reported no change in patients’ risk of falling or use of an assistive device despite participation in a vestibular rehabilitation program.22 Krebs et al. stud- ied 124 subjects diagnosed with unilateral and bilat- eral dysfunction and found greater improvement in gait velocity and stability compared to the control group at the end of the 6-week vestibular rehabilita- tion program. In the subgroup analysis, both groups were found to have received equal benefit from ves- tibular rehabilitation though the unilateral vestibular hypofunction group was more functional at baseline than the bilateral vestibular hypofunction group.6 In our study, we found that vestibular rehabilitation was equally effective on postural stability, dynamic balance, and disability, indicating that all unilateral and bilateral vestibular dysfunction patients should be highly encouraged to participate in an exercise program to improve their balance and minimize their disability. However, contrary to our results, previous studies have reported limited response to vestibular rehabilitation in bilateral vestibular failure, with limited prognosis
