目的：我们调查了年轻的哮喘患者是否有平衡障碍，以及这种障碍是否与肌肉骨骼功能和/或心理特征的改变有关。研究方法：21名参与者自我报告哮喘诊断，但没有已知的姿势不稳定或福尔斯史，18名对照参与者从本科心理学课程招募。参与者进行姿势控制任务，即在有视觉反馈（反馈条件）的情况下将压力中心（COP）保持在固定位置，并在没有视觉反馈的情况下尽可能保持静止（无反馈条件）。COP的变异性，规律性和任务性能被用来表征平衡的质量。为了记录肌肉骨骼功能的组间差异，我们测量了颈部和下背部角度以及颈部在额状面和矢状面的运动范围（ROM）。为了记录心理状态的群体差异，我们进行了自我报告问卷调查，以评估焦虑和抑郁症状，焦虑敏感性和负面影响。结果如下：两组之间COP变异性和任务表现相似，但哮喘参与者表现出更规律的前后COP动力学。哮喘患者的颈部伸展活动度较小，颈部更向前弯曲，胸椎角度更大，并且他们报告了更高水平的焦虑敏感性方面的身体问题。这些肌肉骨骼和情感变量调节组间COP差异。结论：在没有任何明显平衡障碍的情况下，年轻成人哮喘患者表现出不同的姿势控制策略。这种策略的改变与哮喘患者的肌肉骨骼和情感特征有关。
Objective: We investigated whether young adults with asthma have impaired balance and whether this impairment is related to altered musculoskeletal function and/or psychological characteristics. Methods: 21 participants with a self-reported asthma diagnosis but no known postural instability or history of falls, and 18 control participants were recruited from undergraduate psychology courses. Participants performed a postural control task of maintaining the center of pressure (COP) in a fixed position with visual feedback (feedback condition) and while standing as still as possible without visual feedback (no-feedback condition). COP variability, regularity and task performance were used to characterize the quality of balance. To document group differences in musculoskeletal function, we measured neck and lower back angles as well as range of motion (ROM) of the neck in the frontal and sagittal planes. To document group differences in psychological state, we administered self-report questionnaires to assess symptoms of anxiety and depression, anxiety sensitivity and negative effect. Results: COP variability and task performance were similar between the groups, but participants with asthma exhibited more regular anterior-posterior COP dynamics. Participants with asthma had smaller ROM of neck extension, a more forwardly bent neck, greater thoracic spine angle, and they reported greater levels of the physical concerns facet of anxiety sensitivity. These musculoskeletal and affective variables moderated COP differences between the groups. Conclusions: Young adults with asthma showed a different postural control strategy in the absence of any obvious balance impairment. This change in strategy is related to musculoskeletal and affective characteristics of individuals with asthma.
