Active_comparator: VR group

During the exercise, games will be selected from the movements that focus on upper extremity function and require the use of both extremities. These functions will be to grasp the object with both hands, to throw the object, and to provide the object's rotation by revealing the hand's supination-pronation movement. During these movements, the image of the healthy side will be mirrored to the affected side. Before each exercise, what kind of movement requested from the patient will be shown in the VR environment.

Active_comparator: Control group

In addition to mirror therapy, Bobath therapy, walking exercises, upper extremity active exercises, proprioceptive neuromuscular facilitation techniques, which are traditional physical therapy and rehabilitation methods, will be applied to the control group. In addition, a virtual environment monitoring session will be conducted in non-interactive virtual environments for 10 minutes after their treatment.
