OBJECTIVES/HYPOTHESES: This study aimed to describe the demographic characteristics of patients diagnosed with paradoxical vocal fold motion (PVFM) at Walter Reed Army Medical Center (WRAMC), and to document common medical comorbidities. The military population was expected to differ from the general population because of a presumed association between high physical demands and PVFM. STUDY DESIGN: Retrospective chart review of active-duty (AD) military personnel compared with a natural control group of non-AD patients. METHODS: Reports of asthma, allergy, gastroesophageal reflux disease (GERD), and postnasal drip (consequent to chronic sinusitis) were recorded for patients referred to the Speech Pathology Clinic at WRAMC with a diagnosis of PVFM from 1996 to 2001. RESULTS: The cohort consisted of 265 patients, 127 of whom were on AD status. The AD group was significantly younger and represented a narrower age range (17-53 years) than the non-AD patients (8-80 years), and had a more balanced sex ratio (1.2:1 vs 2.9:1). Eighty percent of all patients had at least one of the medical comorbidities surveyed, and 51% had two or more factors. GERD and allergies were reported most commonly by both groups; only asthma occurred significantly more in non-AD than AD patients. CONCLUSIONS: PVFM referrals of AD personnel of the US military are characterized by younger patients and a smaller female:male ratio as compared with non-AD patients. Based on the preponderance of men in the military, the number of females in the AD group remained disproportionately large. Multiple medical comorbidities were commonly documented by both groups; the only significant difference was a greater prevalence of asthma in the non-AD group. These data reinforce the need for appropriate differential diagnosis in all patients.

机译：目的/假设：本研究旨在描述在沃尔特·里德陆军医疗中心（WRAMC）被诊断出患有悖论性声带运动（PVFM）的患者的人口统计学特征，并记录常见的合并症。由于高物理需求和PVFM之间的推测联系，预计军事人口有别于一般人口。研究设计：现役（AD）军事人员与非AD患者的自然对照组的回顾性图表回顾。方法：1996年至2001年间，WRAMC的言语病理学诊所诊断为PVFM的患者记录了哮喘，过敏，胃食管反流病（GERD）和鼻后滴注（由于慢性鼻窦炎）的报告。包括265位患者，其中127位处于AD状态。 AD组比非AD组（8-80岁）年轻得多，年龄范围更窄（17-53岁），性别比例更平衡（1.2：1 vs 2.9：1）。所有患者中有80％患有至少一种所调查的医学合并症，而51％的患者患有两种或多种因素。两组都最常报告GERD和过敏。在非AD患者中，仅哮喘发生率明显高于AD患者。结论：与非AD患者相比，美军AD人员PVFM转诊的特点是患者年轻，女性与男性的比例较小。基于军队中男性的占多数，AD组中的女性人数仍然过高。两组通常都记录有多种合并症。唯一的显着差异是非AD组的哮喘患病率更高。这些数据加强了对所有患者进行适当的鉴别诊断的需要。
