The shoulder external rotation at 45° abduction targets the rotator cuff muscles, particularly the infraspinatus and teres minor, to improve shoulder strength and stability. Performing the movement in this position mimics functional arm use while reducing stress on the joint, making it valuable for injury prevention, sports performance, and rehabilitation. It supports overhead activities by enhancing control and resilience of the shoulder.
- Setup: Anchor the theraband securely at waist height. Stand facing the anchor point with feet hip-width apart. Hold the band with the working arm, ensuring light tension in the band.
- Starting Position: Raise the working arm to 45° abduction (partway between your side and shoulder height), keeping your elbow bent at 90°. Ensure your shoulder blades are drawn slightly back and down.
- Engage: Keep your torso upright and shoulders level, avoiding any shrugging.
- Movement: Slowly rotate your forearm outward, pulling the band away from the anchor point, while keeping your upper arm steady. Move until you reach your comfortable range or feel resistance.
- Return: Gradually control the band as you bring your arm back to the starting position.
- Breathing: Exhale as you rotate outward and inhale as you return.
- Complete repetitions as prescribed by your physiotherapist.
