Scapular Stability

Scapular stability refers to the ability of the shoulder blade (scapula) to stay properly aligned and move smoothly on the chest wall during arm movements. It depends on the strength and coordination of muscles around the shoulder, including the upper back, shoulder, and chest. Maintaining scapular stability is essential for efficient, pain-free arm movements and helps prevent shoulder injuries. When stable, the scapula provides a solid foundation for shoulder function, supporting activities like lifting, throwing, or reaching. Proper stability involves muscle balance, control, and timing, ensuring the shoulder moves safely and effectively.
