The muscle strength of the quadriceps muscle was measured in a computerized modified Cybex II muscle dynamometer. The method used is easy and has an error of greater than 5%. A marked increase in muscular strength was found after successful surgery for primary hyperparathyroidism (PHPT) with normalization of serum calcium levels. The results support the opinion that all patients with PHPT, with or without muscle weakness, should be recommended an operation if no serious contra-indications exist.
使用计算机化改良的Cybex II肌肉测力计测量股四头肌的肌力。所采用的方法简便，但误差大于5%。在原发性甲状旁腺功能亢进症（PHPT）成功手术后，随着血清钙水平恢复正常，发现肌肉力量显著增加。这些结果支持这样一种观点，即所有PHPT患者，无论有无肌无力，如果不存在严重禁忌证，均应建议进行手术。
