Muscle strength in neuropathic patients is usually evaluated clinically using manual muscle testing (MMT). Detection and grading of mild symmetrical muscle weakness using MMT is difficult partly because the examiner must take into consideration the normal variation in strength in relation to age, weight, height, and gender. In the present study assessment of the strength of ankle dorsal and plantar flexors and knee flexors and extensors with MMT and isokinetic dynamometry were compared in 108 patients, of whom 86 had diabetes mellitus and 22 had alcoholic liver cirrhosis. The isokinetic muscle strength of the patients was compared with the strength of 90 healthy control subjects, adjusted for the influence of age, weight, and height for both genders. MMT resulted in a significant underestimation of the frequency and severity of muscle weakness in both the ankle and the knee. In 28-41% of the comparisons, MMT misclassified the strength performance with one category or more (> 25%). Misclassifications were most frequent for the ankle plantar flexors.
神经性疾病患者的肌肉力量通常通过临床手法肌力测试（MMT）进行评估。使用MMT检测和分级轻度对称性肌肉无力存在困难，部分原因在于检查者必须考虑到与年龄、体重、身高和性别相关的正常力量变化。在本研究中，对108例患者的踝关节背屈肌和跖屈肌以及膝关节屈肌和伸肌进行了MMT评估，并与等速肌力测试进行了比较，其中86例患有糖尿病，22例患有酒精性肝硬化。将患者的等速肌力与90名健康对照者的力量进行比较，并针对年龄、体重和身高对男女的影响进行了调整。MMT导致对踝关节和膝关节肌肉无力的频率和严重程度的显著低估。在28%-41%的比较中，MMT将力量表现误分类为一个或多个类别（>25%）。踝关节跖屈肌的误分类最为频繁。
