Title of the study EEFECTIVENESS OF LEE SILVERMAN VOICE TREATMENT (LSVT) BIG AND STRENGTH  TRAINING ON BALANCE, PHYSICAL ACTIVITY AND RISK OF FALL IN  ELDERLY POPULATION : QUASI EXPERIMENTAL STUDY. The study is a one group experimental study with 35 sample size comprising of older adults age above 65 years with mild balance impairment . aim of the study is to assess the effectiveness of LSVT Big and strength training on balance, physical activity and risk of fall in elderly population. it is a 4 weeks of experimental study with 3 days of intervention for 1 hour consisting of 45 mins of LSVT BIG training and 15 mins of strength training. consent will be taken from the participants before the study program. LSVT BIG training consists of exercises like sustained movements  as seated floor to ceiling seated side -to- side . and directional repetitive movements as forward step sideways step backward step and lastly walking with bigger steps . all the exercises has to be done for 8-10 repetition. strength training exercises includes isometric contraction of quadriceps group of muscles and hamstring group of muscles for 10 second holds for 10 times. The screening will be done using MMSE scale for measuring level of cognition and level of balance will be measured using Berg Balance Scale. The pre intervention data will be collected using outcome measures BBS, POMA scale, TUG scale and PASE scale. Then intervention will be started and training will be given for 1 hour per session for 3 days every week for 4 weeks and home exercise program will be suggested with same exercises. After 4 weeks the post data will be taken using the same outcome measure and the data will be sent for statistical analysis to the statistician and the result will be verified. The findings of the study can help  clinicians and caregivers provide more effective and targetted intervention to improve balance, physical activity and prevent risk of falls in elderly population.The findings of this study can have significant implications for clinicians and caregivers who work with elderly populations. Here are some ways that
