Cognitive motor interference is effective for improving gait and balance function for stroke in the short term .
However , only little evidence supports assumptions regarding CMI 's long-term benefits
BACKGROUND AND PURPOSE An increasing interest in the potential benefits of cognitive motor interference ( CMI ) for stroke has recently been observed , but the efficacy of CMI for gait and balance is controversial .
A systematic review and meta- analysis of r and omized controlled trials was performed to estimate the effect of CMI on gait and balance in patients with stroke .
Use of Virtual Reality to Enhance Balance and Ambulation in Chronic Stroke: A Double-Blind, Randomized Controlled Study
Kim JH , Jang SH , Kim CS , Jung JH , You JH : Use of virtual reality to enhance balance and ambulation in chronic stroke : A double-blind , r and omized controlled study . Objective : To examine an additive effect of virtual reality on balance and gait function in patients with chronic hemiparetic stroke . Design : Twenty-four adults with hemiparetic stroke were r and omly assigned to either an experimental group ( n = 12 ) or a control group . Both groups underwent conventional physical therapy , 40 mins a day , 4 days a week for 4 wks . The experimental group received an additional 30 mins of virtual reality therapy each session . Balance performance was determined by the Balance Performance Monitor and Berg Balance Scale tests . Gait performance was determined by the 10-m walking test and Modified Motor Assessment Scale , and spatiotemporal parameters were obtained using GAITRite . Analysis of variance and correlation statistics were performed at P < 0.05 . Results : In the balance test , the experimental group had improved Berg Balance Scale scores , balance and dynamic balance angles ( ability to control weight shifting ) compared with the controls ( P < 0.05 ) . In the gait performance test , the experimental group showed significant improvements in velocity , Modified Motor Assessment Scale scores , cadence , step time , step length , and stride length ( P < 0.05 ) . Improvement in dynamic balance angles was correlated with velocity and cadence ( P < 0.01 ) . Conclusions : This study demonstrates that virtual reality has an augmented effect on balance and associated locomotor recovery in adults with hemiparetic stroke when added to conventional therapy
