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 .
Balance performance with a cognitive task: a dual-task testing paradigm.
PURPOSE Athletic performance dem and s simultaneous use of cognitive and postural control capabilities . Decrements to both systems have been observed following concussion . This study evaluated a dual-task methodology to establish the tenability of using this testing model in concussed athletes . METHODS Nonconcussed subjects were assessed over 2 d. Subjects were introduced to the task-switching cognitive assessment test and a NeuroCom Smart Balance Master postural control assessment protocol on day 1 . In the following session , subjects were evaluated on  postural control and cognitive function tests independently ( single task ) , and then concurrently ( dual task ) . RESULTS Significant improvements were seen in three of the four balance conditions and in three of the four reaction times when the cognitive and balance task were performed simultaneously ( P<0.05 ) . No significant balance by cognitive task interaction was revealed ( P>0.05 ) ; however , significant differences existed in reaction time based on stimulus position and increasing balance dem and s ( P<0.05 ) . CONCLUSION Combining the cognitive and balance assessment s result ed in healthy subjects showing improved performance when compared with individual task performance . The dual-task methodology brought about systematic changes to reaction time in relation to increasing balance dem and s. The ability of this protocol to detect changes in postural control or cognitive function following concussive injury requires further study
