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 .
Dual-task exercise improves walking ability in chronic stroke: a randomized controlled trial.
OBJECTIVE To examine the effectiveness of a dual-task-based exercise program on walking ability in subjects with chronic stroke . DESIGN Single-blind r and omized controlled trial . SETTING General community . PARTICIPANTS Twenty-five subjects with chronic stroke who were at least limited community ambulatory subjects ( a minimum gait velocity , 58cm/s ) . INTERVENTIONS Participants were r and omized into a  control group ( n=12 ) or experimental group ( n=13 ) . Subjects in the control group did not receive any rehabilitation training . Subjects in the experimental group underwent a 4-week ball exercise program . MAIN OUTCOME MEASURES Gait performance was measured under single task ( preferred walking ) and tray-carrying task . Gait parameters of interest were walking speed , cadence , stride time , stride length , and temporal symmetry index . RESULTS The experimental group showed significant improvement in all selected gait measures except for temporal symmetry index under both task conditions . In the control group , there were no significant changes over the 4-week period for all selected measures . There was a significant difference between groups for all selected gait variables except for temporal symmetry index under both task conditions . CONCLUSIONS The dual-task-based exercise program is feasible and beneficial for improving walking ability in subjects with chronic stroke
