Despite the high prevalence of the yips, a task-specific movement disorder in athletes, effective exercise therapy remains elusive. This case report aimed to evaluate the impact of task-oriented training on throwing accuracy and kinematic variability in a baseball player with the yips. This study included a 21-year-old baseball player with a 7-year history of the yips. Approximately 50% of the player's typical throws were erratic and uncatchable. However, the frequency of erratic throwing varied depending on the throwing task and its contexts. To address these symptoms, graded task-oriented throwing training was implemented twice a week for 5 weeks. A three-dimensional motion capture system and high-speed camera were employed to assess throwing accuracy and kinematic variability. After the intervention, the frequency of subjective yips symptoms during throwing decreased by approximately one-third. Moreover, the intervention improved the accuracy of the ball arrival position and reduced variability in the ball release angle and shoulder internal rotation angle at ball release. Treating the yips remains challenging owing to concerns regarding doping and side effects. Nonetheless, this study suggests that low-risk physical therapy may have potential clinical utility as a management approach for athletes with the yips.
尽管抽动秽语综合征（运动员中一种特定任务的运动障碍）的患病率很高，但有效的运动疗法仍然难以捉摸。本病例报告旨在评估任务导向训练对一名患有抽动秽语综合征的棒球运动员投球准确性和运动学变异性的影响。本研究纳入了一名有7年抽动秽语综合征病史的21岁棒球运动员。该运动员约50%的典型投球不稳定且无法接住。然而，不稳定投球的频率因投球任务及其背景而异。为解决这些症状，每周进行两次分级任务导向投球训练，共持续5周。采用三维运动捕捉系统和高速摄像机来评估投球准确性和运动学变异性。干预后，投球时主观抽动秽语综合征症状的频率降低了约三分之一。此外，干预提高了球到达位置的准确性，并减少了球出手时出手角度和肩部内旋角度的变异性。由于对兴奋剂和副作用的担忧，治疗抽动秽语综合征仍然具有挑战性。尽管如此，本研究表明，低风险的物理治疗作为一种针对患有抽动秽语综合征的运动员的管理方法可能具有潜在的临床应用价值。
