摘要
背景:改良食物稠度和容积是临床常用的吞咽代偿方法,空吞咽是常用的评估方法,舌骨肌群是吞咽的重要肌群,空吞咽与不同容积和稠度吞咽任务对舌骨肌群的激活水平产生的影响目前尚不明确。目的:探讨一次空吞咽与不同稠度和容积吞咽任务对健康成人舌骨肌群的影响。方法:2019年4-8月从山东体育学院招募44名健康成人,男19名,女25名,平均年龄(21.7±2.8)岁,每名受试者分别执行空吞咽与不同稠度[国际吞咽障碍食物标准(IDDSI)框架0-4级]和容积(5,10,20 mL)吞咽任务,实时记录执行每次吞咽任务时舌骨肌群的表面肌电信号。对原始肌电信号进行处理后,分析对比空吞咽与执行不同稠度和容积吞咽任务时舌骨肌群激活水平的差异。结果与结论:①0-4级20 mL、3级10 mL和4级5 mL吞咽任务对应的舌骨上肌群平均振幅值高于空吞咽(P<0.05);除3级外,20 mL不同稠度吞咽任务对应的舌骨上肌群平均振幅值均高于5 mL相应稠度吞咽任务(P<0.05);除2,3级外,20 mL不同稠度吞咽任务对应的舌骨上肌群平均振幅值均高于10 mL相应稠度吞咽任务(P<0.05);②所有吞咽任务所对应的舌骨下肌群平均振幅值均高于空吞咽(P<0.05);20 mL不同稠度吞咽任务对应的舌骨下肌群平均振幅值高于5,10 mL相应稠度吞咽任务(P<0.05);除3级外,10 mL不同稠度吞咽任务对应的舌骨下肌群平均振幅值均高于5 mL相应稠度吞咽任务(P<0.05);③结果提示,健康成人在执行不同容积和稠度吞咽任务时,舌骨肌群的激活水平不易受IDDSI 0-4级稠度的影响,易受容积的影响,容积越大舌骨肌群的激活水平越高。
BACKGROUND:Modification of food consistency and volume is a commonly used method of swallowing compensation in clinical practice.Dry swallowing is a commonly used method of evaluation.The hyoid muscles are very important in swallowing.The effects of dry swallowing and swallowing tasks of different consistencies and volumes on hyoid muscle activation levels are still unclear.OBJECTIVE:To explore the effects of simple dry swallowing and swallowing tasks of different consistencies and volumes on the hyoid muscles in healthy adults.METHODS:A total of 44 healthy adults were included from April to August 2019,including 19 males and 25 females,with an average age of(21.7±2.8)years.They randomly performed dry swallowing and swallowing tasks of different consistencies(the International Dysphagia Diet Standardisation Initiative(IDDSI)frame levels 0-4)and volumes(5,10,20 mL),and the surface electromyogram signals of the hyoid muscles during each swallowing task were recorded.After processing the raw surface electromyogram signals,the activation levels of the hyoid muscles were compared between dry swallowing and swallowing tasks of different consistency and volume.RESULTS AND CONCLUSION:The mean amplitude values of the suprahyoid muscles corresponding to swallowing tasks of 20 mL for levels 0-4,10 mL for level 3,and 5 mL for level 4 were higher than those of dry swallowing(P<0.05).The mean amplitude values of the suprahyoid muscles corresponding to the 20-mL swallowing tasks of different consistencies were higher than those of the 5-mL swallowing tasks of the corresponding consistencies,except for level 3(P<0.05).The mean amplitude values of the suprahyoid muscles corresponding to the 20-mL swallowing tasks of different consistencies were higher than those of the 10-mL swallowing tasks of the corresponding consistencies,except for levels 2 and 3(P<0.05).The mean amplitude values of the infrahyoid muscles corresponding to all swallowing tasks were higher than that of dry swallowing(P<0.05).The mean amplitude values of the i
