摘要:
      摘要 目的:利用表面肌电图技术研究不同年龄正常人咽期吞咽相关肌群肌电活动的持续时间,建立正常人咽期吞咽肌电活动持续时间的标准数据库。 方法:187例正常受试者,按年龄分为4组:18—30岁组、31—50岁组、51—70岁组、>70岁组。应用表面肌电图技术与分析系统,测量受试者咽期吞咽时相关肌群肌电活动的持续时间,得到不同年龄咽期吞咽时相关肌群肌电活动的持续时间后进行分析。 结果:建立中国正常成人咽期吞咽相关肌群肌电活动持续时间的标准数据库。本数据库显示肌电活动的持续时间与年龄有关,随着年龄的增加呈递增趋势,18—30岁、31—50岁、51—70岁年龄段肌电活动的持续时间无显著性差异(P>0.05),>70岁年龄段肌电活动的持续时间明显延长,且具有显著性差异(P<0.05)。此外,肌电活动的持续时间还与吞咽模式有关,“干”吞咽组和“湿”吞咽组持续时间相差不明显,但都明显低于过量(20ml)吞咽组,且具有显著性差异(P<0.05)。 结论:应用表面肌电技术与分析系统,首次建立中国正常成人咽期吞咽时相关肌群肌电活动持续时间的标准数据库,初步揭示中国正常成人咽期吞咽相关肌群的表面肌电特征,为临床筛查和评估吞咽障碍提供科学参考依据。

Abstract:
      Abstract Objective: To perform surface electromyography (sEMG) studies in Chinese normal adults of different ages to establish normative database of related myoelectric activity duration during pharyngeal swallowing. Method: A total of 187 healthy adults were separated into 4 groups according to their ages: ages 18—30, 31—50, 51—70 and >70 years of age. The duration of related myoelectric activity during pharyngeal swallowing was measured in each subject by sEMG technique and analysis system, then mean value of the duration of related myoelectric activity during pharyngeal swallowing of normal adults of different ages were calculated and analyzed. Result: Normative database for duration and amplitude of myoelectric activity during pharyngeal swallowing was established. The duration of swallows in all tests showed progressively increase with age, but there was no statistically significant difference among Group1, Group2 and Group3(P>0.05), while the duration of myoelectric activity was significantly prolonged in Group4 (P<0.05). In addition, the durations of swallow were related to swallow modes. There was no statistically significant difference for duration of myoelectric activity during “dry” swallow and “wet” swallow in all age groups (P>0.05). But there was significant difference between the duration of “wet” swallow and the duration of excessive (20ml) swallow (P<0.05). Conclusion: This is the first time to establish the reference database of duration of myoelectric activity during pharyngeal swallowing of Chinese normal adults with sEMG technique and analysis system, to reveal the sEMG characteristic of swallowing in Chinese normal adults, provide reference for differential diagnosis between swallowing and dysphagia in clinic.
