The degree of physical activity at the onset of spontaneous pneumothorax was evaluated retrospectively in 219 patients, predominantly smokers who had had this disease for the first time. More than 87% had been inactive at the onset of the symptoms. Moderate exertion was recorded in only 2%, and no patients were exerting themselves heavily when the symptoms began. The occurrence of spontaneous pneumothorax was unevenly (p less than 0.001) distributed over the day. In 9% the symptoms had their onset during quick movement--such as fastening a seat belt--without any effort. The inactivity or low activity at the onset of symptoms of spontaneous pneumothorax suggests that this condition is unrelated to muscle effort.
对219例首次患自发性气胸的患者（主要为吸烟者）的发病时体力活动程度进行了回顾性评估。超过87%的患者在症状出现时处于不活动状态。仅2%的患者有中度体力消耗，症状开始时没有患者进行剧烈运动。自发性气胸的发生在一天中分布不均（p<0.001）。9%的患者在快速动作（如系安全带）时毫无费力地出现症状。自发性气胸症状出现时的不活动或低活动状态表明这种情况与肌肉用力无关。
