Treating the Infraspinatus Muscle
Muscle Energy Stretching Technique - Infraspinatus
The infraspinatus muscle is member of the rotator cuff group, which comprises the supraspinatus, infraspinatus, teres minor, and subscapularis
The rotator cuff helps hold the head of the humerus in contact with the glenoid cavity (fossa, socket) of the scapula during movements of the shoulder, thus helping to prevent dislocation of the joint.
Infraspinous fossa of scapula.
Middle facet on greater tubercle of humerus. Capsule of shoulder joint.
As a rotator cuff muscle, helps prevent posterior dislocation of shoulder joint. Laterally rotates humerus.
Antagonists: subscapularis, pectoralis major, latissimus dorsi.
Suprascapular nerve, C(4), 5, 6, from upper trunk of brachial plexus.
BASIC FUNCTIONAL MOVEMENT
Example: brushing hair back.
REFERRED PAIN PATTERNS
Middle/upper cervical spine: deep anterior shoulder joint zone of
3–4 cm in region of long head of biceps brachii, radiating into biceps belly then into forearm—diffuse symptoms in median nerve distribution.
Medial/scapula: to medial border of scapula.
Decreased range of motion in Apley scratch test (behind back), hemiplegia, rotator cuff tendinopathy, frozen shoulder syndrome, pain in back and front of shoulder, night-time shoulder pain when sleeping on same/ opposite side, dead-arm sensations, pain undoing bra, shoulder girdle fatigue, weakness of grip, loss of arm strength, changes in sweating (usually increased), “mouse arm” from computer mouse overuse.
Overuse activities with arm unsupported (e.g. computer mouse, driving, tennis, weight training, water sports, ski poles), pulling objects behind body, sudden trauma from fall on outstretched arm/ catching yourself when trying to stop a fall, prolonged holding of heavy objects.
Biceps tendonitis. C5–C6 neuropathy. Suprascapular nerve dysfunction.
Infraspinatus, subscapularis, levator scapulae, pectoralis minor/major, long head biceps brachii, biceps brachii, anterior deltoid, teres major, latissimus dorsi, rotator cuff issues, biceps tendonitis.

Scraping, a manual, ancient practice where pain points are worked with a gua sha (smooth-edged tool), reportedly increases blood flow by up to 400 per cent more than foam rolling and massage guns. By breaking up old, damaged blood vessels to promote new growth and healing, these tools are useful for getting into the nooks and crannies of a pain point, especially in delicate areas like along the shin muscles and under the foot.
Tim Tian has taken the scraper idea and supercharged it, creating a manual, triangular tool that blends heat and vibration therapy. “Cold blades stiffen muscles, blocking a deep release,” he says.
The heated scraper device takes just three seconds to reach 50ºC. This helps muscles soften, making it easier to massage away tension, increase blood flow and promote healing. The scraper is specially great for alleviating delayed onset muscle soreness (DOMS) in the quads, and provides a relaxing switch-up from the foam roller slog.
