The Asynchronous Exercise Group will be conducted with a video-based structured exercise program. For the asynchronous video-based group, a closed channel will be created on Youtube that only patients can access, and the exercises will be uploaded to the system asynchronously. In the asynchronous exercise group, how each exercise is performed will be shown in detail by the physiotherapist in the video content.

One of the tests that will be used to test the functional capacity of individuals is the 30-second sit-to-stand test. During the test, patients will be asked to sit with their hands crossed over their shoulders and their feet touching the ground, and to do a full sit-to-stand in this position. The number of correct standing ups within thirty seconds will be recorded as the test score.

In order to evaluate the functional capacity of the patients, they will be asked to quickly climb up and down 10 stairs and the test score will be recorded in seconds.

Individuals will be asked to maintain a half squat position on a hard surface, feet shoulder-width apart, hands crossed over shoulders, without shoes, in order to assess their functional capacity. The duration of the squat will be recorded in seconds.

They will be asked to run between two cones in a 20-meter corridor, paying attention to the beeps coming from the voice recorder. The test will start at a slow running speed, and the speed will gradually increase every minute. If individuals cannot reach the cone line the first time when the beep sounds, they will be asked to run in the opposite direction. At the end of the test, the total number of completed laps will be taken as the score, including the laps that were not completed.

In order to assess the balance of the subjects, they will be asked to stand on one leg with their hands crossed on their chest and the knee joint flexed at 90 degrees. It will be repeated for both the right and left extremities. The test score will be recorded in seconds.

Individuals will be asked to turn sideways to the wall, flex their arm 90 degrees from the shoulder, and make a fist. The third metacarpophalangeal joint will be marked as the starting point and individuals will be asked to reach forward as much as possible without taking a step or bending their knees. The third metacarpophalangeal joint alignment will be marked again at the last point reached. The distance between the two marked points will be recorded in centimeters.

Balance skills will be tested during postures such as squat posture on K-Force plates, single leg and double leg postures with eyes open and closed.

The walking parameters of individuals will be evaluated with the Digitsole Smart Insole system. Digitsole Pro® smart insole is a valid and reliable measurement tool that allows the individual to evaluate the walking parameters of the individual by being placed inside the shoe worn by the participant. Individuals will be asked to walk wearing smart insoles with sensors inside their shoes. The spatio-temporal and kinematic walking parameters of individuals will be evaluated with the Digitsole Pro system.

The FitnessGram test battery is a valid and reliable measurement method. Its components include functional capacity, flexibility, muscle strength, body composition and muscular endurance. The FitnessGram test battery will include the Sit-up test, Push-up test, Sit-and-reach test, Trunk lift test and Pacer test. The sit-up test will begin with the patient in a supine position with the knees flexed approximately 140 degrees and the knees slightly apart. The patient will be asked to do sit-ups in accordance with the commands from the voice recorder while the arms are extended next to the body, with the shoulder blades slightly lifted off the ground. The number of sit-ups will be recorded.

The push-up test, individuals will be asked to do push-ups in accordance with the commands from the device with the help of elbow flexion and extension while in the prone position. The number of push-ups done correctly will be recorded. The push-up test provides information about the endurance of the upper extremity muscles.

The Sit-Reach test: A plate with a length of 50 cm and a width of 45 cm is placed on a box with a length of 35 cm, a width of 45 cm and a height of 32 cm. During the test, individuals will reach forward with their hands as far as they can, with one knee in extension and the other knee in flexion in front of the test box. The evaluation will be repeated for the other side. At the end of the test, the distance the individual reaches will be recorded in cm

The trunk lift test will be performed to evaluate trunk extensor muscle endurance. The test will begin with the individual's hands placed under the thighs in a prone position on a flat surface. The subjects will be asked to slowly lift their trunks upwards with their heads. At the end of the test, the distance between the ground and the subjects' chin will be recorded in cm.

Body mass index will be calculated for body composition.

Patients will be asked to mark their pain level on a 100 mm line. 0 mm on the line represents "no pain" and 100 mm represents "very severe pain."
