A simple, rapid, reproducible method for quantification of lower extremity muscle strength was standardized. The time needed to stand 10 times from a standard chair was recorded in 139 healthy subjects, aged 20 to 85 years (77 men, 62 women). Reproducibility was 6.8 percent (+/- 3.4 percent). Neither height nor weight was related to time in either sex. Weight was related to time (p less than 0.05) after adjusting for age, but this effect was slight compared with the effect of age alone. A highly significant (p less than 0.0001) relationship between time and age was found in both sexes. Younger men performed better than younger women, although this difference was lost in the older age groups. The results of this simple test correlated well with published data on the strength of knee flexor and extensor muscles in groups of men and women of various ages. This method was used to evaluate serially six consecutive patients with classic polymyositis or dermatomyositis. Improvement after treatment with prednisone used alone or in combination with azathioprine or methotrexate was found in all cases.
一种用于量化下肢肌肉力量的简单、快速、可重复的方法被标准化。记录了139名年龄在20至85岁之间的健康受试者（77名男性，62名女性）从标准椅子上站起10次所需的时间。重复性为6.8%（±3.4%）。身高和体重与任何一种性别的时间均无关联。在调整年龄后，体重与时间相关（p<0.05），但与仅年龄的影响相比，这种影响较小。在两性中均发现时间与年龄之间存在高度显著的关系（p<0.0001）。年轻男性的表现优于年轻女性，尽管在老年组中这种差异消失了。这个简单测试的结果与已发表的关于不同年龄组男性和女性膝部屈肌和伸肌力量的数据相关性良好。该方法被用于连续对6例典型多发性肌炎或皮肌炎患者进行系列评估。在所有病例中均发现单独使用泼尼松或与硫唑嘌呤或甲氨蝶呤联合使用治疗后病情有所改善。
