A high school boxer has been regularly visiting my practice for several months.
His main symptoms were pain from the right shoulder to the upper arm and a feeling of “catching” during movements.
Boxing and Shoulder/Arm Strain
Boxing is a sport that heavily stresses the arms and shoulders.
Not only do punching motions require snap and power, but maintaining a guard and avoiding the opponent’s attacks also heavily involve the muscles around the shoulder blades and upper arms.
Continuous training and matches can cause muscles to tense and stiffen, reducing the range of motion in the shoulder joint.
This often leads to pain and a sensation of catching or restriction during movement.
Treatment Approach for Patients Who Are Sensitive to Needles
This patient was hesitant about acupuncture, so I focused on massage and shiatsu:
Loosening the muscles around the upper arm and shoulder blade:
Tight muscles were carefully relaxed using massage and scraping tools to promote blood flow, improve flexibility, and allow smoother shoulder movement.
Deep muscle release with shiatsu:
After relaxing the surface muscles, shiatsu was applied to reach the deeper layers. By improving the movement of the shoulder blades, stress on the shoulder joint was reduced, helping restore natural punching motion.
Results After Treatment
After the session, the patient’s shoulder range of motion improved, and the catching sensation during movements was reduced.
By continuing weekly sessions, by the fifth treatment the patient reported that the catching was almost completely gone.
The Importance of Early Care for Sports Injuries
In sports like boxing, continuing to train through pain can lead to muscle stiffness, restricted motion, and increased strain on other body parts.
Limited shoulder mobility can also reduce punching speed and power.
Therefore, early care when discomfort or pain occurs is crucial.
Regular maintenance helps maintain performance during training and competitions.
Summary
Shoulder and upper arm pain from boxing is often caused by muscle tension and limited range of motion
Even patients who are hesitant about acupuncture can benefit from massage and shiatsu
Early care and regular maintenance can prevent sports injuries and improve performance
