[Analysis of electromyographic findings in 37 cases of thyrotoxicosis].
The EMG findings of 100 skeletal muscles in 37 cases of thyrotoxicosis are reported. The abnormal short duration motor unit potentials occurred in 78% of examined muscles and in 45% of these muscles, the incidence of polyphasic potentials increased. These abnormalities were in agreement with myopathic lesion exactly. EMG examination is a secure and sensitive method to find impaired muscles. The wide effects of large amount of thyroxin on muscle's metabolism may result in myopathic abnormalities of EMG.
