The Effect of ICF-Core Set-Based Occupational Therapy Interventions on the Function and Satisfaction of Individuals with Chronic Stroke: A Randomized Clinical Trial. Occup Ther Health Care 2024; 38:177-195. [PMID: 36036175 DOI: 10.1080/07380577.2022.2114612] [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: 11/15/2021] [Revised: 07/23/2022] [Accepted: 08/14/2022] [Indexed: 06/15/2023]
Abstract
Stroke can affect all aspects of a person's health and functioning. Therefore, it is important occupational therapists, have a comprehensive understanding of various levels of function and the factors affecting function. The ICF (International Classification of Functioning, Disability, and Health) and the selections of ICF categories or Core Sets relevant for people with a specific health condition, offer a model for intervention. This study aimed to investigate the effect of ICF-CS-based occupational therapy interventions on the function and satisfaction of individuals with chronic stroke. This study was designed as a randomized, single-blind, parallel-group clinical trial. Twenty-five patients with stroke were randomly assigned to the control group (which received traditional occupational therapy) or the treatment group (Stroke ICF-CS based occupational therapy). Patients were evaluated before and after the intervention (two months, three sessions per week, 45 minutes each session), as well as two weeks after the end of the intervention, using Fugl-Meyer and COPM (Canadian Occupational Performance Measure) tools. The independent T-test, Chi-square, and ANOVA with repeated measures were used to analyze the data. The results showed that the interaction effect of time and group was not significant in none of the Fugl-Meyer test sections (p > 0. 05), but it was significant in the performance and satisfaction of COPM (p < 0.05). The results suggest that ICF-CS-based occupational therapy interventions may assist persons with chronic stroke improve their functional level and satisfaction.

Concurrent ankle-assisted movement, biofeedback, and proprioceptive stimulation reduces lower limb motor impairment and improves gait in persons with stroke. Physiother Theory Pract 2024; 40:477-486. [PMID: 36102364 DOI: 10.1080/09593985.2022.2122763] [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: 10/07/2021] [Revised: 07/20/2022] [Accepted: 09/05/2022] [Indexed: 10/14/2022]
Abstract
BACKGROUND Persons with stroke live with residual sensorimotor impairments in their lower limbs (LL), which affects their gait. PURPOSE We investigated whether these residual impairments and resulting gait deficits can be reduced through concurrently applied assisted movement, biofeedback, and proprioceptive stimulation. METHODS A robotic device provided impairment-oriented training to the affected LL of 24 persons with stroke (PwS) with moderate-to-severe LL impairment. Participants were given 22-30 training sessions over 2-3 months. During training, the interventional device cyclically dorsiflexed and plantarflexed the ankle at 5 deg/s through ±15 deg for 30 min while the participant assisted with the imposed movement. Concurrently, participants received visual biofeedback of assistive joint torque or agonist EMG while mechanical vibration was applied to the currently lengthening (i.e. antagonist) tendon. RESULTS Sensorimotor impairment significantly decreased over the training period, which was sustained over 3 months, based on the Fugl-Meyer Assessment (FMA-LL) (p < .001), modified Ashworth scale in dorsiflexors (p < .05), and an ankle strength test (dorsiflexors and plantarflexors) (p < .05). Balance and gait also improved, based on the Tinetti Performance Oriented Mobility Assessment (POMA) (p < .05). CONCLUSION Impairment-oriented training using a robotic device capable of applying assisted movement, biofeedback, and proprioceptive stimulation significantly reduces LL impairment and improves gait in moderately-to-severely impaired PwS.

Arch Phys Med Rehabil 2024:S0003-9993(24)00833-5.

Abstract
OBJECTIVE To determine clinically important differences (CIDs) on Section GG physical functioning scores on the Centers for Medicare and Medicaid Services (CMS) Inpatient Rehabilitation Facility Assessment Instrument (IRF-PAI) for patients with stroke, using anchor and distribution-based approaches. DESIGN Pilot prospective observational cohort study. SETTING Inpatient rehabilitation facility. PARTICIPANTS Patients with stroke (N=208). INTERVENTIONS Physicians assessed improvements during rehabilitation using the modified Rankin scale (mRS). Improvements (≥1 point) on the mRS were used as the anchor for establishing CIDs. MAIN OUTCOME MEASURES Classically summed and Rasch transformed Section GG change scores associated with clinically important improvements on the mRS. RESULTS A total of 166 patients (79.8%) improved ≥1 point on the mRS. Change scores of 27, 9, and 16 on Section GG total physical functioning (self-care + mobility), self-care, and mobility/walk scales, respectively, had high sensitivity (0.82-0.85) but low specificity (0.52-0.69) in identifying patients improving on the mRS. Positive predictive values ranged from 0.87 to 0.91, and negative predictive values ranged from 0.42 to 0.52. Total physical functioning and selfcare anchor-derived change scores were similar to the reliable change index (RCI [2.77 × SEM]), calculated as 28 and 10 points, respectively, whereas anchor-derived mobility/walk scale change scores were equivalent to 1.96 × SEM. Exploratory Rasch modeling identified 3 Section GG subscales (R-Self-Care, R-Mobility, and R-Walking). Improvements on the R-Walking subscale were most correlated with mRS improvements (ρ=-0.47); however, accuracy of CID estimates was not improved. CONCLUSIONS Cut-off scores obtained using the mRS anchor aligned with more robust estimates of change, as estimated by distribution-based measures. While patients achieving anchor-derived cut-offs have a high probability of mRS improvement, change scores may fail to detect clinically meaningful improvements at these same thresholds. Alternative criteria for determining MCID/CIDs, should be explored. Rasch models require further validation.

Abstract
BACKGROUND Persons after stroke present with an altered arm swing during walking. Given the known influence of the arm swing on gait, it is important to identify the characteristics of persons with stroke with different arm-to-leg coordination patterns during walking. METHODS Twenty-five persons after stroke walked on a self-paced treadmill at comfortable walking speed. The frequency of shoulder movements per stride was detected by Fast Fourier transform analysis on the kinematic data for hemiplegic shoulder movements in the sagittal plane. An independent-sample t-test or Mann-Whitney U test was used to compare clinical and biomechanical parameters between identified subgroups. RESULTS Two earlier described subgroups based on the number of shoulder flexion-extension movements during one stride could be confirmed. Participants in the 1:1 ratio subgroup (one arm swing during one stride, N = 15) presented with a less upper limb impairment and less spasticity of the elbow extensors (p = 0.012) than the participants in the 2:1 ratio subgroup (two arm swings during one stride, N = 9). Although not significant, the participants in the 1:1 subgroup also seemed to have less spasticity of the shoulder internal rotators (p = 0.06) and a less walking variability based on the standard deviation of the step width. Further research on a greater sample should confirm these findings. CONCLUSION Fast Fourier transform analysis was used to identify subgroups based on sagittal shoulder kinematics during walking. The clinical and gait related differences between the identified subgroups can be taken into account in future research investigating post-stroke gait interventions aiming to improve the arm swing.

Abstract
There is a growing awareness of the significance of using minimum clinically important differences (MCIDs) in stroke research. An MCID is the smallest change in an outcome measure that is considered clinically meaningful. This review is the first to provide a comprehensive summary of various scales and patient-reported outcome measures (PROMs) used in stroke research and their MCID values reported in the literature, including a concise overview of the concept of and methods for determining MCIDs in stroke research. Despite the controversies and limitations surrounding the estimation of MCIDs, their importance in modern clinical trials cannot be overstated. Anchor-based and distribution-based methods are recommended for estimating MCIDs, with patient self-evaluation being a crucial component in capturing the patient's perspective on their health. A combination of methods can provide a more comprehensive understanding of the clinical relevance of treatment effects, and incorporating the patient's perspective can enhance the care of stroke patients.

PM R 2023. [PMID: 37905358 DOI: 10.1002/pmrj.13092] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 10/07/2023] [Accepted: 10/16/2023] [Indexed: 11/02/2023]
Abstract
BACKGROUND Vertebral compression fractures, which are commonly associated with older age and osteoporotic fractures, have an increased risk of re-fracture. Therefore, improving balance is important to prevent falls. The minimal important change (MIC) has been recommended for interpreting clinically meaningful changes in rating scales. The MIC of the Berg Balance Scale (BBS) for use in older women with vertebral compression fractures has not been established. OBJECTIVE To identify the MIC of the BBS that can be used in older women with vertebral compression fractures using predictive modeling methods and the receiver-operating characteristic (ROC)-based method. DESIGN A retrospective longitudinal multicenter study. PATIENTS Sixty older women (mean age ± standard deviation: 84.1 ± 7.0 years) with vertebral compression fractures who were unable to ambulate independently on a level surface. METHODS A change of one point in the Functional Ambulation Category (FAC) was used as an anchor to calculate the MIC of the BBS based on the change between admission and discharge. We calculated the MIC for the women whose FAC score improved by ≥1 point. We used three anchor-based methods to examine the MIC: the ROC-based method (MICROC ), the predictive modeling method (MICpred ), and the MICpred -based method adjusted by the rate of improvement and reliability of transition (MICadj ). RESULTS Thirty-nine women comprised the "important change" group based on their FAC score improvement. In this group, the MICROC (95% confidence interval [CI]) value of the BBS was 10.0 points (5.5-15.5), with an area under the curve of 0.71. The MICpred (95% CI) value was 9.7 (8.1-11.0), and the MICadj (95% CI) was 7.0 (5.5-8.5) points. CONCLUSION For women with vertebral compression fractures who are unable to ambulate independently, a 7.0-point improvement in the BBS score may be a useful indicator for reducing the amount of assistance required for walking.

Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) and foot drop stimulators (FDS) are widely used for stroke rehabilitation. However, no study has investigated if tDCS could boost the effects of FDS and gait training in improving clinical parameters and neuroplasticity biomarkers of chronic post-stroke subjects. OBJECTIVE To investigate the effects of combining tDCS and FDS on motor impairment, functional mobility, and brain-derived neurotrophic factor (BDNF) serum levels. Also, to evaluate the effects of this protocol on the insulin-like growth factor-1 (IGF-1), insulin growth factor-binding proteins-3 (IGFBP-3), interleukin (IL) 6 and 10, and tumor necrosis factor-α (TNF-α) levels. METHODS Thirty-two chronic post-stroke individuals were randomized to tDCS plus FDS or sham tDCS plus FDS groups. Both groups underwent ten gait training sessions for two weeks using a FDS device and real or sham tDCS. Blood samples and clinical data were acquired before and after the intervention. Motor impairment was assessed by the Fugl-Meyer Assessment and functional mobility using the Timed up and Go test. RESULTS Both groups improved the motor impairment and functional mobility and increased the BDNF levels. Both groups also increased the IL-10 and decreased the cortisol, IL-6, and TNF-α levels. No difference was observed between groups. CONCLUSION tDCS did not add effect to FDS and gait training in improving clinical parameters and neuroplasticity biomarkers in chronic post-stroke individuals. Only FDS and gait training might be enough for people with chronic stroke to modify some clinical parameters and neuroplasticity biomarkers.

Abstract
Objective Motor recovery is crucial in stroke rehabilitation, and acupuncture can influence recovery. Neuroimaging and machine learning approaches provide new research directions to explore the brain functional reorganization and acupuncture mechanisms after stroke. We applied machine learning to predict the classification of the minimal clinically important differences (MCID) for motor improvement and identify the neuroimaging features, in order to explore brain functional reorganization and acupuncture mechanisms for motor recovery after stroke. Methods In this study, 49 patients with unilateral motor pathway injury (basal ganglia and/or corona radiata) after ischemic stroke were included and evaluated the motor function by Fugl-Meyer Assessment scores (FMA) at baseline and at 2-week follow-up sessions. Patients were divided by the difference between the twice FMA scores into one group showing minimal clinically important difference (MCID group, n = 28) and the other group with no minimal clinically important difference (N-MCID, n = 21). Machine learning was performed by PRoNTo software to predict the classification of the patients and identify the feature brain regions of interest (ROIs). In addition, a matched group of healthy controls (HC, n = 26) was enrolled. Patients and HC underwent magnetic resonance imaging examination in the resting state and in the acupuncture state (acupuncture at the Yanglingquan point on one side) to compare the differences in brain functional connectivity (FC) and acupuncture effects. Results Through machine learning, we obtained a balance accuracy rate of 75.51% and eight feature ROIs. Compared to HC, we found that the stroke patients with lower FC between these feature ROIs with other brain regions, while patients in the MCID group exhibited a wider range of lower FC. When acupuncture was applied to Yanglingquan (GB 34), the abnormal FC of patients was decreased, with different targets of effects in different groups. Conclusion Feature ROIs identified by machine learning can predict the classification of stroke patients with different motor improvements, and the FC between these ROIs with other brain regions is decreased. Acupuncture can modulate the bilateral cerebral hemispheres to restore abnormal FC via different targets, thereby promoting motor recovery after stroke.

Abstract
INTRODUCTION The Motricity Index (MI) can predict motor function after rehabilitation, but its minimal clinically important difference (MCID) has not been established. The primary study aim was to estimate the MCID value of the MI arm score. METHODS Between 2017 and 2018, 173 participants hospitalized with confirmed ischemic stroke were recruited into an observational rehabilitation study. Participants with motor weakness as measured by the Fugl-Meyer upper-extremity (FM-UE) and MI with complete baseline and follow-up assessments at 3 months were included in this analysis. The longitudinal recovery of the MI arm score was anchored to having a poor outcome based on the FM-UE recovery (<9) longitudinally. Results reported include the area-under-curve (AUC), along with sensitivity, specificity, and optimal cut-points based on maximizing the Youden statistic. RESULTS Sixty-nine patients (median [IQR] age 70 [18] years; 48% male; 54% white) were included in the final analysis. Mean ± standard deviation outcome scores at 3-months were: MI arm: 83.19 ± 22.80; FM-UE: 53.04 ± 17.26. For the primary results, the MI arm score optimal MCID cutoff for observed recovery was 13 points with a sensitivity of 80% (95% Confidence Interval (CI)(67.6%, 92.4%)) and a specificity of 69.0% (95% CI (52.1, 85.8%)), and the AUC was 0.8082 (0.7007, 0.9157). CONCLUSIONS This was the first study to report the MCID of the MI arm score, as anchored to the FM-UE recovery between acute evaluation and 3-months. The estimated optimal MCID of improvement in the MI arm score was 13 points.

Abstract
OBJECTIVES To explore the synergic effect of the combination of mirror therapy and electrical stimulation on lower limb motor function recovery in stroke survivors. MATERIALS AND METHODS PubMed, Web of Science, Embase, Cochrane Library, CINAHL, CNKI, Wan Fang, CBM were searched from inception to December 2020. Randomized controlled trials that compared the combined therapy with another single therapy were included. A pre-determined data collection form was used to extract data. Two authors independently extracted data and used the Cochrane Handbook criteria to assess the quality of included studies. RESULTS Six studies, with a total of 437 patients were included. There was an overall positive effect on lower limb motor function recovery, according to Fugl-Meyer Assessment for the Lower Extremity [all: WMD in fixed effects model: 5.63, 95% CI 4.86, 6.39] and Brunnstrom stage [all: WMD in fixed effects model: 0.49, 95% CI 0.32, 0.66]. CONCLUSIONS The results indicate that the combination of mirror therapy and electrical stimulation for lower extremity motor function recovery in stroke survivors may have a positive effect.

Syst Rev 2022; 11:260. [PMID: 36463306 PMCID: PMC9719113 DOI: 10.1186/s13643-022-02100-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/25/2021] [Accepted: 10/14/2022] [Indexed: 12/04/2022] Open
Abstract
BACKGROUND This overview summarizes the best available systematic review (SR) evidence on the health effects of Tai Chi. METHODS Nine databases (PubMed, Cochrane Library, EMBASE, Medline, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP), Sino-Med, and Wanfang Database) were searched for SRs of controlled clinical trials of Tai Chi interventions published between Jan 2010 and Dec 2020 in any language. Effect estimates were extracted from the most recent, comprehensive, highest-quality SR for each population, condition, and outcome. SR quality was appraised with AMSTAR 2 and overall certainty of effect estimates with the GRADE method. RESULTS Of the 210 included SRs, 193 only included randomized controlled trials, one only included non-randomized studies of interventions, and 16 included both. Common conditions were neurological (18.6%), falls/balance (14.7%), cardiovascular (14.7%), musculoskeletal (11.0%), cancer (7.1%), and diabetes mellitus (6.7%). Except for stroke, no evidence for disease prevention was found; however, multiple proxy-outcomes/risks factors were evaluated. One hundred and fourteen effect estimates were extracted from 37 SRs (2 high, 6 moderate, 18 low, and 11 critically low quality), representing 59,306 adults. Compared to active and/or inactive controls, 66 of the 114 effect estimates reported clinically important benefits from Tai Chi, 53 reported an equivalent or marginal benefit, and 6 an equivalent risk of adverse events. Eight of the 114 effect estimates (7.0%) were rated as high, 43 (37.7%) moderate, 36 (31.6%) low, and 27 (23.7%) very low certainty evidence due to concerns with risk of bias (92/114, 80.7%), imprecision (43/114, 37.7%), inconsistency (37/114, 32.5%), and publication bias (3/114, 2.6%). SR quality was often limited by the search strategies, language bias, inadequate consideration of clinical, methodological, and statistical heterogeneity, poor reporting standards, and/or no registered SR protocol. CONCLUSIONS The findings suggest Tai Chi has multidimensional effects, including physical, psychological and quality of life benefits for a wide range of conditions, as well as multimorbidity. Clinically important benefits were most consistently reported for Parkinson's disease, falls risk, knee osteoarthritis, low back pain, cerebrovascular, and cardiovascular diseases including hypertension. For most conditions, higher-quality SRs with rigorous primary studies are required. SYSTEMATIC REVIEW REGISTRATION PROSPERO CRD42021225708.

Abstract
OBJECTIVE This study aims to systematically evaluate the effects of Baduanjin on motor function, balance and gait in patients with Parkinson's disease (PD). DESIGN Systematic review and meta-analysis. STUDY SELECTION All eligible randomised controlled trials (RCTs) published in the English and Chinese language were included. DATA SOURCES Ten electronic databases were systematically searched, from inception to 17 March 2022: PubMed, Web of Science, Cochrane Library, Embase, EBSCOhost, OVID, SinoMed, China National Knowledge Infrastructure, Wanfang Data and China Science Journal Database (VIP). REVIEW METHODS Methodological quality assessment and meta-analysis were performed for the included studies using the Cochrane Review Manager V.5.4 software. RESULTS Ten RCTs with 804 participants were included. The results revealed the following: (1) Baduanjin significantly improved the motor function of patients with PD, based on the Unified Parkinson's Disease Rating Scale Part III (mean difference, MD -5.37, 95% CI -8.96 to -1.78, p=0.003) and Fugl-Meyer Assessment of Lower Extremity (MD 5.39, 95% CI 2.71 to 8.07, p<0.0001); (2) Baduanjin significantly improved the ability of balance of patients with PD, based on the Berg Balance Scale (MD 4.40, 95% CI 3.08 to 5.73, p<0.00001); (3) Baduanjin significantly improved the gait of patients with PD, based on the 6 min walk distance (MD 21.62, 95% CI 11.14 to 32.10, p<0.0001). After the further subgroup and sensitivity analyses, the heterogeneity was identified to be potentially due to the different degrees of disease severity in patients with PD and the difference in Baduanjin intervention durations. CONCLUSIONS The analysis of this systematic evaluation indicates that Baduanjin might have a positive effect in improving the motor function, balance and gait of patients with PD. However, due to the quantity and clinical heterogeneity limitations of the included studies, this conclusion still warrants more high-quality and multicentre RCTs for further verification.

Abstract
Background Robot-assisted gait training (RAGT) is a practical treatment that can complement conventional rehabilitation by providing high-intensity repetitive training for patients with stroke. RAGT systems are usually either of the end-effector or exoskeleton types. We developed a novel hybrid RAGT system that leverages the advantages of both types. Objective This single-blind randomized controlled trial evaluated the beneficial effects of the novel RAGT system both immediately after the intervention and at the 3-month follow-up in nonambulatory patients with subacute stroke. Methods We recruited 40 patients with subacute stroke who were equally randomized to receive conventional rehabilitation either alone or with the addition of 15 RAGT sessions. We assessed lower-extremity motor function, balance, and gait performance by using the following tools: active range of motion (AROM), manual muscle test (MMT), the Fugl–Meyer Assessment (FMA) lower-extremity subscale (FMA-LE) and total (FMA-total), Postural Assessment Scale for Stroke (PASS), Berg Balance Scale (BBS), Tinetti Performance-Oriented Mobility Assessment (POMA) balance and gait subscores, and the 3-m and 6-m walking speed and Timed Up and Go (TUG) tests. These measurements were performed before and after the intervention and at the 3-month follow-up. Results Both groups demonstrated significant within-group changes in the AROM, MMT, FMA-LE, FMA-total, PASS, BBS, POMA, TUG, and 3-m and 6-m walking speed tests before and after intervention and at the 3-month follow-up (p < 0.05). The RAGT group significantly outperformed the control group only in the FMA-LE (p = 0.014) and total (p = 0.002) assessments. Conclusion Although the novel hybrid RAGT is effective, strong evidence supporting its clinical effectiveness relative to controls in those with substantial leg dysfunction after stroke remains elusive.

Is virtual reality training superior to conventional treatment in improving lower extremity motor function in chronic hemiplegic patients? Turk J Phys Med Rehabil 2022; 68:391-398. [DOI: 10.5606/tftrd.2022.9081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 11/29/2021] [Indexed: 11/27/2022] Open
Abstract
Objectives: This study aims to examine the effect of virtual reality (VR) training, frequently included in rehabilitation programs, on lower extremity functional status, mobility, balance, and walking speed in chronic stroke patients.
Patients and methods: This randomized, controlled study was conducted with 60 chronic stroke patients (26 males, 34 females; mean age: 64.0 years; range, 33 to 80 years) who presented to the physical therapy and rehabilitation outpatient clinic of the Kütahya Health Sciences University Evliya Çelebi Training and Research Hospital between February 2019 and February 2020. The participants were randomized to the VR group and the control group by simple randomization with 1:1 allocation. The VR group received 30 min of VR training and 30 min of conventional physiotherapy, while the control group received 60 min of conventional physiotherapy. The patients were evaluated before and after treatment using the Fugl-Meyer Assessment-Lower Extremity (FMA-LE), Rivermead Mobility Index (RMI), 10-m walk test (10MWT), and Berg Balance Scale (BBS).
Results: The FMA-LE, RMI, 10MWT, and BBS scores significantly improved in both groups after treatment (p<0.001). The post-treatment change in the FMA-LE score was significantly higher in the VR group than in the control group (Z=-3.560, p<0.001). Similarly, the change in the BBS score was significantly higher in the VR group (Z=-3.769, p<0.001). Post-treatment changes in the RMI and 10MWT were not significant (p>0.05).
Conclusion: Virtual reality training combined with conventional physiotherapy was found to be superior to conventional physiotherapy alone in improving lower extremity functional status in chronic stroke patients; therefore, adding a VR component to rehabilitation programs will have a favorable impact on treatment outcomes.

Abstract
BACKGROUND: Stroke often leads to lower extremity impairments that significantly hinders functional recovery. OBJECTIVE: To investigate the effectiveness of constraint-induced movement therapy for the lower extremity (CIMT-LE) for improving balance and ambulation among people post-stroke. METHODS: A randomized controlled, single-blinded clinical trial was conducted. Participants were recruited and randomized into one of two groups: CIMT-LE group and control. Outcome measures were the Fugl-Meyer assessment of lower extremity, Berg balance scale, ten-meter walk test and six-minute walk test. Outcome measures were collected at baseline, following the conclusion of the therapeutic programs and after three months. RESULTS: 38 participants were enrolled in the study (19 in each group). No significant differences were found between groups at baseline. At the conclusion of therapeutic programs, both groups showed significant changes compared to baseline. However, changes seen in the CIMT-LE were clinically significant. Further, at three months following the conclusion of the program, the recorded improvements were retained by participants. CONCLUSION: A CIMT-LE program compared to an intensity-matched conventional program yielded significant clinical improvements among people post-stroke. These improvements were seen in lower extremity motor recovery, postural balance and gait speed. Furthermore, these improvements were retained three months following the conclusion of the therapeutic program.

Abstract
The central nervous system (CNS) control of human gait is complex, including descending cortical control, affective ascending neural pathways, interhemispheric communication, whole brain networks of functional connectivity, and neural interactions between the brain and spinal cord. Many important studies were conducted in the past, which administered gait training using externally targeted methods such as treadmill, weight support, over-ground gait coordination training, functional electrical stimulation, bracing, and walking aids. Though the phenomenon of CNS activity-dependent plasticity has served as a basis for more recently developed gait training methods, neurorehabilitation gait training has yet to be precisely focused and quantified according to the CNS source of gait control. Therefore, we offer the following hypotheses to the field: Hypothesis 1. Gait neurorehabilitation after stroke will move forward in important ways if research studies include brain structural and functional characteristics as measures of response to treatment. Hypothesis 2. Individuals with persistent gait dyscoordination after stroke will achieve greater recovery in response to interventions that incorporate the current and emerging knowledge of CNS function by directly engaging CNS plasticity and pairing it with peripherally directed, plasticity-based motor learning interventions. These hypotheses are justified by the increase in the study of neural control of motor function, with emerging research beginning to elucidate neural factors that drive recovery. Some are developing new measures of brain function. A number of groups have developed and are sharing sophisticated, curated databases containing brain images and brain signal data, as well as other types of measures and signal processing methods for data analysis. It will be to the great advantage of stroke survivors if the results of the current state-of-the-art and emerging neural function research can be applied to the development of new gait training interventions.

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.

Abstract
Background:
Mesenchymal stem cells (MSCs) secrete trophic factors and extracellular vesicles (EVs). However, the level and role of EVs after MSC therapy in patients with stroke are unknown. We investigated whether circulating EVs and trophic factors are increased after MSCs and are related to the therapeutic benefits in the STARTING-2 trial (Stem Cell Application Researches and Trials in Neurology-2) participants.
Methods:
In this prospective randomized controlled trial, patients with chronic major stroke were assigned, in a 2:1 ratio, to receive autologous MSC intravenous injection (MSC group, n=39) or standard treatment (control group, n=15) and followed for 3 months. Detailed clinical assessment and neuroplasticity on diffusion tensor image and resting-state functional magnetic resonance imaging were evaluated. Serial samples were collected, before/after MSCs therapy. The primary outcome measure was circulating factors that are associated with the clinical improvement in the Fugl-Meyer Assessment (secondary end point of the trial) and neuroplasticity on diffusion tensor image and resting-state functional magnetic resonance imaging. Additional outcome measures were microRNAs and trophic factors enriched in the plasma EVs, obtained using quantitative polymerase chain reaction and ELISA, respectively.
Results:
Circulating EV levels were increased ≈5-fold (mean±SD, from 2.7×10
9
±2.2×10
9
to 1.3×10
10
±1.7×10

EVs/mL) within 24 hours after injection of MSCs (
P
=0.001). After adjustment of age, sex, baseline stroke severity, and the time interval from stroke onset to treatment, only the EV number was independently associated with improvement in motor function (odds ratio, 5.718 for EV number
Log
[95% CI, 1.144–28.589];
P
=0.034). Diffusion tensor image and resting-state functional magnetic resonance imaging showed that integrity of the ipsilesional corticospinal tract and intrahemispheric motor network were significantly correlated with circulating EV levels, respectively (
P
<0.05). MicroRNAs related to neurogenesis/neuroplasticity (eg, microRNA-18a-5p) were significantly increased in circulating EVs after MSC therapy (
P
=0.0479). In contrast, trophic factor levels were not changed after MSC therapy.
Conclusions:
This trial is the first to show that treatment of ischemic stroke patients with MSCs significantly increases circulating EVs, which were significantly correlated with improvement in motor function and magnetic resonance imaging indices of plasticity.

Abstract
BACKGROUND Fatigue assessment scale (FAS), fatigue subscale of the Profile of Mood States (POMS-F), and vitality subscale of the Short Form Health Survey (SF-36-VT) are among the first and most widely used adapted tools for assessing post-stroke fatigue. OBJECTIVE To identify the minimal clinically important difference (MCID) and robust clinically important difference (RCID) of FAS, POMS-F, and SF-36-VT in stroke survivors. METHODS Participants completed the FAS, POMS-F, and SF-36-VT before and after receiving 6-week intervention including graded activity training and pacing therapy. MCID was calculated using the distribution-based and anchor-based methods. Further, accuracy, sensitivity, and specificity of calculated values using the distribution-based method were used for determining RCID. RESULT A total of 124 stroke survivors participated in this study. MCID for FAS, POMS-F, and SF-36-VT was found to be 4.86, 3.32, and -10.10 (using score change) and 3.5, 2.5, and -10.5 (using ROC analysis), respectively. Using the distribution-based method, the MCID value obtained for the FAS was in the range of 3.16 to 8.76, for the POMS-F was in the range of 1.49 to 5.63, and for the SF-36-VT was in the range of -15.43 to -5.58. ½SD for FAS, ½ SD and 1.96 SEM for POMS-F, and 1.96 SEM and SD for SF-36-VT showed the best discriminative ability to use as the RCID. CONCLUSIONS The MCID and RCID were calculated for FAS, POMS-F, and SF-36-VT using different methods. The results can be used by researchers and clinicians for interpreting their findings in subjects similar to those who participated in this study.

Influence of Transcranial Direct Current Stimulation Dosage and Associated Therapy on Motor Recovery Post-stroke: A Systematic Review and Meta-Analysis. Front Aging Neurosci 2022; 14:821915. [PMID: 35370603 PMCID: PMC8972130 DOI: 10.3389/fnagi.2022.821915] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Accepted: 02/14/2022] [Indexed: 11/21/2022] Open
Abstract
Purpose (1) To determine the impact of transcranial direct current stimulation (tDCS) applied alone or combined with other therapies on the recovery of motor function after stroke and (2) To determine tDCS dosage effect. Methods Randomized controlled trials comparing the effects of tDCS with sham, using the Barthel Index (BI), the upper and lower extremity Fugl–Meyer Assessment (FMA), and the Modified Ashworth Scale (MAS), were retrieved from PubMed, Medline (EBSCO), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from their inception to June 2021. Calculations for each assessment were done for the overall effect and associated therapy accounting for the influence of stroke severity or stimulation parameters. Results A total of 31 studies involving metrics of the BI, the upper extremity FMA, the lower extremity FMA, and the MAS were included. tDCS combined with other therapies was beneficial when assessed by the BI (mean difference: 6.8; P < 0.01) and these studies typically had participants in the acute stage. tDCS effects on the upper and lower extremity FMA are unclear and differences between the sham and tDCS groups as well as differences in the associated therapy type combined with tDCS potentially influenced the FMA results. tDCS was not effective compared to sham for the MAS. Stimulation types (e.g., anodal vs. cathodal) did not influence these results and dosage parameters were not associated with the obtained effect sizes. Conventional therapy associated with tDCS typically produced greater effect size than assisted therapy. The influence of stroke severity is unclear. Conclusion Potential benefits of tDCS can vary depending on assessment tool used, duration of stroke, and associated therapy. Mechanistic studies are needed to understand the potential role of stimulation type and dosage effect after stroke. Future studies should carefully conduct group randomization, control for duration of stroke, and report different motor recovery assessments types.

J Clin Neurol 2022; 18:308-314. [PMID: 35196746 PMCID: PMC9163946 DOI: 10.3988/jcn.2022.18.3.308] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 09/08/2021] [Accepted: 09/08/2021] [Indexed: 12/04/2022] Open
Abstract
Background and Purpose The objective of this study was to identify 2-year longitudinal changes in the muscle thickness (MT) and echo intensity (EI) of the abdominal, thigh, and lower limb muscles in chronic stroke survivors. Methods This study included 15 chronic stroke survivors aged 74.1±9.9 years. The MT, EI, and subcutaneous fat thickness values of the following muscles on the paretic and nonparetic sides were assessed on transverse ultrasound images: rectus abdominis, external oblique, internal oblique, transversus abdominis, rectus femoris (RF), vastus intermedius, vastus lateralis (VL), vastus medialis, tibialis anterior, gastrocnemius, and soleus. The ultrasound measurements were performed both at baseline and 2 years later. Results After 2 years, the VL on the paretic side showed a significant decrease in MT (p=0.031) and increase in EI (p=0.002), whereas the RF on the nonparetic side showed a significant decrease in EI (p=0.046). Correlation coefficient analyses showed that changes in MT (r=0.668, p=0.012) and EI (r=0.597, p=0.018) of the VL on the paretic side were significantly associated with a change in the body mass index. Conclusions The findings of this longitudinal study suggest that the VL on the paretic side is subject to deteriorations in muscle quantity and quality, and conversely that the RF on the nonparetic side shows an improvement in muscle quality after 2 years in chronic stroke survivors.

J Pers Med 2021; 11:jpm11111137. [PMID: 34834489 PMCID: PMC8621313 DOI: 10.3390/jpm11111137] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2021] [Revised: 10/25/2021] [Accepted: 10/29/2021] [Indexed: 01/01/2023] Open
Abstract
The aim of this study was to identify factors associated with improved motor function of the lower extremities in response to mesenchymal stem cell (MSC) therapy in patients with ischemic stroke. This study was a post hoc analysis of data from a prospective, open-label, randomized controlled trial of MSC therapy for patients with ischemic stroke patients associated with severe middle cerebral artery territory (STARTING-2 trial). Lower limb motor function was scored based on the lower limb of Fugl-Meyer assessment (FMA-LL) score before MSC therapy and at 3 months after stroke. All FMA-LL changes greater than or equal to six points were considered clinically significant. Univariate and multivariate binary logistic regression models were used to determine possible predictors of clinically significant lower limb motor response to MSC therapy. Twelve (33%) of the thirty-six patients receiving MSC therapy reached a minimal clinically important difference (MCID) of FMA-LL. The two independent factors with the greatest impact on response to MSC therapy for achieving an MCID in FMA-LL score were: (1) the time from stroke onset to MSC therapy, and (2) age (p < 0.05). In addition, obese stroke patients responded better to MSC therapy than stroke patients with normal weight. In conclusion, this post hoc analysis might suggest the need for recruiting stroke patients at younger and early after stroke onset in future clinical trials of MSC therapy for stroke.

Abstract
OBJECTIVE To determine minimally clinically important differences (MCIDs) for Disability Rating Scale (DRS), Fugl-Meyer Upper Extremity Subscale (FM-UE), Fugl-Meyer Lower Extremity Subscale (FM-LE), and Fugl-Meyer Motor Scale (FMMS) in patients with chronic motor deficits secondary to traumatic brain injury (TBI). METHODS Retrospective analysis from the 1-year, double-blind, randomized, surgical sham-controlled, Phase 2 STEMTRA trial (NCT02416492), in which patients with chronic motor deficits secondary to TBI (N = 61) underwent intracerebral stereotactic implantation of modified bone marrow-derived mesenchymal stromal (SB623) cells. MCIDs for DRS, FM-UE, FM-LE, and FMMS were triangulated with distribution-based, anchor-based, and Delphi panel estimates. RESULTS Triangulated MCIDs were: 1) -1.5 points for the Disability Rating Scale; 2) 6.2 points for the Fugl-Meyer Upper Extremity Subscale; 3) 3.2 points for the Fugl-Meyer Lower Extremity Subscale; and 4) 8.4 points for the Fugl-Meyer Motor Scale. CONCLUSIONS For the first time in the setting of patients with chronic motor deficits secondary to TBI, this study reports triangulated MCIDs for: 1) DRS, a measure of global outcome; and 2) Fugl-Meyer Scales, measures of motor impairment. These findings guide the use of DRS and Fugl-Meyer Scales in the assessment of global disability outcome and motor impairment in future TBI clinical trials.

Abstract
PURPOSE The minimal clinically important difference (MCID) is the smallest clinically significant difference in treatment identified as crucial to the patient. There is no known MCID for the Berg Balance Scale (BBS), which measures balance function in patients with hip fractures. We aimed to calculate the MCID of the BBS in older adults with hip fractures. MATERIALS AND METHODS This is a retrospective multicenter clinical study that included 187 older adults with hip fractures. MCID was calculated using functional ambulation categories (FACs), which were used as anchors for the change in BBS scores between admission and discharge. MCID was calculated as an improvement for more than one point and as a substantial change for improvement for more than two points in the FAC. RESULTS MCID of the BBS was 11.5 points and that of the substantial change was 18.5 points, with an area under the curve of 0.76 and 0.81, respectively. CONCLUSIONS MCID for the BBS was 11.5 points in older adults with hip fractures. In addition, an improvement of more than 18.5 points in BBS can be considered a substantial change. These values may be useful in determining meaningful balance function improvement.Implications for rehabilitationHip fractures are a common injury for the older adults, and improvement in gait function has a bearing on prognosis.The effectiveness of meaningful rehabilitation is possible to determine by clarifying the minimal clinically important difference in balance function, which is important for the acquisition of gait.An improvement of 11.5 points or more on the Berg Balance Scale in an older adult with a hip fracture is considered a meaningful effect.

Abstract
Chiropractic spinal adjustments have been shown to result in short-term increases in muscle strength in chronic stroke patients, however, the effect of longer-term chiropractic spinal adjustments on people with chronic stroke is unknown. This exploratory study assessed whether 4 weeks of chiropractic spinal adjustments, combined with physical therapy (chiro + PT), had a greater impact than sham chiropractic with physical therapy (sham + PT) did on motor function (Fugl Meyer Assessment, FMA) in 63 subacute or chronic stroke patients. Secondary outcomes included health-related quality of life and other measures of functional mobility and disability. Outcomes were assessed at baseline, 4 weeks (post-intervention), and 8 weeks (follow-up). Data were analyzed using linear mixed-effects models or generalized linear mixed models. A post-hoc responder analysis was performed to investigate the clinical significance of findings. At 4 weeks, there was a larger effect of chiro + PT, compared with sham + PT, on the FMA (difference = 6.1, p = 0.04). The responder analysis suggested the improvements in motor function seen following chiropractic spinal adjustments may have been clinically significant. There was also a robust improvement in both groups in most measures from baseline to the 4- and 8-week assessments, but between-group differences were no longer significant at the 8-week assessment. Four weeks of chiro + PT resulted in statistically significant improvements in motor function, compared with sham + PT, in people with subacute or chronic stroke. These improvements appear to be clinically important. Further trials, involving larger group sizes and longer follow-up and intervention periods, are required to corroborate these findings and further investigate the impacts of chiropractic spinal adjustments on motor function in post-stroke survivors.

Abstract
BACKGROUND An individual's level of lower limb motor function is associated with his or her disability level after stroke, and motor improvement may lead to a better prognosis and quality of life. Data from animal models show that Qizhitongluo (QZTL) capsule facilitates recovery after focal brain injury. We aimed to validate the efficacy and safety of the QZTL capsule for promoting lower limb motor recovery in poststroke patients. METHODS In this randomized, multicenter, double-blind, placebo- and active-controlled trial from 13 sites in China, participants with ischemic stroke and Fugl-Meyer motor scale (FMMS) scores of <95 were eligible for inclusion. Patients were randomly assigned in a 2:1:1 ratio to the QZTL group, Naoxintong (NXT) group or placebo group for 12 weeks at 15-28 days after the onset of stroke. The primary outcome was the change in the Lower Limb FMMS (FMMS-LL) score from baseline over the 12-week intervention period. RESULTS 622 participants were randomly assigned to the QZTL group (309), NXT group (159), or placebo group (154). The FMMS-LL score increased by 4.81 points (95 % CI, 4.27-5.35) in the QZTL group, by 3.77 points (95 % CI, 3.03-4.51) in the NXT group and by 3.00 points (95 % CI, 3.03-4.51) in the placebo group at week 12. The QZTL group showed significantly larger improvements compared with the placebo group at each interview from weeks 4-12 (difference, 0.89 [0.30,1.49] at week 4, P = 0.0032; difference, 1.83[1.01,2.66] at 90 days poststroke, P < 0.0001; difference, 1.81[0.88,2.74] at week 12, P = 0.0001). CONCLUSION The QZTL capsule is an effective treatment for lower limb motor impairment. The finding indicates that the QZTL capsule may be used as a potential new strategy for stroke rehabilitation.

Abstract
OBJECTIVE To test whether autologous modified mesenchymal stem cells (MSCs) improve recovery in patients with chronic major stroke. METHODS In this prospective, open-label, randomized controlled trial with blinded outcome evaluation, patients with severe middle cerebral artery territory infarct within 90 days of symptom onset were assigned, in a 2:1 ratio, to receive preconditioned autologous MSC injections (MSC group) or standard treatment alone (control group). The primary outcome was the score on the modified Rankin Scale (mRS) at 3 months. The secondary outcome was to further demonstrate motor recovery. RESULTS A total of 39 and 15 patients were included in the MSC and control groups, respectively, for the final intention-to-treat analysis. Mean age of patients was 68 (range 28-83) years, and mean interval between stroke onset to randomization was 20.2 (range 5-89) days. Baseline characteristics were not different between groups. There was no significant difference between the groups in the mRS score shift at 3 months (p = 0.732). However, secondary analyses showed significant improvements in lower extremity motor function in the MSC group compared to the control group (change in the leg score of the Motricity Index, p = 0.023), which was notable among patients with low predicted recovery potential. There were no serious treatment-related adverse events. CONCLUSIONS IV application of preconditioned, autologous MSCs with autologous serum was feasible and safe in patients with chronic major stroke. MSC treatment was not associated with improvements in the 3-month mRS score, but we did observe leg motor improvement in detailed functional analyses. CLASSIFICATION OF EVIDENCE This study provides Class III evidence that autologous MSCs do not improve 90-day outcomes in patients with chronic stroke. CLINICALTRIALSGOV IDENTIFIER NCT01716481.

Abstract
BACKGROUND This study aimed to establish the minimal clinically important difference (MCID) for the Fugl-Meyer Motor Scale (FMMS) and the Disability Rating Scale (DRS) to evaluate interventions in patients with motor deficits in the chronic phase after traumatic brain injury (TBI). METHODS MCIDs were established with a structured expert consultation process, the RAND/UCLA modified Delphi method. This process consisted of a literature review and input from a 10-person, multidisciplinary expert panel. The experts were asked to rate meaningfulness of improvements in hypothetical patients and numeric changes via two rounds of ratings and an in-person meeting. RESULTS The estimated MCIDs were six and five points on the FMMS Upper and Lower Extremity Scale, respectively, and one point on the DRS. The experts argued against establishing an MCID for the combined FMMS because the same change was more likely to be meaningful if concentrated in one extremity and because a meaningful improvement in one extremity implies meaningfulness irrespective of the changes in the other. CONCLUSIONS This study is the first to establish MCIDs for the FMMS and the DRS in the chronic phase after TBI. The results may be helpful for the design and interpretation of clinical trials of interventions.

Lim JY, Oh MK, Park J, Paik NJ. Does Measurement of Corticospinal Tract Involvement Add Value to Clinical Behavioral Biomarkers in Predicting Motor Recovery after Stroke? Neural Plast 2020; 2020:8883839. [PMID: 33354207 PMCID: PMC7735861 DOI: 10.1155/2020/8883839] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2020] [Revised: 11/07/2020] [Accepted: 11/20/2020] [Indexed: 01/03/2023] Open
Abstract
Background The prediction of motor recovery after stroke is an important issue, and various prediction models have been proposed using either clinical behavioral or neurological biomarkers. This study sought to identify the effects of clinical behavioral biomarkers combined with corticospinal tract (CST) injury measurement on the prediction of motor recovery after stroke. Methods The region of interest was drawn on the normalized brain magnetic resonance imaging scans of patients with first-ever unilateral hemispheric stroke, and the degree of CST injury was calculated in a total of 67 such subjects. Patients who had initial minor deficits and showed a ceiling effect on motor recovery were excluded. To predict the follow-up Fugl-Meyer assessment (FMA) scores, correlation and regression analyses were performed using various clinical behavioral biomarkers, including age, sex, lesion location, and initial FMA scores and CST injury measurements. Results Only the initial FMA-upper extremity (UE) score was statistically correlated with the follow-up FMA-UE score at ≥2 months after the onset (adjusted R 2 = 0.626), and the relationship between CST injury and follow-up FMA-UE score was unclear (n = 53). Hierarchical clustering between the initial and follow-up FMA-UE scores showed three clusters. After exclusion of a cluster with an initial FMA-UE ≥ 35, the prediction of the follow-up FMA-UE score was possible by incorporating the initial FMA-UE score and CST injury measurements (n = 39). However, the explanatory power decreased (adjusted R 2 = 0.445), and the unique contribution of the CST injury (10.1%) was lower than that of the initial FMA-UE score (26.7%). With respect to the FMA-lower extremity score, CST injury was not related to recovery. Conclusions Motor recovery of the upper and lower extremities after stroke could be predicted using the initial FMA score. CST injury was significant for the prediction of motor recovery of the upper extremity in patients with severe initial motor deficits (FMA-UE < 35); however, its portion of prediction of motor recovery was low. The prediction of poststroke motor recovery using the initial motor deficit was not improved by the addition of CST injury measurements.

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
Hemiparesis resulting from a stroke has a direct impact on patients' daily activities. New approaches for motor rehabilitation include Serious Games (SG) because they include (in a motivating way) the three fundamental elements for rehabilitation: intensive, repetitive and task-oriented training. This study aims to evaluate the therapeutic effects of a biomedical SG and a scoring system developed for lower limb motor rehabilitation of hemiparetic stroke patients. The SG was inspired by the classic videogame called Pong, where the goal is to control a tennis racquet, but using muscular strength. A knee extensor apparatus was adapted with a load cell and mechanical adjustments for measuring the muscular strength of the quadriceps femoris (QFG) and hamstrings (HSG). A scoring system was proposed to evaluate muscular control. Eleven hemiparetic stroke patients participated in an exercise program using the SG twice a week for ten weeks and only the paretic side was trained. Significant Effect Sizes ( d ) were found for QFG strength ( d=0.5;p=0.021 ), QFG control ( ), HSG strength ( d=1.1; p = 0.001 ), HSG control ( d=1.5; p = 0.003 ), functional mobility ( ), gait speed ( d=0.4; p=0.007 ) and motor recovery ( ). Results indicate that the intervention of a SG with both proper apparatus and evaluation system may effectively promote lower limb motor rehabilitation of hemiparetic stroke patients.

Abstract
This study investigated the effectiveness of Ai Chi compared to conventional water-based exercise on balance performance in individuals with chronic stroke. A total of 20 individuals with chronic stroke were randomly allocated to receive either Ai Chi or conventional water-based exercise for 60 min/time, 3 times/week, and a total of 6 weeks. Balance performance assessed by limit of stability (LOS) test and Berg balance scale (BBS). Fugl-Meyer assessment (FMA) and gait performance were documented for lower extremity movement control and walking ability, respectively. Excursion and movement velocity in LOS test was significantly increased in anteroposterior axis after receiving Ai Chi (p = 0.005 for excursion, p = 0.013 for velocity) but not conventional water-based exercise. In particular, the improvement of endpoint excursion in the Ai Chi group has significant inter-group difference (p = 0.001). Both groups showed significant improvement in BBS and FMA yet the Ai Chi group demonstrated significantly better results than control group (p = 0.025). Ai Chi is feasible for balance training in stroke, and is able to improve weight shifting in anteroposterior axis, functional balance, and lower extremity control as compared to conventional water-based exercise.

Abstract
OBJECTIVE The aim of the study was to compare the effects of progressive reducing assistance force versus full assistance force controlled robot-assisted gait training combined with conventional physiotherapy on locomotor functions in patients with subacute stroke. DESIGN Inpatients with subacute stroke (N = 29; 16 men; Functional Ambulation Category score = 1 ± 0.9) were randomly assigned to one of two groups: a progressive reducing assistance force group (n = 15) or a full assistance force group (n = 14). The progressive reducing assistance force group performed robot-assisted gait training sessions from 100% assistance force at the outset to 60% assistance force at the end of the robot-assisted gait training, whereas the full assistance force group received 100% assistance force throughout the robot-assisted gait training sessions. Both groups performed robot-assisted gait training combined with conventional physiotherapy 5 days a week for 4 wks. After intervention, all patients then underwent only conventional physiotherapy 5 days a week for 4 wks of follow-up. RESULTS The Mann-Whitney U test between-group comparisons showed that improvements were significantly greater in the progressive reducing assistance force group for the Functional Ambulation Category, knee extensors torque, and Berg Balance Scale relative to the full assistance force group, both at postintervention and at follow-up. CONCLUSIONS Progressive reducing assistance force control during robot-assisted gait training combined with conventional physiotherapy may be more beneficial for improving locomotor functions in patients with subacute stroke.

Abstract
BACKGROUND Stroke often results in motor impairment and limited functional capacity. This study aimed to verify the relationship between widely used clinical scales and instrumented measurements to evaluate poststroke individuals with mild, moderate, and severe motor impairment. METHODS This cross-sectional study included 34 participants with chronic hemiparesis after stroke. Fugl-Meyer Assessment and Modified Ashworth Scale were used to quantify upper and lower limb motor impairment and the resistance to passive movement (i.e., spasticity), respectively. Upper limb Motor performance (movement time and velocities) and movement quality (range of motion, smoothness and trunk displacement) were analyzed during a reaching forward task using an optoelectronic system (instrumented measurement). Lower limb motor performance (gait and functional mobility parameters) was assessed by using an inertial measurement unit system. FINDINGS Fugl-Meyer Assessment correlated with motor performance (upper and lower limbs) and with movement quality (upper limb). Modified Ashworth scale correlated with movement quality (upper limb). Cutoff values of 9.0 cm in trunk anterior displacement and .57 m/s in gait velocity were estimated to differentiate participants with mild/moderate and severe compromise according to the Fugl-Meyer Assessment. CONCLUSIONS These results suggest that the Fugl-Meyer Assessment can be used to infer about motor performance and movement quality in chronic poststroke individuals with different levels of impairment.

J Neuroeng Rehabil 2019; 16:99. [PMID: 31358017 PMCID: PMC6664752 DOI: 10.1186/s12984-019-0553-5] [Citation(s) in RCA: 29] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2018] [Accepted: 06/19/2019] [Indexed: 11/10/2022] Open
Abstract
Background Balance impairments are common in patients with infratentorial stroke. Although robot-assisted gait training (RAGT) exerts positive effects on balance among patients with stroke, it remains unclear whether such training is superior to conventional physical therapy (CPT). Therefore, we aimed to investigate the effects of RAGT combined with CPT and compared them with the effects of CPT only on balance and lower extremity function among survivors of infratentorial stroke. Methods This study was a single-blinded, randomized controlled trial with a crossover design conducted at a single rehabilitation hospital. Patients (n = 19; 16 men, three women; mean age: 47.4 ± 11.6 years) with infratentorial stroke were randomly allocated to either group A (4 weeks of RAGT+CPT, followed by 4 weeks of CPT+CPT) or group B (4 weeks of CPT+CPT followed by 4 weeks of RAGT+CPT). Changes in dynamic and static balance as indicated by Berg Balance Scale scores were regarded as the primary outcome measure. Outcome measures were evaluated for each participant at baseline and after each 4-week intervention period. Results No significant differences in outcome-related variables were observed between group A and B at baseline. In addition, no significant time-by-group interactions were observed for any variables, indicating that intervention order had no effect on lower extremity function or balance. Significantly greater improvements in secondary functional outcomes such as lower extremity Fugl-Meyer assessment (FMA-LE) and scale for the assessment and rating of ataxia (SARA) were observed following the RAGT+CPT intervention than following the CPT+CPT intervention. Conclusion RAGT produces clinically significant improvements in balance and lower extremity function in individuals with infratentorial stroke. Thus, RAGT may be useful for patients with balance impairments secondary to other pathologies. Trial registration ClinicalTrials.gov Identifier NCT02680691.

Optochemogenetic Stimulation of Transplanted iPS-NPCs Enhances Neuronal Repair and Functional Recovery after Ischemic Stroke. J Neurosci 2019; 39:6571-6594. [PMID: 31263065 DOI: 10.1523/jneurosci.2010-18.2019] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Revised: 02/23/2019] [Accepted: 06/11/2019] [Indexed: 12/21/2022] Open
Abstract
Cell transplantation therapy provides a regenerative strategy for neural repair. We tested the hypothesis that selective excitation of transplanted induced pluripotent stem cell-derived neural progenitor cells (iPS-NPCs) could recapitulate an activity-enriched microenvironment that confers regenerative benefits for the treatment of stroke. Mouse iPS-NPCs were transduced with a novel optochemogenetics fusion protein, luminopsin 3 (LMO3), which consisted of a bioluminescent luciferase, Gaussia luciferase, and an opsin, Volvox Channelrhodopsin 1. These LMO3-iPS-NPCs can be activated by either photostimulation using light or by the luciferase substrate coelenterazine (CTZ). In vitro stimulations of LMO3-iPS-NPCs increased expression of synapsin-1, postsynaptic density 95, brain derived neurotrophic factor (BDNF), and stromal cell-derived factor 1 and promoted neurite outgrowth. After transplantation into the ischemic cortex of mice, LMO3-iPS-NPCs differentiated into mature neurons. Synapse formation between implanted and host neurons was identified using immunogold electron microscopy and patch-clamp recordings. Stimulation of transplanted cells with daily intranasal administration of CTZ enhanced axonal myelination, synaptic transmission, improved thalamocortical connectivity, and functional recovery. Patch-clamp and multielectrode array recordings in brain slices showed that CTZ or light stimulation facilitated synaptic transmission and induced neuroplasticity mimicking the LTP of EPSPs. Stroke mice received the combined LMO3-iPS-NPC/CTZ treatment, but not cell or CTZ alone, showed enhanced neural network connections in the peri-infarct region, promoted optimal functional recoveries after stroke in male and female, young and aged mice. Thus, excitation of transplanted cells via the noninvasive optochemogenetics treatment provides a novel integrative cell therapy with comprehensive regenerative benefits after stroke.SIGNIFICANCE STATEMENT Neural network reconnection is critical for repairing damaged brain. Strategies that promote this repair are expected to improve functional outcomes. This study pioneers the generation and application of an optochemogenetics approach in stem cell transplantation therapy after stroke for optimal neural repair and functional recovery. Using induced pluripotent stem cell-derived neural progenitor cells (iPS-NPCs) expressing the novel optochemogenetic probe luminopsin (LMO3), and intranasally delivered luciferase substrate coelenterazine, we show enhanced regenerative properties of LMO3-iPS-NPCs in vitro and after transplantation into the ischemic brain of different genders and ages. The noninvasive repeated coelenterazine stimulation of transplanted cells is feasible for clinical applications. The synergetic effects of the combinatorial cell therapy may have significant impacts on regenerative approach for treatments of CNS injuries.

Abstract
BACKGROUND Previous lower-limb mirror therapy research has focused on non-weight bearing interventions. OBJECTIVES The primary aim of this study was to investigate the effect and feasibility of a combination of mirror therapy and treadmill training on post-stroke lower-limb recovery compared to a placebo intervention. METHODS All patients (N = 30) walked on a treadmill for 30 min per day, 3 days per week, for 4 weeks. The mirror therapy and treadmill training group (n = 15) walked on the treadmill while viewing a reflection of their non-paretic limb in a mirror positioned in their mid-sagittal plane. The placebo group (n = 15) received no mirror visual feedback due to an altered mirror position. PRIMARY OUTCOME MEASURES Ten Metre Walk Test (10MWT) and Six Minute Walk Test (6MWT). SECONDARY OUTCOME MEASURES Modified Ashworth Scale (MAS) and Fugl-Meyer Assessment-Lower Extremity (FMA-LE). Feasibility was appraised by examining participant compliance and any adverse events. RESULTS No significant between group differences were demonstrated for the 10MWT, 6MWT or FMA-LE at post-training or 3-month follow-up assessment. A significant between group difference on the MAS was demonstrated in the reduction of ankle dorsiflexion muscle tone (p = 0.006) and ankle plantarflexion muscle tone (p = 0.01) in the mirror therapy group compared to the placebo group at post-training assessment but not at 3-month follow-up. CONCLUSION Our study reveals that in our group of patients with chronic stroke, mirror therapy combined with treadmill training facilitated significant reductions in ankle muscle tone (p < 0.05) compared to a placebo intervention.

Abstract
OBJECTIVE To determine the effects of inclusion of deep dry needling into a treatment session following the Bobath concept on spasticity, motor function and postural control after a stroke. METHODS 26 patients who had suffered a stroke were randomly assigned to one of two treatment groups: Bobath only, or Bobath plus dry needling. Both groups received a session including strengthening, stretching and reconditioning exercises following the principles of the Bobath concept. Patients in the Bobath plus dry needling group also received a single session of ultrasound-guided dry needling of the tibialis posterior. Spasticity (Modified Modified Ashworth Scale), function (Fugl-Meyer Scale) and stability limits (computerised dynamic posturography using the SMART EquiTest System) were collected before and 10 min after treatment by a blinded assessor. The parameters of the stability limits included movement velocity (MVL), maximum excursion (MXE), end-point excursion (EPE) and directional control (DCL). RESULTS A greater number of individuals receiving Bobath plus dry needling exhibited a decrease in spasticity after treatment (P<0.001). Analysis of covariance (ANCOVA) showed that patients receiving Bobath plus dry needling exhibited greater improvements in the balance (0.8, 95% CI 0.2 to 1.4), sensory (1.7, 95% CI 0.7 to 2.7) and range of motion (3.2, 95% CI 2.0 to 4.4) domains of the Fugl-Meyer Scale than those receiving Bobath only. ANCOVA also found that subjects receiving dry needling showed a greater increase in MVL non-affected forward direction, EPE non-affected direction, MXE backward and MXE affected/non-affected, DCL backward and DCL affected backward direction, than those who did not receive it. CONCLUSIONS The inclusion of deep dry needling into a treatment session following the Bobath concept was effective at decreasing spasticity and improving balance, range of motion and the accuracy of maintaining stability in patients who had experienced a stroke. TRIAL REGISTRATION NUMBER NCT02579291.

Abstract
BACKGROUND Robot-assisted ankle-foot-orthosis (AFO) can provide immediate powered ankle assistance in post-stroke gait training. Our research team has developed a novel lightweight portable robot-assisted AFO which is capable of detecting walking intentions using sensor feedback of wearer's gait pattern. This study aims to investigate the therapeutic effects of robot-assisted gait training with ankle dorsiflexion assistance. METHODS This was a double-blinded randomized controlled trial. Nineteen chronic stroke patients with motor impairment at ankle participated in 20-session robot-assisted gait training for about five weeks, with 30-min over-ground walking and stair ambulation practices. Robot-assisted AFO either provided active powered ankle assistance during swing phase in Robotic Group (n = 9), or torque impedance at ankle joint as passive AFO in Sham Group (n = 10). Functional assessments were performed before and after the 20-session gait training with 3-month Follow-up. Primary outcome measure was gait independency assessed by Functional Ambulatory Category (FAC). Secondary outcome measures were clinical scores including Fugl-Meyer Assessment (FMA), Modified Ashworth Scale (MAS), Berg Balance Scale (BBS), Timed 10-Meter Walk Test (10MWT), Six-minute Walk Test (SMWT), supplemented by gait analysis. All outcome measures were performed in unassisted gait after patients had taken off the robot-assisted AFO. Repeated-measures analysis of covariance was conducted to test the group differences referenced to clinical scores before training. RESULTS After 20-session robot-assisted gait training with ankle dorsiflexion assistance, the active ankle assistance in Robotic Group induced changes in gait pattern with improved gait independency (all patients FAC ≥ 5 post-training and 3-month follow-up), motor recovery, walking speed, and greater confidence in affected side loading response (vertical ground reaction force + 1.49 N/kg, peak braking force + 0.24 N/kg) with heel strike instead of flat foot touch-down at initial contact (foot tilting + 1.91°). Sham Group reported reduction in affected leg range of motion (ankle dorsiflexion - 2.36° and knee flexion - 8.48°) during swing. CONCLUSIONS Robot-assisted gait training with ankle dorsiflexion assistance could improve gait independency and help stroke patients developing confidence in weight acceptance, but future development of robot-assisted AFO should consider more lightweight and custom-fit design.

Abstract
BACKGROUND New evidence reveals significant metabolic changes in skeletal muscle after stroke. However, it is unknown if 31P magnetic resonance spectroscopy (31P-MRS) can evaluate these metabolic changes. Our objective here was to investigate: (a) if muscle energy metabolism changes in the affected side; (b) if muscle energy metabolism changes after rehabilitation; and (c) if energy metabolism measured by 31P-MRS can reflect changes in the Modified Modified Ashworth Scale (MMAS) and Fugl-Meyer assessment-lower extremity (FMA-LE) scores after rehabilitation. MATERIAL AND METHODS We enrolled 13 patients with stroke symptoms and hemiplegia. Lower-limb motor status on the affected side was evaluated by FMA-LE and MMAS. The 31P-MRS measures included phosphocreatine (PCr), inorganic phosphate (Pi), PCr/Pi, and pH. We statistically compared these measures in the affected and unaffected lower leg muscles before rehabilitation and after rehabilitation on the affected side. Spearman correlational analyses was performed to determine correlations between change in energy metabolism and change in FMA-LE score and MMAS score after rehabilitation. RESULTS PCr and PCr/Pi were significantly lower in the affected muscle compared to the unaffected muscle; however, there were no significant differences in Pi or pH. After rehabilitation, PCr, Pi, PCr/Pi, and pH did not significantly change. However, FMA-LE and MMAS score improved significantly after rehabilitation. Changes in energy metabolism measured by 31P-MRS had no correlation with FMA-LE change after rehabilitation. However, changes in PCr and PCr/Pi were correlated with change in MMAS score after rehabilitation. CONCLUSIONS 31P-MRS can evaluate changes in muscle energy metabolism in patients with stroke. PCr measured by 31P-MRS can reflect changes in MMAS after rehabilitation.

Abstract
Objective: To evaluate the effects of excitatory repetitive transcranial magnetic stimulation (rTMS) of the international 10–20 system P3 point (intraparietal sulcus region) in chronic patients with a frontal lesion and parietal sparing due to stroke on the impaired upper (UL) and lower limb (LL) as measured by the Fugl-Meyer Assessment (FMA). Methods: Three patients (C1: 49.83/2.75, C2: 53.17/3.83, C3: 63.33/3.08-years-old at stroke/years post-stroke, respectively) received two weeks (five days/week) of rTMS at 10 Hz of P3. A patient was treated in similar conditions with a sham coil (S1: 56.58/4.33). Patients were evaluated before, after, and two months post-treatment (A1, A2, and A3, respectively). Results: For LL, the scores of the motor function subsection of C1 and C3 as well as the sensory function of C2 increased by A2 and remained by A3. For UL, the score of the motor function of C2 and C3 also increased, but the score of C3 decreased by A3. The score of the range of motion subsection of C3 increased by the two follow-up evaluations. Conclusion: This study suggests excitatory rTMS over P3 may be of use for some chronic stroke patients, but these findings need to be verified in a future clinical trial.

Abstract
INTRODUCTION A large proportion of patients with chronic stroke have permanent lower limb functional disability leading to reduced levels of independent mobility. Individually, both mirror therapy and treadmill training have been shown to improve aspects of lower limb functioning in patients with stroke. This case report examined whether a new combination of both interventions would lead to improvements in lower limb functional disability for a patient with chronic stroke. CASE DESCRIPTION The participant was a 50-year-old female who had a left middle cerebral artery infarction (47 months' post stroke). Due to hemiparesis, she had lower limb motor impairment and gait deficits. INTERVENTION The participant engaged in a combination of mirror therapy and treadmill training for 30 minutes per day, 3 days per week, for 4 weeks. OUTCOMES Modified Ashworth Scale, Fugl-Meyer Assessment-Lower Extremity and the 10 m Walk Test demonstrated clinically meaningful change. The 6 Minute Walk Test did not demonstrate meaningful change. DISCUSSION The positive outcomes from this new combination therapy for this participant are encouraging given the relatively small dose of training and indicate the potential benefit of mirror therapy as an adjunct to treadmill training for enhancing lower limb muscle tone, motor function and walking velocity in patients with chronic stroke.

Abstract
Rehabilitation is the main therapeutic approach for reducing poststroke functional deficits in the affected upper limb; however, significant between-patient variability in rehabilitation efficacy indicates the need to target patients who are likely to have clinically significant improvement after treatment. Many studies have determined robust predictors of recovery and treatment gains and yielded many great results using linear approachs. Evidence has emerged that the nonlinearity is a crucial aspect to study the inter-areal communication in human brains and abnormality of oscillatory activities in the motor system is linked to the pathological states. In this study, we hypothesized that combinations of linear and nonlinear (cross-frequency) network connectivity parameters are favourable biomarkers for stratifying patients for upper limb rehabilitation with increased accuracy. We identified the biomarkers by using 37 prerehabilitation electroencephalogram (EEG) datasets during a movement task through effective connectivity and logistic regression analyses. The predictive power of these biomarkers was then tested by using 16 independent datasets (i.e. construct validation). In addition, 14 right handed healthy subjects were also enrolled for comparisons. The result shows that the beta plus gamma or theta network features provided the best classification accuracy of 92%. The predictive value and the sensitivity of these biomarkers were 81.3% and 90.9%, respectively. Subcortical lesion, the time poststroke and initial Wolf Motor Function Test (WMFT) score were identified as the most significant clinical variables affecting the classification accuracy of this predictive model. Moreover, 12 of 14 normal controls were classified as having favourable recovery. In conclusion, EEG-based linear and nonlinear motor network biomarkers are robust and can help clinical decision making.

Effects of Gait Training With Body Weight Support on a Treadmill Versus Overground in Individuals With Stroke. Arch Phys Med Rehabil 2016; 98:738-745. [PMID: 28034719 DOI: 10.1016/j.apmr.2016.11.022] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Revised: 11/16/2016] [Accepted: 11/21/2016] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To investigate the effects of gait training with body weight support (BWS) on a treadmill versus overground in individuals with chronic stroke. DESIGN Randomized controlled trial. SETTING University research laboratory. PARTICIPANTS Individuals (N=28) with chronic stroke (>6mo from the stroke event). INTERVENTIONS Participants were randomly assigned to receive gait training with BWS on a treadmill (n=14) or overground (n=14) 3 times a week for 6 weeks. MAIN OUTCOME MEASURES Gait speed measured using the 10-meter walk test, endurance measured using the 6-minute walk test, functional independence measured using the motor domain of the FIM, lower limb recovery measured using the lower extremity domain of the Fugl-Meyer assessment, step length, step length symmetry ratio, and single-limb support duration. Measurements were obtained at baseline, immediately after the training session, and 6 weeks after the training session. RESULTS At 1 week after the last training session, both groups improved in all outcome measures except paretic step length and step length symmetry ratio, which were improved only in the overground group (P=.01 and P=.01, respectively). At 6 weeks after the last training session, all improvements remained and the treadmill group also improved paretic step length (P<.001) but not step length symmetry ratio (P>.05). CONCLUSIONS Individuals with chronic stroke equally improve gait speed and other gait parameters after 18 sessions of BWS gait training on either a treadmill or overground. Only the overground group improved step length symmetry ratio, suggesting a role of integrating overground walking into BWS interventions poststroke.
