目的：本研究的目的是基于运动生理学和学习理论原理，开发一种治疗声带运动障碍(PVFMD)运动员的方法，并在预先设定的时间范围内实施。方法：采用前瞻性、重复测量、受试者内分组设计。通过喉镜确诊为PVFMD的11名青少年运动员接受了短期强化(STI)治疗。其中八名运动员返回进行更长时间的随访。比较运动后吸气阻力(R-I)和呼气阻力(R-e)的变化以及基线时收集的改良Borg呼吸困难分级(MBDS)。在基线和长期随访时收集呼吸困难指数评分。两名患有PVFMD的非治疗对照组运动员参加了两项运动挑战-基线和6周后。结果：运动员在STI治疗后立即在R-I、R-E和MBDS评分上有显著改善。这些变化在延长的随访期以及呼吸困难指数评分的显著变化中保持不变。在基线6周后重新评估的2名对照运动员在运动后R-I和MBDS评分方面发生了负变化。结论：结合个体性、特异性和可变练习的STI疗法有效地改变了治疗后的结果指标，并在扩展的随访中观察到进一步的改善。这些结果为STI治疗PVFMD提供了初步证据。
Purpose: The aim of the study was to develop a treatment for athletes with paradoxical vocal fold motion disorder (PVFMD) based on exercise physiology and learning theory principles and administer it over a preestablished time frame.Method: A prospective, repeated-measures, within-subject group design was used. Eleven adolescent/teen athletes diagnosed with PVFMD via laryngoscopy received short-term intensive (STI) therapy. Eight of the athletes returned for extended follow-up. Changes in postexercise inspiratory (R-i) and expiratory (R-e) resistances and Modified Borg Dyspnea Scale (MBDS) ratings collected at baseline were compared immediately posttreatment and at extended follow-up. Dyspnea Index scores were collected at baseline and at extended follow-up. Two no-treatment control athletes with PVFMD participated in two exercise challenges- baseline and 6 weeks later.Results: Immediately after STI therapy, athletes attained significant improvement in R-i, R-e, and MBDS ratings. These changes were maintained at extended follow-up as well as a significant change in Dyspnea Index scores. The 2 control athletes who were reassessed 6 weeks after baseline experienced negative changes in postexercise R-i and MBDS ratings.Conclusion: STI therapy that incorporated individuality, specificity, and variable practice effectively changed outcome measures posttreatment with further improvement observed at extended follow-up. These results provide preliminary evidence for STI therapy for PVFMD.
