目的本研究的目的是探讨六周旋转神经肌肉控制训练（POINT）中腿部旋转神经肌肉控制的学习模式，并估计在开始时需要多少次训练来估计整体旋转神经肌肉控制的学习曲线。方法20名受试者（男10女10）使用离轴椭圆训练机进行18次POINT训练（每周3次，持续6周）。当受试者被要求在滑滑的条件下控制旋转运动时，在每次学习过程中，包括旋转不稳定性和步速在内的表现指标被量化。通过幂律和指数曲线将旋转不稳定性与训练时间相关的学习曲线量化为训练时间或天数的函数，其中包含三个参数：学习极限、学习速度和学习能力。结果幂次学习模型和指数学习模型的学习曲线特征相似，R2无差异。在学习极限、学习速度和学习能力方面没有发现显著的性别差异。基于r2和RMSE，前三个学习阶段的数据可能足以估计整个训练期间神经肌肉的旋转表现。结论运动技能对旋转不稳定性的改善遵循学习曲线模型。研究结果和模型可用于制定更有效的特定主题治疗计划。
ObjectiveThe goal of this study was to investigate the learning patterns in leg pivoting neuromuscular control performance over six-week pivoting neuromuscular control training (POINT) and to estimate how many sessions at beginning are needed to estimate the overall pivoting neuromuscular control learning curve.MethodsTwenty subjects (ten females, ten males) participated in 18 sessions of POINT (three sessions per week for six weeks) program using an off-axis elliptical trainer. Performance measures including pivoting instability and stepping speed were quantified for each study session during a stepping task while subjects were asked to control pivoting movements under a slippery condition. Learning curve relating the pivoting instability to training sessions was quantified by the power law and by the exponential curve as a function of sessions or days with three parameters: The limit of learning, rate of learning, and learning capacity.ResultsThe power and exponential learning models characterized the learning curves similarly with no differences in R2. No significant sex differences were found in the limit of learning, rate of learning, and learning capacity. Based on R2and RMSE, data from the first three study sessions might be enough to estimate the pivoting neuromuscular performance over the whole training period.ConclusionThe findings showed that subjects' motor skills to improve pivoting instability followed the learning curve models.SignificanceThe findings and models can potentially be used to develop more effective subject-specific therapy scheduling.
