目的研究健康成年人吞咽表面肌电图的特点.方法应用肌电图仪对126例健康成人志愿者吞咽时的表面肌电图进行研究,其中男性66例,女性60例；年龄范围是18～65岁.将记录电极放置于甲状软骨上方1 cm,记录每次吞咽时肌肉电活动的持续时间和振幅.吞咽方式有:空吞咽、吞咽20 ml水、吞咽40 ml水.结果健康成年男性空吞咽、吞咽20 ml水、吞咽40 ml水时肌电活动持续时间平均((x)±s,下同)分别为(1.133±0.209)s、(1.097±0.208)s和(1.510±0.432)s,振幅分别为(0.332±0.115)mV、(0.308±0.095) mV和(0.399±0.139) mV.健康成年女性同样吞咽时肌电活动持续时间分别为(1.118±0.170)s、(1.085±0.209)s和(1.765±0.463)s,振幅分别为(0.292±0.100) mV、(0.261±0.113)mV和(0.342 ±0.129) mV.所有的吞咽方式中男性受试者吞咽时的振幅均大于女性(P值均＜0.05),除吞咽40 ml水的吞咽持续时间女性长于男性(t=3.199,P＜0.05)外,其余吞咽方式的持续时间差异均无统计学意义(P值均＞0.05).所有受试者吞咽40 ml水的时间均长于空吞咽和吞咽20 ml水时,吞咽20 ml水和空吞咽时差异无统计学意义；吞咽40 ml水的振幅大于空吞咽,空吞咽的振幅大于吞咽20 ml水时.不同年龄组男性受试者的肌电图持续时间和振幅差异均无统计学意义(P值均＞0.05)；女性受试者除年轻组(＜30岁)吞咽40 ml水的时间长于年长组外(P＜0.05),其余吞咽方式肌电图参数差异均无统计学意义(P值均＞0.05).结论吞咽的表面肌电图是一种简单、无创的评估吞咽功能的检查方法,本研究取得的健康人群吞咽表面肌电图的数据有望为今后开展吞咽功能筛查提供参考.

Objective To study the characteristics of surface electromyography (sEMG) during swallowing in normal adults.Methods The sEMG during swallowing was carried out in 126 normal adults.There were 66 males and 60 females with their age ranged from 18 to 65 years.The recording electrodes were placed on the skin above the superior thyroid notch and the duration and amplitude of muscle activities during every deglutition were recorded.Swallowing styles were dry swallow,20 ml water swallow and 40 ml water swallow.Results The durations of sEMG at dry swallow,20 ml water swallow and 40 ml water swallow were (1.133 ± 0.209) s ((x) ± s),(1.097 ± 0.208) s,and (1.5 10 ± 0.432) s,while the amplitudes were (0.332±0.115)mV,(0.308 ±0.095)mV,and (0.399 ±0.139)mV in normal male group.The durations of sEMG at dry swallow,20 ml water swallow and 40 ml water swallow were (1.118 ± 0.170)s,(1.085 ± 0.209) s,and (1.765 ± 0.463) s,while the amplitudes were (0.292 ± 0.100) mV,(0.261 ± 0.113)mV,and (0.342 ± 0.129)mV in normal female group.The amplitudes of sEMG in male were higher than those in female (P ＜ 0.05) and the durations had no statistically significant difference between male and female (P ＞ 0.05) in all swallow styles except that the duration of 40 ml water swallow in female was longer than that in male (P ＜ 0.05).In all volunteers,the durations of sEMG at 40 ml water swallow were longer than those at dry swallow and 20 ml water swallow,and there was no statistically significant difference between dry swallow and 20 ml water swallow.The amplitude of sEMG at 40 ml water swallow was higher than that at dry swallow.The amplitude of sEMG in dry swallow was higher than that at 20 ml water swallow.There was no statistically significant difference in durations and amplitudes of sEMG among four different age groups of male.In the female groups,there was no statistically significant difference in durations and amplitudes of sEMG among four different age groups except that the duration at 40 ml water swallow was longer in younger group (＜ 30 years old) than in older groups.Conclusions Surface EMG of swallowing is a simple and noninvasive method for evaluating the swallowing function.The sEMG data of swallowing in normal adults obtained in this study may be used to provide reference for screening swallowing function in adults in the future.
