Computer-assisted training as a complement in rehabilitation of patients with chronic vestibular dizziness--a randomized controlled trial.

Objective: To compare a computer-assisted home exercise program with conservative home-training following printed instructions in the rehabilitation of elderly patients with vestibular dysfunction.

Design: Single-blind, randomized, controlled trial.

Setting: Geriatric department of a university hospital.

Participants: Patients with chronic dizziness due to vestibular dysfunction (N=63) were randomly assigned to either rehabilitation in the clinic followed by computer-assisted home exercises (intervention group: n=32) or rehabilitation in the clinic followed by home exercises according to printed instructions (control group: n=31).

Interventions: Patients in the intervention group received assisted rehabilitation by a computer program.

Main Outcome Measures: Measurements at baseline and at 8 and 16 weeks were compared. These included the One Leg Stand Test, Dynamic Gait Index, Chair Stand Test, Motion Sensitivity Test, Short Form-12, Dizziness Handicap Inventory, and visual analog scale.

Results: Both groups improved significantly during 16 weeks of rehabilitation. However, neither t tests nor repeated-measures analysis of variance demonstrated any significant differences between the 2 groups. The overall compliance rate to computer program exercises during 16 weeks was 57%.

Conclusions: A computer-assisted program to support the home training of elderly patients with vestibular dysfunction did not improve rehabilitation more than did printed instructions.
