Postural sway will be evaluated with Cyst Force Plate Balance device. This device is a precision device that provides objectively measurable data. Thanks to its movable platform, it can measure in all directions. Participants will be asked to stand on the platform assessing their body oscillations. They will be asked to look at a still picture on the wall with their arms at the iliac and eyes directly opposite them. Individuals will be asked to keep their designated positions for 30 seconds. At the end of the specified period, the data obtained from the device will be saved. Before and after the neuromuscular fatigue test postural sway will be evaluated.
