Objectives: To examine the test-retest reliability, calculate minimal detectable change (MDC), and report internal consistency of the Test of Visual Perceptual Skills-Third Edition (TVPS-3) in patients with stroke., Design: Repeated-measures design (at an interval of 2wk)., Setting: Medical center., Participants: Patients (N=50) with chronic stroke who completed the TVPS-3., Interventions: Not applicable., Main Outcome Measures: TVPS-3 that contains 7 subscales, namely, visual discrimination, visual memory, spatial relations, form constancy, sequential memory, visual figure-ground, and visual closure., Results: The intraclass correlation coefficient value of the overall scale was .92 and those of the 7 subscales were .53 to .82. The MDC values of the overall scale and the subscales were 18.1 and 5.4 to 7.1, respectively. The MDC% value of the overall scale was 16.2% (<30%), showing acceptable random measurement error. However, the MDC% values of the subscales were 33.7% to 44.1% (>30%), indicating substantial random measurement errors. The Cronbach α of the 7 subscales were .71 to .89, indicating good internal consistency., Conclusions: Our results showed that the overall scale of the TVPS-3 had satisfactory test-retest reliability. However, the subscales demonstrated insufficient test-retest reliability. Therefore, the subscales should be used cautiously to explain the test results over repeated assessments in patients with stroke., (Copyright © 2016 American Congress of Rehabilitation Medicine.

Objective: To compare the effects of exergaming with conventional weight-shift training on balance function in patients with chronic stroke., Design: Single-blind randomized controlled trial., Setting: Medical center., Participants: Patients (N=30) with chronic stroke and balance deficits., Interventions: Twelve weeks of Wii Fit training or conventional weight-shift training., Main Outcome Measures: Static balance was assessed using posturography. We recorded the stability index and percentage of weight bearing on the affected leg in 8 positions. We also used the timed Up and Go and forward reach tests for dynamic balance evaluation, Falls Efficacy Scale-International for fear of falling assessment, and Physical Activity Enjoyment Scale for estimating the enjoyment of training., Results: The exergaming group showed more improvement in stability index than the control group in head straight with eyes open while standing on a foam surface, eyes closed while standing on a solid surface with head turned 30° to the left, and eyes closed while standing on a solid surface with head turned up positions (time-group interaction P=.02, .04, and .03, respectively); however, the effects were not maintained. At 3-month follow-up, the control group showed more improvement in weight-bearing symmetry in the head straight with eyes open while standing on a solid surface position than the exergaming group (time-group interaction P=.03). Both groups showed improvement in the timed Up and Go test, forward reach test, and fear of falling. The improvement in fear of falling was not maintained. The exergaming group enjoyed training more than the control group (P=.03)., Conclusions: Exergaming is enjoyable and effective for patients with chronic stroke., (Copyright © 2014 American Congress of Rehabilitation Medicine.
