目的：探讨脑卒中患者坐位下竖脊肌、腹直肌的表面肌电信号与坐位平衡的关系。
方法：收集脑卒中患者15例为试验组，健康人15例为对照组。测试过程：①受试者均在平衡仪（Teconbody,PK245）上进行坐位平衡测试，睁眼30s和闭眼30s，记录平衡仪参数（重心摆动长度、面积、X轴压力中心、Y轴压力中心）；②受试者坐于平衡仪上，前后最大范围的进行腰背屈伸活动，在此同时用表面肌电（MEGA-6000）对双侧竖脊肌、腹直肌进行测试，通过肌电值原始数据分析计算出测试肌肉的对称指数。
结果：在睁眼和闭眼坐位及坐位下前后最大范围运动时，脑卒中患者竖脊肌的对称指数比健康人的对称指数大，且差异均存在显著性意义（P<0.05）；而腹直肌的对称指数组间比较无差异性（P>0.05）。平衡仪参数与肌电信号的对称指数无显著相关性。
结论：脑卒中患者坐位下躯干肌两侧存在不平衡性，但是竖脊肌、腹直肌肌电信号激活的程度对坐位平衡功能无直接影响。 |

| Abstract
Objective: To investigated the relationship between the SEMG symmetry of trunk muscle and the balance function during eye open and close and trunk flex and extent at sitting position, and explore the difference between stroke patients and healthy.
Method: 15 stroke patients and 15 healthy individuals were collected. Testing process: ①all subjects sat on the force platform balance system(Teconbody PK245) with eye open 30s and eye close 30s consequently, the instrument parameters(center of gravity swing length, area, the X axis and Y axis pressure center) and the surface EMG activities of bilateral spinal erector and the rectus abdominis with the surface electromyograph (MEGA-6000) were recorded at the same time; ②The subjects sat on the balance instrument with the largest range of trunk flexion and extension consequently, the instrument parameters and the surface EMG activities were recorded at the same time as for eye open and eye close. The correlation coefficients of symmetry index of SEMG and the imbalance parameters were analyzed.
Result: As the eye open and close and the trunk maximum flex and extent, the symmetric index of erector spinal muscle were statistically significant higher in stroke patients than in healthy controls(P<0.05), but not for rectus abdominis.There was no significant correlation between the equilibrium parameters and the symmetric index for both muscles except the XCOP to symmetric index of spinal erector as eye open and close.
Conclusion: The SEMG activity of bilateral spinal erector and rectus abdominis is imbalance as sitting for stroke patient. But the imbalance did not influence subject’s balance directly. |
