Complex Skill Training Transfers to Improved Performance and Control of Simpler Tasks After Stroke.

摘要: Background Given limited therapy time, it is important to practice tasks that optimize transfer other cannot be practiced during therapy. However, little known about how can selected for generalization. Objective One dimension of task selection the complexity task. The purpose current study was test if learning a complex motor skill with paretic arm would simpler unpracticed goal-directed reaching Design This an observational study, repeated measures design. Methods Fifteen participants mild-to-moderate stroke using their 2 consecutive days. Complex quantified change in speed-accuracy trade-off from baseline 1 day and month post-practice. Motor assessed as planar performance kinematics baselines Nine additional were recruited test-alone group who only participated tests rule out effects testing. Results Practice improved retained over period month. Importantly, practice, but not testing alone, long-term Improvements (reaching) strongly correlated improvements skill. Limitations We did have comparison task-specific movements. Conclusions number therapy, training may added advantage performance.
