Participants will be evaluated with the "Postural Stability Test", "Limits of Stability Test", "Sensory Integration Test" and "Bilateral Comparison Test" within the AlBalance Balance Evaluation System. To calculate the test-retest reliability of the device, these measurements will be made by the same evaluator, will last 30 seconds and will be repeated a total of 3 times with a 1-minute rest between tests. These measurements will be repeated after 7 days to evaluate reliability. Then, parallel clinical tests will be applied to the participants, "Functional Reaching Test" and "One Leg Standing Test".

Stability indices represent fluctuations around the zero point established before testing when the platform is stable. With the "Postural Stability Test", the anteroposterior, right-left, and general stability indexes of the cases will be recorded. During the test, participants will be asked to stand on the force platform with their feet in a comfortable position, arms at their sides, and palms facing toward the thighs. All measurements will be made with bare feet, and without shoes, and foot position will be recorded using coordinates on the platform's grid to ensure consistency in testing. The participant will be asked to stand still looking at the screen in front of him for 30 seconds. There will be a 1-minute rest break between measurements and they will be performed 3 times. The participant's Postural Stability will be assessed with Postural Stability Test.

In this test, the participant stands on force plates and deliberately shifts his or her body weight in the direction indicated on the screen without lifting his or her feet off the ground. This protocol measures various movement characteristics in 8 different directions: front, forward/right, right, back/right, back, back/left, left, and forward/left. During the test, participants will be asked to stand on the force platform with their feet in a comfortable position, arms at their sides, and palms facing toward the thighs. Direction control (%) and test times (sec) in all directions of the participants, who will move in 8 different directions sequentially, will be recorded. There will be a 1-minute rest break between measurements and they will be performed 3 times. The participant's Limits of Stability will be assessed with Limits of Stability Test.

The test decides which of the visual, vestibular, and proprioceptive information is used to provide orientation to maintain balance in different situations. During the test, visual and proprioceptive stimuli are disrupted and the ability to maintain the center of gravity is evaluated. The test consists of 4 different situations that gradually become more difficult: Situation 1: Eyes open; firm surface Situation 2: Eyes closed; firm surface Situation 3: Eyes open; foam surface Situation 4: Eyes closed; foam surface All measurements will be made with bare feet, and without shoes, and foot position will be recorded using coordinates on the platform's grid to ensure consistency in testing. The participant will be asked to stand still looking at the screen in front of him for 30 seconds. There will be a 1-minute rest break between measurements and they will be performed 3 times. The participant's Sensory Integration will be assessed with Sensory Integration Test.
