The Otago Exercise Program (Group A) includes specific exercises for strength and balance improvement. These exercises were conducted three times a week. Each training session lasted for 35-40 minutes.

Participants will be instructed to watch a video on a 22-inch screen positioned 1 meter away from them, while comfortably seated in a chair with armrests. They are not allowed to follow along or engage in any movement while watching the video. The duration of the video viewing will be 17 minutes (1 minute for each video), followed by a 35-minutes of exercise (2 minutes maximum per session).

The Otago Exercise Program is composed of strength training and balance training. Strength training consisted of flexion and extension exercises of the knee, ankle, and toe joints, as well as hip opening exercises to strengthen the sides of the pelvis. Balance training consisted of walking backwards, walking in a figure of eight, heel-toe walking, standing on one leg, walking on the heels, walking on the toes, heel-toe walking backwards, standing up from a sitting position, and walking up stairs. Otago exercise program will be performed with action observation train will be instructed to watch a video on a 22-inch screen positioned 1 meter away from them, while comfortably seated in a chair with armrests. They are not allowed to follow along or engage in any movement while watching the video.

The BBS is constructed to assess balance ability of older people and identify their risk for falling. The BBS is a 14-task scale that requires subjects to maintain their balance in positions and tasks of increasing difficulty. Specific components of the BBS parallel some gait requirements such as unsupported leg stance and standing with 1 foot in front of the other. Other components address tasks such as rising to stand or standing unsupported. It has an ordinal scale of 0 to 4 points (best performance, 56). The BBS is well documented and has strong psychometric properties for people with stroke. For subjects with stroke, the interrater and intrarater reliability were found to be .97 and .98, respectively. A score of 44 or less has been found to indicate a higher risk of falls.

The DGI is 8 items test that includes walking, walking while changing speed, walking while turning the head horizontally and vertically, walking with pivot turn, walking over and around obstacles, and stair climbing. The scoring of the DGI is based on a 4-point scale ranging from 0 to 3, with 0 indicating severe impairment and 3 indicating normal ability. The best performance total score is 24. A low composite DGI score thus indicates greater impairment in functional mobility. The DGI has been found to be reliable and valid for older people (.96) (ICC.98). Scores of or below 19 points on the DGI indicate a risk of falling in older people and a score of less than 12 points discriminated between fallers and non-fallers.

The FIM instrument is a minimum data set that measures 18 functional activities, 13 of which involve motor activities and 5 of which involve cognitive activities. The tool has a 7-level scale for scoring each of the items. For example, a score of 1 means that a patient is dependent and is able to provide less than 25% of the effort for a given activity, and a score of 7 means that a patient is completely independent and can perform an activity without assistive devices in a safe and timely manner.
