The Hidden Link Between Shoulder Internal Rotation and Tennis Elbow

Tennis elbow is more than just an athlete's ailment; it's a common condition that can affect anyone engaging in
repetitive arm movements. While the pain centres around the elbow, the root cause may be higher up - in the shoulder.
Specifically, shoulder internal rotation can place excessive stress on the arm muscles and tendons, leading to or worsening tennis elbow symptoms. Understanding this connection is key to effective treatment and prevention.
In this article, we'll explore how shoulder internal rotation contributes to tennis elbow and how targeted interventions can provide relief.
Understanding Tennis Elbow and Shoulder Internal Rotation
What Is Tennis Elbow?
Tennis elbow, or lateral epicondylitis, is characterised by pain on the outer part of the elbow due to overuse of the forearm muscles and tendons. These muscles are responsible for extending the wrist and fingers, and repetitive strain can lead to micro-tears in the tendons, causing inflammation and pain.
What Is Shoulder Internal Rotation?
Shoulder internal rotation occurs when the upper arm bone (humerus) rotates inward toward the body's centerline. This posture is common in activities that involve forward-reaching motions but can become problematic when it becomes habitual due to poor ergonomics or muscle imbalances.
How Shoulder Internal Rotation Contributes to Tennis Elbow
- Biomechanical Misalignment: Internal rotation of the shoulder alters the natural alignment of the arm, increasing stress on the elbow joint during movement.
- Muscle Imbalances: This posture tightens the front shoulder and chest muscles while weakening the upper back muscles. The forearm muscles compensate for this imbalance, leading to overuse.
- Increased Tendon Load: The altered mechanics place additional load on the tendons connected to the lateral epicondyle of the elbow, exacerbating pain and inflammation.
Effective Exercise
Twist Bicep Curls
One of the most effective exercises to combat the effects of shoulder internal rotation is the twist bicep curl.
Benefits:
- Strengthens Forearm and Bicep Muscles: Targets muscles strained by poor shoulder posture.
- Improves Supination: Enhances the outward rotation of the forearm, reducing elbow stress.
- Corrects Muscle Imbalances: Promotes balanced muscle development in the arms.
How to Perform:
- Starting Position: Stand with feet shoulder-width apart, holding dumbbells at your sides with palms facing your thighs.
- Curl Movement: As you lift the weights, rotate your wrists outward so your palms face upward by the time they reach shoulder level.
- Lowering Phase: Slowly lower the weights, rotating your wrists back to the starting position.
- Repetitions: Perform 2-3 sets of 10-12 reps with controlled movements.
