BACKGROUND: The necessity of postural restriction to patients suffering from benign paroxysmal positional vertigo is controversial.
OBJECTIVE: To investigate the impact of the sleep position after the repositioning maneuver on BPPV recurrence.
METHODS: 150 unilateral BPPV patients who were treated by repositioning maneuver were distributed into two groups. The patients in group A were instructed to sleep in a semi-sitting position at an angle of approximately 30 degrees and refrain from sleeping on their BPPV affected side for one week. The patients in group B were told to sleep in any preferred position. The comparison of recurrence rates according to different actual sleep positions in one week and one month was performed.
RESULTS: There was a statistically significant correlation between the sleeping side and the side affected by BPPV. Without instructions on postural restriction, most patients (82.9%, 73/88) avoided sleeping on their affected side. The patients sleeping on their affected side had a higher recurrence rate (35.3%) than ones sleeping in other positions in the first week after the repositioning maneuver (p<0.05, Chi-square test and Fisher's exact test). The patients sleeping randomly in following 3 weeks had a lower recurrence rate than ones sleeping in other position (p<0.05, Fisher's exact test).
CONCLUSIONS: BPPV patients had a poor compliance to postural instructions. The habitual sleep side was associated with the side affected by BPPV. The patients sleeping on their affected side had a higher recurrence rate than those sleeping in other positions in first week after the repositioning maneuver.
