针刺对肩周炎患者三角肌表面肌电信号的影响

Effect on surface electromyography of deltoid in periarthritis patients under acupuncture stimulation

目的:通过观察肩周炎患者针刺前后特定穴位表面肌电变化,探索针刺疗效的客观评价指标。方法:对26例肩周炎患者采用针刺肩髃、肩前、肩髎、臂臑穴,隔天1次,共治疗6次。用肌电仪对患者针刺前后及各穴行针5s时三角肌的肌电值进行采集,将数据统计、分析。结果:与治疗前三角肌表面肌电值比较,肩前穴第2、3、5次行针时、臂臑穴第2、3、6次行针时及肩髃穴6次行针时肌电值均有明显变化(均P<0.05),肩髎穴6次行针时肌电值均无明显变化(均P>0.05)。6次针刺治疗前后三角肌表面肌电值差异均有统计学意义(均P<0.05)。结论:针刺对于三角肌表面肌电值有一定影响,其中肩髃穴最为显著,肩前穴、臂臑穴次之,肩髎穴无明显影响。

Objective To explore the objective evaluation index of acupuncture effect through study on the differences of surface electromyography of deltoid before and after acupuncture at some specific points. Methods Twenty-six cases of periarthritis were treated with acupuncture at Jianyu （LI 15）, Jianqian （Extra）, Jianliao （TE 14） and Binao （LI 14）. The treatment was given once every other day, six treatments were required. The deltoid myoelectricity indices were collected and analyzed before treatment, after treatment and after 5 s manipulations at each acupoint. Results Compared with the deltoid myoelectricity before treatment, there were statistically significant differences in the 2nd, 3rd and 5th manipulations during the acupuncture stimulation at Jianqian （Extra）, the 2nd, 3rd and 6th manipulations at Binao （ LI 14） （all P〈0.05） and all the 6 manipulations at Jianyu （LI 15） （all P〈0.05）. However, there was no statistically significant difference in all the 6 manipulations at Jianliao （TE 14） （all P〈0.05）. And the differences of deltoid surface myoelectricity before and after the 6 acupuncture treatments were all with statistic significance （all P〈0.05）. Conclusion A certain therapeutic effect can be found in treatment of periarthritis with acupuncture. And the effect at Jianyu （LI 15） is proved to be the most obvious. Jianqian （Extra） and Binao （LI 14） are considered as the second obvious. While no significant effect can be found at Jianliao （TE 14）.
