If you are under the age of 40 and play a sport that requires one sided activity, such as tennis and throwing a ball you have a good chance of injury to one of the rotator cuff muscles called the subscapularis. It’s the most common shoulder injury for active people under the age of 40.
The subscapularis muscle helps you open a jar, hug someone, lift things, clap your hands and complete the forehand and serving actions in tennis. It’s the most common rotator cuff to be injured, however it is the strongest of all 4 rotator cuffs muscles.
How do you know if you have a subscapularis injury or rotator cuff injury?
Pain is often felt at the back of the arm and not in front of the shoulder due to the referred pain pattern for the subscapularis.
Also, when you laterally rotate your arm with your elbow bent at 90 degrees, i.e. the motion of a forehand swing in tennis. This motion will be painful to execute.
What to do for treatment?
1. REST!
2. Seek a massage therapist who can accurately determine you have a subscapularis injury. Most therapist who are trained in sports massage, orthopedic massage and/or Neuro-muscular therapy can do this assessment test for you. He or she will take you through the range of motion test, palpate and help you gently stretch the subscapularis to specifically locate the injury.
3. Be prepared to block your schedule for several treatment sessions for a 6 week period of treatments. The number of sessions will depend on the severity of the injury. Two per week is optimum.
4. Slowing getting back into your active routine after completion of all treatment sessions and when pain is gone and range of motion is restored.
Why? Subscapularis is the strongest muscle of the rotator cuff group and is also “submerged” against the underside of the scapula (shoulder blade). Home care between sessions is the key to a quick recovery.
