背景和目的。部分负重（PWB）是物理治疗师通常教授的一项技能。本研究比较了练习与任务期间提供的增强反馈（并发反馈）或任务后提供的增强反馈（反应后反馈）对拄着拐杖学习 PWB 的效果。科目。六十名没有已知神经肌肉骨骼系统损伤的年轻人自愿参加了这项研究。方法。受试者练习在踏上地秤时支撑 30% 的体重。在并发反馈组的每次试验期间以及在每次试验之后或在反应后反馈组的每五次试验之后提供增强反馈。两天后，受试者返回进行无反馈保留测试。结果。在练习过程中，并发反馈组比任何一个响应后反馈组都更加准确和一致。然而，在保留期间，反应后反馈组是最准确的。所有组在保留期间都同样一致。结论与讨论。这些结果表明，同时反馈的练习有利于即时表现，但无利于学习这种感觉运动技能。
Background and Purpose. Partial weight bearing (PWB) is a skill commonly taught by physical therapists. This study compared the effects of practice with either augmented feedback provided during the task (concurrent feedback) or augmented feedback provided after the task (postresponse feedback) for the learning of PWB with crutches. Subjects. Sixty young adults without known impairment of the neuromusculoskeletal system volunteered for the study. Methods. Subjects practiced supporting 30% of body weight while stepping onto a floor scale. Augmented feedback was provided during each trial for the concurrent feedback group and either following each trial or after every five trials for the postresponse feedback groups. Subjects returned 2 days later for a no-feedback retention test. Results. During practice, the concurrent feedback group was more accurate and consistent than either of the postresponse feedback groups. During retention, however, the postresponse feedback groups were the most accurate; all groups were equally consistent during retention. Conclusion and Discussion. These results suggest that practice with concurrent feedback is beneficial for the immediate performance but not for the learning of this sensorimotor skill.
