ABSTRACT
BACKGROUND: The purpose of this study was to investigate the effects of real-time feedback methods on static balance training in stroke patients. There are two types of real-time feedback methods, as follows: one is Knowledge of Result (KR), and the other is Knowledge of Performance (KP). METHOD: Thirty stroke patients participated in this study and were randomly assigned to the KR group (n = 15) or the KP group (n = 15). All of the groups underwent real-time feedback training for four weeks (30 min per session, five sessions per week). The primary outcomes were sway length, sway velocity, and area 95%, which were assessed before and after the intervention. The secondary outcomes included the Berg Balance Scale, the Fugl Meyer Assessment for Lower Extremity, the Postural Assessment Scale for Stroke Trunk Impairment Scale, and the Fall Efficacy Scale. A group × time interaction was assessed using two-way ANOVA with repeated measures. RESULT: There was a significant increase over time in all outcomes (p < 0.05). Significant differences were observed for a group × time interaction in sway length and area 95% (p < 0.05). CONCLUSIONS: Real-time feedback training for static balance enhanced stroke patients' static balance abilities, clinical outcome assessments, and promoted self-efficacy against falls.
ABSTRACT
BACKGROUND: The incidence of work-related musculoskeletal disease is increasing despite automated manufacturing processes. OBJECTIVE: To examine the effect of a customized on-site exercise program on pain, posture, body function, body composition, and work-related health status of workers at an auto-parts factory. METHODS: Fifty-six participants were randomly divided into one of two groups: experimental (EG), which received a customized exercise program that included manual and exercise therapy from physiotherapy at the workplace; and control (CG), which received customized exercise sheets for a self-directed program at home. The program was performed 3 times per week for 12 weeks. Assessments were performed according to numerical rating scale (NRS), Exbody, Selective Functional Movement Assessment (SFMA), InBody, Short-Form-12 version 2 (SF-12v2), and Work Ability Index (WAI), which were evaluated before and after the program. RESULTS: The EG exhibited significant within-group changes in NRS, Exbody, SFMA, SF-12v2, and WAI; the CG exhibited significant within-group changes only in NRS and SFMA (pâ<â0.05). There were significant between-group differences in NRS, Exbody, SFMA, and WAI (pâ<â0.05). CONCLUSIONS: An on-site program including manual and exercise therapy directed by a physiotherapist among workers at an auto-parts manufacturer was effective in improving pain levels, posture, body function, and work-related health status.
