To determine whether learning curves can be observed with deliberate practice when the goal is to apply a consistent rate of force at 5 N/second during pressure pain threshold (PPT) testing in healthy volunteers. In this prospective study, 17 clinician participants completed PPT targeted rate-of-application testing with healthy volunteers using three different feedback paradigms. The resultant performances of ramp rate during 36 trials were plotted on a graph and examined to determine whether learning curves were observed. Clinicians were not consistent in the rate of force applied. None demonstrated a learning curve over the course of 36 trials and three testing paradigms. The results of this study indicate that applying a consistent 5 N/second of force is difficult for practising clinicians. The lack of learning curves observed suggests that educational strategies for clinicians using PPT may need to change.
为了确定在健康志愿者进行压力疼痛阈值（PPT）测试时，以5牛/秒的恒定速率施加力为目标的情况下，刻意练习是否能观察到学习曲线。在这项前瞻性研究中，17名临床医生参与者使用三种不同的反馈范式，对健康志愿者进行了PPT目标施加速率测试。在36次试验中得出的斜坡速率表现被绘制在图表上，并进行检查以确定是否观察到学习曲线。临床医生在施加力的速率上并不一致。在36次试验和三种测试范式过程中，没有人表现出学习曲线。这项研究的结果表明，对于执业临床医生来说，以5牛/秒的恒定速率施加力是困难的。观察到缺乏学习曲线表明，针对临床医生使用PPT的教育策略可能需要改变。
