Effects of Motor Imagery Combined with Repetitive Task Practice on Sitting Balance of Hemiplegic Patients

本研究旨在探讨运动想象对中风偏瘫患者坐位平衡的影响。实验组包括接受运动想象和运动训练的患者（I组）、只接受运动训练而不接受运动想象的患者（M组）和不接受干预的对照组患者。I组患者在视觉信息的辅助下，以躯干前屈或躯干侧屈的姿势进行坐位运动想象。在运动想象之后，他们被要求执行与运动想象相同的动作。I组患者静息时患侧坐位压力显著增加，向患侧屈时运动角度显著增加。然而，与对照组相比，M组的患者没有显示出显著改善。这些结果表明，运动想象对偏瘫患者的坐位平衡是有效的。

We aimed at examining effects of motor imagery on sitting balance in hemiplegic patients with stroke. The experimental group consisted of patients who received motor imagery combined with movement training (I group), patients who received only movement training without motor imagery (M group) and control patients without intervention. The patients in I group were instructed to sit and perform motor imagery as if they flexed trunk forward or bent their trunk laterally, with the aid of visual information. After motor imagery, they were asked to perform the same movement as motor imagery. Sitting pressure in affected side at rest was significantly increased, and the angles of movements were significantly increased while bending laterally to affected side in I group. However, the patients in M group showed no significant improvement compared to the patients in control group. These results indicate that motor imagery was effective on sitting balance of hemiplegic patients.
