Reliability & Validity of Mini-BESTest Scale Compared with POMA Scale to Assess Balance & Coordination in Patients with Parkinson’s Disease

Abstract

Background: Parkinson’s disease (PD) is a progressive neurodegenerative disorder of the aging population and affects mobility, locomotion, and balance. There are multiple tools available for assess balance parameters in PD. BBS, POMA, Mini-BESTest scale and PIGD are most important and recommended tools to assess balance parameters. Mini-BESTest scale assess all 4 components of the balance parameters but psychometric properties of this scale on parkinson’s disease population was not found. Need of the study: There is no valid data available for reliability and con-current validity of Mini-BESTest scale on Indian population of PD.Methodology61 patient of PD stage 1 to 3 were included in this study. They were assessed by two scale (1=Mini-BESTest scale, 2 = Tinetti Performance Oriented Mobility Assessment scale(POMA)) for test-retest reliability, interrater reliability and con-current validity by 2 different raters. The data was analysed with ICC value and Cronbach’s Alpha for reliability and spearmen’s correlation for validity. Result: Mini-BESTest scale has excellent test-retest and interrater reliability and moderate to high correlation for con-current validity. Conclusion: Mini-BESTest scale is valid and reliable tool for assess balance in PD. Funding Statement: None to declare. Declaration of Interests: None to declare.
