Effects of Power Ball on Proximal Muscle and Refractive Errors in Developmental Delay.

This group will receive conventional physiotherapy, which will consist of manual resistance-based neck strengthening exercises. The exercises will last 30 minutes apiece and cover cervical flexion, extension, side flexion, side flexion with rotation, and pure rotation with moderate resistance. The power ball's effect on proximal muscle control and refractive error in children with developmental delays will also be discussed.

"Group B: In addition to standard care, this group will engage in power ball exercises for neck stability and strengthening. Gradually, the resistance will rise.~Three mints in each position for a total of fifteen mints of ball exercises. At first, Powerball progressively strengthened the muscle and reduced the pain , and with continued development, allowed them to move in a pain-free range."
