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

我们的目的是检查运动意象对中风偏瘫患者坐位平衡的影响。实验组分为运动想象结合运动训练的患者（I组）、只进行运动训练不进行运动想象的患者（M组）和不进行干预的对照组。在视觉信息的帮助下，I组患者被指示坐着并进行运动想象，就像他们向前弯曲躯干或向侧面弯曲躯干一样。在运动想象之后，他们被要求做与运动想象相同的动作。I组患者休息时患侧坐位压力明显增加，侧向患侧弯曲时运动角度明显增加。而M组患者与对照组相比无明显改善。提示运动想像对偏瘫患者的坐位平衡有一定的改善作用。

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.
