BRACE include combination of exercises including, Balance, Resistance, Aerobic, Cognition Exercises.

Otago's protocol is combination of warm up, strengthening, balance and flexibility exercises.

Study will be conducted after the approval of Ethical review board. The BRACE exercise training would be perform in 4 times a week for 12 weeks, lasting approximately 40-50 minutes each time. Week 1-3 : Balance: Romberg, tandom standing, single leg stance Resistance: chair rise Aerobic exercises: 6mint walk Cognitive: count reverse from 50 Week 4-6: Balance: Sit to stand, functional reach, Tug Test Resistance: stair climbing Aerobic Exercises: Marching in space Cognitive: Remember 5 words, spell backward, remember 5 animals Week 7-9: Balance: Perturbation, throwing a ball, kicking a ball Resistance: Floor transfer, squatting Aerobic Exercises: Cycling Cognitive: Count even number from 1-50, calculation, addition, subtraction, multiplication division Week 10-12: Balance: Combination of All Resistance: Combination of All Aerobic Exercises: 6 minutes' walk test, marching steps, cycling Cognitive: Combination of all

changes from the baseline, Berg balance scale (BBS) is used for assessment of balance and fall risk, Higher scores on the BBS indicate greater independence and better ability to balance. In contrast, lower scores indicate a greater fall risk Items DESCRIPTION SCORE (0-4) Sitting to standing, Standing unsupported, Sitting unsupported, Standing to sitting, Transfers , Standing with eyes closed , Standing with feet together, Reaching forward with outstretched arm, Retrieving object from floor, Turning to look behind, Turning 360 degrees, Placing alternate foot on stool, Standing with one foot in front, Standing on one foot, TOTAL __/56

changes from the baseline, Timed up and go test is used for the assessment of falls risk among the elderly population. The Timed "Up and Go" (TUG) Test measures, in seconds, the time is taken by an individual to stand up from a standard armchair (approximate seat height of 46 cm, arm height 65 cm), walk a distance of 3 meters (approximately 10 feet), turn, walk back to the chair, and sit down. Normal healthy elderly usually complete the task in 10 seconds or less. Very frail or weak elderly with poor mobility may take 2 minutes or more. Clinical guide: <10 seconds = normal <20 seconds = good mobility, can go out alone, mobile without a gait aid <30 seconds = problems, cannot go outside alone, requires a gait aid A score of more than or equal to 14 seconds has been shown to indicate a high risk of falls.

The Montreal Cognitive Assessment (MOCA) is a cognitive screening instrument developed to detect mild cognitive impairment (MCI). It is a simple 10 min paper and pencil test that assesses multiple cognitive domains including memory, language, executive functions, visuo-patial skills, calculation, abstraction, attention, concentration, and orientation.

Scores on the MoCA range from zero to 30. A score of 26 and higher is considered normal.

In the initial study data, normal controls had an average score of 27.4. People with mild cognitive impairment (MCI) scored an average of 22.1. People with Alzheimer's disease had an average score of 16.2.
