| 摘要 目的：研究C5和C6水平四肢瘫患者在4项日常生活活动中肌电活动的特点。方法：选择15例C5和C6水平的脊髓损伤患者，作为四肢瘫组，另选择15例正常人作为对照组。比较2组受试者在抓取杯子、触摸开关、驱动轮椅和支撑体重4项日常生活活动中8种肌肉的表面肌电活动强度。结果：与对照组相比，四肢瘫组在抓取杯子和驱动轮椅时，所有被测肌肉的相对EMG强度显著增大（P<0.01或P<0.05）；在触摸开关时，除背阔肌之外的所有其他肌肉的相对EMG强度显著增大（P<0.01）；在支撑体重的动作中，三角肌、肱二头肌、胸大肌和前锯肌的相对EMG强度显著增大（P<0.01或P<0.05），肱三头肌和背阔肌的相对EMG强度两组间差异无显著性（P>0.05）。结论：C5-6水平的四肢瘫患者可通过增加肌肉的动员水平来完成运动任务。

| Abstract: |
| Objective:To investigate the properties of electromyographic activities in patients with C5 and C6 quadriplegia during four activities of daily living(ADLs). Method：Fifteen patients with C5 and C6 spinal cord injury and fifteen healthy subjects formed a quadriplegia group and a control group respectively. The electromyographic data from eight muscles were recorded by surface electrodes and compared between two groups in four kinds of ADLs including grasping cup, touching lightswitch, wheelchair ambulation and upper limb weight-bearing. Result：Compared with control, the relative EMG intensities of all muscles in quadriplegia group were significantly higher during grasping cup and wheelchair ambulation（P<0.05 or P<0.01）; the relative EMG intensities of muscles except for latissimus dorsi during touching lightswitch and the relative EMG intensities of deltoid, biceps brachii, upper pectoralis and serratus anterior during upper limb weight-bearing were also significantly higher; however, no significant differences were found in triceps brachii and latissimus dorsi between the two groups during upper limb weight-bearing（P>0.05）. Conclusion：The results of this study indicated that C5—6 quadriplegic patients could increase motor level of muscles to complete motive tasks. |
