To explore motor performance on 2 different cognitive tasks during robotic rehabilitation in which motor performance was longitudinally assessed.
Prospective study.
Rehabilitation hospital.
Patients (N=22) with chronic stroke and upper extremity impairment.
A total of 640 repetitions of robot-assisted planar reaching, 5 times a week for 4 weeks.
Longitudinal robotic evaluations regarding motor performance included smoothness, mean velocity, path error, and reach error by the type of cognitive task. Dual-task effects (DTEs) of motor performance were computed to analyze the effect of the cognitive task on dual-task interference.
Cognitive task type influenced smoothness (P=.006), the DTEs of smoothness (P=.002), and the DTEs of reach error (P=.052). Robotic rehabilitation improved smoothness (P=.007) and reach error (P=.078), while stroke severity affected smoothness (P=.01), reach error (P<.001), and path error (P=.01). Robotic rehabilitation or severity did not affect the DTEs of motor performance.
The results provide evidence for the effect of cognitive-motor interference on upper extremity performance among participants with stroke using a robotic-guided rehabilitation system.
探讨在机器人辅助康复过程中，在两项不同认知任务下的运动表现，并对运动表现进行纵向评估。
前瞻性研究。
康复医院。
22例患有慢性中风且上肢功能受损的患者。
总共进行640次机器人辅助的平面伸展动作，每周5次，共4周。
关于运动表现的纵向机器人评估包括认知任务类型的平滑度、平均速度、路径误差和伸展误差。计算运动表现的双任务效应（DTEs），以分析认知任务对双任务干扰的影响。
认知任务类型影响平滑度（P = 0.006）、平滑度的双任务效应（P = 0.002）和伸展误差的双任务效应（P = 0.052）。机器人辅助康复改善了平滑度（P = 0.007）和伸展误差（P = 0.078），而中风严重程度影响平滑度（P = 0.01）、伸展误差（P < 0.001）和路径误差（P = 0.01）。机器人辅助康复或严重程度并未影响运动表现的双任务效应。
研究结果为使用机器人引导康复系统的中风参与者中认知 - 运动干扰对上肢表现的影响提供了证据。
