Background and objective . We devised a therapeutic approach to facilitate the use of hemiparetic upper extremity (UE) in daily life by combining integrated volitional control electrical stimulation with wrist splint, called hybrid assistive neuromuscular dynamic (HANDS). Methods. Twenty patients chronic stroke (median 17.5 months) had moderate severe UE weakness. Before immediately after completing 3 weeks training 40-minute sessions, 5 days per week over wearing system for 8 hours each...
Background An artificial intelligence (AI)-integrated electromyography (EMG)-driven robot hand was devised for upper extremity (UE) rehabilitation. This detects patients’ intentions to perform finger extension and flexion based on the EMG activities of 3 forearm muscles. Objective study aimed assess effect this in patients with chronic stroke. Methods a single-blinded, randomized, controlled trial 4-week follow-up period. Twenty were assigned active (n = 11) control 9) groups. Patients group...
Hybrid assistive neuromuscular dynamic stimulation (HANDS) therapy improved paretic upper extremity motor function in patients with severe to moderate hemiparesis. We hypothesized that brain machine interface (BMI) training would be able increase finger muscle activity enough apply HANDS hemiparesis, whose extensor was absent.The aim of this study assess the efficacy BMI followed by hemiparesis.Twenty-nine chronic stroke who could not extend their fingers were participated study. applied for...
Upper extremity rehabilitation in persons with stroke should be dose-dependent and task-oriented. Virtual reality (VR) has the potential to used safely effectively home-based rehabilitation. This study aimed investigate effects of virtual upper chronic stroke. was a single-blind, randomized, controlled trial conducted at two centers. The subjects were 14 outpatients more than 6 months after onset participants randomly divided into groups. intervention group (n = 7) performed home program for...
In post-stroke hemiparesis patients, the skeletal muscle mass decrease rapidly with histological degradation. We investigated effect of nutritional supplementation whey protein and vitamin D on quality, in convalescent rehabilitation patients a randomized, single-blinded, placebo-controlled trial. Fifty were randomly assigned to two groups; HP group received supplemental jelly (100 kcal; 10 g; 20 μg) twice day throughout up 16-week period, control placebo jelly. Cross-sectional area (CSA)...
Gait recovery is one of the primary goals stroke rehabilitation. independence a key functional component independent activities in daily living and social participation. Therefore, early prediction gait essential for Trunk function important gait, balance, lower extremity function. The Impairment Scale (TIS) was developed to assess trunk impairment patients with stroke.To evaluate predictive validity TIS acute stroke.A total 102 participated this study. Every participant assessed using TIS,...
Background and purpose: Trunk function plays a key role in performing activities of daily living (ADL) including locomotion sitting. Sitting ADL should be performed as early possible especially during the acute phase stroke rehabilitation. Therefore, this study aimed to assess trunk among patients with using Impairment Scale (TIS) predict its functional outcomes. Methods: Overall, 67 (i.e., within 2 days occurrence stroke) were included. The following clinical assessment items obtained 48 h...
Brain-machine interface training was developed for upper-extremity rehabilitation patients with severe hemiparesis. Its clinical application, however, has been limited because of its lack feasibility in real-world settings. We a new compact task-specific brain-machine system that enables training, including reach-and-grasp tasks, and studied effectiveness motor paralysis stroke.Prospective beforeâ€"after study.Twenty-six chronic hemiparetic stroke.Participants were trained the to pick up...
Abstract Post-stroke disability affects patients’ lifestyles after discharge, and it is essential to predict functional recovery early in hospitalization allow time for appropriate decisions. Previous studies reported important clinical indicators, but only a few indicators were analyzed due insufficient numbers of cases. Although review articles can exhaustively identify many prognostic factors, remains impossible compare the contribution each predictor. This study aimed determine which...
Objectives To investigate the construct validity of Trunk Impairment Scale (TIS), which was developed to assess trunk impairment in patients with stroke, Parkinson’s disease (PD). Design This retrospective, cross-sectional study enrolled consecutive PD inpatients. Correlation analysis performed clarify whether TIS assessment related other balance functions, lower extremity muscle strength, or walking ability. Factor see how background factors differ from function, limb and Results Examining...
Purpose:We hypothesized that recovery of upper extremity motor function is associated with reduction intracortical inhibition and improved reciprocal inhibition. This study examines the relationships functional in chronic stroke spinal Methods:Participants were 61 patients hemiparetic stroke. The participants applied hybrid assistive neuromuscular dynamic stimulation (HANDS) therapy for 3 weeks. Fugl-Meyer test score (FM) modified Ashworth scale (MAS) assessed before (T0), immediately after...
This study investigated the effects of a supervised home-based vestibular rehabilitation program using booklet on gait function and dizziness in patients with chronic peripheral hypofunction.This was non-blinded, randomized, controlled trial. Patients (n=42) hypofunction were randomly divided into group (VR group; n=20) or control (n=22). VR received addition to physician care for 4 weeks. The physical therapist checked home when visited outpatient clinic once week. only during trial period....
Stepwise linear regression (SLR) is the most common approach to predicting activities of daily living at discharge with Functional Independence Measure (FIM) in stroke patients, but noisy nonlinear clinical data decrease predictive accuracies SLR. Machine learning gaining attention medical field for such data. Previous studies reported that machine models, tree (RT), ensemble (EL), artificial neural networks (ANNs), support vector (SVR), and Gaussian process (GPR), are robust increase...
ObjectiveTo determine whether poststroke fatigue at admission is associated with the degree of independence in activities daily living patients stroke discharge from subacute rehabilitation wards.DesignRetrospective cohort study.SettingSubacute hospital.ParticipantsA consecutive sample (N=156) who were admitted to a ward between December 2012 and November 2013 enrolled study.InterventionsNot applicable.Main Outcome MeasuresPoststroke was assessed using Fatigue Severity Scale within 2 weeks...
Abstract Aim To investigate the cognitive function and its relation to home discharge of patients following subacute stroke. Methods This retrospective cohort study included 1,229 convalescent experiencing their first We determined destination demographic clinical information. recorded measurement scores: Mini-Mental State Examination (MMSE) score, Stroke Impairment Assessment Set grip strength, Functional Independence Measure (FIM). performed a multivariable logistic regression analysis...
Recently, surface electroencephalogram (EEG)-based brain-machine interfaces (BMI) have been used for people with disabilities. As a BMI signal source, event-related desynchronization of alpha-band EEG (8-13 Hz) during motor imagery (mu ERD), which is interpreted as desynchronized activities the activated neurons, commonly used. However, it often difficult patients severe hemiparesis to produce mu ERD sufficient strength activate BMI. Therefore, whether possible modulate anodal transcranial...
Background:Reciprocal inhibition (RI) may be important for recovering locomotion after stroke. Patterned electrical stimulation (PES) can modulate RI in a manner that could enhanced by voluntary muscle contraction (VC). Objective:To investigate whether VC enhances the PES-induced spinal pa tients with Methods:Twelve patients chronic stroke underwent three 20 min tasks, each on different days: (1) PES (10 pulses, 100 Hz every 2 s) applied to common peroneal nerve; (2) consisting of isometric...
A knee-ankle-foot orthosis (KAFO) prevents knee buckling during walking and enables gait training for acute hemiplegic stroke patients with severe disturbances. Although the goal of a KAFO is to improve ability, that is, acquire an ankle-foot (AFO), it not clear how contributes improving ability. Therefore, this study aimed investigate relationship between muscle activities improvement ability in disturbance.
