Abstract

Mental practice (MP) consists of the repeated mental rehearsal of a physical skill without movement, called motor imagery (MI). Studies show that MP and MI associated mirror therapy (MPMT) may improve muscle control of the upper limbs in hemiparesis. This study aimed to evaluate muscle activation during active flexion of the wrist (MA), MP, and MPMT in patients with history of stroke and hemiparesis. Individuals diagnosed with stroke showing sequelae of upper limb hemiparesis were enrolled. The flexor carpi ulnaris was analyzed using electromyography during tasks (MA, MP, MPMT) involving wrist flexion. Greater electromyographic activity was detected during MP and MPMT techniques compared to active movement (p = 0.02). There was no significant difference between MP and MPMT (p = 0.56). These results were found in both the affected limb and unaffected limb. Immediate effects on muscle activation are experienced during MP and MPMT, and muscle activity was similar with both therapies.

摘要

心理练习（MP）包括在不进行动作的情况下对身体技能进行反复的心理演练，即所谓的运动想象（MI）。研究表明，心理练习和与运动想象相关的镜像疗法（MPMT）可能会改善偏瘫患者上肢的肌肉控制。本研究旨在评估有中风病史和偏瘫的患者在主动腕关节屈曲（MA）、心理练习和MPMT过程中的肌肉激活情况。纳入了被诊断为中风且有上肢偏瘫后遗症的个体。在涉及腕关节屈曲的任务（MA、MP、MPMT）期间，使用肌电图分析尺侧腕屈肌。与主动运动相比，在心理练习和MPMT技术过程中检测到更大的肌电活动（p = 0.02）。心理练习和MPMT之间没有显著差异（p = 0.56）。在患侧肢体和未患侧肢体中均发现了这些结果。在心理练习和MPMT过程中会立即体验到对肌肉激活的影响，并且两种疗法的肌肉活动相似。
