【摘要】：目的:观察脑卒中患者桥式运动下竖脊肌与多裂肌表面肌电(s EMG)信号变化特征,为桥式运动的临床应用提供电生理理论基础。方法:选取20例健康同龄成年人(正常组)与20例脑卒中偏瘫患者(患者组),对两组受试者行桥式运动时的竖脊肌与多裂肌s EMG信号参数进行比较分析。结果:1正常组双侧竖脊肌、多裂肌配对比较,时域指标平均肌电值(AEMG)、频域指标中位频率值(MF)均无显著性差异(P0.05);患者组竖脊肌患侧AEMG值大于健侧、患侧MF值均小于健侧,差异有显著性意义(P0.05);患者组双侧多裂肌AEMG值、MF值组内配对比较,差异无显著性意义。2两组受试者同侧竖脊肌与多裂肌AEMG值的比值差异无显著性意义(P0.05)。结论:桥式运动可作为脑卒中患者躯干肌训练的一种方法,但须注意训练时双侧竖脊肌的均衡性。
[Abstract]:Objective: to observe the changes of surface electromyography (SEMG) signal of erector spinal muscle and polyfissure muscle in stroke patients, and to provide a theoretical basis of electrophysiology for clinical application of bridge exercise. Methods: 20 healthy adults of the same age (normal group) and 20 stroke hemiplegic patients (patient group) were selected to compare and analyze the s EMG signal parameters of erector spinal muscle and polyfissure muscle during pontoon exercise in two groups. Results there was no significant difference in the mean time domain index (AEMG) and the median frequency value (MF) of the bilateral erector spinal muscle and the polyfissure muscle in the normal group (P0.05), the AEMG value of the affected side of the spinal muscle was higher than that of the healthy side, and the MF value of the affected side was lower than that of the healthy side, and the mean myoelectric value (AEMG) and the median frequency value (MF) of the frequency-domain index were not significantly different (P0.05). There was no significant difference in the ratio of AEMG between the two groups (P0.05), and there was no significant difference in the ratio of AEMG between the two groups (P0.05). Conclusion: bridging exercise can be used as a method of trunk muscle training in stroke patients, but we should pay attention to the balance of bilateral erector spinal muscles during training.
