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 .
Effects of virtual reality training on gait biomechanics of individuals post-stroke.
OBJECTIVE To evaluate gait biomechanics after training with a virtual reality ( VR ) system and to eluci date underlying mechanisms that contributed to the observed functional improvement in gait speed and distance . DESIGN A single blind r and omized control study . SETTING Gait analysis laboratory in a rehabilitation hospital and the community . PARTICIPANTS Fifteen men and three women with hemiparesis caused by stroke . INTERVENTIONS Subjects trained on a six-degree of freedom force-feedback robot interfaced with a VR simulation . Subjects were r and omized to either a VR group ( n=9 ) or non-VR group ( NVR , n=9 ) . Training was performed three times a week for 4 weeks for approximately 1h each visit . MAIN OUTCOME MEASURES Kinematic and kinetic gait parameters . RESULTS Subjects in the VR group demonstrated a significantly larger increase in ankle power generation at push-off as a result of training ( p=0.036 ) . The VR group had greater change in ankle ROM post-training ( 19.5 % ) as compared to the NVR group ( 3.3 % ) . Significant differences were found in knee ROM on the affected side during stance and swing , with greater change in the VR group . No significant changes were observed in kinematics or kinetics of the hip post-training . CONCLUSIONS These findings are encouraging because they support the potential for recovery of force and power of the lower extremity for individuals with chronic hemiparesis . It is likely that the effects of training included improved motor control at the ankle , which enabled the cascade of changes that produced the functional improvements seen after training
