Isometric strength of different muscle groups was recorded in thiryty-nine patients suffering various acute infectious diseases, predominantly of viral or mycoplasma aetiology. Recordings were performed after subsidence of fever, and 1, and 4 months thereafter. A control group of twenty-two healthy men, confined to bed for the same period of time as the patients, were investigated at the same time intervals. In addition, control measurements were performed after 1 year in the patients, prior to bed rest in the control subjects. As a result of illness muscle strength was decreased significantly to 85.4-95.3% of that recorded at 4 months. In the control subjects strength did not change significantly, the corresponding percentages being 96.3-102.5. Thus, the present data indicate that these illnesses in themselves may bring about isometric muscle strength reduction.
对39例患有各种急性传染病（主要是病毒或支原体病因）的患者记录了不同肌肉群的等长肌力。在退热后、此后1个月和4个月时进行记录。同时对22名健康男性组成的对照组进行了调查，这些健康男性卧床时间与患者相同，且在相同的时间间隔进行检查。此外，对患者在患病1年后、对对照组在卧床休息前进行了对照测量。患病导致肌肉力量显著下降至4个月时记录值的85.4% - 95.3%。对照组的力量没有显著变化，相应百分比为96.3% - 102.5%。因此，目前的数据表明这些疾病本身可能导致等长肌肉力量下降。
