Abstract

Objective

Exercise-induced laryngeal obstruction (EILO) is a common cause of breathing difficulties during physical exercise. This study examined the relationship between EILO diagnosis and factors influencing laryngeal function in the cohort of Polish athletes.

Material and Methods

We retrospectively analyzed data from 31 patients diagnosed with exertional dyspnea at the National Centre for Sports Medicine over a 2.5-year period. The analysis included results from spirometry, flexible videolaryngoscopy at rest, continuous laryngoscopy during exercise (CLE), assessment of laryngeal reflux using the reflux symptom index (RSI) and reflux finding score (RFS) scales, and palpation of neck muscle tension performed by an otolaryngologist.

Results

Out of the 31 athletes, 14 (45%) were diagnosed with EILO, 9 (29%) with asthma, and 1(7%) had both EILO and asthma. In 7 athletes, no specific respiratory conditions were diagnosed. While self-reported reflux symptoms (RSI) were similar between groups, RFS scores reflecting visible laryngeal changes were significantly higher in the non-EILO group (4.53 vs. 1.43). Neck muscle tension levels were similar across both groups.

Conclusion

The incidence of EILO among Polish athletes diagnosed with exertional dyspnea is consistent with findings in other countries. While laryngopharyngeal reflux disease is not directly correlated with EILO, patients with EILO may report relatively high scores on self-assessment reflux scales due to the similarity of symptoms. Furthermore, neck muscle tension levels were not correlated with EILO in our patient cohort.

波兰运动员人群中运动性喉部梗阻（EILO）和改变喉部功能的因素

目的：运动性喉部梗阻（EILO）是体育锻炼中引起呼吸困难的常见原因。本研究探讨波兰运动员EILO诊断与喉功能影响因素的关系。材料和方法我们回顾性分析了在国家运动医学中心诊断为运动性呼吸困难的31例患者2.5年的资料。分析包括肺活量测定法、静息时柔性视频喉镜检查、运动时连续喉镜检查（CLE）、使用反流症状指数（RSI）和反流发现评分（RFS）量表评估喉反流的结果，以及耳鼻喉科医生进行的颈部肌肉紧张触诊。结果31例运动员中，EILO 14例（45%），哮喘9例（29%），EILO合并哮喘1例（7%）。在7名运动员中，没有诊断出特殊的呼吸系统疾病。虽然两组之间自我报告的反流症状（RSI）相似，但非eilo组反映可见喉部变化的RFS评分明显更高（4.53比1.43）。两组的颈部肌肉紧张程度相似。结论波兰运动性呼吸困难运动员EILO的发生率与其他国家的调查结果一致。虽然咽喉反流病与EILO没有直接关系，但由于症状相似，EILO患者在自我评估反流量表上的得分可能相对较高。此外，在我们的患者队列中，颈部肌肉张力水平与EILO无关。
