Closed Chain Exercise Group

Represents fluctuations from the horizontal around the mediolateral axis. Mediolateral sway and anterior-posterior stability will record in the double-leg stance for 20 seconds with Biodex Balance System. The feet are placed in a comfortable position for patients, and the center of gravity was recorded in the system to begin the test. Each test will repeat 3 times. A higher sway index indicates a decrease in postural stability.

A 10-meter walking test will be used to evaluate walking.

The HJHS is derived from a physical examination of the index joints by a health care professional who should have training and expertise in the conduct of a detailed musculoskeletal (MSK) examination. It is a measure of joint health and sits within the World . The current HJHS version 2.1 comprises an assessment of specific features, or items, of the six index joints and an assessment of global gait. For each of the six joints, the following items are scored: swelling (scored 0-3), duration of swelling (0-1), muscle atrophy (0-2), crepitus on motion (0-2), flexion loss (0-3), extension loss (0-3), joint pain (0-2), and strength (0-4). The maximum score for an individual index joint is 20. Gait is scored 0 to 4. The maximum HJHS total score is 124, with a higher score indicating worse joint health.

The Single leg stance test (SLTS) measures static balance by challenging participants to stand unassisted on 1 leg. İndividuals stand for 30 or 45 seconds with their arms crossed across their chest or with their hands touching their hips. The SLST will completed with or without shoes and using the dominant or nondominant leg.

The SLST will completed first with eyes open and then with eyes closed. Participants are timed as soon as their foot leaves the floor and stops once the foot touches the ground, the supporting foot shifts, their suspended foot touches the supporting leg, their eyes open in the eyes-closed trials, an arm is uncrossed or stops touching their hip, or if the maximum allotted time is reached.

Three trials per condition are recorded, and either an average is calculated or the longest time is used. The SLST performance is reported in seconds (continuous) and requires a stopwatch.
