正常中老年人咽期吞咽功能的表面肌电图研究
Surface Electromyography Studies of Pharyngeal Swallowing in Healthy Middle-aged and Old People
摘要
Abstract
Objective To observe the character of amplitude of myoelectric activity with surface electromyography (sEMG) on pharyn-geal swallowing in healthy middle-aged and elderly people. Methods From January, 2015 to January, 2016, 78 healthy subjects were separat-ed into middle-aged group (38~60 years old, n=38) and elderly group (61~82 years old, n=40). The amplitudes of sEMG activity of related muscles under different swallowing modes were recorded by sEMG technique and analysis system. The root mean square (RMS) was ana-lyzed. Results There was significant difference in RMS among different swallowing modes (F>105.120, P<0.001). There was no difference in RMS between two muscles under all the swallowing modes in both groups (t<1.135, P>0.05). There was no difference between two groups in both muscles under relax and dry swallow (t<1.412, P>0.05), and was different under water swallow and continuous drinking (t>2.700, P<0.05). Conclusion sEMG could be used for analyzing the characteristics of amplitude of myoelectric activity in healthy mid-dle-aged and elderly people during pharyngeal swallowing in different swallowing modes, that can be used to evaluate and screen swallow-ing and dysphagia in clinic.关键词
