• Pain Referral Pattern
Pain often refers to the top of the shoulder and may radiate down the side of the arm, sometimes reaching as far as the elbow.
It can cause deep, achy pain in the shoulder joint, particularly with arm movement, and may limit range of motion in the shoulder.
Pain Pattern
• Potential Causes
• Overuse or repetitive activities involving arm movement, such as lifting, reaching, or throwing.
• Poor posture, especially with rounded shoulders.
• Trauma or injury to the shoulder.
• Muscle imbalances between the supraspinatus and other shoulder muscles.
• Prevention Tips
• Use proper techniques during activities involving arm movement to avoid overloading the supraspinatus.
• Incorporate regular stretching and strengthening exercises for the shoulder and upper back muscles.
• Maintain good posture and shoulder alignment, especially during upper body activities.
• Gradually increase workout intensity to avoid sudden strain.
• Ensure balanced strength training to avoid muscle imbalances.
