【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(P0.05),且年龄较大(60岁)的受试者均大于年龄较小者(P0.05)。仅上下唇及舌的C和R三组间的差异有显著性意义(P0.05),且60岁以上受试者的C和R均较40岁以下的降低(P0.05)。而所有检测部位的D三组间差异均无显著性意义(P0.05)。F和S的重测信度均高(ICC0.8),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。
[Abstract]:Objective: to investigate the feasibility of quantitative detection of facial muscle tension and viscoelasticity by a new type of MyotonPro muscle tension detector and to analyze the influence of age on it. Methods: normal subjects were divided into 10 patients aged 20-40 years, 8 patients aged 40 to 60 years, 8 patients over 60 years old, and 1 patient with amyotrophic lateral sclerosis. Bilateral masseter muscles were detected by MyotonPro. The vibration frequency (frequency,F), hardness (stiffness,S), attenuation coefficient (decrement,D), Bode coefficient (creep,C) and relaxation time (relaxation,R) of the upper and lower lip and tongue were measured after one week. Results: the F and S of masseter muscle, upper lip and tongue were significantly different (P0.05), and the subjects with older age (60 years old) were larger than those with younger age (P0.05). There was significant difference between C and R of upper and lower lip and tongue (P0.05), and C and R of subjects over 60 years old were lower than those of under 40 years old (P0.05). However, there was no significant difference among the three groups (P0.05). F and S had high retest reliability (ICC0.8), moderate retest reliability (ICC=0.6-0.72) and low D reliability (ICC=0.34) of C and R. The F and S of masseter muscle and lip of patients with amyotrophic lateral sclerosis were higher than those of normal subjects of the same age, but F and S of tongue muscle were lower than those of normal subjects of the same age. Conclusion: MyotonPro can be used to detect the muscle tension and viscoelasticity of facial muscles. The reliability of frequency and hardness index is higher, but both of them are affected by age factors, which may be one of the indicators for diagnosing the abnormality of facial muscles in patients with neurogenic diseases.
