项目摘要

Repetitive voluntary motion of hemiplegic limb in physical training and motor learning are extremely important for the functional recovery of hemiplegic limbs. The purposes of this study were to study the effect of trans-cranial magnetic stimulation(TMS) on functional recovery of hemiplegia and motor learning.1)System was designed to combine the TMS and facilitation techniques. The trigger for beginning of the TMS was detected with laser light switch for the finger movements. Duration from the trigger to the TMS was designed to be variable. The finger movements were inducted using new designed system. Voltage of EMG evoked this system was bigger that in voluntary movement. The duration from the trigger to the finger movement and magnitude of TMS were studied.2)The summative effect of TNS and repetitive facilitation technique on functional recovery of hemiplegia was studied in three patients with chronic stroke. The functional recovery of hemiplegic limb were found in two of three patients3)The study presented here uses a Computerized Motor Skill Analyzer to examine motor learning tasks in the lower limbs. The normal task in the present study involved tracking a figure-eight with a foot marker. Following a limited practice session the subjects were required to perform a task involving mirror- or point-symmetry movement. This paradigm was used in order to elucidate the effect of motor learning obstruction, and revealed that while motor skills improved in the control group, no significant improvement was seen in the learning obstruction groups. Furthermore, the mirror image task impeded motor learning more than the point symmetry task.

偏瘫肢体在体育训练和运动学习中的重复随意运动对偏瘫肢体功能恢复至关重要。本研究旨在探讨经颅磁刺激（TMS）对偏瘫功能恢复和运动学习的影响。1）设计了一套将TMS与易化技术结合的联合收割机。通过手指移动的激光开关检测TMS开始的触发。从触发到TMS的持续时间设计为可变的。手指的运动是通过新设计的系统来引导的。诱发该系统的肌电图电压比随意运动时大。研究TNS和重复促通技术对3例慢性脑卒中患者偏瘫功能恢复的影响。3）本研究采用计算机运动技能分析仪对下肢运动学习任务进行了检测。在本研究中的正常任务涉及跟踪一个数字8与脚标记。在有限的练习之后，受试者被要求执行一项涉及镜像对称或点对称运动的任务。该范例用于阐明运动学习障碍的影响，并显示，虽然运动技能在对照组中得到改善，但在学习障碍组中没有看到显着改善。此外，镜像任务比点对称任务更阻碍运动学习。
