Sato K, Ogawa T. Reduced trunk muscle mass in patients with stroke is associated with reduced balance function recovery. Clin Nutr ESPEN 2024; 62:115-119. [PMID: 38901932 DOI: 10.1016/j.clnesp.2024.05.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 04/18/2024] [Accepted: 05/07/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND & AIMS Skeletal muscles are essential for postural retention and balance function. However, the relationship between trunk muscle mass (TMM) and balance function has not yet been clarified. This study aimed to examine the impact of TMM on the change in balance function in patients with stroke from admission to a rehabilitation hospital to discharge. METHODS This retrospective observational study included patients aged ≥65 years with cerebral infarction admitted to our rehabilitation hospital from May 2018 to July 2022. The trunk muscle mass index (TMI) was calculated at admission and discharge using bioelectrical impedance analysis. Patients were divided into low and high TMI groups according to the median TMI at admission. The primary outcome was the change in the Berg Balance Scale (BBS) score (BBS score at discharge - BBS score at admission). RESULTS A total of 315 patients (mean age, 78.9 ± 8.0 years; 172 men and 143 women) were included. The median TMI was 7.31 kg/m2 in men and 6.30 kg/m2 in women. Among male patients, the high TMI group had higher BBS scores at admission (31.2 ± 18.2 vs. 23.4 ± 17.7, P = 0.005) and discharge (43.0 ± 15.3 vs. 33.4 ± 19.0, P < 0.001) than those in the low TMI group. After adjusting for confounding factors, TMI at admission was independently associated with the change in BBS score (β = 0.587, P = 0.002). CONCLUSIONS Reduced TMM negatively influences balance function recovery in patients after stroke. A strategy aimed at increasing TMM could have beneficial effects on balance function.

Top Stroke Rehabil 2024:1-9. [PMID: 38785298 DOI: 10.1080/10749357.2024.2356407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Accepted: 04/27/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND Balance self-efficacy is a strong predictor of fall risk after stroke and is related to performance on balance and walking tests. The use of telerehabilitation for delivering stroke rehabilitation has increased in recent years and there is a need to adapt common clinical assessments to be administered in virtual formats, but the association between balance self-efficacy and virtually administered clinical tests of balance performance has yet to be established. This study examined the association between the Activities-specific Balance Confidence (ABC) Scale and virtually administered Timed Up and Go (TUG), Tandem Stand, and Functional Reach tests (FRT) in individuals with stroke. METHODS This was a secondary analysis of baseline data from two telerehabilitation trials with individuals with stroke. All assessments were administered by trained physical therapists through videoconferencing software. Multivariate regression analyses were used to examine the associations between the ABC scale and TUG test, Tandem Stand test, and FRT, adjusted for age and number of comorbidities. RESULTS Data from 51 participants (n = 11 female, median age = 64 [IQR: 18] years, 9.3 ± 4.6 months poststroke) were analyzed. The ABC scores were associated with TUG (R2 = 0.56, F(3,47) = 20.26, p < 0.01), but not Tandem Stand (R2 = 0.18, F(5,45) = 1.93, p = 0.11) or FRT (R2 = 0.14, F(3,47) = 2.55, p = 0.07) tests. CONCLUSION We observed associations between the ABC scores and virtual TUG, but not with Tandem Stand or FRT, which may be attributed to the context-specificity of balance self-efficacy. As virtual administration of outcomes assessments becomes part of common practice in stroke rehabilitation, our study supports the use of virtually administered TUG in stroke.

Abstract
Introduction The C-Brace microprocessor-controlled stance and swing control orthosis has been shown to improve function, mobility, and quality of life. A systematic registry to gather long-term, real-world safety and effectiveness data in patients fit with a C-Brace has not been performed. Methods International multicenter registry. Patients undergoing routine C-Brace fittings were assessed at baseline and 1 year after fitting. Primary outcomes were fast walking speed (FWS) measured by 25-foot or 10-meter walk test, Timed Up and Go (TUG) and the Activity-specific Balance Confidence (ABC) Scale. Secondary and exploratory outcomes included the Patient-specific Functional Scale (PSFS), falls, pain, PROMIS Pain Interference (PI), and quality of life. Results 48 subjects with 1-year baseline and follow up data were analyzed. With the C-Brace, FWS improved by + 0.26 ± 0.33 m/s (p < .0001), TUG by -8.1 ± 14.6 sec (p < .0001), and ABC by + 24.9 ± 25.8% (p < .0001). Mean falls reduced from 33 ± 77 to 3.0 ± 5.6 (p = .0005). PSFS increased by 3.60 ± 2.34 points (p < .0001). Outcomes for pain, PI and quality of life showed significant improvements with the C-Brace. Conclusion The C-Brace is an effective option to improve safety, mobility, and quality of life for patients needing a KAFO for ambulation.

Abstract
BACKGROUND Despite family carepartners of individuals post-stroke experiencing high levels of strain and reduced quality of life, stroke rehabilitation interventions rarely address carepartner well-being or offer training to support their engagement in therapeutic activities. Our group has developed creative intervention approaches to support families during stroke recovery, thereby improving physical and psychosocial outcomes for both carepartners and stroke survivors. The purpose of this study is to test the feasibility of an adapted, home-based intervention (Carepartner Collaborative Integrative Therapy for Gait-CARE-CITE-Gait) designed to facilitate positive carepartner involvement during home-based training targeting gait and mobility. METHODS This two-phased design will determine the feasibility of CARE-CITE-Gait, a novel intervention that leverages principles from our previous carepartner-focused upper extremity intervention. During the 4-week CARE-CITE-Gait intervention, carepartners review online video-based modules designed to illustrate strategies for an autonomy-supportive environment during functional mobility task practice, and the study team completes two 2-h home visits for dyad collaborative goal setting. In phase I, content validity, usability, and acceptability of the CARE-CITE-Gait modules will be evaluated by stroke rehabilitation content experts and carepartners. In phase II, feasibility (based on measures of recruitment, retention, intervention adherence, and safety) will be measured. Preliminary effects of the CARE-CITE-Gait will be gathered using a single-group, quasi-experimental design with repeated measures (two baseline visits 1 week apart, posttest, and 1-month follow-up) with 15 carepartner and stroke survivor dyads. Outcome data collectors will be blinded. Outcomes include psychosocial variables (family conflict surrounding stroke recovery, strain, autonomy support, and quality of life) collected from carepartners and measures of functional mobility, gait speed, stepping activity, and health-related quality of life collected from stroke survivors. DISCUSSION The findings of the feasibility testing and preliminary data on the effects of CARE-CITE-Gait will provide justification and information to guide a future definitive randomized clinical trial. The knowledge gained from this study will enhance our understanding of and aid the development of rehabilitation approaches that address both carepartner and stroke survivor needs during the stroke recovery process.

Abstract
OBJECTIVE To observe the effect of overground gait training with 'Mobility Assisted Robotic System-MARS' on gait parameters in patients with stroke. PATIENTS & METHODS This prospective pre-post study was conducted in a tertiary teaching research hospital with 29 adult stroke patients, with age up to 65 years. Patients fulfilling the inclusion criteria were divided in 2 groups based on the duration of stroke (≤ 6 months-sub-acute & > 6 months-chronic stroke) and provided overground gait training with MARS robot for 12 sessions (1 h/session) over a period of 2-3 weeks. Primary outcome measures were; 10-Meter walk test-10MWT, 6-min' walk test-6MWT and Timed up & Go-TUG tests. Secondary outcome measures were Functional Ambulation Category-FAC, Modified Rankin Scale-MRS and Scandinavian Stroke Scale-SSS. RESULTS No adverse events were reported. Twenty-five patients who were able to perform 10-MWT at the beginning of study were included in the final analysis with 12 in sub-acute and 13 in chronic stroke group. All primary and secondary outcome measures showed significant improvement in gait parameters at the end of the training (p < 0.05) barring 10-Meter walk test in sub-acute stroke group (p = 0.255). Chronic stroke group showed significant minimum clinically important difference-MCID difference in endurance (6MWT) at the end of the training and both groups showed better 'minimal detectable change-MDC' in balance (TUG) at the end of the training. CONCLUSIONS Patients in both the groups showed significant improvement in walking speed, endurance, balance and independence at the end of the training with overground gait training with MARS Robot.

Abstract
INTRODUCTION Telerehabilitation is an accessible service delivery model that may support innovative lower extremity rehabilitation programmes that extend the stroke recovery continuum into the community. Unfortunately, there is limited evidence on the provision of exercises for lower extremity recovery after stroke delivered using telerehabilitation. In response, we developed the TeleRehabilitation with Aims to Improve Lower extremity recovery poststroke (TRAIL) programme, a 4-week progressive exercise and self-management intervention delivered synchronously using video-conferencing technology. Our primary hypothesis is that individual within 1-year poststroke who participate in TRAIL will experience significantly greater improvements in functional mobility than individuals in an attention-controlled education programme (EDUCATION). METHODS AND ANALYSIS In this multisite, parallel group, assessor-blinded randomised attention-controlled trial, 96 community-living stroke survivors within 1-year poststroke will be recruited from five sites (Vancouver, Winnipeg, Toronto, London and Halifax, Canada) from the CanStroke Recovery Trials Platform which is a network of Canadian hospital sites that are affiliated with academic institutions to facilitate participant recruitment and quality trial practices. Participants will be randomised on a 1:1 basis to TRAIL or EDUCATION. Participants randomised to TRAIL will receive eight telerehabilitation sessions where they will perform exercises and receive self-management support to improve lower extremity recovery from a TRAIL physical therapist. The primary outcome will be measured using the Timed Up and Go. Secondary outcomes include lower extremity muscle strength, functional balance, motor impairment, balance self-efficacy, health-related quality of life and health service use for our economic evaluation. Measurements will be taken at baseline, immediately after the intervention, 3-month and 6-month postintervention. ETHICS AND DISSEMINATION Ethics approval for this research has been obtained by all participating sites. All study participants will provide their informed consent prior to enrolling them in the study. Findings from this trial will be disseminated in peer-reviewed journals and presentations at international scientific meetings. TRIAL REGISTRATION NUMBER ClinicalTrials.gov, NCT04908241.

Abstract
Following a pediatric stroke, outcome measures selected for monitoring functional recovery and development vary widely. We sought to develop a toolkit of outcome measures that are currently available to clinicians, possess strong psychometric properties, and are feasible for use within clinical settings. A multidisciplinary group of clinicians and scientists from the International Pediatric Stroke Organization comprehensively reviewed the quality of measures in multiple domains described in pediatric stroke populations including global performance, motor and cognitive function, language, quality of life, and behavior and adaptive functioning. The quality of each measure was evaluated using guidelines focused on responsiveness and sensitivity, reliability, validity, feasibility, and predictive utility. A total of 48 outcome measures were included and were rated by experts based on the available evidence within the literature supporting the strengths of their psychometric properties and practical use. Only three measures were found to be validated for use in pediatric stroke: the Pediatric Stroke Outcome Measure, the Pediatric Stroke Recurrence and Recovery Questionnaire, and the Pediatric Stroke Quality of Life Measure. However, multiple additional measures were deemed to have good psychometric properties and acceptable utility for assessing pediatric stroke outcomes. Strengths and weaknesses of commonly used measures including feasibility are highlighted to guide evidence-based and practicable outcome measure selection. Improving the coherence of outcome assessment will facilitate comparison of studies and enhance research and clinical care in children with stroke. Further work is urgently needed to close the gap and validate measures across all clinically significant domains in the pediatric stroke population.

Abstract
Purpose: This study modified established clinical balance and walking measures and estimated the reliability, validity, and feasibility of using these measures to assess people post-stroke via videoconferencing. Method: Twenty-eight people with chronic stroke were recruited and completed the in-person balance and mobility tests. Five clinical measures were modified as virtual assessments over videoconferencing. Feasibility was evaluated by task completion rate, occurrence of adverse events, and technical difficulties. Test–retest reliability and agreement were examined by intra-class correlations and standard error of measurement between two testing days. Convergent validity was examined by the magnitude of associations between in-person and virtual assessments using Pearson or Spearman rank correlation. Results: Twenty-one participants (52% female) participated in both in-person and virtual assessments. No adverse events occurred. Technical challenges were experienced by eight participants. Test–retest reliability for timed up and go test, 30-seconds sit-to-stand, five-times sit-to-stand, functional reach test, and tandem stance resulted in intra-class coefficients of 0.97, 0.90, 0.77, 0.54, and 0.50 respectively. The standard error of measurement was low across all virtual assessments. The timed up and go test, five-times sit-to-stand, and 30-seconds sit-to-stand showed relationship with in-person assessments ( r = −0.55 to −0.81). Conclusion: Virtual assessment of walking and balance function in ambulatory people post-stroke is feasible; however, technical challenges were experienced. The test–retest reliability of virtual assessments of timed up and go test and sit-to-stand tasks for people with stroke, together with strong convergent validity of the measures compared to in-person assessments is promising.

Abstract
PURPOSE We present the case of a patient with cerebellar ataxia who was treated with walking practice using a split-belt treadmill with disturbance stimulation. The treatment effects were evaluated for improvements in standing postural balance and walking ability. CASE PRESENTATION The patient was a 60-year-old Japanese male who developed ataxia after cerebellar hemorrhage. Assessment was performed using the Scale for the Assessment and Rating of Ataxia, Berg Balance Scale, and Timed Up-and-Go tests. A 10 m walking speed and walking rate were also assessed longitudinally. The obtained values were fit into a linear equation (y = ax + b), and the slope was calculated. This slope was then used as the predicted value for each period relative to the pre-intervention value. After removing the trend of the value for each period relative to the pre-intervention value, the amount of pre- to post-intervention change for each period was calculated to verify the intervention effect. Furthermore, to verify the changes in gait over time, a three-dimensional motion analyzer was used to analyze the pre- and post-intervention gait five times, and the results were kinematically compared. RESULTS No significant pre- to post-intervention changes were observed in the Scale for the Assessment and Rating of Ataxia scores. Conversely, the Berg Balance Scale score, walking rate, and 10 m walking speed increased, and the Timed Up-and-Go score decreased in the B1 period, indicating a marked improvement from the predicted results based on the linear equation. For changes in gait determined using three-dimensional motion analysis, an increase in stride length was observed in each period. CONCLUSION The present case findings suggest that walking practice with disturbance stimulation using a split-belt treadmill does not improve inter-limb coordination, but contributes to improving standing posture balance, 10 m walking speed, and walking rate.

Abstract
PURPOSE This study investigates the reproducibility and concurrent validity of the Rate of Perceived Stability (RPS) Scale in people with stroke. METHODS On two separate days (2-10 days apart), participants provided their RPS ratings during clinical measures: 1)16 tasks from Community Balance and Mobility Scale (CB&M), 2)6-minute walk test (6MWT), and 3)self-paced gait speed. Intraclass correlations (ICCs) assessed between day test-retest reliability of RPS ratings. Standard error of measurement (SEM) and smallest detectable change (SDC) addressed level of between day agreement. Spearman rank correlations (rs) quantified relationships between RPS, and general rating of perceived challenge, task-performance scores. RESULTS Thirty participants with stroke (50% female) participated. ICC ranged from 0.46 to 0.93 across tasks with 12/19 tasks showing ICCs above 0.75 (good test-retest reliability). SEM was 1-point for each task and SDC ranged from 2 to 4 across tasks. Concurrent validity between RPS and ratings of perceived challenge was good-to-excellent (rs ranged 0.78-0.94, p < 0.01). Higher RPS (indicative of feeling less stable) was associated with lower balance performance scores on CB&M tasks, negative relationships ranged in strength from fair to good-to-excellent in 10/16 tasks (rs ranged -0.46 to -0.81, p ≤ 0.01). CONCLUSIONS RPS shows promise as a measure of balance intensity in people with stroke.IMPLICATIONS FOR REHABILITATIONThe RPS is a reliable and valid measure of balance intensity in ambulatory people with stroke.The RPS scale may be a useful clinical tool to address the gap in practice of measuring balance intensity during rehabilitation of walking balance post-stroke.

Abstract
There is a higher rate of falls in the first year after a stroke, and the ability to step in different directions is essential for avoiding a fall and navigating small spaces where falls commonly occur. The lateral transfer of weight is important for stabilizing the body before initiating a step. Hence, understanding the ability to control lateral weight transfer (WT) in different step directions might help understand falls in individuals with stroke. The present study aimed to compare the WT characteristics (onset time, duration, mediolateral center of pressure (ML COP) velocity, and ML COP displacement) and hip abduction torque preceding a lateral and forward voluntary step between individuals with stroke (paretic and non-paretic leg) and controls. Twenty individuals with stroke and ten controls performed voluntary choice reaction tests in the lateral and forward directions. Ten trials (five on each side-right and left) were performed for each step direction. The overall primary findings were that (1) the WT before a lateral step was shorter and initiated earlier, with a larger ML COP displacement and greater hip abductor torque in the stepping leg than the forward step, (2) there was greater hip abductor produced in the stance leg before a forward step than a lateral step, (3) the WT before the lateral step took longer to initiate and was slower to execute in individuals with stroke regardless of the leg (4) the WT before the forward step had more differences in the paretic than the non-paretic leg. Thus, for the first time, it was shown that the WT characteristics and hip abduction torque during the WT are different according to step direction and also appear to be impaired in individuals with stroke. These results have implications for understanding the direction that individuals with stroke are more susceptible to being unable to recover balance and are at risk of falling.

Abstract
Restoration of ambulation is important for stroke patients. Valid and reliable methods are required for the assessment of lower limb functional status. We reviewed the psychometric properties of methods employed to assess lower extremity motor function, ambulation, and balance, with a focus on stroke patients. We define "motor function" as the ability to produce bodily movements when the brain, motor neurons, and muscles interact. "Ambulation" is defined as the ability to walk with or without a personal assistive device, and "balance" as the ability to maintain stability (without falling) during various physical activities. The Motricity Index and Fugl-Meyer Assessment of Lower Extremities assess the motor function of the lower limbs. The Functional Ambulation Category, 10-m Walk Test, and 6-minute Walk Test assess ambulation. The Berg Balance Scale, Timed Up and Go Test, Functional Reach Test, and Trunk Impairment Scale explore balance. All these tests exhibit high-level validity and have good inter-rater and test-retest reliabilities. However, only 3 methods have been formally translated into Korean. The methods discussed here can be used for standardized assessment, personalized goal setting, rehabilitation planning, and estimation of therapeutic efficacy.

Does the stimulus provoking a stepping reaction correlate with step characteristics and clinical measures of balance and mobility post-stroke? Clin Biomech (Bristol, Avon) 2022; 93:105595.

Abstract
BACKGROUND Retraining stepping reactions in people post-stroke is vital. However, the relationship between the stimulus and resulting stepping performance in people post-stroke is unknown. We explored relationships between stepping stimulus and stepping reactions initiated by either paretic or non-paretic legs of people post-stroke and controls. Relationships were examined in the context of clinical measures of balance. METHODS Centre of mass dynamics were measured during self-initiated destabilizing leaning stimuli that required stepping reactions by paretic and non-paretic legs of people post-stroke (n = 10) and controls (n = 10) to recover balance. Step characteristics of the first two steps of stepping reactions were measured. Correlations were calculated between clinical measures of balance and mobility and the centre of mass and step characteristics. FINDINGS Steps were shorter and slower with decreased centre of mass fore-aft and downward displacement and velocity when initiated by paretic and non-paretic legs compared with controls. However, increase in centre of mass displacement and velocity in the fore-aft and downward direction tended to be associated with a greater increase in step length and speed when stepping reactions were initiated by the paretic and non-paretic legs compared with controls. Time to step initiation in response to onset of falling stimulus did not differ between groups. Strong positive correlations were found between clinical balance and mobility scores and centre of mass and step dynamics in fore-aft and vertical directions. INTERPRETATION These results support objective measurement of centre of mass to quantify the stimulus influencing step dynamics and stepping performance during retraining interventions following stroke.

Measuring Balance Abilities of Transtibial Amputees Using Multiattribute Utility Theory. BIOMED RESEARCH INTERNATIONAL 2022; 2021:8340367.

Abstract
Background Berg Balance Scale (BBS) can be considered the standard for assessment of functional balance but has a noted ceiling effect in active transtibial amputees (TTAs). Development of ceiling-free measures based on quantitative measurement techniques that is suitable for patients in any experience levels, yet sensitive enough to capture improvements in any stage of prosthetic rehabilitation, is needed. Research Question. Does a scoring scheme based on Multiattribute Utility (MAU) theory assess balance abilities of multileveled TTAs comparable to BBS? Methods A case-control study including 28 participants (8 novice TTAs, 10 experienced TTAs, and 10 healthy controls) was conducted. Guided by MAU theory, a novel balance model was developed and initially validated by Spearman correlation between index-generated scores and expert assigned scores, providing preliminary evidence of validity. Floor/ceiling effects were tested, and between-group comparisons of static/dynamic balance were conducted by paired t-test or Wilcoxon signed-rank test depending on data distribution normality. Results BBS score was correlated with computed balance index (r = 0.847, p < 0.001). The BBS score of novice/experienced TTAs was 39/54, and the computed balance index was 38/75. A ceiling effect of BBS (30%) was observed in the experienced TTA group, whereas no ceiling effects were found for the computed index in any combination of TTA groups. Group differences between novice and experienced TTAs were observed in center of pressure (COP) ellipse shift area, COP path length, COP average velocity, gait speed, and cadence (all p < 0.05). Significance. Evidence from first stage validation of the proposed MAU balance model indicated that the model performed well. This proposed method can monitor the progress of balance for varied experience-leveled TTAs and provide clinicians with useful information for assessing the rehabilitation training.

Abstract
Acquired brain injury (ABI) is defined as a damage to the brain that occurs after birth. Subjects post-ABI frequently suffer from dynamic balance impairments that persist years after the injury. This study aimed to investigate the effect of a perturbation method using mechatronic shoes that introduce unexpected balance perturbations on the recovery of dynamic balance and gait velocity in chronic ABI participants. In an intervention trial, 35 chronic ABI participants (stroke and traumatic brain injury) participated in 22 sessions of perturbation training, twice a week for 3 months. Dynamic balance was assessed pre- and post-training using Community Balance and Mobility Scale (CB&M). Gait velocity was also assessed in the stroke participants using the 10 Meter Walking Test (10MWT). Dynamic balance improved significantly post-training (P = 0.001). This improvement was greater than the improvement that was observed in a sub-group that was tested twice before training (P = 0.04). Sixteen participants (45.7%) out of 35 met or exceeded minimal detectable change (MDC) of the CB&M Scale. Self-paced velocity also improved significantly (P = 0.02) but only two participants (9.5%) out of 21 exceeded the MDC of 10MWT post-stroke. Our results suggest that unexpected balance perturbation training using mechatronic shoes leads to an improvement in dynamic balance and gait velocity in chronic ABI participants. The advantage of perturbation training using mechatronic shoes with respect to conventional balance training should be further examined.

Abstract
BACKGROUND Evaluating balance in a functional context that integrates challenging tasks frequently performed in the community is essential to identify community-dwelling individuals who are at risk of falls in early Parkinson Disease (PD) than a simple balance measure. Community Balance and Mobility (CB&M) scale is one such measure that evaluates severe deficits in gait, balance, and mobility. The risk of falling and fear of fall is common among PD individuals and this affects the day to day functioning as well as the quality of life. Early identification of individuals who may be at risk to fall will lead to intervention strategies that can help to with balance issues. The aim of this study was to correlate between Community Balance and Mobility with a battery of outcome measures commonly used to assess balance in Parkinson's disease. METHODS A cross sectional study design; with individuals referred to Outpatient physiotherapy department, diagnosed with idiopathic Parkinson's disease, independently mobile and on a stable drug regimen referred by the neurologist; were screened and recruited by convenience sampling. With written informed consent, demographic data gathered and scales such as Berg Balance scale, Community balance & mobility scale, Functional Reach test and Timed up and go test were administered with an ample amount of rest. RESULTS The results obtained were documented and analysed using Karl Pearson's correlation coefficient. Significant correlation between CB&M and BBS (r = 0.795) was found, CB&M and TUG (r = - 0.755), CB&M and FRT (r = 0.772). CONCLUSION CB&M is a useful measure which integrates items that challenge balance in the community context. It has been used to assess high functioning community dwelling individuals and hence may be apt for individuals with early Parkinson's, since the tasks to be performed in CB&M are challenging and these simulate community level activities where the risk of falls is higher. It may well be a good tool to assess early Parkinson's; their level of balance, community level activity and without need for sophisticated & expensive equipment.

Abstract
Objective and accurate activity identification of physical activities in everyday life is an important aspect in assessing the impact of various post-stroke rehabilitation therapies and interventions. Since post-stroke hemiparesis affects gait and balance in individuals with stroke, activity identification algorithms that consider stroke-specific movement irregularities are needed. While wearable physical activity monitors provide the means to detect activities in the free-living, algorithms using their data are specific to the wear location of the device. This pilot study builds, validates, and compares three machine learning algorithms (linear support vector machine, Random Forest, and RUSBoosted trees) at three popular wear locations (wrist, waist, and ankle) to identify and accurately distinguish mobility-related activities (sitting, standing and walking) in individuals with chronic stroke. A total of 102 minutes of data from two lab visits of three-stroke participants was used to build the classifiers. A 5-fold cross-validation technique was used to validate and compare the accuracy of classifiers. RUSBoosted trees using data from waist and ankle activity monitors, with an accuracy of 99.1%, outperformed other classifiers in detecting three activities of interest.Clinical Relevance- One of the major aims of post-stroke rehabilitation is improving mobility, which may be facilitated by understanding the structure and pattern of everyday mobility through real-world, objective outcomes. Accurate activity identification, as shown in this pilot investigation, is an essential first step before developing objective outcomes for monitoring mobility and balance in everyday life of these individuals.

Abstract
OBJECTIVE The Community Balance and Mobility Scale (CBMS) has been shown to be a valid and reliable outcome measure for evaluating balance and mobility among older adults; however, some items cannot be conducted in all home environments, limiting its use in home-based assessments. The purpose of this study was to evaluate the accuracy and selected measurement properties of a modified 12-item CBMS-Home (8 original items and 4 modified items of the CBMS) feasible for use within the constraints of home assessments for older adults. METHODS Fifty-five people (mean [SD] age = 77.2 [6.0] years) were recruited for this validation study. Participants completed the full original CBMS, CBMS-Home (the modified items of the CBMS), the Functional Reach Test, and Step Test. Principal components analysis, internal consistency, test-retest and intermethod reliability, agreements within and between methods, and criterion validity were calculated. RESULTS Principal components analysis of CBMS and CBMS-Home both revealed 3 similar components and loadings. Bland-Altman and weighted κ analyses revealed that the CBMS-Home demonstrated moderate to almost perfect agreement (weighted κ = 0.45-0.84) with CBMS. The distribution of scores of CBMS-Home were satisfactory, and other results showed excellent test-retest (intraclass correlation coefficient [ICC] = 0.95) and intermethod reliability (ICC = 0.94) and internal consistency (Cronbach α = 0.94). There were no ceiling effects (0%) or floor (1.8%) effects. CBMS-Home demonstrated a low (Spearman ρ = 0.39) and moderate positive (Spearman ρ = 0.63) relationship with the Functional Reach Test and Step Test, respectively. CONCLUSIONS The CBMS-Home has good psychometric properties and provides a useful multidimensional assessment tool. IMPACT A modified version of the CBMS (CBMS-Home) can be confidently used to assess older adults-within their own home-who might have mild balance impairments.

Abstract
BACKGROUND The Six-Spot Step Test (SSST) was originally developed to assess walking ability while challenging balance during walking in patients with multiple sclerosis. It provides more comprehensive information on ambulatory abilities than several existing measures such as the Timed Up & Go test (TUG test), the Functional Gait Assessment, and the Dynamic Gait Index. To assess the advanced balance control ability of stroke survivors, we modified the SSST to serve this purpose. AIM The aim of this study was to expand the current understanding of the psychometric properties of the SSST using healthy older adults and stroke survivors. DESIGN This study adopted an experimental design. SETTING University-affiliated neurorehabilitation laboratory. POPULATION A total of 50 study participants, including 25 chronic stroke survivors and 25 healthy older adults, were recruited from the community. METHODS The SSST was administered to the stroke survivors twice (day 1 & 2) with a 1-week interval. The Fugl-Meyer assessment for the lower extremities (FMA-LE), the Berg Balance scale (BBS), the limit of stability (LOS) test, the Timed Up & Go test (TUG test), and the Chinese version of the Community Integration Measures (CIM-C) were assessed on day 1 by random order. The healthy control group was assessed with the Six-Spot Step Test only on day 1. RESULTS The SSST showed excellent inter-rater, intra-rater, and test-retest reliability (intraclass correlation coefficient>0.95, p<0.001). Significant correlations were found between SSST performance and the FMA-LE results (r=0.517, p<0.05), BBS scores (q r =-0.531, p<0.05), and TUG test scores (r =0.828, p<0.001). The MDC in the mean SSST time for the affected leg and the unaffected leg in stroke survivors was 6.05s. The cutoff time was 10.11s (sensitivity, 80%; specificity, 92%) when kicking obstacles with the affected leg and 10.18s (sensitivity, 80%; specificity, 92%) when kicking obstacles with the unaffected leg. CONCLUSIONS The SSST was a reliable test and showed a significant correlation with FMA-LE scores, BBS scores, and TUG test times in stroke survivors. CLINICAL REHABILITATION IMPACT The SSST can be used to assess the advanced balance control of stroke survivors.

Sensitivity to Change and Responsiveness of the Original and the Shortened Version of the Community Balance & Mobility Scale for Young Seniors. Arch Phys Med Rehabil 2021; 102:2102-2108. [PMID: 33932360 DOI: 10.1016/j.apmr.2021.03.036] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2020] [Revised: 03/04/2021] [Accepted: 03/29/2021] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To examine sensitivity to change and responsiveness of the Community Balance & Mobility Scale (CBM) and shortened CBM (s-CBM) DESIGN: Secondary analysis using data of a randomized controlled trial SETTING: General community PARTICIPANTS: Community-dwelling seniors aged 61-70 years INTERVENTION: Participants underwent 12 months of exercise intervention MAIN OUTCOME MEASURES: CBM and s-CBM. Sensitivity to change was assessed using standardized response mean (SRM), and paired t-tests as appropriate. Responsiveness was assessed using two minimal important difference (MID) estimates. Analyses were conducted for the full sample and for the subgroups 'high-balance' and 'low-balance', divided by median split. RESULTS Young community-dwelling seniors (n=155, 66.2±2.5) were recruited. Inferential statistics revealed a significant CBM (p<0.001) and s-CBM (p<0.001) improvement within the full sample and the subgroups (high-balance: p=0.001, p=0.019; low-balance: p<0.001, p<0.001). CBM and s-CBM were moderately sensitive to change (SRM: 0.48 vs. 0.38) within the full sample. In the high-balance subgroup, moderate SRM values (0.70) were found for the CBM, small values for the s-CBM (0.29). In the low-balance subgroup, moderate SRM values were found for the CBM (0.67), high values for the s-CBM (0.80). For the full sample, CBM and s-CBM exceeded the lower, but not the higher MID value. In the high-balance subgroup, the CBM exceeded both MID values, the s-CBM only the lower. In the low-balance subgroup, CBM and s-CBM exceeded both MID values. CONCLUSIONS The CBM is a suitable tool to detect intervention-related changes of balance and mobility in young, high-performing seniors. Both versions of the CBM scale show good sensitivity to change and responsiveness, particularly in young seniors with low-balance.

Abstract
BACKGROUND Effective and sustainable exercise training methods for improving balance poststroke are needed. OBJECTIVE To evaluate the effect of Baduanjin Qigong for improving balance after stroke. METHODS This was a single-blinded randomized controlled study in which only the assessor was blinded. Fifty-eight people with chronic stroke (mean age: 62.5 ± 11.8 years) were randomly assigned to the experimental (n = 29) or control group (n = 29). The experimental group underwent 8 weeks of supervised Baduanjin training (3 sessions per week). This was followed by home-based practice of the same exercises 3 days a week for another 8 weeks. The control group underwent 2 sessions of supervised conventional fitness training in the first week, followed by home-based exercise practice 3 days a week until the end of week 16. All outcomes were measured at baseline, week 8, and week 16. RESULTS Significantly greater improvements in the Mini-Balance Evaluation Systems Test (Mini-BESTest), composite equilibrium score (Sensory Organization Test), 5 Times Sit to Stand, and Timed Up and Go test were detected at week 8 in the experimental group than in the control group (P < .017). Further improvement in the Mini-BESTest was observed from week 8 to 16 in the experimental group (P < .001). Other outcomes (Limit of Stability, Fall-Efficacy Scale, Modified Barthel Index, Stroke-Specific Quality of Life) showed no significant results. CONCLUSION Baduanjin is effective in improving balance, leg strength, and mobility and is a safe and sustainable form of home-based exercise for people with chronic stroke.

Relationships Between Stepping-Reaction Movement Patterns and Clinical Measures of Balance, Motor Impairment, and Step Characteristics After Stroke. Phys Ther 2021; 101:6145045. [PMID: 33615368 PMCID: PMC8164842 DOI: 10.1093/ptj/pzab069] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2020] [Revised: 09/14/2020] [Accepted: 12/28/2020] [Indexed: 11/14/2022]
Abstract
OBJECTIVE Successful stepping reactions, led by either the paretic or nonparetic leg, in response to a loss of balance are critical to safe mobility poststroke. The purpose of this study was to measure sagittal plane hip, knee, ankle, and trunk kinematics during 2-step stepping reactions initiated by paretic and nonparetic legs of people who had stroke and members of a control group. METHODS Principal component analysis (PCA) was used to reduce the data into movement patterns explaining interlimb coordination of the stepping and stance legs. Correlations among principal components loading scores and clinical measures of balance ability (as measured on the Community Balance and Mobility scale), motor impairment (as measured on the foot and leg sections of the Chedoke-McMaster Stroke Assessment), and step characteristics (length and velocity) were used to examine the effect of stroke on stepping reaction movement patterns. RESULTS The first 5 principal components explained 95.9% of the movement pattern of stepping reactions and differentiated between stepping reactions initiated by paretic legs, nonparetic legs, or the legs of controls. Moderate-strong associations (ρ/r > 0.50) between specific principal component loading scores and clinical measures and step characteristics were dependent on the initiating leg. Lower levels of motor impairment, higher levels of balance ability, and faster and longer steps were associated with stepping reactions initiated by the paretic leg that comprised paretic leg flexion and nonparetic leg extension. Step initiation with the nonparetic leg showed associations between higher scores on clinical measures and movement patterns of flexion in both paretic and nonparetic legs. CONCLUSIONS Movement patterns of stepping reactions poststroke were influenced by the initiating leg. After stroke, specific movement patterns showed associations with clinical measures depending on the initiating leg, suggesting that these movement patterns are important to retraining of stepping reactions. Specifically, use of flexion patterning and assessment of between-leg pattern differentiation may be important aspects to consider during retraining of stepping reactions poststroke. IMPACT Evidence-based interventions targeting balance reactions are still in their infancy. This investigation of stepping reactions poststroke addresses a major gap in research.

Abstract
Socioeconomic reasons post-COVID-19 demand unsupervised home-based rehabilitation and, specifically, artificial ambient intelligence with individualisation to support engagement and motivation. Artificial intelligence must also comply with accountability, responsibility, and transparency (ART) requirements for wider acceptability. This paper presents such a patient-centric individualised home-based rehabilitation support system. To this end, the Timed Up and Go (TUG) and Five Time Sit To Stand (FTSTS) tests evaluate daily living activity performance in the presence or development of comorbidities. We present a method for generating synthetic datasets complementing experimental observations and mitigating bias. We present an incremental hybrid machine learning algorithm combining ensemble learning and hybrid stacking using extreme gradient boosted decision trees and k-nearest neighbours to meet individualisation, interpretability, and ART design requirements while maintaining low computation footprint. The model reaches up to 100% accuracy for both FTSTS and TUG in predicting associated patient medical condition, and 100% or 83.13%, respectively, in predicting area of difficulty in the segments of the test. Our results show an improvement of 5% and 15% for FTSTS and TUG tests, respectively, over previous approaches that use intrusive means of monitoring such as cameras.

Abstract
BACKGROUND AND PURPOSE Considering the multifactorial nature and the often-grave consequences of falls in people with chronic stroke (PwCS), determining measurements that best predict fall risk is essential for identifying those who are at high risk. We aimed to determine measures from the domains of the International Classification of Functioning, Disability and Health (ICF) that can predict laboratory-induced slip-related fall risk among PwCS. METHODS Fifty-six PwCS participated in the experiment in which they were subjected to an unannounced slip of the paretic leg while walking on an overground walkway. Prior to the slip, they were given a battery of tests to assess fall risk factors. Balance was assessed using performance-based tests and instrumented measures. Other fall risk factors assessed were severity of sensorimotor impairment, muscle strength, physical activity level, and psychosocial factors. Logistic regression analysis was performed for all variables. The accuracy of each measure was examined based on its sensitivity and specificity for fall risk prediction. RESULTS Of the 56 participants, 24 (43%) fell upon slipping while 32 (57%) recovered their balance. The multivariate logistic regression analysis model identified dynamic gait stability, hip extensor strength, and the Timed Up and Go (TUG) score as significant laboratory-induced slip-fall predictors with a combined sensitivity of 75%, a specificity of 79.2%, and an overall accuracy of 77.3%. DISCUSSION AND CONCLUSIONS The results indicate that fall risk measures within the ICF domains-body, structure, and function (dynamic gait stability and hip extensor strength) and activity limitation (TUG)-could provide a sensitive laboratory-induced slip-fall prediction model in PwCS.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A323).

Abstract
OBJECTIVE A loss of balance poststroke from externally induced perturbations or during voluntary movements is often recovered by stepping. The purpose of this study was to characterize stepping behavior during lateral induced waist-pull perturbations and voluntary steps in community-dwelling fallers and nonfallers with chronic stroke. METHODS This study used a cohort design. Thirty participants >6 months poststroke were exposed to 24 externally triggered lateral waist-pull perturbations and 20 voluntary steps. Balance tolerance limit (BTL) (transition from single to multiple steps) and first step type were determined for the waist-pull perturbations. Step parameters of initiation time, velocity, first step length, and clearance were calculated at and above BTL and for the voluntary steps. Hip abductor/adductor torque, foot cutaneous sensation, and self-reported falls that occurred 6 months prior were evaluated. RESULTS Twelve participants were classified retrospectively as fallers and 18 as nonfallers. Fallers had a reduced BTL and took more medial first steps than nonfallers. Above BTL, no between-group differences were found in medial steps. At BTL, the nonparetic step clearance was reduced in fallers. Above BTL, fallers took longer to initiate a paretic and nonparetic step and had a reduced nonparetic step length and clearance compared with nonfallers. There was a between-group difference in step initiation time for voluntary stepping with the paretic leg (P < .05). Fallers had a reduced paretic abductor torque and impaired paretic foot cutaneous sensation. CONCLUSION A high fall rate poststroke necessitates effective fall prevention strategies. Given that more differences were found during perturbation-induced stepping between fallers and nonfallers, further research assessing perturbation-induced training on reducing falls is needed. IMPACT Falls assessments should include both externally induced perturbations along with voluntary movements in determining the fall risk.

Abstract
Background: Limited studies have examined the responsiveness of the Sitting Balance Scale (SBS) and Function in Sitting Test (FIST). No studies have investigated the psychometric properties of these tools in skilled nursing facilities.Objective: The purposes of the study were (1) to examine responsiveness of the SBS and FIST, in people with stroke, receiving rehabilitation in skilled nursing facilities; and (2) to estimate the MDC and MCID of these scales.Methods: Forty participants completed the FIST, SBS, and Barthel Index (BI) at admission and discharge. Internal responsiveness of the FIST and SBS was measured using Effect Size (ES) and Standardized Response Mean (SRM). Examining the association between the difference in scores on the SBS or FIST and the difference in scores on the BI determined external responsiveness. MDC and MCID were estimated for both measures.Results: The ES and the SRM for both scales were large (1.01-2.30) indicating excellent internal responsiveness. Both scales demonstrated satisfactory external responsiveness, showing good association with change in BI scores (p < .01). MDC90 of the SBS and the FIST were 2.3 and 3.9, respectively. Anchor-based MCID estimates were 4.5 and 3.5, and distribution-based were 3.5 and 4.8 for the SBS and FIST, respectively.Conclusions: Both scales demonstrate sufficient responsiveness in the skilled nursing setting. Our findings suggest a change of 5 on the SBS and 4 on the FIST are clinically important, and clinicians may use these values to assess patient progress.

Abstract
INTRODUCTION Individuals with stroke discharged from inpatient rehabilitation units (IRUs) are at increased risk for falls. In IRUs, standardized outcome measures (SOMs) have been used to predict falls, but the results have been mixed. OBJECTIVE To examine the relationship between SOMs and the risk of falls in individuals with stroke within 6 months of discharge from an IRU. DESIGN Prospective cohort study with 6-month follow-up. SETTING IRU that was part of a large, urban academic medical center. PARTICIPANTS Individuals with stroke who underwent rehabilitation. MAIN OUTCOME MEASURES Self-reported falls within 6 months of discharge. RESULTS The study included 105 participants who were discharged to their homes after inpatient rehabilitation and who responded to a 6-month follow-up (57% response rate) phone call. Twenty-nine participants (28%) reported falling. Significant odds ratios (ORs), adjusted for age, sex, and stroke severity, were found for the following measures: Berg Balance Scale (OR 0.95, 95% confidence interval [CI] 0.92-0.99), Activity Measure for Post-Acute Care basic mobility (OR 0.89, 95% CI 0.81-0.97), Motricity Index (OR 0.96, 95% CI 0.94-0.98), Functional Independence Measure mobility subscale (OR 0.89, 95% CI 0.80-0.98), and Trunk Control Test (OR 0.97, 95% CI 0.95-0.99). Areas under the curve ranged from .64 to .71. In samples of 82 to 90 patients who could complete the tests, gait speed, the Functional Reach Test, the 6-minute Walk Test, and Timed Up and Go did not result in significant ORs. CONCLUSIONS At discharge, SOMs were associated with the odds of falls within 6 months. The multifactorial nature of falls will continue to make prediction challenging but SOMs can be helpful. Lower extremity strength deserves more attention as a risk factor.

Abstract
BACKGROUND AND PURPOSE High-functioning stroke survivors with mild to moderate motor impairments show greater functional autonomy in activities of daily living, and often return to work or prior activities. Increased functional independence necessitates dexterous use of hands to execute tasks such as typing, using a phone, and driving. Despite the absence of any pronounced motor impairments, high-functioning individuals with stroke report challenges in performing skilled manual tasks. Two prominent motor deficits that limit functional performance after stroke are decline in strength and force control. Here, we quantify the deficits in fine motor dexterity in high-functioning stroke survivors and determine the relative contribution of strength and force control to fine motor dexterity. METHODS Fifteen high-functioning participants with stroke (upper-limb Fugl-Meyer score ≥43/66) and 15 controls performed following tasks with the paretic and non-dominant hands respectively: i) Nine-hole peg pest, ii) maximum voluntary contraction and iii) dynamic force tracking with isometric finger flexion. RESULTS High-functioning stroke participants required greater time to complete the pegboard task, showed reduced finger strength, and increased force variability relative to the controls. Importantly, the time to complete pegboard task in high-functioning stroke participants was explained by finger force variability, not strength. DISCUSSION AND CONCLUSIONS High-functioning stroke survivors show persistent deficits in fine motor dexterity, finger strength, and force control. The ability to modulate forces (control) contributes to fine motor dexterity in high-functioning stroke survivors. Interventions to improve fine motor dexterity in these individuals should include the assessment and training of force control.

Abstract
Individuals with knee osteoarthritis (OA) commonly demonstrate impaired postural control. We aimed to systematically review psychometric properties of tests that assess postural control in people with knee OA and secondly, to determine domains of postural control measured by these tests. PubMed, CINAHL, Embase and Web of Science databases were searched to January 2019. Two independent review authors screened references according to eligibility criteria. The Consensus-based Standards for the selection of health Measurement Instruments were used to evaluate study methodological quality. Postural control tests identified from included studies were assessed to determine postural control constructs using the Systems Framework for Postural Control identifying nine domains. Following the screening of 2643 references, five cross-sectional studies and one longitudinal study (n = 408) were included. Four studies evaluated reliability, validity or responsiveness of three clinical measures: Community Balance and Mobility Scale, Star Excursion Balance Test and Tinetti Performance Oriented Mobility Assessment. Two assessed reliability or validity of a force platform. Results showed that evidence for reliability, validity and responsiveness of all these postural measures is limited. The most common domain of postural control assessed was 'static stability'. No study used measures that evaluated all nine postural control domains. Our results highlight limited investigation of psychometric properties specific to postural control in knee OA. The few existing ones have limitations regarding psychometric robustness and completeness regarding different domains of postural control. Future research should focus on verifying the quality of existing tools to evaluate postural control in knee OA for research and clinical purposes.

Abstract
BACKGROUND AND PURPOSE Therapeutic exercise improves balance and walking ability in individuals after stroke. The extent to which motor planning improves with therapeutic exercise is unknown. This case series examined how outpatient physical therapy affects motor planning and motor performance for stepping. CASE DESCRIPTION Individuals poststroke performed self-initiated stepping before (baseline), after (postintervention), and 1 month after (retention) intervention. Amplitude and duration of the movement-related cortical potential (MRCP) was measured using an electroencephalograph from the Cz electrode. Electromyography (EMG) of biceps femoris (BF) was collected. Additionally, clinical measures of motor impairment and function were evaluated at all 3 time points by a blinded assessor. INTERVENTION Two types of outpatient physical therapy were performed for 6 weeks: CONVENTIONAL (n = 3) and FAST (n = 4, Fast muscle Activation and Stepping Training). OUTCOMES All 7 participants reduced MRCP duration, irrespective of the type of physical therapy. The MRCP amplitude and BF EMG onset changes were more variable. Clinical outcomes improved or were maintained for all participants. The extent of motor impairment was associated with MRCP amplitude. DISCUSSION Changes in MRCP duration suggest that outpatient physical therapy may promote neuroplasticity of motor planning of stepping movements after stroke; however, a larger sample is needed to determine whether this finding is valid.This case series suggests motor planning for initiating stepping may improve after 6 weeks of outpatient physical therapy for persons with stroke.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A307).

Utility of Dynamic Balance Measurements in Discriminating Community Ambulation Levels Among Individuals with Stroke: A Cross-sectional Study. J Stroke Cerebrovasc Dis 2020; 29:104603. [PMID: 31932210 DOI: 10.1016/j.jstrokecerebrovasdis.2019.104603] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2019] [Revised: 11/25/2019] [Accepted: 12/12/2019] [Indexed: 12/01/2022] Open
Abstract
OBJECTIVE To examine the association between dynamic balance measurements and community ambulation levels among individuals with chronic stroke. METHODS This cross-sectional study was performed in 2-day care facilities for older adults located in urban areas. Forty-seven community-dwelling poststroke adults who could walk independently were participated. Community ambulation performance was assessed using the Functional Ambulation Classification of the Hospital at Sagunto (FACHS). Dynamic balance and mobility were measured with the Mini-Balance Evaluation Systems Test (Mini-BESTest), the Timed Up and Go (TUG) test, and 10 m maximum walking speed. RESULTS Participants were classified into 3 groups according to FACHS scores: household (n = 15), neighborhood (n = 19), and community walkers (n = 13). Neighborhood and community walkers scored significantly higher on the Mini-BESTest and had a shorter TUG test time than household walkers. Community walkers had a significantly faster walking speed than household walkers, whereas neighborhood walkers did not have a faster walking speed than household walkers. Ordinal logistic regression analyses revealed the Mini-BESTest score (odds ratio [OR] 1.24; 95% confidence interval [CI]: 1.07-1.44) and the TUG test time (OR .91; 95% CI: .85-.98) were significantly associated with ambulation levels after adjusting for confounders. CONCLUSIONS Dynamic balance measurement tools may have better responsiveness in detecting community ambulation levels among individuals with chronic stroke than walking speed.

Abstract
The purpose of this pilot randomized controlled trial is to assess the feasibility and impact of a triweekly 12-week yoga intervention among people living with HIV (PLWH). Additional objectives included evaluating cognition, physical function, medication adherence, health-related quality of life (HRQoL), and mental health among yoga participants versus controls using blinded assessors. We recruited 22 medically stable PLWH aged ≥35 years. A priori feasibility criteria were ≥70% yoga session attendance and ≥70% of participants satisfied with the intervention using a postparticipation questionnaire. Two participants withdrew from the yoga group. Mean yoga class attendance was 82%, with 100% satisfaction. Intention-to-treat analyses (yoga n = 11, control n = 11) showed no within- or between-group differences in cognitive and physical function. The yoga group improved over time in HRQoL cognition (P = .047) with trends toward improvements in HRQoL health transition (P =.063) and depression (P = .055). This pilot study provides preliminary evidence of feasibility and benefits of yoga for PLWH.

Abstract
Abstract
Introduction
The objective of this study was to determine the utility of the Community Balance and Mobility scale (CB&M) among service members presenting with mild traumatic brain injury (mTBI), to compare the results against well-established balance assessments, and to find a new military-specific CB&M cut score to help differentiate those with and without mTBI.
Materials and Methods
The setting was a 4-week, intensive-outpatient, interdisciplinary program for active duty service members with mTBI. This was a nonrandomized, cross-sectional design that compared multiple measures between two groups: active duty service members with (n = 45) and without (n = 45) mTBI. The assessments, including the Activities-Specific Balance Confidence Scale, gait speed (comfortable and fast), the Functional Gait Assessment, and the CB&M, were provided to both sample groups.
Results
The mTBI group performed significantly worse (P ≤ 0.01) across all measures. A higher cut score for the CB&M of 81.5 is suggested. The CB&M demonstrated the best sensitivity (78%) and specificity (91%) ratio, as well as the largest effect size and area under the curve(0.92).
Conclusion
All objective measures distinguish participants with mTBI from controls, ranging from fair to excellent. The recommended CB&M cut score of 81.5 allows for good variance, standard deviation, and reduced risk of ceiling or floor effects. Further examination of the recommended CB&M cut score is warranted for use in the mTBI civilian populations.

Abstract
Supplemental Digital Content is Available in the Text. Background: Use of outcome measures (OMs) in adult neurologic physical therapy is essential for monitoring changes in a patient's status over time, quantifying observations and patient-reported function, enhancing communication, and increasing the efficiency of patient care. OMs also provide a mechanism to compare patient and organizational outcomes, examine intervention effectiveness, and generate new knowledge. This clinical practice guideline (CPG) examined the literature related to OMs of balance, gait, transfers, and patient-stated goals to identify a core set of OMs for use across adults with neurologic conditions and practice settings. Methods: To determine the scope of this CPG, surveys were conducted to assess the needs and priorities of consumers and physical therapists. OMs were identified through recommendations of the Academy of Neurologic Physical Therapy's Evidence Database to Guide Effectiveness task forces. A systematic review of the literature on the OMs was conducted and additional OMs were identified; the literature search was repeated on these measures. Articles meeting the inclusion criteria were critically appraised by 2 reviewers using a modified version of the COnsensus-based Standards for the selection of health Measurement INstruments. (COSMIN) checklist. Methodological quality and the strength of statistical results were determined. To be recommended for the core set, the OMs needed to demonstrate excellent psychometric properties in high-quality studies across neurologic conditions. Results/Discussion: Based on survey results, the CPG focuses on OMs that have acceptable clinical utility and can be used to assess change over time in a patient's balance, gait, transfers, and patient-stated goals. Strong, level I evidence supports the use of the Berg Balance Scale to assess changes in static and dynamic sitting and standing balance and the Activities-specific Balance Confidence Scale to assess changes in balance confidence. Strong to moderate evidence supports the use of the Functional Gait Assessment to assess changes in dynamic balance while walking, the 10 meter Walk Test to assess changes in gait speed, and the 6-Minute Walk Test to assess changes in walking distance. Best practice evidence supports the use of the 5 Times Sit-to-Stand to assess sit to standing transfers. Evidence was insufficient to support use of a specific OM to assess patient-stated goals across adult neurologic conditions. Physical therapists should discuss the OM results with patients and collaboratively decide how the results should inform the plan of care. Disclaimer: The recommendations included in this CPG are intended as a guide for clinicians, patients, educators, and researchers to improve rehabilitation care and its impact on adults with neurologic conditions. The contents of this CPG were developed with support from the APTA and the Academy of Neurologic Physical Therapy (ANPT). The Guideline Development Group (GDG) used a rigorous review process and was able to freely express its findings and recommendations without influence from the APTA or the ANPT.

Abstract
BACKGROUND Few reports have examined the relationship between balance ability and walking ability in people with transfemoral amputation using the Berg Balance Scale. OBJECTIVES To assess the construct validity (known groups discrimination, convergent validity, and floor/ceiling effects) of Berg Balance Scale for people with transfemoral amputation. STUDY DESIGN Cross-sectional study. METHODS Thirty people with transfemoral amputation participated (age: 54 ± 19 years; range: 18-78 years). Outcome measures (Berg Balance Scale, Timed Up & Go test, Six-Minute Walk Test, and use of ambulatory aids) were compared between the groups requiring and not requiring ambulatory aids by the Mann-Whitney U test, Student's t-test or Welch's t-test. Correlations were assessed using Spearman's rank correlation coefficients and age-corrected Spearman's partial rank correlation coefficients. RESULTS The group using ambulatory aids had a significantly lower Berg Balance Scale score (41 ± 5 vs 52 ± 3). Berg Balance Scale score was correlated with Timed Up & Go test, use of aids, and Six-Minute Walk Test using Spearman's rank correlation coefficients (r =-0.85, p < 0.0001; r =-0.82, p < 0.0001; r = 0.81, p < 0.0001) and age-corrected partial rank correlation coefficients (r =-0.66, p < 0.0001; r =-0.56, p = 0.0017; r = 0.57, p = 0.0012). No ceiling effect of Berg Balance Scale was observed. CONCLUSIONS Balance ability in people with transfemoral amputation could be evaluated using Berg Balance Scale and is correlated with walking ability. CLINICAL RELEVANCE In clinical practice, using Berg Balance Scale for people with transfemoral amputation may adequately enable us to discriminate different groups based on walking ability from the perspective of balance ability. When walking ability is evaluated as low, the improvement of walking ability may be evaluated by Berg Balance Scale improvement during rehabilitation.

Abstract
Background: With limited inpatient rehabilitation (IR) length of stays for patients post-stroke, it is critical to maximize the effectiveness of interventions to address their balance and gait speed deficits. Backward walking (BW) is an emerging training approach; however, its application to patient populations consistent with those in IR is limited. Objectives: To describe the effects of an additional BW training program to standard IR care on balance, walking ability and fall-risk in a heterogenic caseload of adults <2 weeks post-stroke with a broad range of lesion locations and physical sequelae. Methods: Eight patients with first-time stroke (5 male; average age 66.5 ± 11.7 years; average stroke onset 7.6 ± 1.6 days; 6 right hemiparesis) participated in 10-daily sessions that included 20 min of over ground BW training for each session, in addition to standard IR. Standard outcome measures were used to assess balance, walking ability and fall-risk at admission and post-intervention. Results: All eight patients demonstrated improvements in all outcomes with a clinically meaningful increase in forward walking speed, as measured by 10MWT. Four participants exceeded fall-risk cut-off scores for all balance-related outcome measures. Conclusions: In a diverse patient population early after stroke, individuals successfully participated in an additional BW training program. Despite the patients' acuity and severe impairments in walking, significant gains in balance and walking function were noted. This program may be useful in improving outcomes with patient characteristics commonly seen in IR.

Abstract
PURPOSE Many patients participating in cardiac rehabilitation (CR) programs have decreased balance. This is a concern, as it may affect their ability to optimally perform physical exercise in CR and thus decrease CR efficacy. Despite this concern, balance is typically not assessed as part of CR intake. This may be attributable to the fact that a suitable balance assessment tool has not been identified for higher-functioning CR patients. A potential solution to this issue is using the Community Balance and Mobility Scale (CBMS), which has been used to assess balance in higher-functioning clinical populations; however, its use in a CR population has never been investigated. Therefore, the purpose of this study was to determine the reliability and validity of the CBMS for assessing balance in CR patients. METHODS Fifty-three participants were recruited from local CR programs to perform the CBMS. Dynamic posturography was also measured in a subset of participants (n = 31) using the Limits of Stability (LOS) test. RESULTS Analysis of CBMS scores revealed that the mean CBMS score was 61.9 ± 16.2 (out of 96) and that no floor or ceiling effects were observed for any participants. CBMS scores were significantly correlated with the LOS results (0.41-0.53). Interrater reliability between novice and expert testers was strong (r = 0.95), with all differences falling within the 95% limits of agreement. CONCLUSION Overall, these results suggest that the CBMS is a valid tool to measure balance in CR patients and can be reliably administered by health care professionals with minimal training.

Abstract
Background Virtual reality training (VRT) uses computer software to track a user’s movements and allow him or her to interact with a game presented on a television screen. VRT is increasingly being used for the rehabilitation of arm function, balance and walking after stroke. Patients often require ongoing therapy post discharge from inpatient rehabilitation. Outpatient therapy may be limited or inaccessible due to waiting lists, transportation issues, distance etc.; therefore, home-based VRT could provide the required therapy in a more convenient and accessible setting. The objectives of this parallel randomized feasibility trial are to determine (1) the feasibility of using VRT in the home post stroke and (2) the feasibility of a battery of quantitative and qualitative outcome measures of stroke recovery. Methods Forty patients who can stand for at least 2 min and are soon to be discharged from inpatient or outpatient rehabilitation post stroke are being recruited in Ottawa, Canada and being randomized to control and experimental groups. Participants in the experimental group use home-based VRT to do rehabilitative exercises for standing balance, stepping, reaching, strengthening and gentle aerobic fitness. Control group participants use an iPad with apps selected to rehabilitate cognition, hand fine motor skills and visual tracking/scanning. Both groups are instructed to perform 30 min of exercise 5 days a week for 6 weeks. VRT intensity and difficulty are monitored and adjusted remotely. Weekly telephone contact is made with all participants. Ability to recruit participants, ability to handle the technology and learn the activities, compliance, safety, enjoyment, perceived efficacy and cost of program delivery will be assessed. A battery of assessments of standing balance, gait and community integration will be assessed for feasibility of completion within this population and potential for improvement following the intervention. Effect sizes will be calculated. Discussion The results of this study will be used to support the creation of a definitive randomized controlled trial on the efficacy of home-based VRT for rehabilitation post stroke. Trial Registration ClinicalTrials.gov, NCT03261713. Registered on 21 August 2017. Registration amended on 1 June 2018 to decrease enrollment from 40 to 20 due to a cut in study funding and difficulty recruiting participants.

Abstract
BACKGROUND Stepping is critical for responding to perturbations, whether externally induced or self-initiated. Falls post-stroke is equally likely to happen from either mechanism. The objective of the study was, to examine lateral stepping performance during waist-pull induced reactive steps and voluntary choice reaction time steps in chronic stroke and controls. METHODS In this cross-sectional study participants with chronic stroke (N = 10) and age- and gender-matched controls (N = 10) performed reactive and voluntary lateral steps. Step initiation time, global step length, step clearance, and step velocity were calculated. Other measures for reactive step included, Balance tolerance limit (perturbation magnitude when recovery transitioned from single to multiple steps), and step type. The Community Balance & Mobility Scale, and hip abductor and adductor isokinetic asymmetry torque ratio were assessed. RESULTS The paretic and non-paretic leg were combined since step characteristics did not differ. Step (voluntary vs. reactive) by group (stroke vs. controls) was significant for step initiation time. The stroke group took longer initiating a voluntary step (P = 0.004). Reactive and voluntary steps were executed slower (P = 0.041), with a reduced step length (P = 0.028) by the stroke group. The stroke group had a lower balance tolerance limit (P = 0.01) and took reactive medial steps more frequently (P = 0.001). The Community Balance & Mobility Scale (P > 0.001), and hip abductor and adductor asymmetry torque ratio (P > 0.001; P = 0.015) was reduced in the stroke group. SIGNIFICANCE Our findings indicate individuals post-stroke are slower initiating and executing reactive and voluntary steps. Though the reactive step timing is less impaired, this may be a method for enhancing faster voluntary movements and training reactive balance.

Abstract
Background Despite lower mortality rates due to combination antiretroviral therapy, people living with HIV (PLWH) are grappling with increasingly complex health issues, including cognitive impairments in areas such as memory, attention, processing speed, and motor function. Yoga has been shown to be an effective form of exercise and mindfulness-based stress reduction for many clinical populations. However, no randomized trials have evaluated the impact of yoga on cognitive and physical function among PLWH. Objective The aim of this pilot randomized trial was to determine the feasibility of a yoga intervention to lay the groundwork for a full-scale, multisite, community-based trial for PLWH. Specific objectives are to (1) assess the feasibility of study protocol and procedures, (2) compare cognition in the yoga group with the usual care control group after 12 weeks of the intervention in PLWH, and (3) compare the effects of the 12-week yoga intervention versus control on balance, walking speed, physical activity, mental health, medication adherence, and quality of life among PLWH. Methods We propose a pilot randomized trial with 2 parallel groups (yoga versus control). We will recruit 25 PLWH (>35 years) from community and health organizations in Halifax, Canada. After baseline assessment with blinded assessors, participants will be randomly assigned to the yoga or control group, using a random computer generator. Participants in the yoga group will engage in supervised 60-min group-based yoga sessions 3 times a week for 12 weeks at a yoga studio. Participants in the control group will maintain their current physical activity levels throughout the study. Results As per the Consolidated Standards of Reporting Trials extension for pilot studies, means of all outcomes, mean change, and 95% CIs will be calculated for each group separately. Two-tailed independent t tests and Fisher exact tests will be used to compare groups at baseline. We will analyze quantitative postintervention questionnaire responses using Chi-square tests, and open-ended responses will be analyzed thematically. Intention-to-treat and per-protocol analyses will be used to analyze secondary variables. Changes in outcome variables will be examined between groups and within groups. Effect sizes will be reported for each outcome. A priori adherence and satisfaction criteria will be met if participants attend >70% of the yoga sessions and if >70% of the participants are satisfied with the intervention as determined by a postparticipation questionnaire. Study enrollment began in January 2018, with results expected for October 2019.

Abstract
Purpose: Our purpose was to estimate a threshold value for change for the six dimensions of the Impairment Inventory of the Chedoke-McMaster Stroke Assessment and the confidence in labelling a person as having improved or not. Method: Secondary analysis of two data sets, previously reported by two research teams, consisted of two statistical analyses. The first analysis used a multiple of the standard error of measurement to calculate the threshold value for change for the six dimensions. The second analysis used the diagnostic test method to calculate a threshold improvement value and the confidence a clinician had in labelling a person as having improved or not on the leg, foot, and postural control dimensions. Results: The threshold value for change was determined to be 1 impairment point (i.e., stage) for the arm, hand, leg, foot, and postural control dimensions and 2 impairment points for the shoulder pain dimension. The positive predictive values associated with the leg, foot, and postural control dimensions were 74%, 59%, and 65%, respectively. Conclusions: Clinicians can use a change of 1 impairment point for the arm, hand, leg, foot, and postural control dimensions and a change of 2 impairment points for the shoulder pain dimension to identify true change in a patient's motor recovery.

Abstract
Posture and movement planning, preparation, and execution of a goal-directed reaching movement are impaired in individuals with stroke. No studies have shown whether the deficits are generally impaired or are specific to the lesioned hemisphere/paretic arm. This study utilized StartReact (SR) responses elicited by loud acoustic stimuli (LAS) to investigate the preparation and execution of anticipatory postural adjustments (APAs) and reach movement response during both paretic and nonparetic arm reaching in individuals with stroke and in age-matched healthy controls. Subjects were asked to get ready after receiving a warning cue and to reach at a "go" cue. An LAS was delivered at -500, -200, and 0 ms relative to the go cue. Kinetic, kinematic, and electromyographic data were recorded to characterize APA-reach movement responses. Individuals with stroke demonstrated systemwide deficits in posture and in movement planning, preparation, and execution of APA-reach sequence as shown by significant reduction in the incidence of SR response and impaired APA-reach performance, with greater deficits during paretic arm reaching. Use of trunk compensation strategy as characterized by greater involvement of trunk and pelvic rotation was utilized by individuals with stroke during paretic arm reaching compared with nonparetic arm reaching and healthy controls. Our findings have implications for upper extremity and postural control, suggesting that intervention should include training not only for the paretic arm but also for the nonparetic arm with simultaneous postural control requirements to improve the coordination of the APA-reach performance and subsequently reduce instability while functional tasks are performed during standing. NEW & NOTEWORTHY Our study is the first to show that nonparetic arm reaching also demonstrates impairment in posture and movement planning, preparation, and execution when performed during standing by individuals with stroke. In addition, we found compensatory trunk and pelvic rotations were used during a standing reach task for the paretic arms. The findings have clinical implications for upper extremity and postural rehabilitation, suggesting that training should include the nonparetic arms and incorporate simultaneous postural control demands.

Abstract
BACKGROUND Wearable powered exoskeletons provide intensive overground gait training with patient's active participation: these features promote a successful active motor relearning of ambulation in stroke survivors. AIM The aim of this study was to investigate the feasibility and the clinical effects of an overground exoskeleton-assisted gait training (OEAGT) in subacute stroke patients. DESIGN Prospective, pilot pre-post, open label, non-randomized experimental study. SETTING Four Italian neurological rehabilitation centers. POPULATION Forty-eight subacute stroke patients were enrolled. Two patients dropped out because of medical problems. Data analysis was conducted on 46 subjects (56.84±14.29 years; 27 male; 29 ischemic; 24 left hemiparesis). METHODS Patients underwent 15±2 sessions (60 min/session, 3-5 times/week) of OEAGT. Clinical and gait assessments were performed at the beginning (T1) and at the end (T2) of the training period: modified Barthel Index (BI), modified Ashworth Scale at Hip (MAS-H), Knee (MAS-K), and Ankle (MAS-A) level, Motricity Index (MI), Trunk Control Test (TCT), Functional Ambulation Classification (FAC), Walking Handicap Scale (WHS), 10-Meter Walking Test (10MWT), 6-Minute Walking Test (6mWT), Timed Up-and-Go test (TUG). The Technology Acceptance Model (TAM) questionnaire evaluated the acceptance of OEAGT by patients. Data stratification was performed using the time post the acute event and the onset of rehabilitation treatment, and the MI at T1. Wilcoxon's test (P<0.05) was used. RESULTS All clinical scales significantly improved at T2; no statistically significant changes were reported for MAS-H, MAS-K, MAS-A. The 69.57% patients were able to walk at T1; 17.39% were not able to walk at T1 but regained ambulation at T2; and 13.04% were not able to walk at either T1 or T2. The ambulant patients showed a statistical improvement in speed measured during the 10MWT and in the distance covered over a time of 6 minutes (6mWT). The results from the TAM questionnaire showed that all subjects perceived the OEAGT positively. The data stratification analysis suggests that the OEAGT does not have any restriction of use. CONCLUSIONS The OEAGT improved the clinical and gait outcomes in subacute patients. Randomized studies on larger samples are needed to confirm these data and to assess the efficacy of OEAGT. CLINICAL REHABILITATION IMPACT Introduce innovative rehabilitation strategies based on customized OEAGT.

Abstract
Walking can be exceedingly complex to analyze due to highly nonlinear multi-body dynamics, nonlinear relationships between muscle excitations and resulting muscle forces, dynamic coupling that allows muscles to accelerate joints and segments they do not span, and redundant muscle control. Walking requires the successful execution of a number of biomechanical functions such as providing body support, forward propulsion and balance control, with specific muscle groups contributing to their execution. Thus, muscle injury or neurological impairment that affects muscle output can alter the successful execution of these functions and impair walking performance. The loss of balance control in particular can result in falls and subsequent injuries that lead to the loss of mobility and functional independence. Thus, it is important to assess the mechanisms used to control balance in clinical populations using reliable methods with the ultimate goal of improving rehabilitation outcomes. In this review, we highlight common clinical and laboratory-based measures used to assess balance control and their potential limitations, show how these measures have been used to analyze balance in several clinical populations, and consider the translation of specific laboratory-based measures from the research laboratory to the clinic.

Abstract
The ability to actively suppress, or gate, irrelevant sensory information is required for safe and efficient walking in sensory-rich environments. Both motor attention and motor planning alter somatosensory evoked potentials (SEPs) in healthy adults. This study's aim was to examine the effect of motor attention on processing of irrelevant somatosensory information during plantar flexion motor planning after stroke. Thirteen healthy older adults and 11 individuals with stroke participated. Irrelevant tibial nerve stimulation was delivered while SEPs were recorded over Cz, overlaying the leg portion of the sensorimotor cortex at the vertex of the head. Three conditions were tested in both legs: (1) Rest, (2) Attend To, and (3) Attend Away from the stimulated limb. In conditions 2 and 3, relevant vibration cued voluntary plantar flexion movements of the stimulated (Attend To) or non-stimulated (Attend Away) leg. SEP amplitudes were averaged during motor planning per condition. Individuals with stroke did not show attention-mediated gating of the N40 component associated with irrelevant somatosensory information during motor planning. It may be that dysfunction in pathways connecting to area 3b explains the lack of attention-mediated gating of the N40. Also, attention-mediated gating during motor planning explained significant and unique variance in a measure of community balance and mobility combined with response time. Thus, the ability to gate irrelevant somatosensory information appears important for stepping in both older adults and after stroke. Our data suggest that therapies that direct motor attention could positively impact walking after stroke.

Abstract
Purpose: To investigate the prevalence and distribution of lower limb somatosensory impairments in community dwelling chronic stroke survivors and examine the association between somatosensory impairments and walking, balance, and falls. Methods: Using a cross sectional observational design, measures of somatosensation (Erasmus MC modifications to the (revised) Nottingham Sensory Assessment), walking ability (10 m walk test, Walking Impact Scale, Timed "Get up and go"), balance (Functional Reach Test and Centre of Force velocity), and falls (reported incidence and Falls Efficacy Scale-International), were obtained. Results: Complete somatosensory data was obtained for 163 ambulatory chronic stroke survivors with a mean (SD) age 67(12) years and mean (SD) time since stroke 29 (46) months. Overall, 56% (n = 92/163) were impaired in the most affected lower limb in one or more sensory modality; 18% (n = 30/163) had impairment of exteroceptive sensation (light touch, pressure, and pin-prick), 55% (n = 90/163) had impairment of sharp-blunt discrimination, and 19% (n = 31/163) proprioceptive impairment. Distal regions of toes and foot were more frequently impaired than proximal regions (shin and thigh). Distal proprioception was significantly correlated with falls incidence (r = 0.25; p < 0.01), and centre of force velocity (r = 0.22, p < 0.01). The Walking Impact Scale was the only variable that significantly contributed to a predictive model of falls accounting for 15-20% of the variance. Conclusion: Lower limb somatosensory impairments are present in the majority of chronic stroke survivors and differ widely across modalities. Deficits of foot and ankle proprioception are most strongly associated with, but not predictive, of reported falls. The relative contribution of lower limb somatosensory impairments to mobility in chronic stroke survivors appears limited. Further investigation, particularly with regard to community mobility and falls, is warranted. Implications for Rehabilitation Somatosensory impairments in the lower limb were present in approximately half of this cohort of chronic stroke survivors. Tactile discrimination is commonly impaired; clinicians should include an assessment of discriminative ability. Deficits of foot and ankle proprioception are most strongly associated with reported falls. Understanding post-stroke lower limb somatosensory impairments may help inform therapeutic strategies that aim to maximise long-term participation, minimise disability, and reduce falls.
