To check the value of home particle repositioning maneuver in the prevention of the recurrence of posterior canal benign paroxysmal positional vertigo (pc-BPPV).
In this study, patients diagnosed as unilateral posterior canal BPPV were selected following an accurate evaluation using video goggle VNG system. All patients were managed by particle repositioning maneuver (PRM). Patients were instructed to do home PRM once weekly for five years. Then, they were divided into two groups (according to choice of patient to do PRM). The first group (control group) consisted of 144 patients who did not do home PRM; whereas the second group (study group) included 165 patients who performed home PRM. All patients (control & study groups) were followed up every four months for five years.
The study found out that the recurrence rate of pc-BPPV in control group was 33 patients in the first year (27.2%), 11 patients in second year (9%), 5 patients in third year (4%), 3 patients in fourth year (2.5%) and 3 patients in fifth year (2.5%). The recurrence of pc-BPPV in the treated side (study group) of patients was reported as 5 patients in the first year (3.5%), 3 patients in the second year (2%), 2 patients in the third year (1.4%), 2 patients in the fourth year (1.4%), and 1 patient in the fifth year (0.7%). There was statistically significant difference between the control and the study groups regarding the recurrence rates in the first year follow up which was the highest in first four months.
Home particle repositioning maneuver has the capacity to prevent the recurrence of pc-BPPV. It proved to be more successful and functional in minimizing the recurrence of the disease in the study than in the control group. Hence, home particle repositioning maneuver is highly recommended for one year at least in pc-BPPV.
检验家庭颗粒复位法在预防后半规管良性阵发性位置性眩晕（pc-BPPV）复发中的价值。
本研究中，使用视频眼罩式视频眼震图（VNG）系统进行准确评估后，选取诊断为单侧后半规管BPPV的患者。所有患者均接受颗粒复位法（PRM）治疗。指导患者连续五年每周进行一次家庭PRM。然后，根据患者是否选择进行家庭PRM将他们分为两组。第一组（对照组）由144例未进行家庭PRM的患者组成；而第二组（研究组）包括165例进行家庭PRM的患者。所有患者（对照组和研究组）均进行了为期五年的随访，每四个月随访一次。
研究发现，对照组中pc-BPPV的复发率在第一年为33例（27.2%），第二年为11例（9%），第三年为5例（4%），第四年为3例（2.5%），第五年为3例（2.5%）。患者治疗侧（研究组）pc-BPPV的复发情况为第一年5例（3.5%），第二年3例（2%），第三年2例（1.4%），第四年2例（1.4%），第五年1例（0.7%）。在第一年随访时，对照组和研究组的复发率存在统计学显著差异，其中前四个月的复发率最高。
家庭颗粒复位法有预防pc-BPPV复发的能力。在本研究中，它在减少疾病复发方面比对照组更成功且有效。因此，对于pc-BPPV患者，强烈建议至少进行一年的家庭颗粒复位法。
