The effect of a 12-week vestibular rehabilitation program on postural stability as measured by computerized dynamic posturography in a Parkinson's Disease population

Abstract

Purpose: To examine the effect of a 12-week vestibular rehabilitation therapy (VRT) program on postural stability outcome measures in Parkinson's disease (PD) patients. Methods: Thirteen PD subjects (Hoehn and Yahr '"on" stage 2-3) completed a 12-week physiotherapist VRT program. Measurements of postural stability were assessed at baseline and after completing VRT (Computerized Dynamic Posturography, Functional Reach Test, (FRT), Berg Balance scale (BBS), Activities-specific Balance Confidence scale (ABC), and Subjective Impressions Quality of Life scale) in a PD population. Results: 1) A statistically significant increase in the primary outcome of the equilibrium composite score (p=0.04). 2) An increase in FRT, ABC scale, and several aspects of the Subjective Impressions Quality of Life scale (balance, posture, and feeling of physical well-being) Conclusion: VRT appears to help improve postural stability in PD patients.
