The effect of visual information of another person's movement to the impairement of relaxing muscle contraction after stroke.

中风后运动性轻瘫的患者通常在适当释放肌肉收缩的能力方面受损。当患者主动移动患肢时，使控制患肢的肌肉逐渐共同收缩。模仿学习是一种有效的运动技能学习策略，学习者通过观察他人的动作来获得应该学习的信息。在这里，我将这种模仿运动应用于释放肌肉收缩的损伤。与自主运动相比，受试者重复进行手指伸屈运动时，模仿运动的共同收缩程度较小。

Patients with motor paresis after stroke have often impaired in the ability to release the muscle contraction appropriately. And then this causes the muscles controlling parleyed limb to get co-contracted gradually while the patients move the parlayed limb voluntarily. Imitation learning is one of the effective motor learning strategy where a learner get information that should be learned from observing the movements performed by another person. Here I applied this imitation movement to the impairment in release muscle contraction. Compared with the voluntary movements, the imitation movement had got less co-contracted while the subjects repeated in performing finger extension-flexion movement.
