The aim of this study was to report some clinical cases suggesting a possible correlation between benign paroxysmal positional vertigo (BPPV) and intense physical activity. Out of 430 BPPV cases referred to our out-patients clinic, 9 patients, showing symptoms of BPPV arising after an intense period of physical activity, were selected for this study. The posterior semicircular canal was affected in all the nine patients. The canalith repositioning procedure was successful and eliminated vertigo and nystagmus in all patients. During the follow-up period (12 months) all patients continued with the usual physical activity; four of the nine patients showed a recurrence of the BPPV symptoms after a new intense period of exercises: all were successfully treated by a new single Epley repositioning procedure. BPPV due to intense physical activity is a rare condition (9/430) and it may be caused by repeated vibratory vertical accelerations of a minor degree associated with metabolic variations during strenuous exercise.
本研究旨在报告一些临床病例，提示良性阵发性位置性眩晕（BPPV）与剧烈体力活动之间可能存在关联。在我们的门诊诊所的 430 例 BPPV 病例中，选择了 9 例在剧烈体力活动后出现 BPPV 症状的患者进行本研究。9 例患者均在后半规管受累。所有患者均成功进行了管石复位程序，消除了眩晕和眼球震颤。在随访期间（12 个月），所有患者继续进行常规体力活动；9 例患者中的 4 例在新的剧烈运动后出现 BPPV 症状复发：所有患者均通过新的单次 Epley 复位程序成功治疗。剧烈体力活动引起的 BPPV 是一种罕见的情况（9/430），可能是由与剧烈运动期间代谢变化相关的、程度较小的反复振动垂直加速引起的。
