摘要
背景:颈肩痛是由颈肩部软组织(主要是肌肉)的慢性劳损所引起的常见临床症状。表面肌电图是一种新型、无创的肌肉活动检查手段,能测量肌肉的活动和功能。目的:评价颈肩疼痛患者颈肩部肌肉功能,为表面肌电图的应用和颈肩疼痛患者合理防治与康复提供理论依据。方法:应用表面肌电图对32例单侧颈肩疼痛的办公室工作人员在站立下,进行低头、头后伸、双手上举时颈竖脊肌、斜方肌上支的表面肌电测试。在测试前,对患者的颈肩疼痛进行目测类比评分。然后根据收集的数据,比较受试者颈肩部疼痛侧与非疼痛侧测试肌肉的肌电活动。结果与结论:测试前,受试者颈肩疼痛目测类比评分(平均分)为5.03分;受试者在低头、头后伸、双手上举过程中,其疼痛侧的颈竖脊肌、斜方肌上支的肌电原始信号较非疼痛侧的颈竖脊肌、斜方肌上支的肌电原始信号弱;疼痛侧颈竖脊肌、斜方肌上支肌电的平均振幅值与非疼痛侧相比差异有显著性意义(P<0.05);疼痛侧颈竖脊肌、斜方肌上支肌电的平均频率斜率值与非疼痛侧相比差异无显著性意义(P>0.05)。提示颈肩疼痛患者疼痛侧的颈肩肌肉的活动能力下降,长期坐位作业的办公室人员要定时进行颈肩部肌肉锻炼。
BACKGROUND: Pain of neck and shoulder is the common clinical symptoms caused by chronic strain of the neck and shoulder soft tissue (mainly muscle). Surface lectromyography is a new noninvasive examination method for muscle activity, which can measure the muscle activity and function. OBJECTIVE: To evaluate the neck-shoulder muscle function in patients with neck and shoulder pain, and provide theoretical basis for the application of surface electromyography and the reasonable prevention and rehabilitation of neck and shoulder pain. METHODS: Thirty-two office staffs with unilateral neck end shoulder pain were examined with surface electromyography, and the surface electromyographies of the neck erector muscle and trapezius muscle were recorded under the posture of lowering head, lifting head, and hands up. The visual analogue scales of neck and shoulder pain were recorded before the test. Then the data were collected, and the muscle electromyography activities were compared between the pain side and non-pain side. RESULTS AND CONCLUSION: The average visual analogue scales in patients with neck and shoulder pain was 5.03 before test. Under different postures, the original myoelectdcity signals of the neck erector muscle andtrapezius muscle in the pain side were weaker than that in the non-pain side; there were significant differences in the average amplitude value of the neck erector muscle and trapezius muscle between the pain side and the non-pain side (P 〈 0.05). No significant difference was found in the average frequency slope value of the neck s erector muscle and tmpezius muscle between the pain side and the non-pain side (P 〉 0.05). The results showed that, the neck and shoulder muscle activity ability decreased at the pain side of patients with neck and shoulder pain, and the office staffs with long-term seat assignments should exercise their neck and shoulder muscles regularly.
