摘要
目的:探讨采用新型的MyotonPro肌张力检测仪定量检测正常人口面部肌肉肌张力和粘弹性的可行性,并分析年龄对其的影响。方法:选取正常人年龄分为20—40岁10例、40—60岁8例、60岁以上8例,以及1例肌萎缩侧索硬化症患者,采用MyotonPro检测双侧咬肌、上下唇以及舌的振动频率(frequency,F)、硬度(stiffness,S)、衰减系数(decrement,D)、博德系数(creep,C)和松弛时间(relaxation,R),1周后进行重测信度检测。结果:咬肌、上下唇及舌的F和S不同年龄段的差异均有显著性意义(P<0.05),且年龄较大(>60岁)的受试者均大于年龄较小者(P<0.05)。仅上下唇及舌的C和R三组间的差异有显著性意义(P<0.05),且60岁以上受试者的C和R均较40岁以下的降低(P<0.05)。而所有检测部位的D三组间差异均无显著性意义(P>0.05)。F和S的重测信度均高(ICC>0.8),C和R的重测信度中等(ICC=0.6—0.72),D信度最低(ICC=0.34)。肌萎缩侧索硬化症患者的咬肌及唇的F和S均较同龄正常人升高,而舌肌的F和S均较同龄正常人降低。结论:MyotonPro能用于检测口面部肌肉的肌张力和粘弹性,其中频率和硬度指标信度较高,但均受年龄因素影响,可能成为诊断神经源性疾病患者口面部肌肉异常的指标之一。
Objective： To assess the stiffness and muscle tone of oromotor muscle using MyotonPro in healthy people across ages. Method： MyotonPro was used to measure the frequency, stiffness, decrement, creep and relaxation of bilateral masseters, tongue and upper and lower lip in 26 healthy adults, including three groups, 10 in 20---40 years group, 8 in 4040 years group, and 8 in above 60 years group, and one patient With ALS. Test-retest reliabil- ity was conducted after one week in 6 healthy adults. Result： The frequency and stiffness of the masseter, lip and tongue differed across ages （P〈0.05）, while the creep and relaxation differed only in lip and tongue in three groups . The older subjects （〉60 years） had great- er frequency and stiffness as well as lower creep and relaxation than the younger ones. By contrast, the differ- ence of decrement across groups were not significant. Retest results showed that the frequency and stiffness measures had highest reliability. The increase of frequency and stiffness and decrease of creep and relaxation were found in the ALS patient compared to the healthy adults in the same age group. Conclusion： MyotonPro may be a tool to assess the muscle tone and stiffness in orofacial muscle. Among the measurements, the frequency and stiffness had highest reliability and age-related effect, which can be developed as a tool for diagnosis of oromotor muscle tone in neurological diseases.
