Monomelic amyotrophy (MMA) is a benign motor neuron disease with bilateral muscular atrophy in asymmetry and abnormal in the electromyography (EMG). However, we report a case by the muscle biopsy which shows symptoms of slowly progressive amyotrophy despite having a normal EMG.
A 51-year-old male was diagnosed with a lower limb amyotrophy, insidious at the onset and located in the distal thigh and the proximal crus near the knee, slowly progressive weakness, and wasting of his right gastrocnemius muscle for the last 20 years.
He was diagnosed with MMA by the clinical profile, natural history, examinations, and the biopsy.
We perform dynamic physical therapy for the patient in this case.
The positive effects of dynamic physical therapy in this case with MMA were shown in this report.
The outcome of physical therapy is satisfactory.
单肢肌萎缩症（MMA）是一种良性运动神经元疾病，表现为双侧不对称性肌肉萎缩，肌电图（EMG）异常。然而，我们报告一例经肌肉活检显示为缓慢进行性肌萎缩症状的病例，尽管其肌电图正常。
一名51岁男性被诊断为下肢肌萎缩症，起病隐匿，位于大腿远端和膝关节附近的小腿近端，在过去20年中逐渐出现右腓肠肌无力和萎缩。
根据临床症状、自然病史、检查及活检结果，他被诊断为MMA。
我们对该病例患者进行了动态物理治疗。
本报告显示了动态物理治疗对该MMA病例的积极效果。
物理治疗的效果令人满意。
