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 .
Improving Balance Skills in Patients Who Had Stroke Through Virtual Reality Treadmill Training
Objective : The aim of this study was to evaluate the effects of virtual reality ( VR ) treadmill training on the balance skills of patients who have had a stroke . Design : A total of 14 patients with strokes were recruited and r and omly assigned to receive VR treadmill or traditional treadmill training . The outcome measures that were included for the study were center of pressure ( COP ) sway excursion , COP maximum sway in anterior-posterior direction , COP maximum sway in medial-lateral direction , COP sway area , bilateral limb-loading symmetric index , the sway excursion values for the paretic foot ( sway excursion/P ) , paretic limb stance time ( stance time/P ) , number of steps of the paretic limb ( number of steps/P ) , and contact area of the paretic foot ( contact A/P ) during quiet stance , sit-to-st and transfer , and level walking . Results : There were no significant improvements in COP-related measures and symmetric index during the quiet stance , either in the VR treadmill or traditional treadmill training group ( P > 0.05 ) . However , the difference between groups after training in COP maximum sway in medial-lateral direction during the quiet stance was significant ( P = 0.038 ) . Traditional treadmill training failed to improve sit-to-st and performance , whereas VR treadmill training improved symmetric index ( P = 0.028 ) and sway excursion ( P = 0.046 ) significantly during sit-to-st and transfer . The changes of symmetric index between groups were markedly different ( P = 0.045 ) . Finally , both groups improved significantly in stance time/P , but only VR treadmill training increased contact A/P ( P = 0.034 ) after training during level walking . The difference between groups during level walking was not significant . Conclusions : Neither traditional treadmill nor VR treadmill training had any effect on balance skill during quiet stance , but VR treadmill training improved balance skill in the medial-lateral direction better than traditional training did . VR treadmill training also improved balance skill during sit-to-st and transfers and the involvement of paretic limb in level walking more than the traditional one did
