[Purpose] The purpose of this study was to investigate the effects of visual feedback training (VFT) in the sitting position on sitting balance ability and visual perception of chronic stroke patients. [Subjects] Twenty-two hospitalized subjects who had experienced a stroke more than six months earlier were included in this study. [Methods] Subjects in both the experimental group (n=12) and the control group (n=10) participated in a conventional rehabilitation program involving a 60-minute session five days per week for a period of four weeks. Subjects in the experimental group additionally practiced VFT 30-minute sessions, five days per week, for a period of four weeks. [Results] After the intervention, the experimental group showed significantly improved static sitting balance ability (left∙right, anterior∙posterior moment, and velocity moment), and dynamic sitting balance ability (anterior∙lateral moment). In visual perception tests, motor free visual perception test (MVPT) scores showed a significant increase of approximately 17% in the experimental group after the intervention. [Conclusion] The results of this study demonstrate the effectiveness of VFT in enhancing body function, as evidenced by improved sitting balance and visual perception of chronic stroke patients.

“…In this randomized controlled, single-blinded, pilot clinical trial in an inpatient rehabilitation hospital, 16 left hemiplegic patients with visual perceptional impairment were randomly assigned to receive either (1) participation in a computerized visual perception rehabilitation program with an interactive patient-computer interface applying motion tracking technology (CAMSHIFT) algorithm, or (2) use of the PSS CogRehab (Psychological Software Service, US) program for 3 sessions per week, 30 minutes per session for 4-weeks. There were 8 patients in each group [49]. The main measures were: Mini-Mental Status Examination, Motor-free Visual Perception Test and Modified Barthel Index were assessed at the beginning and end of the training.…”

SummaryBackgroundRecent review of the available evidence on interventions for motor recovery after stroke, showed that improvements in recovery of arm function were seen for constraint-induced movement therapy, electromyographic biofeedback, mental practice with motor imagery, and robotics. Similar improvement in transfer ability or balance were seen with repetitive task training, biofeedback, and training with a moving platform. Walking speed was improved by physical fitness training, high-intensity physiotherapy and repetitive task training. However, most of these trials were small and had design limitations.Material/MethodsIn this article, randomized control trials (RCT’s) published in 2009 of rehabilitation therapies for acute (≤2 weeks), sub-acute (2 to 12 weeks) and chronic (≥12 weeks) stroke was reviewed. A Medline search was performed to identify all RCT’s in stroke rehabilitation in the year 2009. The search strategy that was used for PubMed is presented in the Appendix 1. The objective was to examine the effectiveness of these treatment modalities in stroke rehabilitation.ResultsThis generated 35 RCT’s under 5 categories which were found and analyzed. The methodological quality was assessed by using the PEDro scale for external and internal validity.ConclusionsThese trials were primarily efficacy studies. Most of these studies enrolled small numbers of patient which precluded their clinical applicability (limited external validity). However, the constraint induced movement therapy (CIT), regularly used in chronic stroke patients did not improve affected arm-hand function when used in acute stroke patients at ≤4 weeks. Intensive CIT did not lead to motor improvement in arm-hand function. Robotic arm treatment helped decrease motor impairment and improved function in chronic stroke patients only. Therapist provided exercise programs (when self-administered by patients during their off-therapy time in a rehabilitation setting) did improve arm-hand function. Tai Chi exercises helped improve balance and weight bearing. Exercise programs for community dwelling stroke patient helped maintain and even improve their functional state.
