电阻抗肌电描记术(EIM)量化肌肉健康状况,并用作神经源性和肌病疾病中肌肉异常的生物标志物。肌萎缩侧索硬化症(ALS)患者的舌肌组织中EIM尚未得到评估,ALS患者通常表现出临床延髓体征。对19例运动神经元病患者和21例正常对照者的舌肌进行了EIM、力量和耐力测试及临床观察。与健康组相比,ALS组的舌肌组织的特征在于显著较小的相位(Ph)和较大的阻力(R)。在ALS组中,pH值和舌耐力相关。舌肌组织的EIM可以区分ALS患者和健康对照者。舌功能和Ph之间的关系支持进一步测试舌的EIM作为ALS的潜在生物标志物。
Electrical impedance myography (EIM) quantifies muscle health and is used as a biomarker of muscle abnormalities in neurogenic and myopathic diseases. EIM has yet to be evaluated in the tongue musculature in people with amyotrophic lateral sclerosis (ALS), who often show clinical bulbar signs. The lingual musculature of 19 subjects with motor neuron disease and 21 of normal participants were assessed using EIM, strength and endurance testing, and clinical observation. Tongue musculature in the ALS group was characterized by significantly smaller phase (Ph) and larger resistance (R) when compared to the healthy cohort. Ph and tongue endurance were correlated in the ALS group. EIM of tongue musculature could distinguish people with ALS from healthy controls. The demonstrated relationship between tongue function and Ph supports further testing of EIM of the tongue as a potential biomarker in ALS.
