【摘要】：目的利用表面肌电(sEMG)技术观察无症状腔隙性脑梗死(LI)患者咽期吞咽相关肌群在不同吞咽模式下肌电活动的特点。方法 2015年1月至2017年1月,连续性收集临床诊断为LI且无吞咽障碍主诉老年患者(LI组)32例以及性别年龄匹配的正常老年人(正常组)30例。应用表面肌电技术与分析系统,记录受试者不同吞咽模式下舌骨下肌群、颏下肌群肌电活动振幅的均方根(RMS)。结果两组组内舌骨下肌群、颏下肌群RMS在不同模式下均存在非常高度显著性差异(F110.67,P0.001)。放松模式和干吞咽模式下,两组间舌骨下肌群、颏下肌群RMS均无显著性差异(t1.484,P0.05)。20 ml含水吞咽模式下,LI组颏下肌群RMS明显低于正常组(t=3.334,P0.01),舌骨下肌群RMS有降低趋势,但无显著性差异(t=1.871,P0.05)。100 ml连续饮水模式下,LI组舌骨下肌群、颏下肌群RMS均明显低于正常组(t3.118,P0.01)。结论无症状LI患者吞咽功能较正常同龄人减退;sEMG技术可用于对其吞咽功能进行评估。
[Abstract]:Objective to observe the characteristics of myoelectric activity in patients with asymptomatic lacunar infarction (Li) by surface electromyography (SEMG) under different swallowing modes. Methods from January 2015 to January 2017, 32 patients with Li and 30 normal subjects (normal group) with Li and no dysphagia were collected from January 2015 to January 2017. Surface electromyography and analysis system were used to record the mean square root mean square (RMS) amplitude of myoelectric activity of subhyoid and submental muscles in different swallowing modes. Results the RMS of subhyoid and submental muscles in the two groups were significantly different in different modes (F110.67, P0.001). In relaxation mode and dry swallowing mode, there was no significant difference between the two groups in subhyoid muscle group and submental muscle group RMS. The RMS of submental muscle group in Li group was significantly lower than that in normal group under water swallowing mode. The RMS of hypohyoid muscle group decreased. However, there was no significant difference in the RMS of subhyoid and submental muscles in the Li group under the continuous drinking water model of 1.871g / 100ml, which was significantly lower than that in the normal group (P < 0.01). Conclusion the sEMG technique can be used to evaluate the swallowing function of asymptomatic Li patients.
