Objective: To identify factors associated with earlier independence in "real-life walking" during hospitalization in subacute stroke patients., Design: Retrospective cohort study., Subjects/patients: Two hundred and six hemiplegic patients., Methods: Functional Independence Measure (FIM) walking items were measured biweekly from admission to discharge. Patients were grouped by achieving independent "real-life walking" (FIM-walking score ≥6). Time to independence, stratified by age, FIM motor score (FIM-M), FIM cognitive score (FIM-C), and Functional Ambulation Categories (FAC) scores were compared using Kaplan- Meier plots and log-rank tests. Hazard ratios were calculated via multivariable Cox proportional hazard models., Results: The median time to independence was 4 weeks, with significant differences (p < 0.05) by age, FIM-M, FIM-C, and FAC stratification. Age ≤64 years (hazard ratio 1.92, 95% confidence interval 1.21-3.06), FIM-C ≥25 (hazard ratio 2.42, 95% confidence interval 1.52-3.86), and FAC ≥3 (hazard ratio 1.98, 95% confidence interval 1.22-3.21) significantly affected earlier walking independence (all p < 0.01). Impeding factors were FIM-M ≤38 (hazard ratio 0.23, 95% confidence interval 0.13-0.40; p < 0.01) and FAC = 0 (hazard ratio 0.184, 95% confidence interval 0.06-0.62; p < 0.01)., Conclusion: Early improvement in "real-life walking" was associated with younger age, greater cognitive function, and greater "test-setting walking" ability on admission. Low activities of daily living independence and "test-setting walking" ability hindered early progress.

Introduction: Dose (number of repetitions) has been suggested as a key element in the effectiveness of rehabilitation exercises to promote motor recovery of the hemiparetic upper limb. However, rehabilitation exercises tend to be monotonous and require significant motivation to continue, making it difficult to increase the exercise dose. To address this issue, gamification technology has been implemented in exercises to promote self-engagement for people with hemiparesis in continuing monotonous repetitive movements. This study aimed to investigate how subjective perspectives, specifically enjoyability, motivation to continue, and expectancy of effectiveness, change through continuous daily exercise using a developed gamified exercise system., Materials and Method: Ten people with stroke suffering upper limb dysfunction underwent daily gamified exercise for seven days. The gamified exercise consisted of an electromyography (EMG)-controlled operating system that enabled users to play virtual games using repetitive finger movements. The participants performed conventional self-exercise on the same day as the control exercise, and rated their subjective perspectives on both exercises on a numerical rating scale on each exercise day., Results: Ratings for enjoyability and motivation to continue consistently showed significantly higher scores for the gamified exercise than for conventional self-exercise on all exercise days. A similar trend was observed in the ratings for the expectancy of effectiveness. No changes over time were found in any of the ratings throughout the exercise period., Conclusions: Exercise using the developed EMG-controlled gamified system may have the potential to maintain motivation and enjoyment in people with stroke to continue monotonous repetitive finger movements.

Factors affecting the efficiency of walking independence in patients with subacute stroke following robot-assisted gait training (RAGT) and conventional treatment (RAGT-CT) were examined. This retrospective cohort study included 37 patients with stroke [ n  = 11 ischemic; n  = 26 hemorrhagic; median poststroke interval, 28 days (interquartile range, IQR, 24-42)] who underwent RAGT using Welwalk for a median of 3 weeks (IQR, 2-4) followed by conventional training (median, 129 days; IQR, 114-146). The primary outcome was the change in functional independence measure (FIM)-walk item score from before to after RAGT (FIM-walk efficiency). The secondary outcome was the FIM-walk score at discharge. The independent variables included sensorimotor function [lower extremity (LE) motor and sensory scores and trunk function from the Stroke Impairment Assessment Set (SIAS) and Berg Balance Scale (BBS)] and cognitive function (FIM-cognitive, MMSE and Cognitive-related Behavioral Assessment) before RAGT-CT and RAGT dose duration per session, total steps and average treadmill speed at week 1, and number of sessions). We first determined the bivariate associations of each independent variable with the FIM-walk efficiency at the end of the RAGT period as decided by the therapists and with the FIM-walk score at discharge. Hierarchical multiple regression revealed that only the FIM-cognitive score was a significant predictor of the FIM-walk efficiency at the end of the RAGT period ( β  = 0.47; P  < 0.01, adjusted R2  = 0.21) after accounting for age, days post-stroke, SIAS-total lower extremity (SIAS-LE) motor score, and number of RAGT sessions (all nonsignificant). Furthermore, only the SIAS-trunk score was a significant predictor of the FIM-walk score at discharge ( β  = 0.52; P  < 0.01; adjusted R2  = 0.65) after accounting for age, days post-stroke, FIM-cognitive score, SIAS-LE motor score, and average treadmill speed at week 1 (all nonsignificant). Although patients with better cognition at the start of locomotor training achieved the pragmatic targets for terminating RAGT and proceeding with conventional therapy at a faster rate, the outcome at discharge is mainly dependent on early trunk function., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: The impact of different stroke types on specific activities of daily living (ADL) is unclear., Objective: To investigate how differences between intracerebral hemorrhage (ICH) and cerebral infarction (CI) affect improvement of ADL in patients with stroke within a hospital by focusing on the sub-items of the Functional Independence Measure (FIM)., Methods: Patients with first-stroke hemiplegia (n = 212) were divided into two groups: ICH (86 patients) and CI (126 patients). Primary assessments included 13 motor and 5 cognitive sub-items of the FIM assessed at admission and discharge. Between-group comparisons and multiple regression analyses were performed., Results: Upon admission, the ICH group exhibited significantly lower FIM scores than those of the CI group across various activities, including grooming, dressing (upper body and lower body), toileting, bed/chair transfer, toilet transfer, walking/wheelchair, and stairs. Age and FIM motor scores at admission influenced both groups' total FIM motor scores at discharge, whereas the duration from onset affected only the CI group., Conclusion: Several individual FIM motor items were more adversely affected by ICH than by CI. Factors related to ADL at discharge may differ depending on stroke type. Recognizing these differences is vital for efficient rehabilitation practices and outcome prediction.

Purpose: Movement repetition is known to play a key role in promoting functional improvements or maintaining functional levels in post-stroke hemiparetic patients. However, repetitive movements tend to be monotonous, making it challenging for patients to continue. Here, we developed a new gamified system to allow patients perform repetitive movements with enjoyment. The present study aimed to examine the usability of the system in subacute stroke patients., Method: The exercise system comprised an electromyography-controlled operating system that enabled users to play a virtual game by repetitive finger and wrist movements on the affected side. A total of 13 patients with upper-limb hemiparesis underwent a single bout of exercise using the system and assessed its usability, satisfactoriness, enjoyability, etc. using the System Usability Scale (SUS), Quebec User Evaluation of Satisfaction with assistive Technology (QUEST)-like questionnaire, and numerical rating scale (NRS)., Results: All the participants, who had a wide range of paretic levels, were able to perform the exercise using the system. Participants scored the system a median of 85.0 for SUS and 4.2 for the QUEST-like questionnaire, with an "excellent" in usability and "satisfied" in user satisfaction with the system. The median NRS scores for enjoyability, potential for continuous use, and effectiveness were 8.0, 9.0, and 9.0, respectively, which were greater than the scores for usual rehabilitation training for the upper extremity., Conclusions: The novel electromyography-controlled gamified exercise system may have sufficient usability and enjoyability to motivate patients with a wide range of paretic levels to perform repetitive finger and wrist movements.IMPLICATIONS FOR REHABILITATIONThe electromyography-controlled gamified exercise system had overall positive perspectives on the usability of the system.This exercise system could help motivate patients with a wide range of paretic levels to perform repetitive finger and wrist movements.

Purpose: The purpose of this study was to clarify whether the novel lateral transfer assist robot facilitates easier transfers compared with a wheelchair in post-stroke hemiparesis patients., Methods: This cross-sectional study enrolled 20 post-stroke hemiparesis patients, and the task difficulty of transfers was compared between a wheelchair and lateral transfer assist robot. All participants were asked to transfer from either wheelchair or lateral transfer assist robot to a platform table and back. The primary outcome was the transfer score of the Functional Independence Measure. The secondary outcome was the time required for transfer., Results: The transfer score of the Functional Independence Measure was significantly higher with lateral transfer assist robot than with wheelchair ( p  < .001). The transfer times from these devices to a platform table and back showed no significant differences (to device from platform table: 7.8 s, lateral transfer assist robot vs 7.6 s, wheelchair, p  > .05: device to platform table: 7.1 s, lateral transfer assist robot vs 8.0 s, wheelchair, p > .05)., Conclusions: Transfer with a lateral transfer assist robot is easier than with wheelchair and facilitates independence in post-stroke hemiparesis patients.IMPLICATIONS FOR REHABILITATIONTransfer skill influences the functional independence and quality of life of a wheelchair userA novel structural mobility device-the lateral transfer assist robot (LTAR)-can facilitate transfersThe LTAR could improve the degree of independence for transfers than the wheelchair, without any time loss, in post-stroke hemiparesis patientsThe LTAR could potentially reduce the risk for falls in various medical and care facilities.

Objective: Although studies on the efficacy of the rehabilitation robot are increasing, there are few reports using the robot for gait training in the actual clinical setting. This study aimed to investigate the effectiveness of gait training using Welwalk in hemiparetic stroke patients in a real clinical setting., Materials and Methods: This prospective study included 36 hemiparetic stroke patients who underwent gait training using Welwalk. We examined the walking ability improvement efficiency using Functional Independence Measure (FIM)-walk as the primary outcome, which was compared with that of 36 patients (matched control group) who underwent conventional rehabilitation. Other outcomes were the actual gait training period using Welwalk, raw FIM-walk score, lower extremity motor functions score in Stroke Impairment Assessment Set at discharge, and duration from stroke onset until discharge., Results: The improvement efficiency of the FIM-walk was significantly higher in the Welwalk group than in the matched control group (control 0.48 ± 0.31, Welwalk 0.80 ± 0.38, p-value < 0.001). The mean gait training period using Welwalk was 5 weeks. No significant differences were found in other outcomes between the Welwalk group and the matched control group., Conclusion: This study demonstrated the effectiveness of gait training using Welwalk on the improvement efficiency of the FIM-walk in hemiparetic stroke patients in an actual clinical setting., (Copyright © 2020 The Author(s).

Study Design: Single case report., Introduction: A previous study clarified that spasticity and motor function were improved by combined treatment with botulinum toxin type A (BTX) injection and 1-Hz repetitive transcranial magnetic stimulation (rTMS) with intensive motor training at 4 weeks after injection. However, it is not clear whether 1-Hz rTMS with intensive motor training immediately after BTX injection also improves spasticity and motor function in stroke patients., Purpose of the Case Report: The purpose of this case report is to test the short- and long-term effects of BTX injection and rTMS with intensive motor training on the spasticity, motor function, and usefulness of the paretic hand in a stroke patient., Methods: A 64-year-old male, who suffered from a right cerebral hemorrhage 53 months previously, participated in the present study. BTX was injected into the spastic muscles of the affected upper limb. He then received the new protocol for a total of 24 sessions. The Modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA), and Motor Activity Log, consisting of the amount of use and quality of movement scales, were assessed before and immediately after BTX injection, at discharge, and monthly for up to 5 months after discharge., Results: For the short-term effects of the therapy, the MAS scores of the elbow and wrist, FMA score, and quality of movement score improved. For the long-term effects of the therapy, the MAS score of the fingers, FMA score, and amount of use score improved for up to 5 months after discharge., Conclusions: The present case report showed the improvement of all assessments performed in the short and/or long term and suggest the possibility of shortening the intervention period of combined therapy of BTX and rTMS with intensive motor training., (Copyright © 2018 Hanley & Belfus.

Background Intensive motor training with low-frequency repetitive transcranial magnetic stimulation (rTMS) has efficacy as a therapeutic method for motor dysfunction of the affected upper limb in patients with mild to moderate stroke. However, it is not clear whether this combination therapy has the same effect in chronic post-stroke patients with severe upper limb motor impairment. Objectives The aim of this study was to test the treatment effects of intensive motor training with low-frequency rTMS in chronic post-stroke patients with severe upper limb motor impairment. Methods A convenience sample of 26 chronic post-stroke patients with severe upper limb motor impairment participated in this study with the non-randomized, non-controlled clinical trial. All subjects were hospitalized to receive intensive motor training with low-frequency rTMS. During 2 weeks in which Sundays were excluded, a total of 24 sessions (2 sessions per day) of the intervention were conducted. The Fugl-Meyer Assessment (FMA) and Wolf Motor Function Test (WMFT) were used to assess motor impairment and function of the affected upper limb, respectively, before and after intervention. Paired t-test was used to analyze the effects of the intervention. Results The FMA total score and WMFT log performance time significantly improved from before to after intervention (FMA: 12.6-18.0; WMFT: 3.6-3.3, p < 0.001). Conclusions The present results suggest that intensive motor training with low-frequency rTMS could improve motor impairment in chronic post-stroke patients with severe upper limb motor impairment and contribute to the expansion of the application range of this combination therapy.

Background: In a patient with severe hemiplegia, the risk of the knee giving way is high during the early stage of gait exercise with an ankle-foot orthosis. However, use of a knee-ankle-foot orthosis has many problems such as large amount of assistance and compensatory motions. To resolve these problems, we have engaged in the development of the Gait Exercise Assist Robot (GEAR)., Objective: To evaluate the improvement efficiency of walk with GEAR in a stroke patient., Methods: The subject was a 70-year-old man presented with left thalamus hemorrhage and right hemiplegia. The patient underwent exercise with the GEAR 5 days a week, for 40 minutes per day. We evaluated the Functional Independence Measure score for walk (FIM-walk score) every week. The control group consisted of 15 patients aged 20-75 years with hemiplegia after primary stroke, who had equivalent walking ability with the subject at start. As the primary outcome, we defined improvement efficiency of FIM-walk, which was gain of FIM-walk divided the number of required weeks., Results: Improvement efficiency of FIM-walk of the subject was 1.5, while that of control group was 0.48±3.2 (mean±SD)., Conclusions: GEAR is potentially useful for gait exercise in hemiplegic patients.

Background: Motor dysfunction after stroke might be improved by neuromuscular electrical stimulation (NMES) combined with 1 Hz repetitive transcranial magnetic stimulation (rTMS) in patients with moderate and severe motor dysfunction., Objective: This preliminary study tested the effect of this treatment combination., Methods: Fifteen patients (60.5 ± 10.3 years old) participated in the study. All patients had been affected by cerebral artery infarction or hemorrhage and had moderate or severe motor dysfunction in their affected hand. The patients received NMES at paretic wrist extensor muscles combined with rTMS over the unaffected M1 hemisphere twice a day, six days/week over two weeks. All participants underwent the following battery of tests to evaluate the motor function of the affected hand: Upper limb Fugl-Meyer Assessment (UFMA), Wolf Motor Function Test (WMFT), and Box and Block Test (BBT)., Results: UFMA, WMFT, and BBT scores improved significantly after the study., Conclusions: These results suggest that NMES combined with rTMS could be useful for recovery of moderate and severe motor function after stroke.

Objective: Research to examine the immediate effects of electrical stimulation combined with passive locomotion-like movement on gait velocity and spasticity., Design: A single-masked, randomized controlled trial design., Subjects: Twenty-seven stroke inpatients in subacute phase (ischemic n = 16, hemorrhagic n = 11)., Interventions: A novel approach using electrical stimulation combined with passive locomotion-like movement., Main Measures: We assessed the maximum gait speed and modified Ashworth scale before and 20 minutes after the interventions., Results: The gait velocity of the electrical stimulation combined with passive locomotion-like movement group showed the increase form 0.68 ± 0.28 (mean ± SD, unit: m) to 0.76 ± 0.32 after the intervention. Both the electrical stimulation group and passive locomotion-like movement group also showed increases after the interventions (from 0.76 ± 0.37 to 0.79 ± 0.40, from 0.74 ± 0.35 to 0.77 ± 0.36, respectively). The gait velocity of the electrical stimulation combined with passive locomotion-like movement group differed significantly from those of the other groups (electrical stimulation combined with passive locomotion-like movement versus electrical stimulation: P = 0.049, electrical stimulation combined with passive locomotion-like movement versus passive locomotion-like movement: P = 0.025). Although there was no statistically significant difference in the modified Ashworth scale among the three groups, six of the nine subjects (66.6%) in the electrical stimulation combined with passive locomotion-like movement group showed improvement in the modified Ashworth scale score, while only three of the nine subjects (33.3%) in the electrical stimulation group and two of the nine subjects (22.2%) improved in the passive locomotion-like movement group., Conclusion: These findings suggest electrical stimulation combined with passive locomotion-like movement could improve gait velocity in stroke patients.

Purpose: This study was designed to examine the effects of electrical stimulation combined with locomotion-like movement (ES/LM) for improving gait disorder in a stroke patient., Method: A four-phase ABAB single-subject design with five therapy sessions per phase was employed. In the intervention phases, transcutaneous electrical stimulation was applied to the tibialis anterior (at the end of the hip extension phase and in the initial hip flexion phase) and the soleus (in the initial hip extension phase) during passive hip flexion and extension. To assess improvement, the soleus H-reflex and the ambulatory function were measured (gait velocity and step length)., Results: Application of ES/LM resulted in a decrease of the soleus H-reflex and significant increase of gait velocity and step length., Conclusion: These findings suggest that ES/LM is a feasible treatment method for impaired ambulatory function in stroke patients at the subacute stage after the event.
