Shoulder injury? Check this muscle first.

In today’s muscle of the day we have a very important muscle that is part of the group called the rotator cuff.   This muscle is the infraspinatus muscle.   It sits on the back part and covers the majority of the shoulder blade. This muscles is classically considered an external rotator, but it’s main job is to provide support and stability to the shoulder joint.   This muscle is very important in any pressing or pushing motion of the shoulder.   This muscle is very likely to develop adhesion from overuse. Adhesion is like glue that gets inside the muscle and keeps it from being able to stretch and contract like its supposed to.   Over time the adhesion builds up more and more, leading to the following:   Pain Weakness Decreased flexibility   When this occurs the shoulder often alters it biomechanics to help work around the dysfunction. Often this leads to more force being put on the other structures around the shoulder, especially the biceps tendon and supraspinatus muscle.   So if you have a biceps tear, surpraspinatus tear or been diagnosed with shoulder impingement you might need to have someone check the function and health of the infraspinatus muscle.   One last very important thing...   Do not jam a lacrosse ball into this muscle, all you do is crush and make it worse!

This muscle is the infraspinatus muscle.

 

It sits on the back part and covers the majority of the shoulder blade. This muscles is classically considered an external rotator, but it’s main job is to provide support and stability to the shoulder joint.

 

This muscle is very important in any pressing or pushing motion of the shoulder.

 

This muscle is very likely to develop adhesion from overuse. Adhesion is like glue that gets inside the muscle and keeps it from being able to stretch and contract like its supposed to.

 

Over time the adhesion builds up more and more, leading to the following:

 

Pain

Weakness

Decreased flexibility

 

When this occurs the shoulder often alters it biomechanics to help work around the dysfunction. Often this leads to more force being put on the other structures around the shoulder, especially the biceps tendon and supraspinatus muscle.

 

So if you have a biceps tear, surpraspinatus tear or been diagnosed with shoulder impingement you might need to have someone check the function and health of the infraspinatus muscle.

 

One last very important thing...

 

Do not jam a lacrosse ball into this muscle, all you do is crush and make it worse!
