Gait- and Posture-Related Factors Associated With Changes in Hip Pain and Physical Function in Patients With Secondary Hip Osteoarthritis: A Prospective Cohort Study

ObjectiveTo identify gait- and posture-related factors associated with changes in hip pain and physical function in patients with hip osteoarthritis (OA).DesignProspective cohort study.SettingClinical biomechanics laboratory of a university.ParticipantsConsecutive sampling of female patients with mild-to-moderate secondary hip OA (N=30).Main Outcome MeasuresHip pain (visual analog scale) and physical function (physical component summary of the Medical Outcomes Study 36-Item Short-Form Health Survey) were measured at baseline and 12 months later. With changes in hip pain and physical function as dependent variables, linear regression analyses were performed with gait- and posture-related factors as independent variables with and without adjustment for age, joint space width, and hip pain or physical function at baseline. Posture-related factors included angles of thoracic kyphosis, lumbar lordosis, sacral inclination, spinal inclination, and spinal mobility. Gait-related factors were walking speed, steps per day, joint angles, external hip joint moment impulses, and daily cumulative hip moments.ResultsMultiple linear regression analyses showed that limited hip extension (adjusted standardized B coefficient [95% confidence interval]: −0.52 [−0.88 to −0.17]) and limited external rotation angles (−0.51 [−0.85 to −0.18]) during walking were associated with the worsening of hip pain. An increased thoracic kyphosis (−0.54 [−0.99 to −0.09]), less sacral anterior tilt (0.40 [0.01-0.79]), reduced thoracic spine mobility (0.59 [0.23-0.94]), less steps per day (0.53 [0.13-0.92]), and a slower walking speed (0.45 [0.04-0.86]) were associated with deterioration in physical function.ConclusionsGait- and posture-related factors should be considered when assessing risk and designing preventive interventions for the clinical progression of secondary hip OA.     

Long-Term Specialized Physical Therapy in Cervical Dystonia: Outcomes of a Randomized Controlled Trial

ObjectiveTo evaluate the effectiveness of a specialized physical therapy (SPT) program on disability in cervical dystonia (CD) compared to regular physical therapy (RPT).DesignA single-blinded randomized controlled trial.SettingThis study was performed by a physical therapist in a primary health care setting. Measurements were performed at baseline, 6 and 12 months in the botulinum toxin (BoNT) outpatient clinic of the neurology department.ParticipantsPatients with primary CD and stable on BoNT treatment for 1 year (N=96).Main Outcome MeasuresThe primary outcome was disability assessed with the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS). Secondary outcomes were pain, anxiety, depression, quality of life (QOL), and health related costs over 12 months.ResultsA total of 72 participants (30 men, 42 women) finished the study: 40 received SPT, 32 RPT. No significant between group differences were found after 12 months of treatment (P=.326). Over these 12 months both groups improved significantly (P<.001) on the TWSTRS disability scale compared to baseline (SPT 1.7 points, RPT 1.0 points). Short Form 36 (SF-36) General Health Perceptions (P=.046) and self-perceived improvement (P=.007) showed significantly larger improvements after 12 months in favor of SPT. Total health related costs after 12 months were $1373±556 for SPT compared to $1614±917 for RPT.ConclusionSPT revealed no significant differences compared to RPT after 12 months of treatment on the TWSTRS disability scale. Both groups showed similar improvements compared to baseline. Positive results in the SPT group were higher patient perceived effects and general health perception. Treatment costs were lower in the SPT group. With lower costs and similar effects, the SPT program seems to be the preferred program to treat CD.     

Unilateral Strength Training of the Less Affected Hand Improves Cortical Excitability and Clinical Outcomes in Patients With Subacute Stroke: A Randomized Controlled Trial

ObjectivesTo investigate whether unilateral strength training helps improve cortical excitability and clinical outcomes after stroke.DesignRandomized controlled trial.SettingRehabilitation sciences research center.ParticipantsPatients with subacute stroke (N=26) were randomly assigned to a control group (n=13) or the experimental group (n=13).InterventionsParticipants in both groups received conventional physiotherapy. The experimental group also received unilateral strength training of the less affected wrist extensors. Interventions were applied for 4 weeks (12 sessions, 3 d/wk).Main Outcome MeasuresCortical excitability in both the ipsilesional hemisphere (ipsiH) and contralesional hemisphere (contraH) was assessed by measuring resting motor threshold (RMT), active motor threshold (AMT), motor evoked potential (MEP), and cortical silent period (CSP) at baseline and after the 4-week intervention period. Clinical outcomes were obtained by evaluating wrist extension strength in both the more affected and less affected hands, upper extremity motor function, activities of daily living (ADL), and spasticity.ResultsThe experimental group showed greater MEP amplitude (P=.001) in the ipsiH and shorter CSP duration in both the ipsiH (P=.042) and contraH (P=.038) compared with the control group. However, the reductions in RMT and AMT in both hemispheres were not significantly different between groups. Improvements in wrist extension strength in the more affected (P=.029) and less affected (P=.001) hand, upper extremity motor function (P=.04), and spasticity (P=.014) were greater in the experimental group. No significant difference in ADLs was detected between groups.ConclusionsA combination of unilateral strength training and conventional physiotherapy appears to be a beneficial therapeutic modality for improving cortical excitability and some clinical outcomes in patients with stroke.     

Extracorporeal Shock Wave Therapy Combined With Oral Medication and Exercise for Chronic Low Back Pain: A Randomized Controlled Trial

ObjectiveTo compare extracorporeal shock wave therapy combined with oral medication and an exercise program vs sham treatment with medication and exercise for the treatment of chronic low back pain (CLBP).DesignRandomized controlled trial.SettingOutpatient clinic at a university hospital.ParticipantsEligibility criteria were age older than 18 years and duration of CLBP exceeding 3 months. Exclusion criteria were concurrent treatment or history of surgery for CLBP, cancer, fractures, infections, and disk degeneration.InterventionThe intervention group received extracorporeal shock wave therapy once a week for 4 weeks along with oral medications and an exercise program. The control group received sham extracorporeal shock wave therapy along with oral medications and an exercise program.Main Outcome MeasuresVisual analog scale and Oswestry Disability Index (ODI) were used to assess pain and disability at baseline and after 3 months.ResultsThe pain score in the intervention group (N=16) was 6.6 at baseline and 3.0 after 1 month (P<.0001) and 1.8 after 3 months (P<.0001). In the control group (N=16), the pain score was 6.8 at baseline, 4.6 after 1 month (P<.0001), and 1.1 after 3 months (P<.0001). ODI scores decreased significantly in both groups compared with baseline values (first month: P<.001, third month: P<.05). The mean ODI score did not differ significantly between the groups (P=.942).ConclusionExtracorporeal shock wave therapy combined with oral medication and exercise was safe and effective in the short-term treatment of chronic low back pain.     

Robotic-Assisted Shoulder Rehabilitation Therapy Effectively Improved Poststroke Hemiplegic Shoulder Pain: A Randomized Controlled Trial

ObjectiveThe purpose of this study was to investigate the therapeutic effects of a newly developed shoulder robot on poststroke hemiplegic shoulder pain.DesignProspective, single-blind randomized controlled trial.SettingInpatient department of a tertiary university hospital.ParticipantsHemiplegic shoulder pain patients (N=38) were consecutively recruited and randomly assigned to an intervention or control group.InterventionsA newly developed robot was designed to perform joint mobilization and stretching exercises with patients lying in the supine position. Conventional physical therapy directed at both improving upper extremity mechanics and reducing neurologic injury was performed twice per day in both groups. In the intervention group, additional robotic-assisted shoulder rehabilitation therapy was administered for 30 minutes per day, 5 times per week for 4 weeks.Main Outcome MeasuresThe visual analog scale was the primary outcome, and the pain-free passive range of motion of the shoulder joint, the Korean version of the Shoulder Disability Questionnaire, and ultrasonographic grades were the secondary outcomes. The outcomes were evaluated at baseline (T0), postintervention (T1), and a 4-week follow-up (T2).ResultsSignificant time and group interaction effects were found on the visual analog scale, in the abduction passive range of motion, and on the Shoulder Disability Questionnaire (F_2,33=16.384, P=.002; F_2,33=10.609, P=.012; F_2,33=32.650, P=.008, respectively). Significantly higher improvements in these outcome measures were observed in the intervention group than in the control group at T1 after post hoc analysis (P<0.05, all). These improvements were sustained at T2 when the intervention group was compared with the control group (P<.05, all).ConclusionsA prototype shoulder rehabilitation robot as an adjuvant therapy improves hemiplegic shoulder pain and self-reported shoulder-related disability.     

Effectiveness of a Functional Rehabilitation Program for Upper Limb Apraxia in Poststroke Patients: A Randomized Controlled Trial

ObjectiveTo analyze the effectiveness of a home-based restorative and compensatory upper limb apraxia (ULA) rehabilitation program.DesignRandomized controlled trial.SettingNeurology Unit of San Cecilio Hospital and 2 private and specialized health care centers.ParticipantsCommunity dwelling participants (N=38) between the ages of 25 and 95 years old (sex ratio, 1:1) with unilateral mild-to-moderate poststroke lesions (time of evolution since stroke, 12.03±8.98mo) and secondary ULA.InterventionsParticipants were randomly assigned to an 8-week combined ULA functional rehabilitation group (n=19) 3 days per week for 30 minutes or to a traditional health care education protocol group (n=19) once a month for 8 weeks. Both interventions were conducted at home.Main Outcome MeasuresSociodemographic and clinical data, Barthel Index (primary outcome), Lawton and Brody Scale, observation and scoring activities of daily living, the De Renzi tests for ideational and ideomotor apraxia and imitating gestures test, recognition of gestures, test for upper limb apraxia , and stroke-specific quality of life scale were assessed at 3 time points: baseline, posttreatment (8wk), and follow-up (8wk).ResultsThere were statistically significant differences among the groups regarding ideomotor apraxia, imitating gestures, global recognition of gestures, intransitive gestures, and comprehension of gesture production (P<.05) in favor of the experimental group. However, no statistically significant differences were found between the groups regarding functionality or quality of life (P>.05). Regarding the within-group effect, statistically significant differences were found in all neuropsychological outcomes at posttreatment and follow-up (P<.05).ConclusionA functional rehabilitation program was found to be superior to a traditional health care education program and resulted in improvements in neuropsychological functioning in ULA poststroke. Conventional education showed an insufficient effect on apraxia recovery. Further studies with larger sample sizes are needed to determine the effect of rehabilitation strategies on functionality and quality of life of poststroke ULA patients.     

Comorbidities in Patients With End-Stage Knee OA: Prevalence and Effect on Physical Function

ObjectiveTo investigate the prevalence of comorbidities and their effect on physical function, quality of life (QOL), and pain, in patients with end-stage knee osteoarthritis (OA).DesignA cross-sectional study.SettingA rehabilitation facility at university hospital.ParticipantsPatients (N=577; 503 women and 74 men) diagnosed with end-stage knee OA between October 2013 and June 2018.InterventionNot applicable.Main Outcome MeasuresComorbidities were as follows: osteoporosis, presarcopenia, degenerative spine disease, diabetes, and hypertension. All patients completed the following performance-based physical function tests: stair-climbing test (SCT), 6-minute walk test (6MWT), timed Up and Go (TUG) test, and gait analysis. Self-reported physical function and pain were measured using Western Ontario McMaster Universities Osteoarthritis Index (WOMAC) and a visual analog scale (VAS), respectively, and self-reported QOL was measured using EuroQoL 5 dimensions (EQ-5D) questionnaire.ResultsUnivariate analyses revealed that patients with osteoporosis had significantly higher scores in SCT ascent, SCT descent, TUG, WOMAC pain tests, and lower scores in 6MWT, gait speed, and cadence tests than those without osteoporosis. Patients with presarcopenia recorded higher scores in SCT ascent, TUG, EQ-5D, and lower scores in 6MWT and gait speed tests than those without presarcopenia. Patients with degenerative spine disease showed higher scores in WOMAC pain and lower scores in gait speeds than those without degenerative spine disease. Patients with diabetes showed higher scores in SCT ascent than those without diabetes, and patients with hypertension showed lower scores in 6MWT than those without hypertension. After adjusting age, sex, and body mass index, SCT descent retained significant association with osteoporosis, SCT ascent showed independent association with presarcopenia and diabetes, and WOMAC pain revealed significant association with degenerative spine disease.ConclusionThe results confirm associations between comorbidities, performance-based and self-reported physical functions, and QOL in patients with end-stage knee OA.     

Randomized Controlled Trial of a Telephone-Delivered Physical Activity and Fatigue Self-management Interventions in Adults With Multiple Sclerosis

ObjectiveTo compare the effectiveness of telephone-delivered interventions on fatigue, physical activity, and quality of life outcomes in adults with multiple sclerosis (MS).DesignA single-blinded, randomized controlled trial. Participants were randomized to contact-control intervention (CC), physical activity–only intervention (PA-only), and physical activity plus fatigue self-management intervention (FM+). Outcomes were measured at baseline (2wk prerandomization), posttest (14wk postrandomization), and follow-up (26wk postrandomization).SettingTelephone-delivered in Midwest and Northeast regions of the United States.ParticipantsInactive adults with MS (N=208) and moderate-to-severe fatigue.InterventionsThree or 6 group teleconferences followed by 4 individually tailored phone calls delivered during 12 weeks. An occupational therapist and research assistant delivered the teleconferences and tailored phone calls, respectively.Main Outcome MeasuresPrimary outcomes were self-report fatigue and physical activity measured with the Fatigue Impact Scale and Godin Leisure-Time Exercise Questionnaire, respectively. Secondary outcomes included quality of life measured with the Multiple Sclerosis Impact Scale and moderate-to-vigorous exercise and step count measured with an accelerometer.ResultsLinear mixed effects models showed FM+ significantly improved self-reported fatigue (β=−11.08; P=.03) and physical activity (β=0.54; P=.01) compared with CC at posttest. However, FM+ had nonsignificant differences compared with PA-only on self-report fatigue (β=−1.08, P=.84) and physical activity (β=0.09; P=.68) at posttest. PA–only had significant improvements compared with CC on moderate-to-vigorous exercise (β=0.38; P=.02) at posttest and step count at posttest (β=1.30; P<.01) and follow-up (β=1.31; P=.01) measured with an accelerometer. FM+ and PA-only had nonsignificant differences compared with CC on quality of life.ConclusionsGroup teleconferences followed by tailored phone calls have a small yet statistically significant effect in promoting physical activity and reducing fatigue impact in people with MS.     

Effect of Psychomotricity in Combination With 3 Months of Active Shoulder Exercises in Individuals With Chronic Shoulder Pain: Primary Results From an Investigator-Blinded,Randomized, Controlled Trial

ObjectiveTo evaluate whether psychomotor therapy (PMT) in combination with usual care active exercise (AE) rehabilitation for the shoulder is superior to merely AE.DesignThe trial was a single-center, stratified (by corticosteroid injection [yes or no]), randomized, and controlled superiority trial.SettingShoulder unit of the orthopedic department at Hospital Lillebaelt, Vejle Hospital.ParticipantsEligible participants (N=87) were adults aged 18-75 years with shoulder complaints lasting for at least 3 months, in addition to a score equal to or below 3 on the Multidimensional Assessment of Interoceptive Awareness score. Furthermore, patients had at least a visual analog scale pain score of 2 at rest, 3 at night, and 5 in activity (range: 0-10).InterventionsPatients were randomized to 12 weeks of AE (control group) or in combination with 5 PMT sessions (intervention group).Main Outcome MeasureThe primary outcome was the patient-reported outcome score Disability of the Arm, Shoulder and Hand questionnaire. The primary endpoint was 12 weeks after baseline.ResultsThere was no between-group difference in function between the intervention group and control group.ConclusionsOur results showed no additional benefit on patient-reported function and pain from PMT over usual care in patients with long-lasting shoulder pain and low body awareness. This finding suggests that PMT adds no additional benefit to patients’ recovery in relation to pain and active function in comparison to standard care.     

Effects of Virtual Reality vs Conventional Balance Training on Balance and Falls in People With Multiple Sclerosis: A Randomized Controlled Trial

ObjectiveTo assess the efficacy of virtual reality (VR)-based vs conventional balance training on the improvement of balance and reduction of falls in people with multiple sclerosis (PwMS).DesignSingle-blinded, randomized, controlled trial.SettingMusculoskeletal Rehabilitation Research Center, Ahvaz Jundishapur University of Medical Sciences.ParticipantsPwMS (N=39), randomized into VR (n=19) and control (n=20) groups.InterventionThe VR group performed exergames using Kinect, while the control group accomplished conventional balance exercises. Both groups received 18 training sessions for 6 weeks.Main Outcome MeasuresLimits of stability, timed Up and Go (TUG) test, and 10-m walk tests with and without cognitive task and their dual-task costs (DTCs), Berg Balance Scale, Multiple Sclerosis Walking Scale-12, Fall Efficacy Scale-International, Activities-specific Balance Confidence Scale, and fall history were obtained pre- and post intervention and after a 3-month follow-up.ResultsAt both post intervention and follow-up, TUG^cognitive and DTCs on the TUG were significantly lower and the 10-m walk^cognitive was significantly higher in the VR group. At follow-up, reaction time and the number of falls demonstrated significant differences favoring the VR group, whereas the directional control revealed significant difference in favor of the control group (P<.05). The other outcomes showed no statistically significant difference at post intervention or follow-up.ConclusionsBoth the VR-based and conventional balance exercises improved balance and mobility in PwMS, while each acted better in improving certain aspects. VR-based training was more efficacious in enhancing cognitive-motor function and reducing falls, whereas conventional exercises led to better directional control. Further studies are needed to confirm the effectiveness of recruiting VR-based exercises in clinical settings.     

Efficacy of Topical Vibratory Stimulation for Reducing Pain During Trigger Point Injection to the Gastrocnemius: A Randomized Controlled Trial

ObjectiveTo evaluate the efficacy of topical vibratory stimulation for reducing pain during trigger point injection (TPI).DesignDouble-blind randomized placebo-controlled clinical trial.SettingTertiary care university hospital.ParticipantsA total of 136 participants were randomly recruited from among patients with myofascial pain syndrome who were scheduled for TPI. Of these, 65 were excluded because they met the exclusion criteria, and 11 because they refused to participate. Finally, 60 participants were enrolled. No participants dropped out of the study.InterventionParticipants were randomly assigned to the vibration group or control group. TPI was performed with 0.5% lidocaine using a 25-gauge needle. A vibrator was applied to the popliteal fossa for 3 to 5 seconds prior to and during TPI to the gastrocnemius; 100-Hz vibration was turned on for the vibration group and turned off for the control group.Main Outcome MeasuresPain intensity during TPI was assessed using a 100-mm visual analog scale (VAS) as a primary outcome, and participant satisfaction and preference for repeated use were measured using 5-point Likert scales as a secondary outcome. These parameters were evaluated immediately after TPI. The primary outcome was evaluated using analysis of covariance and secondary outcome using the Mann-Whitney U test.ResultsVAS scores for pain during TPI were significantly lower in the vibration group (30.30; 95% confidence interval [CI], 22.65-39.26) compared with the control group (47.58; 95% CI, 38.80-56.52; F=7.74; P< .01). The mean difference in VAS scores between the 2 groups was 17.27 (95% CI, 5.24-29.30). Participant satisfaction and preference for repeated use were significantly higher in the vibration group than in the control group (P<.05). No participant showed any side effects.ConclusionTopical vibratory stimulation significantly decreased pain during TPI of the gastrocnemius.     

Effects of Virtual Reality and Task-Oriented Training on Hand Function and Activity Performance in Pediatric Hand Burns: A Randomized Controlled Trial

ObjectiveTo assess the efficacy of a motion-sensing, hands-free gaming device and task-oriented training (TOT) programs on improving hand function, activity performance, and satisfaction in pediatric hand burns.DesignA randomized controlled trial.SettingOutpatient rehabilitation center.ParticipantsFifty children with deep partial-thickness or full-thickness hand burns. (N=50; mean age, 10.70±1.64y; range, 7-14y)InterventionsChildren were randomized into 1 of the following 3 groups: the motion-sensing, hands-free gaming device group that used interactive video games plus traditional rehabilitation (TR); the TOT group that used real materials plus TR; and the control group that only received TR, all groups received the interventions 3 days per week for 8 weeks.Main Outcome MeasuresWe assessed the children at the baseline and after 8 weeks of intervention. The primary outcome measures were the Jebsen-Taylor Hand Function Test, Duruoz Hand Index (DHI), and Canadian Occupational Performance Measure (COPM). The secondary outcome measures were range of motion (ROM) of the digits, grip strength, and pinch strengths (tip, palmer, and lateral pinch).ResultsThere was a significant increase in all measurements of the motion-sensing, hands-free gaming device and TOT groups compared with that of the control group postintervention (P<.05). There was no significant change in Jebsen-Taylor Hand Function Test, COPM performance, ROM, grip strength, and tip and lateral pinch strengths between the motion-sensing, hands-free gaming device group and TOT group (P>.05), whereas there was a significant increase in DHI, COPM satisfaction, and palmer pinch strength (P<.05) in the motion-sensing, hands-free gaming device group compared with the TOT group postintervention.ConclusionsThe motion-sensing, hands-free gaming device and TOT programs resulted in significant improvement in hand function, activity performance and satisfaction, ROM of the digits, grip strength, and pinch strengths in pediatric hand burns compared with the traditional hand rehabilitation.     

Effect of a Novel Perturbation-Based Pinch Task Training on Sensorimotor Performance of Upper Extremity for Patients With Chronic Stroke: A Pilot Randomized Controlled Trial

ObjectiveTo investigate the effects of perturbation-based pinch task training on the sensorimotor performance of the upper extremities of patients with chronic stroke via a novel vibrotactile therapy system.DesignA single-blinded randomized controlled trial.SettingA university hospital.ParticipantsPatients with chronic stroke (N=19) randomly assigned into either an experimental group or a control group completed the study.InterventionsIn addition to 10 minutes of traditional sensorimotor facilitation, each participant in the experimental group received 20 minutes of perturbation-based pinch task training in each treatment session, and the controls received 20 minutes of task-specific motor training twice a week for 6 weeks.Main Outcome MeasuresThe scores for the primary outcome, Semmes-Weinstein monofilament (SWM), and those for the secondary outcomes, Fugl-Meyer Assessment (FMA), amount of use, quality of movement (QOM) on the Motor Activity Log (MAL) scale, and box and block test (BBT), were recorded. All outcome measures were recorded at pretreatment, post treatment, and 12-week follow-up.ResultsThere were statistically significant between-group differences in the training-induced improvements revealed in the SWM results (P=.04) immediately after training and in the BBT results (P=.05) at the 12-week follow-up. The changes in muscle tone and in the QOM, SWM, and BBT scores indicated statistically significant improvements after 12 sessions of treatment for the experimental group. For the control group, a significant statistical improvement was found in the wrist (P<.001) and coordination (P=.01) component of the FMA score.ConclusionsThis study indicated that the perturbation-based pinch task training has beneficial effects on sensory restoration of the affected thumb in patients with chronic stroke.     

A Comparative Study of Treatment Interventions for Patellar Tendinopathy: A Randomized Controlled Trial

ObjectivesTo determine the additional effect of dry needling (DN) or percutaneous needle electrolysis (PNE) combined with eccentric exercise (EE) and determine which is the most effective for patients with patellar tendinopathy (PT).DesignBlinded, randomized controlled trial, with follow-up at 10 and 22 weeks.SettingsRecruitment was performed in sport clubs. Diagnosis and intervention were conducted at San Jorge University.ParticipantsPatients (N=48) with PT with pain for at least 3 months between the ages of 18 and 45 years.InterventionsThree interventions were carried out: DN and EE, PNE and EE, and EE with sham needle as the control group.Main Outcome MeasuresDisability was measured using the Victorian Institute of Sports Assessment Questionnaire, patellar tendon. Visual analog scale was used to measure pain over time, the Short Form-36 was used to measure quality of life, and ultrasound was used to measure structural abnormalities.ResultsA total of 48 participants (42 men, 6 women; average age, 32.46y; SD, 7.14y) were enrolled. The improvement in disability and pain in each group between baseline and post-treatment and baseline and follow-up was significant (P≤.05), without differences among groups.ConclusionDN or PNE combined with an EE program has not shown to be more effective than a program of only EE to improve disability and pain in patients with PT in the short (10wk) and medium (22wk) terms. Clinical improvements were not associated with structural changes in the tendon.     

Can Yoga or Physical Therapy for Chronic Low Back Pain Improve Depression and Anxiety Among Adults From a Racially Diverse,Low-Income Community? A Secondary Analysis of a Randomized Controlled Trial

ObjectiveTo determine and compare the effect of yoga, physical therapy (PT), and education on depressive and anxious symptoms in patients with chronic low back pain (CLBP).DesignSecondary analysis of a randomized controlled trial.SettingAcademic safety net hospital and 7 community health centers.ParticipantsA total of 320 adults with CLBP.InterventionYoga classes, PT sessions, or an educational book.Outcome MeasureDepression and anxiety were measured using the Patient Health Questionnaire and Generalized Anxiety Disorder 7-item Scale, respectively, at baseline, 12, and 52 weeks. We identified baseline and midtreatment (6-wk) factors associated with clinically meaningful improvements in depressive (≥3 points) or anxious (≥2 points) symptoms at 12 weeks.ResultsParticipants (female=64%; mean age, 46.0±10.7 years) were predominantly non-White (82%), low-income (<$30,000/year, 59%), and had not received a college degree (71%). Most participants had mild or worse depressive (60%) and anxious (50%) symptoms. At 12 weeks, yoga and PT participants experienced modest within-group improvements in depressive symptoms (mean difference [MD]=?1.23 [95% CI, ?2.18 to ?0.28]; MD=?1.01 [95% CI, ?2.05 to ?0.03], respectively). Compared with the education group, 12-week differences were not statistically significant, although trends favored yoga (MD=?0.71 [95% CI, ?2.22 to 0.81]) and PT (MD= ?0.32 [95% CI, ?1.82 to 1.18]). At 12 weeks, improvements in anxious symptoms were only found in participants who had mild or moderate anxiety at baseline. Independent of treatment arm, participants who had 30% or greater improvement in pain or function midtreatment were more likely to have a clinically meaningful improvement in depressive symptoms (odds ratio [OR], 1.82 [95% CI, 1.03-3.22]; OR, 1.79 [95% CI, 1.06-3.04], respectively).ConclusionsIn our secondary analysis we found that depression and anxiety, common in this sample of underserved adults with CLBP, may improve modestly with PT and yoga. However, effects were not superior to education. Improvements in pain and function are associated with a decrease in depressive symptoms. More research is needed to optimize the integration of physical and psychological well-being in PT and yoga.     

Various Surfaces Benefited Functional Outcomes and Fall Incidence in Individuals With Spinal Cord Injury: A Randomized Controlled Trial With Prospective Data Follow-up

ObjectivesTo compare effects of walking training on a walking track with different surfaces (WTDS), including artificial grass, soft, and pebbles, as compared to overground walking training on the functional ability necessary for independence and incidence of falls of ambulatory individuals with spinal cord injury (SCI).DesignA randomized controlled trial (single-blinded design) with 6-month prospective fall data follow-up.SettingTertiary rehabilitation centers and several communities.ParticipantsIndependent ambulatory individuals (N=54) with SCI who walked with or without a walking device.InterventionParticipants were randomly arranged into a control group (overground walking training, n=26) or experimental group (walking training over a WTDS, n=28) for 30 min/d, 5 d/wk over 4 weeks.Main Outcome MeasuresThe 10-m walk test, timed Up and Go test, five times sit-to-stand test, and 6-minute walk test were repeatedly measured 4 times, including before training, and after 2 and 4 weeks, and 6 months. In addition, participants were prospectively monitored for the fall data over 6 months.ResultsParticipants who walked with an average speed of 0.52 m/s and postinjury time >7 years could safely walk over a WTDS. They demonstrated significant improvement at 2 and 4 weeks after experimental training (P<.001), but not after control training. During the 6-month follow-up, participants in the experimental group also had the number of those who fell (n=5, 18%) fewer than those in the control group (n=12, 46%).ConclusionsBeing at a chronic SCI with ability of independent walking, participants needed a challenging task to promote their functional outcomes and minimize fall risk. The findings suggest the use of various surfaces as an alternative rehabilitation strategy for these individuals.     

Effectiveness of Physical Therapy Interventions in Reducing Fear of Falling Among Individuals With Neurologic Diseases: A Systematic Review and Meta-analysis

ObjectiveTo summarize the effectiveness of physical therapy interventions to reduce fear of falling (FOF) among individuals living with neurologic diseases.Data SourcesPubMed, Physiotherapy Evidence Database, Scopus, Web of Science, PsycINFO, Cumulative Index to Nursing and Allied Health, and SportDiscuss were searched from inception until December 2019.Study SelectionClinical trials with either the primary or secondary aim to reduce FOF among adults with neurologic diseases were selected.Data ExtractionPotential articles were screened for eligibility, and data were extracted by 2 independent researchers. Risk of bias was assessed by the Cochrane Risk of Bias tool for randomized controlled trials and the National Institutes of Health Quality Assessment Tool for pre-post studies. A meta-analysis was performed among trials presenting with similar clinical characteristics. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) was used to rate the overall quality of evidence.ResultsSixty-one trials with 3954 participants were included in the review and 53 trials with 3524 participants in the meta-analysis. The included studies presented, in general, with a low to high risk of bias. A combination of gait and balance training was significantly more effective compared with gait training alone in reducing FOF among individuals with Parkinson disease (PD) (mean difference [MD]=11.80; 95% CI, 8.22-15.38; P<.001). Home-based exercise and leisure exercise demonstrated significant improvement in reducing FOF over usual care in multiple sclerosis (MS) (MD=15.27; 95% CI, 6.15-24.38; P=.001). No statistically significant between-groups differences were reported among individuals with stroke and spinal cord injury. The overall quality of evidence presented in this review ranges from very low to moderate according to the assessment with the GRADE approach.ConclusionsGait with lower limb training combined with balance training is effective in reducing FOF in individuals with PD. Also, home-based or leisure exercise is effective among individuals with MS. However, because of several limitations of the included studies, further research is needed to examine the effectiveness of FOF intervention among individuals with neurologic diseases.     

Physical Therapy Use,Costs, and Value for Latent Classes of Good vs Poor Outcome in Patients Who Catastrophize About Their Pain Prior to Knee Arthroplasty

ObjectiveTo examine use, costs, and value of physical therapy (PT) among subgroups.DesignWe conducted an observational study of data from a randomized trial of a pain coping skills intervention. Good and poor outcome subgroups were determined based on Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) Pain and Physical Function scores. The use and costs of PT care as well as changes in WOMAC Pain and Physical Function scores over 4 time periods during a 1-year follow-up were reported. We compared the number of PT visits, total PT costs, and cost per 1-unit improvement in WOMAC scores for the 2 latent subgroups.SettingFive academic medical centers.ParticipantsPatients who catastrophized about their pain prior to knee arthroplasty (N=384).InterventionsPain coping skills training, arthritis education, and usual care.Main Outcome MeasuresThe WOMAC Pain Scale was the primary outcome.ResultsThe value of PT was lower and the cost of PT was higher for poor vs good outcome subgroups beginning 2 months after knee arthroplasty. For example, during the 2- to 6-month period, participants in the poor outcome subgroup incurred a PT cost of $5181.22 per 1-unit improvement in WOMAC Pain compared with $437.87 per 1-unit improvement in WOMAC Pain for the good outcome subgroup (P<.001). From the 6- to 12-month period, WOMAC scores worsened for the poor outcome subgroup, indicating no benefit from PT.ConclusionsPatients in 2 latent classes demonstrated clinically important differences in value of PT. Future research should identify rehabilitation-based interventions that reduce utilization and enhance effectiveness for patients at high risk for poor outcome.     

Unilateral vs Bilateral Hybrid Approaches for Upper Limb Rehabilitation in Chronic Stroke: A Randomized Controlled Trial

ObjectiveTo investigate the effects of unilateral hybrid therapy (UHT) and bilateral hybrid therapy (BHT) compared with robot-assisted therapy (RT) alone in patients with chronic stroke.DesignA single-blind, randomized controlled trial.SettingFour hospitals.ParticipantsOutpatients with chronic stroke and mild to moderate motor impairment (N=44).InterventionUHT combined unilateral RT (URT) and modified constraint-induced therapy. BHT combined bilateral RT (BRT) and bilateral arm training. The RT group received URT and BRT. The intervention frequency for the 3 groups was 90 min/d 3 d/wk for 6 weeks.Main Outcome MeasuresFugl-Meyer Assessment (FMA, divided into the proximal and distal subscale) and Stroke Impact Scale (SIS) version 3.0 scores before, immediately after, and 3 months after treatment and Wolf Motor Function Test (WMFT) and Nottingham Extended Activities of Daily Living (NEADL) scale scores before and immediately after treatment.ResultsThe results favored BHT over UHT on the FMA total score and distal score at the posttest (P=.03 and .04) and follow-up (P=.01 and .047) assessment and BHT over RT on the follow-up FMA distal scores (P=.03). At the posttest assessment, the WMFT and SIS scores of the 3 groups improved significantly without between-group differences, and the RT group showed significantly greater improvement in the mobility domain of NEADL compared with the BHT group (P<.01).ConclusionsBHT was more effective for improving upper extremity motor function, particularly distal motor function at follow-up, and individuals in the RT group demonstrated improved functional ambulation post intervention.
