Home-based Vestibular Rehabilitation: A Feasible and Effective Therapy for Persistent Postural Perceptual Dizziness (A Pilot Study)

<jats:sec><jats:title>Introduction:</jats:title><jats:p> Persistent postural-perceptual dizziness (PPPD) is a chronic functional vestibular disorder where there is persistent dizziness or unsteadiness occurring on most days for more than 3 months duration. Treatment recommendations for PPPD include vestibular rehabilitation therapy (VRT) with or without medications and/or cognitive behavioral therapy. </jats:p></jats:sec><jats:sec><jats:title>Objectives:</jats:title><jats:p> This paper is a pilot study designed to compare the effects of Bal Ex as a home-based VRT on the quality of life (EQ-5D), dizziness handicap (DHI) and mental health (DASS-21) against hospital-based VRT. </jats:p></jats:sec><jats:sec><jats:title>Design:</jats:title><jats:p> This was an assessor-blinded, randomized controlled pilot study where PPPD patients were randomly selected to undergo Bal Ex, the home-based VRT (intervention group) or hospital-based (control group) VRT. The participants were reviewed at 4 weeks and 12 weeks after the start of therapy to assess the primary endpoints using the subjective improvement in symptoms as reported by patients, changes in DHI scores, DASS-21 scores and EQ5D VAS scores. </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> Thirty PPPD patients successfully completed the study with 15 in each study group. Within 4 weeks, there were significant improvements in the total DHI scores as well as anxiety levels. By the end of 12 weeks, there were significant improvements in the DHI, DASS-21 and EQ5D. The degree of improvement between Bal Ex and the control was comparable. </jats:p></jats:sec><jats:sec><jats:title>Conclusion:</jats:title><jats:p> VRT is an effective modality in significantly improving quality of life, dizziness handicap, depression, and anxiety levels within 3 months in PPPD. Preliminary results show Bal Ex is as effective as hospital-based VRT and should be considered as a treatment option for PPPD. </jats:p></jats:sec>
