We evaluated the distribution of muscle weakness in 70 myasthenia gravis (MG) patients, using the MRC scale. Extensors in the upper extremities and proximal flexors in the lower extremities (LE) were found to be weak. Tibialis anterior muscle was rarely affected and only when there was substantial weakness in LE proximal muscles. Attention to this distribution may help in differentiating MG, particularly MG with only limb weakness, from muscular dystrophies.
我们使用医学研究委员会（MRC）量表评估了70例重症肌无力（MG）患者肌无力的分布情况。发现上肢伸肌和下肢近端屈肌无力。胫前肌很少受到影响，只有在下肢近端肌肉明显无力时才会受累。关注这种分布情况可能有助于鉴别重症肌无力，尤其是仅伴有肢体无力的重症肌无力与肌肉萎缩症。
