The clinical entity of chronic thyrotoxic myopathy was considered rare by Waldenström in 1945. Forty eight consecutive patients with thyrotoxicosis were studied clinically and by electromyography for muscle involvement. Quantitative electromyographic techniques were used to analyse both the electromyographic activity of the muscle at a standard tension and also the single motor potential obtained in isolation at minimal effort. The interference pattern was described in simple numerical terms such as the number of potential changes/s and the mean amplitude. All cases that were thyrotoxic (both clinically and on thyroid function tests) showed the changes of myopathy on electromyography, though only 68% of the cases showed clinical myopathy consisting of muscle weakness and/or atrophy.
1945年，瓦尔登斯特伦认为慢性甲状腺毒症性肌病这一临床实体较为罕见。对48例连续的甲状腺毒症患者进行了临床及肌电图检查以评估肌肉受累情况。采用定量肌电图技术分析肌肉在标准张力下的肌电活动以及在最小用力时单独获得的单个运动电位。干扰图形用简单的数字术语描述，如每秒电位变化次数和平均波幅。所有临床及甲状腺功能检查均显示甲状腺毒症的病例，其肌电图均呈现肌病改变，尽管只有68%的病例表现出由肌肉无力和/或萎缩组成的临床肌病。
