Ankle proprioception will be measured with the participant's knees lying on their back in a semi-flexed position. The test will be performed for 10 degrees of dorsiflexion and 20 degrees of plantar flexion, respectively. Measurements will be made with an electrogoniometer device. The difference between the required degree and the degree in the position brought by the participant will be taken as evaluation data.

Lumbal region proprioception measurement will be made with lumbar flexion and extension movements. The participant will be asked to perform active lumbar flexion. Then, lumbar flexion movement will be performed up to 50% of the measured active flexion angle and it will be requested to stay in this position for 10 seconds. After the participant returns to the upright position, he will be asked to come back to the learned angle and the difference in angle will be taken as evaluation data. The same procedure will be done for the lumbar extension movement.

Postural control evaluation will be done with the Gyko-Microgate software. Bluetooth data transmission enables real-time measurements to be transferred directly to the computer. After the device was placed on the body of the person thanks to the wearable vest, a connection was established with the software on the computer.

To evaluate postural control, with eyes open, eyes closed and eyes open on a hard surface, accompanied by a cognitive dual task; On soft ground, with eyes open, eyes closed and eyes open, the person is asked to remain in a stable balance for 30 seconds, accompanied by a cognitive dual task. For the cognitive dual task, two countdowns and K-A-S verbal fluency exercises will be performed in each assessment. As a result of each evaluation, data on ellipsoid area, anteroposterior velocity, anteroposterior distance, mediolateral velocity, and mediolateral distance will be obtained.

Dynamic balance evaluation will be done with the Gyko device. To evaluate dynamic balance, walking with eyes open on hard ground, walking with cognitive dual task on hard ground; walking with eyes open on soft ground, and cognitive dual task on soft ground will be evaluated. The walking distance is determined as 6 meters. The first 1 meter and the last 1 meter will not be taken into consideration. The measurement will start at the 1st meter and end at the 5th meter. The measurement will be carried out at a distance of 4 meters. As a cognitive task, the participants will be given the task of counting down by two and K-A-S verbal fluency. As a result of each evaluation, data on the ellipsoid area, anteroposterior velocity, anteroposterior distance, mediolateral velocity, and mediolateral distance will be obtained.

The Timed Get Up and Walk Test is used to assess balance and fall risk. The participant stands up from the chair, walks 3 meters, turns back, and sits back on the chair. The time elapsed during these phases was recorded.

In our study, the patient will be asked to start the test after the Gyko device is fixed with a wearable vest. During the test, data on the ellipsoid area, anteroposterior velocity, anteroposterior distance, mediolateral velocity, and mediolateral distance will be taken.

MoCA is a 10-minute scale that measures global cognitive skills. It includes items consisting of attention and concentration, executive functions, memory, language, visuospatial skills, abstract thinking, calculation and orientation skills. The lowest score that can be obtained from the scale is 0, and the highest score is 30. Scores of 21 and below indicate the presence of cognitive impairment.
