Introduction: This study evaluated the efficacy of Four square step test (FSST) and modified dynamic gait index (mDGI) in patients with Parkinson__ampersandsignrsquo;s disease to evaluate balance. In this study 50 individuals with Parkinson__ampersandsignrsquo;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= __ampersandsignndash; 0.88, P__ampersandsignlt;0.001) Conclusion: Thus the study concluded that both FSST and MDGI are equally effective for evaluating balance in individuals with Parkinson__ampersandsignrsquo;s disease.
