Intervention type: OTHER
Intervention: Position Sense
Description: Knee position sense was evaluated with a Acumar dual digital inclinometer. Each participant was asked to wear shorts and to lie down in supine position treatment table. The lower extremity of the participant was positioned in neutral for the knee flexion movement. The placement of the digital inclinometer's attachment was the lateral ridge of the femur and tibia. We actively assisted the participant's knee to the target angle and asked the participant to hold it there for 5 seconds before returning the knee to the starting position. After returning to the starting position, participants attempted to repeat the previously attained angle. Participants indicated verbally when they felt they had reached the angle and held their position. This procedure was repeated 3 times for each limb (non-dominant and dominant). We measured the absolute difference between the target angle and the observed angle and calculated the absolute error score by averaging the 3 trials.

Intervention: Balance
Description: To measure postural stability and Limits of Stability this study used a balance device, the Biodex Balance System.~Postural Stability: The participants were focused on a characteristic dot (COP, centre of pressure) on the monitor screen. The participant's task was to balance the body in such a way that the dot was in the centre of a circle displayed on the monitor at the point of intersection of the coordinate axes. Test consisted of three 20-second trials, each separated by 10-second breaks. Measurements were repeated three times while their eyes were open/close and analyzed by calculating the average value of measurements.~Limits of Stability: The participants are asked to complete the directional tasks displayed on a screen as quickly as possible, with the directions displayed at random. A total of 3 tests were performed, at intervals of 10 s.

Intervention: Dual Task Performance
Description: The timed up and go test (TUG) was used in the evaluation of dual task performance. For this test, participants were seated on a standard armless chair and a cone was placed 3 meters away from the chair. Participants were instructed to stand up and (1) walk towards the cone, (2) turn around the cone, (3) walk back to the chair, and (4) sit back on the chair. It was stated that patients should walk without running but as fast as possible. TUG test was performed initially without task, and then with cognitive and motor tasks, respectively. Cognitive task given during the test is counting three backwards from 100 or counting the names starting with the letter A, and motor task given is to carry three glasses of water on a tray. The time elapses between standing up from the chair and sitting back to chair was recorded as the test result. As time increases, dual task performance decreases.
