[Purpose] Although it is widely recognized that feedback is important for skill acquisition or improvement, feedback is not completely utilized in physical therapy education. Therefore, we aimed to verify the effect of extrinsic feedback from a feedback device on proficiency in range of motion measurements by a universal goniometer. [Participants and Methods] The participants included 22 physical therapy students who were randomly assigned to feedback (n=11) and non-feedback groups (n=11). The passive right knee flexion range of motion was set as the measurement task. The experiment consisted of a pretest phase, practice trials, and a posttest phase. In the pretest phase, all participants conducted three measurements without extrinsic feedback. Extrinsic feedback related to measurement error from a device was given only to the feedback group. The posttest was conducted 24 hours after the practice trials with the same content as that in the pretest. [Results] The improvement rate from pretest to posttest was greater in the feedback group than in the non-feedback group. The results indicated that the measurement error decreases with extrinsic measurement error-related feedback during practice. [Conclusion] The utilization of extrinsic feedback from a feedback device is effective for enhancing range of motion measurement skills.
[目的] 尽管人们普遍认识到反馈对于技能习得或提高很重要，但在物理治疗教育中反馈并未得到充分利用。因此，我们旨在验证反馈设备提供的外部反馈对使用通用角度计进行运动范围测量的熟练程度的影响。[参与者与方法] 参与者包括22名物理治疗专业学生，他们被随机分为反馈组（n = 11）和无反馈组（n = 11）。将右膝被动屈曲运动范围设定为测量任务。实验包括预测试阶段、练习试验和后测试阶段。在预测试阶段，所有参与者在没有外部反馈的情况下进行三次测量。仅向反馈组提供与设备测量误差相关的外部反馈。练习试验24小时后进行后测试，其内容与预测试相同。[结果] 反馈组从预测试到后测试的改善率高于无反馈组。结果表明，在练习过程中，与外部测量误差相关的反馈会使测量误差减小。[结论] 利用反馈设备提供的外部反馈对提高运动范围测量技能有效。
