Background: Parkinson disease (PD) is a progressive neurodegenerative movement disorder caused by a lack of dopamine production in the substantianigra. The cardinal features of this disorder include bradykinesia, gait disturbance, rigidity, and tremors. Method: A Randomized control trial was conducted of the patients consulted to SKH & diagnosed with Parkinson's disease. Selection of 120 patients based on the criteria and informed consent was taken from the participants and divided as Experimental group & control group. Pre and Post Evaluation of patient was done with BBS and UPDRS after 2weeks. Result: The mean difference of BBS in conventional group was 3.633±3.16 whereas in Wii Fit group was 5.05±3.16 To compare the mean difference between two groups, Independent t-test was applied and its p-value was obtained. There was statistically significant difference found between these two groups (P value 0.016). The mean difference of UPDRS in conventional group was -2.63±2.66 whereas in Wii Fit group was -4.53±3.33 To compare the mean difference between two groups, Independent t-test was applied and its p-value was obtained. There was statistically significant difference was found between these two groups (P value 0.001). Conclusion: Both the treatment method were effective in Improving balance in Parkinson’s disease but the effect of Wii fit balance training is more in comparison to Conventional balance training.
