Efficacy of Four Square Step Test and Modified Dynamic Gait Index to Predict the Falls in Parkinson’s Disease: A Comparative Study

Abstract

Introduction: This study evaluated the efficacy of Four square step test (FSST) and modified dynamic gait index (mDGI) in patients with Parkinson's disease to evaluate balance. In this study 50 individuals with Parkinson's disease were assessed according to Hoen Yahr scale (grades between 1to 3), were subjected to FSST and mDGI. Results: FSST and m DGI scores were taken of the same patient. and sensitivity and specificity were also calculated. Both these scales show a highly significant negative correlation with each other (. r=-0.88, P<0.001) Conclusion: Thus the study concluded that both FSST and MDGI are equally effective for evaluating balance in individuals with Parkinson's disease.
