Infraspinatus: one of Rotator Cuff (stabilizes head of humerus in glenoid cavity, - laterally rotates the shoulder (g/h joint), adducts the shoulder (g/h joint), Extends Shoulder (g/h joint), O = Infraspinous fossa of scapula, I= Greater tubercle of humerus

The Suprascapular Nerve runs through the suprascapular notch to supply the supraspinatus muscle. It further travels through the spinoglenoid notch to innervate the infraspinatus muscle. Damage at the suprascapular notch causes weakness in shoulder abduction and also external rotation, whereas if the nerve is compressed/damaged at the spinoglenoid notch only the infraspinatus muscle and external rotation will be affected.

The infraspinatus muscle is a thick triangular muscle, which occupies the chief part of the infraspinatous fossa (center of shoulderblade). As one of the four muscles of the rotator cuff, the main function of the infraspinatus is to externally rotate the humerus and stabilize the shoulder joint.

NAT Compression inhibition technique for Infraspinatus muscle - ICT technique - Supine. This patient is suffering a frozen shoulder. Note that the main trigger point is somewhere near the medial border. It’s a comfortable hands breadth in. Use finger tips to press but try to keep a flat wrist (to protect your wrist) and lever against the plinth/surface. For therapists who wish to learn / certify NAT techniques for complex shoulder conditions, visit…
