目的：采用手持式肌力计对健康受试者进行上肢和下肢17个肌群的力量测试，并检验测试方案的插入和间歇可靠性。对象和器械：使用Penny&Giles手持式肌力计对20~69岁(n=200)的20名男性和20名女性进行测试。结果：除踝关节背屈肌外，插位和节间可靠性的信度系数均为.85。在所有肌肉群中，男性比女性施加的力量要大得多。在大多数肌肉群中，年龄、体重和测试侧是力量的重要预测因子。第五百分位值作为正常的下限，每十年分别报告性别和测试侧。结论：使用本研究指定的测试方案，可以将各种神经肌肉疾病患者的数据与适当的性别和年龄匹配的正常数据进行比较，以准确地识别虚弱的存在。
Objective: To measure the strength of 17 muscle groups in the upper and lower extremities in a large group of healthy subjects using "break" testing with a hand-held myometer, and to examine the intrasession and intersession reliability of the testing protocol.Subjects and Instrumentation: A convenience sample of 20 men and 20 women in each decade of age from 20 to 69 years (n = 200) was tested using a Penny & Giles hand-held myometer.Results: Reliability coefficients were >.85 for both intrasession and intersession reliability, except for the ankle dorsiflexors. Men exerted a significantly greater force than women for all muscle groups. Age, weight, and side of testing were significant predictors of force in the majority of muscle groups. The fifth percentile values, as the lower limit of normal, are reported separately for gender and side of testing for each decade of age.Conclusion: Using the testing protocol specified in this study, data from patients with various neuromuscular diseases may be compared with the appropriate gender- and age-matched normal data to accurately identify the presence of weakness.
