表面肌电图在儿童吞咽障碍疾病中的应用

Application of surface electromyography in children with dysphagia

摘要:

目的 探讨表面肌电图在儿童吞咽障碍疾病中的应用价值。方法 选取吞咽障碍患儿20例为观察组，招募性别及年龄相匹配的健康儿童20例为对照组。采用表面肌电图记录两组儿童静息状态及吞水状态颏下肌群和舌骨下肌群肌电积分值。比较两组儿童静息状态下及吞水5 mL后颏下肌群和舌骨下肌群肌电积分值的差异。记录观察组患儿康复治疗1个月后颏下肌群和舌骨下肌群肌电积分值的变化。采用Spearman相关分析法评估观察组患儿吞咽障碍程度与颏下肌群及舌骨下肌群肌电积分值的相关性。结果 静息状态下两组儿童颏下肌群和舌骨下肌群肌电积分差异无统计学意义（P > 0.05），但在吞水后观察组的肌电积分值明显高于对照组（P < 0.05）。治疗后观察组吞咽障碍临床症状改善，颏下肌群和舌骨下肌群肌电积分值较前明显降低（P < 0.05）。吞咽障碍严重程度与颏下肌群和舌骨下肌群肌电积分值呈正相关（P < 0.01）。结论 表面肌电图检查可以作为儿童吞咽障碍诊断及疗效评估的方法之一。

Abstract:

Objective To study the application value of surface electromyography in children with dysphagia. Methods A total of 20 children with dysphagia were enrolled as the observation group, and 20 healthy children, matched for sex and age, were enrolled as the control group. Surface electromyography was used to record the electromyography integral values of the submental and infrahyoid muscle groups in the resting state and the state after water swallowing. The two groups were compared in terms of the electromyography integral values of the submental and infrahyoid muscle groups in the resting state and the state after swallowing 5 mL water. The observation group was observed in terms of the changes in the electromyography integral values of the submental and infrahyoid muscle groups after 1 month of rehabilitation treatment. A Spearman correlation analysis was used to evaluate the correlation of the degree of dysphagia with the electromyography integral values of the submental and infrahyoid muscle groups in the observation group. Results There was no significant difference between the two groups in the electromyography integral values of the submental and infrahyoid muscle groups in the resting state (P > 0.05), while after water swallowing, the observation group had significantly higher electromyography integral values than the control group (P < 0.05). The observation group had significant improvements in the clinical symptoms of dysphagia after treatment, with significant reductions in the electromyography integral values of the submental and infrahyoid muscle groups (P < 0.05). The severity of dysphagia was positively correlated with the electromyography integral values of the submental and infrahyoid muscle groups (P < 0.01). Conclusions Surface electromyography is useful in the diagnosis and therapeutic effect evaluation for dysphagia in children.
