2.5.1. To improve gaze stability.
head movements
Patients were instructed to keep their eyes on a target that was stationary while being asked to continuously move their head horizontally, that is, side to side, for 1 minute. Afterward, they were instructed to perform the head movements vertically, that is, up and down, while the target remained stationary. The patients repeated their head movements as fast as they could while keeping their focus on the target. The patients were continuously monitored to ensure that they maintained gaze stability during each task. The patients were then instructed to keep their heads stationary and follow a slow-moving target. The target kept moving in different directions, including left, right, upward, and downward, while the head was held in a neutral position. The study duration was the same for all participants. Initially, these exercises were performed for 1 to 4 weeks; after that, for 5 to 8 weeks, they were advanced by adding more challenging tasks, such as standing from sitting to standing, separating feet and then combining them, and walking between them.
