2017

Background and Purpose. Limited data are available to assist clinicians in clinical decision making. The purpose of this study was to examine the relationships of symptom provocation during physical examination (PE) procedures and self-report of symptom severity and function in patients with degenerative lumbar conditions. Subjects. Twenty-four men and 50 women with chronic low back pain (CLBP) (>6 months duration) were recruited from a university hospital (median age=64.2 years, X̄=66.8, SD=12.4, range=55.7–97.8). Methods. Demographic information, medical history, PE findings, and data from 2 self-report measures of symptom severity and function (Lumbar Spinal Stenosis [LSS] questionnaire and Medical Outcomes Study 36-Item Short-Form Health Survey [SF-36]) were collected. Results. Patients had moderate symptoms of degenerative lumbar conditions (mean LSS symptom score=2.67, SD=0.71) and reported some difficulties with low back function (mean LSS function score=1.99, SD=0.61). The most frequent physical examination findings were a positive quadrant test (70%), followed by lower-extremity muscle weakness (64%), abnormal reflexes (62%), and active lumbar extension (61%). Patients who were symptomatic during the quadrant test, patients who had pain with lateral flexion, and patients who had lower-extremity weakness had higher self-reported LSS symptom severity (t=−3.06, P=.003; t=−2.96, P=.004; and t=−3.2, P=.002, respectively). Pain with lumbar extension was moderately correlated with LSS symptom severity (Spearman rho=.31, P=.007). No lumbar PE procedure was associated with decreased condition-specific function. The quadrant test was the strongest predictor of symptom severity (β=.54, r2=.21, P=.0009). Discussion and Conclusion. The association between PE findings and self-reported symptom severity in this sample is consistent with the pathoanatomy of degenerative spinal conditions and indicates that movement that narrows the foraminal space contributes to symptom severity. The quadrant test distinguished those subjects with clinically meaningful low back symptom severity but was not predictive of impaired function. This study illustrates the potential benefit of identifying clinical PE measures that are reflective of condition severity and back-specific function in patients with similar clinical syndromes.
The Association Between Medication Usage and Dropout Status Among Participants of an Exercise Study for People With Osteoarthritis
Authors: Wilder Frances V , Barrett John P
Published: February 2017

Background and Purpose. Little is known about predictors of dropout status in exercise studies for people with osteoarthritis. Losses to follow-up can pose serious threats to study validity. The purpose of this study was to assess the ability of arthritis medication usage the month prior to enrollment to predict dropout status among participants in an exercise study for people with osteoarthritis. Subjects and Methods. Men and women who participated in an exercise study for people with osteoarthritis (N=143) were followed. Participants who completed 24+ months of the exercise program were considered retained, whereas individuals who withdrew prior to 24 months were considered dropouts. Results. Of the 143 participants analyzed, 78 (55%) completed 24+ months of the exercise program and 65 (45%) dropped out. Among those who reported arthritis medication usage, 54% were lost to follow-up. The group reporting no usage of arthritis medication had a 20% dropout rate (odds ratio=3.5, 95% confidence interval=1.6–7.6). The final adjusted model controlling for baseline health status, body mass index, and the interaction between baseline health status and body mass index indicated that those individuals who reported arthritis medication usage were more than 4 times more likely to drop out than were those who reported no arthritis medication usage (odds ratio=4.5, 95% confidence interval=1.8–11.4). Discussion and Conclusion. The results showed that self-reported arthritis medication usage the month prior to study enrollment was associated with subsequent dropout status among this group of exercisers with osteoarthritis. Further identification of baseline characteristics predictive of participant dropout status may benefit future exercise studies. A priori knowledge of “at-risk” exercise study participants will afford the opportunity for the timely allocation of appropriate resources aimed at reducing losses to follow-up.
Clinical Examination Variables Discriminate Among Treatment-Based Classification Groups: A Study of Construct Validity in Patients With Acute Low Back Pain
Authors: George Steven Z , Delitto Anthony
Published: February 2017

Background and Purpose. Treatment-based classification (TBC) provides matched interventions for patients with acute low back pain (LBP) through key history and clinical findings. This study investigated the discriminant validity of TBC by determining whether commonly used clinical examination variables discriminated among TBC groups. Subjects. The mean age of the 131 participants was 37.7 years (SD=10.1), 66 participants (50.4%) were female, mean duration of LBP was 16.5 days (SD=16.1), and 60 participants (45.8%) had a prior history of LBP. Fifty-one study participants (38.9%) were classified for specific exercise, 42 (32.1%) for mobilization, 28 (21.4%) for immobilization, and 10 (7.6%) for traction. Methods. One-way analyses of variance and Kruskal-Wallis tests were used to investigate differences in clinical variables by TBC group. Then, discriminant function analysis (DFA) predicted TBC group membership. Results. The TBC groups differed on present pain intensity, duration of LBP, and history of LBP. Present pain intensity, duration of LBP, total lumbar flexion, presence of leg pain, and history of LBP produced 2 statistically significant discriminant functions that predicted TBC group membership. These functions correctly classified (cross-validation value in parentheses) 65% (65%) for specific exercise, 45% (40%) for mobilization, and 32% (32%) for immobilization. Discussion and Conclusion. This study provided evidence supporting the discriminant validity of TBC. Additional diagnostic information related to TBC groups was generated.
Continuous-Scale Physical Functional Performance Test: Validity, Reliability, and Sensitivity of Data for the Short Version
Authors: Cress M Elaine , Petrella John K , Moore Trudy L , Schenkman Margaret L
Published: February 2017

Background and Purpose. The Continuous-Scale Physical Functional Performance Test (CS-PFP) can be used to obtain valid, reliable, and sensitive measurements of physical functional capacity. This test requires a fixed laboratory space and approximately 1 hour to administer. This study was carried out in 4 steps, or substudies, to develop and validate a short, community-based version (PFP-10) that requires less space and equipment than the CS-PFP. Subjects and Methods. Retrospective data (n=228) and prospective data (n=91) on men and women performing the CS-PFP or the PFP-10 are reported. A 12-week exercise program was used to examine sensitivity to change. Data analyses were done using paired t-test, Pearson correlation, intraclass correlation coefficient (ICC), and delta index (DI) procedures. Results. The PFP-10 total score and 4 of the 5 domain scores were statistically similar (within 3%) to those of the CS-PFP. The PFP-10 upper-body strength domain score was 17% lower, but was highly correlated (ICC=.97). Community and established laboratory PFP-10 scores were similar (ICC=.85–.97). The PFP-10 also is sensitive to change (DI=.21–.54). Discussion and Conclusion. The PFP-10 yields valid, reliable, and sensitive measurements and can be confidently substituted for the CS-PFP.
Classification, Intervention, and Outcomes for a Person With Lumbar Rotation With Flexion Syndrome
Authors: Van Dillen Linda R , Sahrmann Shirley A , Wagner Joanne M
Published: February 2017

Background and Purpose. The purpose of this case report is to describe the classification, intervention, and outcomes for a patient with lumbar rotation with flexion syndrome. Case Description. The patient was a 22-year-old man with a medical diagnosis of low back strain. Impairments in lumbar flexion and right rotation and lateral bending were identified. Daily activities and positions associated with these actions were associated with increased low back pain (LBP). Instruction focused on modifying lumbar rotation and flexion movements and alignments in daily activities. Exercises to address the direction-specific impairments were prescribed. Outcomes. The patient participated in 4 visits and completed a questionnaire 1 year after intervention. The patient reported a decrease in symptoms, disability, and frequency of recurrences. Discussion. Repetition of specific strategies (alignment and movement) during activities may result in specific impairments that contribute to LBP. Modification of the strategies and exercises to change contributing factors are proposed to help alleviate symptoms, disability, and recurrences.

Published: February 2017

Background and Purpose. Ultrasound (US) is one of the most common modalities used in intervention for musculoskeletal disorders, although its effectiveness is debated. The purpose of this case report is to describe the intervention, including the use of US, in the management of a large rectus sheath hematoma (RSH) in a patient receiving anticoagulant therapy. Case Description. The patient was a 62-year-old woman with RSH who was receiving oral anticoagulant therapy and had a history of bouts of coughing. Computed tomographic scans verified the diagnosis of RSH. The report describes the patient examination, management, intervention, and outcomes. Outcomes. The intervention, including the use of US therapy, may have enabled a rapid resolution of the hematoma. Discussion. This case report illustrates how US may be a useful modality for complementary management of RSH, helping the reabsorption of the hematoma.
Changes in Physical Therapy Providers' Use of Fall Prevention Strategies Following a Multicomponent Behavioral Change Intervention
Authors: Brown Cynthia J , Gottschalk Margaret , Van Ness Peter H , Fortinsky Richard H , Tinetti Mary E
Published: February 2017

Background and Purpose. An abundance of evidence suggests that interventions targeting fall risk factors are effective; however, it remains unknown whether, or to what extent, this body of evidence has affected the clinical practice of physical therapy providers. The purposes of this study were: (1) to describe knowledge of, and attitudes toward, fall risk factors and fall reduction strategies; (2) to assess self-reported use of fall reduction strategies with patients; and (3) to identify factors associated with increased use of fall reduction strategies with patients among physical therapy providers exposed to a behavioral change strategy. Subjects and Methods. A cross-sectional survey of physical therapy providers from hospital-based and freestanding outpatient physical therapy facilities throughout north-central Connecticut was conducted between October 2002 and April 2003. The participants were 94 physical therapy providers who had been exposed to the Connecticut Collaboration for Fall Prevention (CCFP) behavioral change effort. The CCFP program uses multicomponent professional behavioral change strategies to embed fall risk factor assessment and management, based on evidence from randomized controlled trials, into the clinical care of older patients. A telephone questionnaire—focusing on fall risk factor knowledge and attitudes and self-reported fall risk factor assessment and management practices before and after exposure to the CCFP efforts—was administered to consenting physical therapy providers. Results. Environmental hazards and gait and balance deficits were named as fall risk factors by 86 (91%) and 73 (78%) participants, respectively. All of the targeted risk factors were mentioned by at least 30% of the participants. Sixty-four participants (68%) reported increased fall reduction practice behaviors. The area of multiple medications was noted most frequently, with 77 participants (82%) noting new practices related to medication use. Only knowledge of fall risk factors and pre-CCFP behaviors were associated with increased fall reduction practices. Discussion and Conclusion. Physical therapy providers reported an increase in practice behaviors in response to the multicomponent behavioral change strategy. Knowledge of fall risk factors was associated with increased fall reduction practice behaviors, most likely due to the focused nature of the education strategy.

Published: February 2017

Background and Purpose. Obstacle crossing is compromised following stroke. The purpose of this study was to quantify modifications during obstacle clearance following stroke. Subjects. Twelve subjects with stroke and 12 subjects without stroke participated in the study. Methods. Kinematic variables were measured while participants crossed a 4-cm-high obstacle. Subjects with stroke walked at a self-selected speed; subjects without stroke walked at a comparable speed and at a self-selected speed. Results. Several modifications were observed following stroke with both groups walking at self-selected speeds. The affected lead limb was positioned closer to the obstacle before crossing. Affected trail-limb clearance over the obstacle was reduced. Both affected and unaffected lead and trail limbs landed closer to the obstacle after clearance. Swing time was increased in the affected lead limb after obstacle clearance. Fewer modifications were detected at matched walking speed; the trail limb still landed closer to the obstacle. Discussion and Conclusion. Modifications during obstacle crossing following stroke may be partly related to walking speed. The findings raise issues of safety because people with stroke demonstrated reduced clearance of a 4-cm obstacle and limb placement closer to the obstacle after clearance.
A New Method of Isometric Dynamometry for the Craniocervical Flexor Muscles
Authors: O'Leary Shaun P , Vicenzino Bill T , Jull Gwendolen A
Published: February 2017

Background and Purpose. A new method of dynamometry has been developed to measure the performance of the craniocervical (CC) flexor muscles by recording the torque that these muscles exert on the cranium around the CC junction. This report describes the method, the specifications of the instrument, and the preliminary reliability data. Subjects and Methods. For the reliability study, 20 subjects (12 subjects with a history of neck pain, 8 subjects without a history of neck pain) performed, on 2 occasions, maximal voluntary isometric contraction (MVIC) tests of CC flexion in 3 positions within the range of CC flexion and submaximal sustained tests (20% and 50% of MVIC) in the middle range of CC flexion (craniocervical neutral position). Reliability coefficients were calculated to establish the test-retest reliability of the measurements. Results. The method demonstrated good reliability over 2 sessions in the measurement of MVIC (intraclass correlation coefficient [ICC]=.79–.93, SEM=0.6–1.4 N·m) and in the measurement of steadiness (standard deviation of torque amplitude) of a sustained contraction at 20% of MVIC (ICC=.74–.80, SEM=0.01 N·m), but not at 50% of MVIC (ICC=.07–.76, SEM=0.04–0.13 N·m). Discussion and Conclusion. The new dynamometry method appears to have potential clinical application in the measurement of craniocervical flexor muscle performance.

Published: February 2017

Background and Purpose. The relationship between abnormal postural coordination and back pain is unclear. The Alexander Technique (AT) aims to improve postural coordination by using conscious processes to alter automatic postural coordination and ongoing muscular activity, and it has been reported to reduce low back pain. This case report describes the use of the AT with a client with low back pain and the observed changes in automatic postural responses and back pain. Case Description. The client was a 49-year-old woman with a 25-year history of left-sided, idiopathic, lumbrosacral back pain. Automatic postural coordination was measured using a force plate during horizontal platform translations and one-legged standing. Outcomes. The client was tested monthly for 4 months before AT lessons and for 3 months after lessons. Before lessons, she consistently had laterally asymmetric automatic postural responses to translations. After AT lessons, the magnitude and asymmetry of her responses and balance improved and her low back pain decreased. Discussion. Further research is warranted to study whether AT lessons improve low back pain-associated abnormalities in automatic postural coordination and whether improving automatic postural coordination helps to reduce low back pain.

Background and Purpose. Although pressure-reducing interventions have been effective in the healing of neuropathic foot ulcers, these ulcers frequently recur in people with diabetes mellitus (DM). This case report illustrates how sudden changes in weight-bearing activity may have affected ulcer recurrence in a patient with DM and how the physical stress theory (PST) relates to ulcer recurrence for this patient. Case Description. The patient was a 66-year-old man with a history of DM, peripheral neuropathy, and recurrent plantar ulcers. His plantar ulcer healed after total contact casting. Outcome. Despite relatively low peak plantar pressure (9.3 N/cm2), the patient's ulcer recurred within 4 weeks of healing. Plantar pressure assessment and activity monitoring suggested that a rapid and sudden increase in weight-bearing activity (steps per day) contributed to cumulative plantar tissue stress that was 3.3 times higher on the day of ulcer recurrence than his average value. Although his cumulative plantar stress was high compared with his usual value, the cumulative value was similar to the amount of daily stress of individuals without a history of recurrent ulcers. Discussion. Within the context of the PST, rapid change in activity level may have an effect on cumulative stress and the risk of ulcer recurrence.
The L Test of Functional Mobility: Measurement Properties of a Modified Version of the Timed “Up & Go” Test Designed for People With Lower-Limb Amputations
Authors: Deathe A Barry , Miller William C
Published: February 2017

Background and Purpose. Walk tests provide essential outcome information when assessing ambulation of individuals with lower-limb amputation and a prosthetic device. Existing tests have limitations such as ceiling effects or insufficient challenge. The objective of this study was to assess the reliability and validity of data for a clinical measure of basic mobility, the L Test of Functional Mobility (L Test). Subjects. For this methodological study, 93 people with unilateral amputations (74% transtibial, 26% transfemoral; 78% male, 22% female; mean age=55.9 years) were consecutively recruited from an outpatient clinic. Twenty-seven subjects returned for retesting. Methods. To assess concurrent validity, subjects completed the L Test, Timed “Up & Go” Test (TUG), 10-Meter Walk Test, and 2-Minute Walk Test, followed by the Activities-specific Balance Confidence scale, Frenchay Activities Index (FAI), and mobility subscale of the Prosthetic Evaluation Questionnaire (PEQ-MS). Amputation cause and level, walking aid use, automatic stepping, and age variables were used to assess discriminant validity. Results. Intraclass correlation coefficients were .96 for interrater reliability and .97 for intrarater reliability, and minimal bias existed upon retesting. The magnitude of concurrent validity correlations (r) was very high between the L Test data and data for other walk tests and fair to moderate between the L Test data and data for self-report measures. The L Test discriminated between all groups as hypothesized. Discussion and Conclusion. The L Test is a 20-m test of basic mobility skills that includes 2 transfers and 4 turns. It demonstrated excellent measurement properties in this study.

Background and Purpose. The majority of patients after a hip fracture do not return to prefracture functional status. Depression has been shown to affect recovery. Although exercise can reduce impairments, access issues limit elderly people from participating in facility-based programs. The primary purpose of this study was to determine the effects and feasibility of a home exercise program of moderate- or high-intensity exercise. A secondary purpose was to explore the relationship of depression and physical recovery. Subjects. Thirty-three elderly people (24 women, 9 men; X̄=78.6 years of age, SD=6.8, range=64-89) who had completed a regimen of physical therapy following hip fracture participated in the study. Subjects were randomly assigned to a resistance training group, an aerobic training group, or a control group. Methods. Subjects were tested before and upon completion of the exercise trial. Isometric lower-extremity force, 6-minute-walk distance, free gait speed, mental status, and physical function were measured. Each exercise session was supervised by a physical therapist, and subjects received 20 visits over 12 weeks. The control group received biweekly mailings. The resistance training group performed 3 sets of 8 repetitions at the 8-repetition maximum intensity using a portable progressive resistance exercise machine. The aerobic training group performed activities that increased heart rate 65% to 75% of their age-predicted maximum for 20 continuous minutes. Results. Resistance and aerobic training were performed without apparent adverse effects, and adherence was 98%. All groups improved in distance walked, force produced, gait speed, and physical function. Isometric force improved to a greater extent in the intervention groups than in the control group. Depressive symptoms interacted with treatment group in explaining the outcomes of 6-minute-walk distance and gait speed. Discussion and Conclusion. High-intensity exercise performed in the home is feasible for people with hip fracture. Larger sample sizes may be necessary to determine whether the exercise regimen is effective in reducing impairments and improving function. Depression may play a role in the level of improvement attained.
Comparison of 2 Quality-of-Life Questionnaires in Women Treated for Breast Cancer: The RAND 36-Item Health Survey and the Functional Living Index–Cancer
Authors: Wilson Rick W , Hutson Lorraine M , VanStry Deborah
Published: February 2017

Background and Purpose. A variety of health status questionnaires have been used in physical rehabilitation studies involving women with breast cancer, but the usefulness of these questionnaires as measures of physical, mental, and social well-being has not been firmly established in this population. This study was conducted to assess the convergent and discriminative properties of the RAND 36-Item Health Survey and the Functional Living Index–Cancer (FLIC). Subjects Both questionnaires were administered concurrently to 110 outpatients treated surgically for breast cancer at a National Cancer Institute–designated Comprehensive Cancer Center. Methods Bivariate correlations and a multi-trait–multi-method matrix were used to evaluate convergent validity between summary and subscale scores from both questionnaires. Discriminative validity was assessed by testing for expected differences between women who were treated for breast cancer with and without secondary lymphedema. Results Correlations between overall quality-of-life scores produced by both questionnaires were modest, indicating that the instruments focus on somewhat different aspects of health-related quality of life. Global quality-of-life and physical well-being scores were lower among women with lymphedema secondary to breast cancer. The FLIC demonstrated greater sensitivity to group differences in emotional well-being. Discussion and Conclusion The results suggest that neither questionnaire can be replaced by the other in studies of women treated for breast cancer. Both questionnaires were able to distinguish physical functioning deficits in women with lymphedema secondary to breast cancer, but symptom- or treatment-specific measures may be required to assess more subtle difficulties related to the emotional aspects of health and functioning in this population.
Management of Back and Neck Pain: Who Seeks Care From Physical Therapists?

Published: February 2017

Background and Purpose Little information is available on factors associated with physical therapist use by people with back or neck pain. Identifying the characteristics of people who seek care from physical therapists is a useful first step in determining whether there is appropriate use of physical therapy services. The purpose of this study was to identify factors associated with physical therapist use by people with back or neck pain. Subjects The subjects were 29,049 people who had back pain or neck pain, or both, and who were seen for an initial evaluation at 1 of 21 US spine care centers. Each subject and evaluating physician completed a written survey at the time of the initial evaluation. Methods Multiple logistic regression analyses were conducted to identify factors associated with physical therapist use. Results Several measures of health and illness severity were associated with physical therapist use. Age and being male were negatively associated with physical therapist use. Education level, having workers' compensation coverage, and being in litigation were positively associated with physical therapist use. Physical therapist use also varied by previous physician use and census region. Discussion and Conclusion The results suggest that variations in physical therapist use are associated with factors other than health and illness severity. The results also suggest that people who would benefit from physical therapy may not be receiving it or that people who would not benefit from physical therapy are receiving it, or both.
