Thus, the self-treatment approach is a desirable option for patients with PC-BPPV. PC-BPPV also has a high recurrence rate ( 6, 7) and frequent recurrences render patients with PC-BPPV dependent on costly and time-consuming medical care. In a retrospective study, 84% of patients obtained symptomatic control of PC-BPPV after three Epley maneuvers ( 5), which means repeated Epley maneuvers are required for some patients until PC-BPPV resolves completely. Treatment of PC-BPPV relies on a canalith repositioning maneuver, and the most common approach is the Epley maneuver ( 4).

PC-BPPV is usually diagnosed by the means of the Dix–Hallpike test, which is considered positive when it triggers vertigo symptoms as well as torsional and vertical nystagmus ( 3). Approximately 60-90% of BPPV involves the posterior canal (PC-BPPV) ( 2). It is usually caused by otoconia that are dislodged from the otolith macula beds and become trapped in the semicircular canal ( 1). The modified Epley maneuver group had fewer residual symptoms than that of the Epley maneuver group 1 week after treatment of PC-BPPV ( p 0.05).Ĭonclusions: The modified Epley maneuver has a satisfactory therapeutic efficacy with less residual symptoms and could be recommended as a self-treatment for patients with PC-BPPV.īenign paroxysmal positional vertigo (BPPV) is the common cause of peripheral vertigo. Results: It was found that the modified Epley maneuver group had a higher resolution rate than that of the Epley maneuver group in the treatment of PC-BPPV after 1 day of the initial maneuver ( p 0.05). We analyzed the resolution rate (1 day and 1 week), residual symptoms after the maneuver, and adverse effects. All patients were randomized into the Epley maneuver group ( n = 77) and modified Epley maneuver group ( n = 78). Methods: The study recruited 155 patients with PC-BPPV. Objectives: The purpose of this study is to investigate a modified Epley maneuver for self-treatment of posterior canal benign paroxysmal positional vertigo (PC-BPPV). 3Department of Geriatrics, Xijing Hospital, Fourth Military Medical University, Xi'an, China.2Department of Neurology, Xijing Hospital, Fourth Military Medical University, Xi'an, China.1Department of Neurology, Qionghai People's Hospital, Qionghai, China.Zhuangqin Gan 1 † Shiling Zhou 1 † Hui Yang 1 † Feng He 2 Dong Wei 2 Ya Bai 2 Yuanyuan Wang 2 Yingxia Wang 1 Wei Fu 3 * Junliang Han 2 *
