Introduction[edit | edit source]
A myofascial chain is a line of connective tissue that runs throughout the body. There is a posterior (back) line, an anterior (front) line, a spiral line, and a lateral line. These lines help the body to move as a unit.[1]
Myofascial chains are important for functional movement, coordination and stability.[2] They can, however, also cause pain within the body and structural weakness.[3] By understanding myofascial chains, you can better understand injuries and movement limitations.[4]
In the upper limb there are four myofascial chains[5]:
- Superficial front arm line (Figure 1)
- Medial third of the clavicle, coastal cartilage
- Pectoralis major, Lattissimus dorsi
- Medial humeral line
- Medial intermuscular septum
- Medial humeral epicondyle
- Flexor group
- Carpal tunnel
- Palmar surface of the fingers
- Deep front arm line (Figure 2)
- 3rd, 4th and 5th ribs
- Pectoralis minor
- Coracoid process
- Biceps brachii
- Radial tuberosity
- Anterior border of radial periosteum
- Styloid process of radius
- Radial collateral ligaments and thenar muscles
- Scaphoid and trapezuim
- Outside of the thumb
- Superficial back arm line (Figure 3)
- Occipital ridge
- Nuchal ligament
- Thoracic spinous process
- Trapezius
- Spine of scapula, acromion, lateral third of clavicle
- Deltoid
- Deltoid tubercle of humerus
- Lateral intramuscular septum
- Lateral epicondyle of humerus
- Extensor group
- Dorsal surface of fingers
- Deep back arm line (Figure 4)
- Spinous process of lower cervicals and upper thoracic, C1-4 transverse processes
- Rhomboids and levator scapula
- Medial border of scapula
- Rotator cuff muscles
- Head of humerus
- Triceps brachii
- Olecranon of ulna
- Fascia along ulnar periosteum
- Styloid process of ulna
- Ulnar collateral ligaments
- Triquetrum, hamate
- Hypothenar muscles
- Outside of little finger
Stabilisation Tracts[edit | edit source]
