Participants who will be randomized to the otago exercise program will receive an exercise program that include 17 exercises 5 for strengthen , 12 balance exercise and will starting and ending with a 2-to 3-min warm-up/cool-down period OEP consists of strengthening and balance exercises. Strengthening of ankle plantar and dorsiflexors, knee extensors and flexors, and hip abductors will be focused in traises. The progression will be performed by increasing the duration and then weights. Stair walking, sit-to-stand, heel-to-toe walking backward, toe walking, heel walking, one-leg stands, tandem walking, tandem stance, sideways walking, turning around, walking backward, walking, and knee bends were used for balance exercises. Three levels will be used for balance exercises: Level 1 will be 2 hands holding on, Level 2 will be one hand holding on, and Level 3 will be no hands or support. The individuals will repeat exercise 10 times session twice a week over 8 weeks

Participants who will be randomized to the HVRT will receive an exercise program targeting the lower limbs, to be performed twice a week for 8 weeks. Participants will be instructed to perform the exercises in a rapid and explosive manner such that all repetitions for each shortening phase (concentric activation of the muscle) will be performed as quickly as possible while the lengthening phase of the muscle (eccentric phase) will be controlled over 2-3 s

Participants will be instructed to perform the exercises in a rapid and explosive manner such that all repetitions for each shortening phase will be performed as quickly as possible while the lengthening phase of the muscle will be controlled over 2-3 s The exercise will be done (bilateral leg press, step up, sit to stand, calf raise). The 8 weeks will be divided in three phases .

OEP consists of strengthening and balance exercises. Strengthening of ankle plantar and dorsiflexors, knee extensors and flexors, and hip abductors will be focused in this program. Ankle weight cuffs (1-3 kg) provide resistance for hip and knee exercises. The ankle plantar and dorsiflexors will be strengthened by performing heel and toe raise .

plantar and dorsiflexors will be strengthened by performing heel and toe

The scale will evaluate an individual's ability to maintain their balance while performing functional activities. It includes 14 items and each section is scored between 0 (worst) and 4 (best), and measures level of dependence/independence in positions such as standing from sitting, standing with feet together, standing in full balance position, balancing on one leg, as well as ability to change positions. High BBS score will indicate good balance. Participants will be classified based on BBS score as high fall risk, balance disorder (0-20 points), moderate fall risk, acceptable balance (21-40 points), and low fall risk, good balance (41-56 points)

Timed Up and Go is a commonly applied screening tool that helps to identify patients that are likely to fall. The test will be conducted with the following rules: at first, the tested person will sit on a chair with their back on the backrest; then, on the command "START," they will get up and walk 3m (on a level floor at a normal pace); next, having crossed a line, they will take a 180-degree turn and will come back to the chair to sit down again. The time will be measured by a stopwatch when the patient is instructed on how the test should be done . A test result less than 10 sec indicate low risk of fall , 10-19 sec -a moderate risk of fall and more than 19 -ahigh risk of fall
