Abstract

[Purpose] The purpose of this study was to compare the effects of action observation training and motor imagery training on recovery from chronic stroke. [Subjects] Thirty patients (who were over six months post stroke) participated in this study and were randomly allocated to three groups. [Methods] The action observation training group practiced additional action observation training for five 30-minute sessions over a four-week period. The motor imagery training group practiced additional motor imagery training for five 30-minute sessions over a four-week period. Electroencephalogram were used to compare brain waves between the three groups. [Results] The action observation group showed significant changes in relative alpha power in Fp1 and Fp2 and relative beta power in Fp2 and C3. [Conclusion] Action observation induces higher levels of cognitive activities than motor imagery and physical training. Action observation is expected to be more effective for stroke patients.

摘要

[目的]本研究旨在比较动作观察训练和运动想象训练对慢性脑卒中恢复的影响。[对象]30例(脑卒中后超过6个月)患者参与了本研究,并被随机分为三组。[方法]动作观察训练组在四周内进行了五次30分钟的额外动作观察训练。运动想象训练组在四周内进行了五次30分钟的额外运动想象训练。使用脑电图比较三组之间的脑电波。[结果]动作观察组在Fp1和Fp2的相对阿尔法功率以及Fp2和C3的相对贝塔功率方面有显著变化。[结论]动作观察比运动想象和体育训练能诱导更高水平的认知活动。动作观察有望对脑卒中患者更有效。
