【摘要】：目的研究脑卒中患者在平衡仪上进行平衡测试时,竖脊肌、腹直肌肌电信号变化的特征,并观察其平衡功能。方法 2015年4月至2016年12月,脑卒中患者17例(试验组)和健康受试者13例(对照组)在平衡仪上坐位进行三种运动:睁眼/闭眼、平衡仪前后摆动10°、最大范围前后屈伸躯干。利用表面肌电记录运动时双侧竖脊肌和腹直肌肌电信号的均方根(RMS),记录受试者睁眼/闭眼坐位时质心摆动长度、质心摆动面积、X轴压力中心和Y轴压力中心。结果试验组在闭眼/睁眼坐位、最大范围前后屈伸运动时,竖脊肌RMS健侧与患侧间有显著性差异(t2.173,P0.05)。与对照组比较,试验组睁眼/闭眼坐位下健侧竖脊肌和腹直肌RMS增加(t2.175,P0.05),质心摆动长度及面积均增加(t2.760,P0.05)。结论脑卒中患者竖脊肌易出现两侧肌力不平衡,从而影响患者的平衡功能,康复训练时要加以重视。
[Abstract]:Objective to study the changes of the electrical signals of erector spinal muscle and rectus abdominis in stroke patients and to observe their balance function. Methods from April 2015 to December 2016, 17 stroke patients (test group) and 13 healthy subjects (control group) underwent three kinds of exercises on the balance instrument: open eyes / eyes closed, balance instrument swinging 10 掳back and back, and maximal range of trunk flexion and extension. The root-mean-square (RMS) of bilateral vertical spinal muscle and rectus abdominis were recorded by surface electromyography. The swinging length of center of mass, the area of swinging area of center of mass and the pressure center of Y-axis were recorded. Results in the experimental group, there was a significant difference between the contralateral side and the affected side of the erector spinal muscle in the position of eye closure / eye opening and the maximum range of flexion and extension (t 2.173 P 0.05). Compared with the control group, the RMS of contralateral erector spinal muscle and rectus abdominis muscle were increased (t2.175), and the wobble length and area of mass center were increased in the experimental group (t2.760). Conclusion bilateral muscle imbalance is easy to occur in patients with cerebral apoplexy, which affects the balance function of patients and should be paid more attention to in rehabilitation training.
