Background
Relationships between low back pain (LBP) and the hip in patient cohorts have been described primarily in patients with moderate to severe hip osteoarthritis (OA). Less is known about the links of LBP with hip radiographic findings of hip deformity and minimal OA.Objective
To describe the incidence of radiographic hip deformity or hip OA; to describe and compare spine- and hip-related pain and function in the subset of patients who were found to have radiographic hip deformity or hip OA; and to compare patients with evidence of radiographic hip deformity or hip OA to patients without hip radiographic findings.Design
Prospective cohort study with cross-sectional design.Setting
Tertiary university.Patients
A total of 63 patients (40 women, 23 men) with a mean age of 48.5 ± 14 years with LBP and a minimum of one positive provocative hip test.Methods
Hip radiographs were assessed by an independent examiner for hip OA and deformity.Main Outcome Measurements
Comparisons of hip and lumbar spine pain and function were completed for patients with radiographic findings of hip OA or deformity.Results
Moderate to severe hip OA was found in 12 of 60 patients (20.0%). At least one measurement of femoroacetabular impingement (FAI) was found in 14 of 60 patients (23.3%) to 33 of 45 patients (73.3%). At least one measurement of developmental hip dysplasia (DDH) was found in 7 of 60 patients (11.6%) to 11 of 63 patients (17.4%). Greater pain and reduced hip and lumbar spine function were found in the patients with moderate to severe hip OA. Patients with LBP and FAI were found to have significantly greater extremes of pain and reduced lumbar spine function.Conclusion
Links between the hip and the spine affecting pain and function may be found in patients with LBP and hip deformity and before the onset of radiographic hip OA, and may be associated with hip deformity. Further investigation is needed to better understand these links and their potential impact on prognosis and treatment of LBP.Level of Evidence

Background
In young and middle-aged adults with and without hip deformity, hip pain receives treatment focused primarily related to hip structure. Because this hip pain may be chronic, these patients develop other coexisting, modifiable disorders related to pain that may go undiagnosed in this young and active population, including insomnia and anxiety.Objective
The objective of this study was to compare assessments of insomnia and anxiety in young and middle-aged adults presenting with hip pain with no greater than minimal osteoarthritis (OA) compared to asymptomatic healthy controls. Comparisons between types of hip deformity and no hip deformity in hip pain patients were performed to assess whether patients with specific hip deformities were likely to have insomnia or anxiety as a cofounding disorder to their hip pain.Design
Prospective case series with control comparison.Setting
Two tertiary university physiatry outpatient clinics.Participants
A total of 50 hip pain patients aged 18-40 years and 50 gender- and age-matched healthy controls.Methods
Patients were enrolled if 2 provocative hip tests were found on physical examination and hip radiographs had no or minimal OA. Radiographic hip deformity measurements were completed by an independent examiner. Comparisons of insomnia and anxiety were completed between 50 hip pain patients and 50 controls and between patients with different types of hip deformity.Main Outcome Measures
Insomnia Severity Index (ISI) and Pain Anxiety Symptoms Scale (PASS).Results
A total of 50 hip pain patients (11 male and 39 female) with mean age of 31.2 ± 8.31 years enrolled. Hip pain patients slept significantly less (P = .001) per night than controls. Patients experienced significantly greater insomnia (P = .0001) and anxiety (P = .0001) compared to controls. No differences were found in insomnia and anxiety scores between hip pain patients with and without hip deformity or between different types of hip deformity.Conclusion
Hip pain patients with radiographs demonstrating minimal to no hip arthritis with and without hip deformity experience significant cofounding yet modifiable disorders of sleep and anxiety. If recognized early in presentation, treatment of insomnia and anxiety ultimately will improve outcomes for hip patients treated either conservatively or surgically for their hip disorder.Level of Evidence

Background
Intra-articular corticosteroid injection is a commonly used therapy for adhesive capsulitis, but not enough studies exist on the optimal timing of the injection.Objective
To determine whether intra-articular corticosteroid injection has better outcomes in patients with earlier stage than later stage of adhesive capsulitis.Study Design
Retrospective longitudinal studySetting
University-affiliated tertiary care hospital.Participants
Primary adhesive capsulitis patients (n=339) who were unresponsive to at least 1 month of conservative treatment and who had ultrasound-guided corticosteroid injection.Interventions
Not applicable.Main Outcome Measurements
Visual analogue scale, Shoulder Pain and Disability Index, and passive range of motion (flexion, abduction, external rotation, and internal rotation and extension) were evaluated at pretreatment, month 1 and 12 after the first injection.Results
The result of the multiple regressions, which considered the main and the interaction effect of confounding variables, showed that the differences of all outcomes in both short-term effect at month 1 and long-term effect at month 12 are greater when the duration of pain prior to injection is shorter. Among the confounders, the injection number in the difference of internal rotation and extension between month 0 and 12 (IRE Δ(0-12)) was statistically significant. IRE Δ(0-12) was also greater when the pain duration was shorter, though the decrease in IRE Δ(0-12) differed depending on the number of injections.Conclusions
Early injection improves outcomes of adhesive capsulitis at both short- and long-term follow-ups. If pain persists despite non-invasive and conservative treatments, early injection may be considered to shorten its natural history.Level of Evidence

Background
A timely return to competitive sport is a primary goal of anterior cruciate ligament reconstruction (ACLR). It is not known whether an accelerated return to sport increases the risk of early-onset knee osteoarthritis (KOA).Objective
To determine whether an accelerated return to sport post-ACLR (ie, <10 months) is associated with increased odds of early KOA features on magnetic resonance imaging (MRI) 1 year after surgery and to evaluate the relationship between an accelerated return to sport and early KOA features stratified by type of ACL injury (isolated or concurrent chondral/meniscal injury) and lower limb function (good or poor).Design
Cross-sectional study.Setting
Private radiology clinic and university laboratory.Participants
A total of 111 participants (71 male; mean age 30 ± 8 years) 1-year post-ACLR.Methods
Participants completed a self-report questionnaire regarding postoperative return-to-sport data (specific sport, postoperative month first returned), and isotropic 3-T MRI scans were obtained.Outcome Measures
Early KOA features (bone marrow, cartilage and meniscal lesions, and osteophytes) assessed with the MRI OA Knee Score. Logistic regression analyses evaluated the odds of early KOA features with an accelerated return to sport (<10 months post-ACLR versus ≥10 months or no return to sport) in the total cohort and stratified by type of ACL injury and lower limb function.Results
Forty-six (41%) participants returned to competitive sport <10 months post-ACLR. An early return to sport was associated with significantly increased odds of bone marrow lesions (odds ratio [OR] 2.7, 95% confidence interval [CI] 1.3-6.0) but not cartilage (OR 1.2, 95% CI 0.5-2.6) or meniscal lesions (OR 0.8, 95% CI 0.4-1.8) or osteophytes (OR 0.6, 95% CI 0.3-1.4). In those with poor lower limb function, early return to sport exacerbated the odds of bone marrow lesions (OR 4.6, 95% CI 1.6-13.5), whereas stratified analyses for type of ACL injury did not reach statistical significance.Conclusion
An accelerated return to sport, particularly in the presence of poor lower limb function, may be implicated in posttraumatic KOA development.Level of evidence

Objective
To examine if a comorbid diagnosis of knee or hip osteoarthritis (OA) in older adults with new back pain visits is associated with long-term patient-reported outcomes and back-related health care use.Design
Prospective cohort study.Setting
Three integrated health systems forming the Back pain Outcomes using Longitudinal Data cohort.Participants
Participants (N=5155) were older adults (≥65y) with a new visit for back pain and a complete electronic health record data.Interventions
Not applicable; we obtained OA diagnoses using diagnostic codes in the electronic health record 12 months prior to the new back pain visit.Main Outcome Measures
The Roland-Morris Disability Questionnaire (RDQ) and the EuroQol-5D (EQ-5D) were key patient-reported outcomes. Health care use, measured by relative-value units (RVUs), was summed for the 12 months after the initial visit. We used linear mixed-effects models to model patient-reported outcomes. We also used generalized linear models to test the association between comorbid knee or hip OA and total back-related RVUs.Results
Of the 5155 participants, 368 (7.1%) had a comorbid knee OA diagnosis, and 94 (1.8%) had a hip OA diagnosis. Of the participants, 4711 (91.4%) had neither knee nor hip OA. In adjusted models, the 12-month RDQ score was 1.23 points higher (95% confidence interval [CI], 0.72–1.74) for patients with knee OA and 1.26 points higher (95% CI, 0.24–2.27) for those with hip OA than those without knee or hip OA, respectively. A lower EQ-5D score was found among participants with knee OA (.02 lower; 95% CI, ?.04 to ?.01) and hip OA diagnoses (.03 lower; 95% CI, ?.05 to ?.01) compared with those without knee or hip OA, respectively. Comorbid knee or hip OA was not significantly associated with total 12-month back-related resource use.Conclusions
Comorbid knee or hip OA in older adults with a new back pain visit was associated with modestly worse long-term disability and health-related quality of life. 相似文献7.

Background
Patients with Parkinson disease (PD) present cardiovascular autonomic dysfunction that impairs blood pressure control. However, cardiovascular responses during resistance exercise are unknown in these patients.Objective
To investigate cardiovascular responses during resistance exercise performed with different muscle masses in patients with PD.Design
Prospective, repeated-measures.Setting
Exercise Hemodynamic Laboratory, School of Physical Education and Sport, University of São Paulo.Participants
Thirteen patients with PD (4 women, 62.7 ± 1.3 years, stages 2-3 of the modified Hoehn and Yahr scale; “on” state of medication) and 13 paired control patients without PD (7 women, 66.2 ± 2.0 years).Interventions
Both groups performed, in a random order, bilateral and unilateral knee extension exercises (2 sets, 10-12 maximal repetition, 2-minute intervals).Main Outcome Measurements
Systolic blood pressure (SBP) and heart rate (HR) were assessed before (pre) and during the exercises.Results
Independent of set and exercise type, SBP and HR increases were significantly lower in PD than the control group (combined values: +45 ± 2 versus +73 ± 4 mm Hg and +18 ± 1 versus +31 ± 2 bpm, P = .003 and .007, respectively). Independently of group and set, the SBP increase was greater in the bilateral than the unilateral exercise (combined values: +63 ± 4 versus +54 ± 3 mm Hg, P = .002), whereas the HR increase was similar. In addition, independently of group and exercise type, the SBP increase was greater in the second than the first set (combined values: +56 ± 4 versus +61 ± 4 mm Hg, P = .04), whereas the HR increases were similar.Conclusions
Patients with PD present attenuated increases in SBP and HR during resistance exercise in comparison with healthy subjects. These results support that resistance exercise is safe and well tolerated for patients with PD from a cardiovascular point of view supporting its recommendation for this population.Level of Evidence

Background
Home-based therapy optimizing biomechanics and neuromuscular control is increasingly recognized as a treatment option for chronic nonspecific low back pain (CNSLBP). However, its impact on pain, function, and gait is limited among patients in a metropolitan area.Objective
To evaluate the change of pain, function, and gait parameters with home-based therapy with the use of footwear-generated biomechanical manipulation and perturbation training in a population with CNSLBP in a metropolitan area.Design
Prospective observational study.Setting
Outpatient rehabilitation clinic at an academic teaching hospital.Participants
One hundred sixteen patients with CNSLBP for more than 6 months.Intervention
Six months of home-based therapy with a biomechanical device using 4 modular elements attached to a foot-worn platform.Main Outcome Measures
Instrumental gait analysis (gait velocity, step length, single limb support phase % of gait cycle), Numeric Rating Scale for pain, and Oswestry Disability Questionnaire Index for pain and function.Results
Only 43 patients (37.1%) completed the study. Among 43 patients, mean gait velocity increased from 86.6 ± 20.7 to 99.7 ± 22.1 cm/s (P < .0001) in 6 months. Mean left step length increased from 51.1 ± 8.4 to 54.8 ± 9.8 cm (P < .0001). Mean right step length increased from 51.0 ± 7.9 to 55.4 ± 9.0 cm (P < .0001). Mean single limb support increased from 36.4 ± 2.8 to 37.2 ± 2.5%, (P = .208) in the right side and from 36.6 ± 3.0 to 37.8 ± 4.4%, (P = .019) in the left side. Median Oswestry Disability Questionnaire Index score improved from 28 (18-44; interquartile range) to 17 (10-35) (P = .045). Mean Numeric Rating Scale for back pain improved from 7.7 ± 1.8 to 3.3 ± 3.1 (P < .0001).Conclusion
At 6 months, patients with CNSLBP undergoing home-based therapy with footwear-generated biomechanical manipulation and perturbation training demonstrated significant improvement of objective gait parameters, pain, and function.Level of Evidence

Background
Women are at greater risk for knee osteoarthritis and numerous other lower limb musculoskeletal disorders. Arch drop during pregnancy and the resultant excessive pronation of the feet may alter loading patterns and contribute to the greater prevalence of knee osteoarthritis in women.Objective
To determine the effect of arch drop on tibial rotation and tibiofemoral contact stress.Design
Interventional study with internal control.Setting
Biomechanics laboratory.Participants
Eleven postpartum women (age 33.4 ± 5.3 years, body mass 76.1 ± 13.5 kg) who had lost arch height with pregnancy in a previous study.Methods
Subjects underwent standing computed tomography (SCT) with their knees in a 20° fixed-flexed position with and without semirigid arch supports to reconstitute prepregnancy arch height. Magnetic resonance imaging of the knee was acquired at a flexion angle equivalent to that of SCT. Bone and cartilage were manually segmented on the magnetic resonance images and segmented surfaces were registered to the 3-dimensional SCT image sets for the arch-supported and -unsupported conditions. These models were used to measure changes in tibial rotation, as well as to estimate contact stress in the medial and lateral tibiofemoral compartments, using computational methods.Main Outcome Measures
Change in tibial rotation and tibiofemoral contact stress with arch drop.Results
Arch drop resulted in a mean tibial internal rotation of 0.75 ± 1.33° (P = .02). Changes in mean or peak contact stress were not detected.Conclusions
Arch drop causes internal tibial rotation, resulting in a shift in the tibiofemoral articulation. An associated increase in contact stress was not detected. Internal rotation of the tibia increases stress on the anterior cruciate ligament and menisci, potentially explaining the greater prevalence of knee disorders in postpartum women.Level of Evidence

Background
Preoperative progressive resistance training (PRT) is controversial in patients scheduled for total knee arthroplasty (TKA), because of the concern that it may exacerbate knee joint pain and effusion.Objective
To examine whether preoperative PRT initiated 5 weeks prior to TKA would exacerbate pain and knee effusion, and would allow a progressively increased training load throughout the training period that would subsequently increase muscle strength.Design
Secondary analyses from a randomized controlled trial (NCT01647243).Setting
University Hospital and a Regional Hospital.Patients
A total of 30 patients who were scheduled for TKA due to osteoarthritis and assigned as the intervention group.Methods
Patients underwent unilateral PRT (3 sessions per week). Exercise loading was 12 repetitions maximum (RM) with progression toward 8 RM. The training program consisted of 6 exercises performed unilaterally.Main outcome measures
Before and after each training session, knee joint pain was rated on an 11-point scale, effusion was assessed by measuring the knee joint circumference, and training load was recorded. The first and last training sessions were initiated by 1 RM testing of unilateral leg press, unilateral knee extension, and unilateral knee flexion.Results
The median pain change score from before to after each training session was 0 at all training sessions. The average increase in knee joint effusion across the 12 training sessions was a mean 0.16 cm ± 0.23 cm. No consistent increase in knee joint effusion after training sessions during the training period was found (P = .21). Training load generally increased, and maximal muscle strength improved as follows: unilateral leg press: 18% ± 30% (P = .03); unilateral knee extension: 81% ± 156% (P < .001); and unilateral knee flexion: 53% ± 57% (P < .001).Conclusion
PRT of the affected leg initiated shortly before TKA does not exacerbate knee joint pain and effusion, despite a substantial progression in loading and increased muscle strength. Concerns for side effects such as pain and effusion after PRT seem unfounded.Level of Evidence

Background
Patients have expressed concern about undergoing procedures involving trainees, even with direct attending physician supervision. Little literature has examined the effect of trainee involvement on patient outcomes.Objective
We aimed to evaluate the effect of trainee involvement on patient complications, immediate pain reduction, and fluoroscopic time for different fluoroscopic injection types.Design
Retrospective review.Setting
Four academic outpatient institutions with Accreditation Council for Graduate Medical Education (ACGME)?accredited residency (physical medicine and rehabilitation, or anesthesiology) or fellowship (sports medicine or pain medicine) programs from 2000 to 2015.Patients
All patients receiving fluoroscopically guided hip (HI), sacroiliac joint (SIJI), transforaminal epidural (TFEI), and/or interlaminar epidural injections (ILEI, performed at only 1 institution).Methods
Outcome measures were examined based on the presence or absence of a trainee during the procedure.Main Outcome Measurements
The primary outcome was the number of immediate complications, with secondary outcomes being fluoroscopic time per injection (FTPI) and immediate numeric rating scale percentage improvement.Results
Trainees were involved in 67.0% of all injections (N = 7,833). Complication rates or improvements in numeric rating scale scores showed no significant differences with trainee involvement for any injection type (P > .05). Trainee involvement was associated with increased FTPI for ILEIs (18.2 ± 10.1 seconds with trainees versus 15.1 ± 8.5 seconds without trainees, P < .001), but not for HIs (P = .60) or SIJIs (P = .51). Trainee involvement with TFEIs was dependent on institution for outcome with respect to FTPI (P < .001), with 28.1 ± 17.9 seconds with trainees and 32.1 ± 22.1 seconds without trainees (P = 0.51).Conclusions
This large multicenter study of academic institutions demonstrates that trainee involvement in fluoroscopically guided injections does not affect immediate patient complications or pain improvement. Trainee involvement does not increase fluoroscopic time for most injections, although there is an institutional difference seen. This study supports the notion that appropriate trainee supervision likely does not compromise patient safety for fluoroscopically guided injections.Level of Evidence

Background
People with spina bifida (SB) face personal and environmental barriers to exercise that contribute to physical inactivity, obesity, risk of cardiovascular disease, and poor aerobic fitness. The WHEEL rating of perceived exertion (RPE) Scale was validated in people with SB to monitor exercise intensity. However, the psycho-physiological link between RPE and ventilatory breakpoint (Vpt), the group-normalized perceptual response, has not been determined and would provide a starting point for aerobic exercise in this cohort.Objectives
The primary objectives were to determine the group-normalized RPE equivalent to Vpt based on WHEEL and Borg Scale ratings and to develop a regression model to predict Borg Scale (conditional metric) from WHEEL Scale (criterion metric). The secondary objective was to create a table of interchangeable values between WHEEL and Borg Scale RPE for people with SB performing a load incremental stress test.Design
Cross-sectional observational.Setting
University laboratory.Participants
Twenty-nine participants with SB.Methods
Participants completed a load incremented arm ergometer exercise stress test. WHEEL and Borg Scale ratings were recorded the last 15 seconds of each 1-minute test phase.Outcome Measures
WHEEL and Borg Scale ratings, metabolic measures (eg, oxygen consumption, carbon dioxide production). Determined Vpt via plots of oxygen consumption and carbon dioxide production against time.Results
Nineteen of 29 participants achieved Vpt (Group A). The mean ± standard deviation peak oxygen consumption at Vpt for Group A was 61.76 ± 16.26. The WHEEL and Borg Scale RPE at Vpt were 5.74 ± 2.58 (range 0-10) and 13.95 ± 3.50 (range 6-19), respectively. A significant linear regression model was developed (Borg Scale rating = 1.22 × WHEEL Scale rating + 7.14) and used to create a WHEEL-to-Borg Scale RPE conversion table.Conclusion
A significant linear regression model and table of interchangeable values was developed for participants with SB. The group-normalized RPE (WHEEL, 5.74; Borg, 13.95) can be used to prescribe and self-regulate arm ergometer exercise intensity approximating the Vpt.Level of Evidence

Background
A variety of tests have been proposed to measure the performance of neck flexor muscles, but head-to-head comparisons hardly have been documented.Objective
To compare reliability indexes, construct validity, and ability to discriminate between individuals with and without neck pain of 4 muscle tests (deep neck flexors endurance test [DNFET]; 2 variations of the craniocervical flexion test [CCFT1 and CCFT2]; and dynamometry).Design
Reliability and validity study.Setting
General community.Participants
A total of 66 participants, 33 with chronic idiopathic neck pain (mean ± standard deviation pain intensity: 3.2 ± 1.9) and 33 without neck pain, from the general population.Methods/Main Outcome
Neck muscle functioning was assessed with the CCFT1, the CCFT2, the DNFET, and dynamometry on 2 separate sessions. Participants with neck pain also were assessed for pain intensity, disability, pain catastrophizing, and fear of movement.Results
Relative reliability of all tests was at least moderate (intraclass correlation coefficient ≥ 0.62), whereas measurement error was high, particularly for the DNFET (95% minimum detectable change ≥ 23.00 seconds). All tests showed moderate correlation (r ≥ 0.3) with at least 2 pain-related measures and moderate-to-strong correlations with each other. Principal component analysis retained 2 factors explaining 68%-73% of the variance of the 4 muscle tests. Significant differences between groups were found for the DNFET and dynamometry (P < .05).Conclusion
The reliability indexes suggest that the DNFET and the CCFT may be more appropriate for group comparisons than for individual comparisons. The 4 tests seem to have construct validity, but they also seem to measure slightly different constructs.Level of Evidence

Background
Low back pain (LBP) is commonly associated with paraspinal muscle dysfunctions. A method to study deep lumbar paraspinal (ie, multifidus) muscle function and neuromuscular activation pattern is intramuscular electromyography (EMG). Previous studies have shown that the procedure does not significantly impact muscle function during activities involving low-level muscle contractions. However, it is currently unknown how muscular function and activation are affected during high-exertion contractions.Objective
To examine the effects of insertion and presence of fine-wire EMG electrodes in the lumbar multifidus on muscle strength, endurance, and activation profiles during high-exertion spinal extension muscle contractions.Design
Single-blinded, repeated measures intervention trial.Setting
University clinical research laboratoryParticipants
Twenty individuals between the ages of 18-40 free of recent and current back pain.Methods
Muscle performance was assessed during 3 conditions (with [WI] and without [WO] presence of intramuscular electrodes, and insertion followed by removal [IO]). Isometric spinal extension strength was assessed with a motorized dynamometer. Muscle endurance was assessed using the Sorensen test with neuromuscular activation profiles analyzed during the endurance test.Main Outcome Measurements
Spinal extensor muscle strength, endurance, and activation.Results
Our data showed no significant difference in isometric strength (P = .20) between the 3 conditions. A significant difference in muscle endurance was found (P = .03). Post hoc analysis showed that the muscle endurance in the IO condition was significantly higher than the WO condition (161.3 ± 58.3 versus 142.1 ± 48.2 seconds, P = .04), likely due to a learning effect. All 3 conditions elicited minimal pain (range 0-4/10) and comparable muscle activation profiles.Conclusion
Our findings suggested the sonographically guided insertion and presence of fine-wire intramuscular EMG electrodes in the lumbar multifidus muscles had no significant impact on spinal extension muscle function. This study provides evidence that implementing intramuscular EMG does not affect muscle performance during high-exertion contractions in individuals with no current back pain.Level of Evidence

Background
Osteoarthritis (OA) is considered an established risk factor for falls. Published studies evaluating secondary falls prevention strategies among individuals with OA are limited.Objective
To evaluate the effect of a personalized home-based exercise program to improve postural balance, fear of falling, and falls risk in older fallers with knee OA and gait and balance problems.Design
Randomized controlled trial.Setting
University of Malaya Medical Centre.Participants
Fallers who had both radiological OA and a Timed Up and Go (TUG) score of over 13.5 seconds.Main Outcome Measure
Postural sway (composite sway) was quantified with the Modified Clinical Test of Sensory Interaction on Balance (mCTSIB) under 4 different sensory conditions: eyes open on firm surface, eyes closed on firm surface, eyes open on unstable foam surface, and eyes closed on unstable foam surface. Participants were asked to stand upright and to attempt to hold their position for 10 seconds for each test condition. The average reading for all conditions were calculated.Methods
Participants randomized to the intervention arm received a home-based modified Otago Exercise Program (OEP) as part of a multifactorial intervention, whereas control participants received general health advice and conventional treatment. This was a secondary subgroup analysis from an original randomized controlled trial, the Malaysian Falls Assessment and Intervention Trial (MyFAIT) (trial registration number: ISRCTN11674947). Posturography using a long force plate balance platform (Balancemaster, NeuroCom, USA), the Knee injury and Osteoarthritis Outcome Score (KOOS) and the short-form Falls Efficacy Scale?International (short FES-I) were assessed at baseline and 6 months.Results
Results of 41 fallers with radiological evidence of OA and impaired TUG (intervention, 17; control, 24) were available for the final analysis. Between-group analysis revealed significant improvements in the Modified Clinical Test of Sensory Interaction on Balance (mCTSIB), Limits of Stability (LOS), and short FES-I scores by the intervention group compared to the control group at 6 months. No significant difference in time to first fall or in fall-free survival between the intervention and control groups was found.Conclusion
Home-based balance and strength exercises benefited older fallers with OA and gait and balance disorders by improving postural control, with no observable trend in reduction of fall recurrence. Our findings will now inform a future, adequately powered, randomized controlled study using fall events as definitive outcomes.Level of Evidence

Background
Functional movement disorders (FMDs) are conditions of abnormal motor control thought to be caused by psychological factors. These disorders are commonly seen in neurologic practice, and prognosis is often poor. No consensus treatment guidelines have been established; however, the role of physical therapy in addition to psychotherapy has increasingly been recognized. This study reports patient outcomes from a multidisciplinary FMD treatment program using motor retraining (MoRe) strategies.Objective
To assess outcomes of FMD patients undergoing a multidisciplinary treatment program and determine factors predictive of treatment success.Design
Retrospective chart review.Setting
University-affiliated rehabilitation institute.Patients
Thirty-two consecutive FMD patients admitted to the MoRe program from July 2014–July 2016.Intervention
Patients participated in a 1-week, multidisciplinary inpatient treatment program with daily physical, occupational, speech therapy, and psychotherapy interventions.Main Outcome Measurements
Primary outcome measures were changes in the patient-rated Clinical Global Impression Scale (CGI) and the physician-rated Psychogenic Movement Disorder Rating Scale (PMDRS) based on review of standardized patient videos. Measurements were taken as part of the clinical evaluation of the program.Results
Twenty-four of the 32 patients were female with a mean age of 49.1 (±14.2) years and mean symptom duration of 7.4 (±10.8) years. Most common movement phenomenologies were abnormal gait (31.2%), hyperkinetic movements (31.2%), and dystonia (31.2%). At discharge, 86.7% of patients reported symptom improvement on the CGI, and self-reported improvement was maintained in 69.2% at the 6-month follow-up. PMDRS scores improved by 59.1% from baseline to discharge. Longer duration of symptoms, history of abuse, and comorbid psychiatric disorders were not significant predictors of treatment outcomes.Conclusions
The majority of FMD patients experienced improvement from a 1-week multidisciplinary inpatient rehabilitation program. Treatment outcomes were not negatively correlated with longer disease duration or psychiatric comorbidities. The results from our study are encouraging, although further long-term prospective randomized studies are needed.Level of Evidence

Patients (N=12) with paraplegic SCI.Interventions
Not applicable.Main Outcome Measures
The inclination angle (IA) of the body’s center of mass (COM) relative to the center of pressure (COP), and the rate of change of IA (RCIA) for balance control, and the mechanical energy and forward COM momentum before and after seat-off for energetics during WRE-assisted STS were compared between conditions with 2 initial hip angles (105° and 115°) and 3 initial hip angular velocities (800, 1000, 1200 rpm).Results
No interactions between the main factors (ie, initial hip angle vs angular velocity) were found for any of the calculated variables. Greater initial hip angle helped the patients with SCI move the body forward with increased COM momentum but reduced RCIA (P<.05). With increasing initial angular hip velocity, the IA and RCIA after seat-off (P<.05) increased linearly while total mechanical energy reduced linearly (P<.05).Conclusions
The current results suggest that a greater initial hip angle with smaller initial angular velocity may provide a favorable compromise between momentum transfer and balance of the body for people with SCI during WRE-assisted STS. The current data will be helpful for improving the design and clinical use of the WRE. 相似文献20.
