摘要
目的探讨本体感觉神经肌肉促进技术(PNF)对于脑卒中患者下肢运动功能的影响及其作用机制。方法采用随机采样,横断面的设计来评价44例脑卒中患者接受PNF收缩-放松-拮抗肌收缩(PNF-CRAC)技术训练前后患者膝关节肌肉的sEMG信号。结果PNF-CRAC技术具有很好的兴奋扩散作用,可以提高脑卒中患者患膝主动肌的兴奋性和运动控制能力。结论PNF-CRAC技术增加膝关节的稳定性,促进偏瘫下肢运动功能的恢复。
Objective To examine the effects of proprioceptive neuromuscular facilitation(PNF) techniques on lower limb motor function of strokes and its mechanism. Methods We used simple random sampling and cross-section survey design. PNF Contract Relax Agonist Contract(PNF-CRAC) techniques were applied to 44 stroke patients. Surface electromyography values(sEMG) was recorded from rectus femoris and hamstring of stroke patients with both low limbs. Results PNF-CRAC techniques not only caused the irradiation of muscles activities in the contralateral extremity during unilateral exercise, but also increased agonist EMG activities and the motor control of knee joint in strokes. Conclusion PNF-CRAC techniques can improve the knee stability and enhance the recovery of motor function in paretic lower limb.
