Interesting facts about the infraspinatus muscle:
The infraspinatus is one of the most problematic muscles in the human body. It along with three other muscles that make up the rotator cuff are responsible not only for shoulder movements but also for holding the shoulder joint together. Trigger points in the infraspinatus can render the shoulder almost immobile. It is painful to raise the arm, bring the arm across in front of the body or bend the arm back behind the body. The inability to do these movements is often diagnosed as frozen shoulder.
Clinical diagnoses to which this muscle symptoms may contribute:
- Adhesive capsulitis (Frozen shoulder)
- Rotator cuff tear
- Rotator cuff tendinitis
- Brachial plexus injuries
- Thoracic outlet syndrome
- Subdeltoid bursitis
- Bicipital tendinitis
- Rheumatoid arthritis
- Cervical arthritis or spurs
- Supraspinatus tendinitis
- Shoulder pointer
- Shouder Sprain / Strain injury
Other muscles that should be considered and examined in conjunction with the infraspinatus:
Satellite Trigger Points: Teres Minor, Anterior and Posterior Deltoid, Biceps Brachii, Supraspinatus, Teres Major, Latissimus Dorsi
Affected Organ Systems: Digestive system
