To evaluate the efficacy of vestibular rehabilitation therapy (VRT) on patients with chronic dizziness, and to provide a clinical evidence for the application of VRT in chronic dizziness rehabilitation.

Sixty patients with chronic dizziness were randomly divided into experimental group (n=30) and control group (n=30). The control group was treated with betahistine mesylate tablet and Xuanyunning tablet, while the experimental group received vestibular rehabilitation therapy on the basis of the control group. The assessment measures included the visual analogue scale of dizziness, the dizziness handicap inventory (DHI), the activities-specific balance confidence scale (ABC), the modified Barthel index (MBI), the hospital anxiety and depression scale (HADS) and the Pittsburgh sleep quality index (PSQI). Patients were evaluated before treatment, after 4 weeks of treatment, and at 3 months of follow-up.

Before treatment, there was no significant difference in general information and dizziness related evaluation indexes between the two groups (P>0.05). After 4 weeks of treatment and at the 3-month follow-up, the experimental group showed significantly lower Visual analogue scale of dizziness, DHI score and HADS score (P<0.05). After 4 weeks of treatment, the experimental group showed significantly higher ABC score and MBI score than those of control group (P<0.05). There were no adverse reactions in either group.

VRT is an effective and safe intervention for improving dizziness symptoms and balance function, daily living ability, psychological well-being in patients with chronic dizziness. It holds significant clinical value and warrants further application in rehabilitation settings.
