Effects of Different Durations and Frequencies of Vestibular Rehabilitation in Patients With Residual Symptoms After Benign Paroxysmal Positional Vertigo Repositioning.

This study investigated the effects of varying duration and daily frequency of vestibular rehabilitation (VR) on residual symptoms in patients after successful repositioning for benign paroxysmal positional vertigo (BPPV). In a cohort of 118 patients, groups receiving VR for 4 weeks with different session lengths and frequencies showed significant improvements in dizziness handicap inventory (DHI) and vestibular rehabilitation benefit questionnaire (VRBQ) scores compared to a control group without VR. Emotional symptoms improved notably after 2 weeks of VR, while longer total VR duration correlated with greater reductions in dizziness and disability; however, increasing session length or daily frequency beyond 15 minutes and three times per day did not significantly enhance overall outcomes, except for earlier relief of motion-provoked dizziness. The findings support recommending at least 4 weeks of VR to alleviate residual dizziness and improve quality of life in elderly patients post-BPPV repositioning, with adjustments in VR duration tailored to patient tolerance and emotional status.
