Manual muscle testing with the examiner providing the resistance has long been a standard test of muscle strength. Through the use of extremities acting as levers, clinicians have been able to effectively apply resistance to all muscle groups except the ankle plantar flexors. As a result, a standing heel-rise test that uses body weight as the resistance has been substituted. The number of heel-rises that represent normal plantar-flexor "strength" and the ability of subjects to repeatedly use that "strength" remain unresolved. Because walking is an endurance task, the hypothesis tested by this study was that individuals without known weakness would be able to perform more than the standard recommended one to five standing heel-rises. The purpose of this study was to measure the number of standing heel-rises that individuals without known weakness could accomplish.
Two hundred three subjects were studied for their ability to do standing heel-rises, as is done when testing plantar-flexion strength using the upright test. There were 122 male subjects and 81 female subjects, ranging in age from 20 to 59 years.
Each subject was asked to do as many standing heel-rises as he or she could, with careful monitoring of body and limb alignment and of ankle motion, with specific criteria for stopping.
The average number of heel-rises was 27.9 (SD = 11.1, minimum = 6, maximum = 70) for all groups and both genders, with no differences between male and female subjects. The lower 99% confidence interval was 25.
A recommendation is made to change the standard of testing plantar-flexion function, when using the standing heel-rise test, to require 25 repetitions for a grade of Normal. [Lunsford BR, Perry J. The standing heel-rise test for ankle plantar flexion: criterion for normal.
由检查者提供阻力的徒手肌力测试长期以来一直是肌力的标准测试方法。通过将四肢用作杠杆，临床医生能够有效地对除踝跖屈肌以外的所有肌肉群施加阻力。因此，已采用以体重为阻力的站立提踵试验来替代。代表正常跖屈“力量”的提踵次数以及受试者反复运用该“力量”的能力仍未得到解决。由于行走是一项耐力任务，本研究检验的假设是，没有已知虚弱情况的个体能够完成超过标准推荐的一到五次站立提踵。本研究的目的是测量没有已知虚弱情况的个体能够完成的站立提踵次数。
对203名受试者进行了站立提踵能力的研究，就像在使用直立试验测试跖屈力量时那样。有122名男性受试者和81名女性受试者，年龄在20至59岁之间。
要求每个受试者尽可能多地进行站立提踵，同时仔细监测身体和肢体的对线情况以及踝关节运动，并制定了停止测试的具体标准。
所有组和男女两性的提踵平均次数为27.9次（标准差 = 11.1，最小值 = 6，最大值 = 70），男性和女性受试者之间没有差异。99%的较低置信区间为25次。
建议在使用站立提踵试验测试跖屈功能时，将正常等级的标准改为要求完成25次重复动作。[伦斯福德BR，佩里J。踝关节跖屈的站立提踵试验：正常标准。
