Introduction[edit | edit source]
A myofascial chain is a line of connective tissue that runs through out the body. There is a posterior (back) line, anterior (front) line, spiral, and lateral lines. These lines help the body to move as a unit.
Myofascial chains are important to functional movement, coordination and stability. They can be a cause of pain within the body and structural weaknesses. By understanding myofascial chains, you can better understand injuries and movement limitations.
In the upper limb there are four myofascial chains:
- Superficial front arm line
- Deep front arm line
- Superficial back arm line
- Deep back arm line
Superficial front arm line[edit | edit source]
- Medial ⅓ clavicle, coastal cartilage
- Pect maj, Latti dorsi
- Medial humeral line
- Medial IM septum
- Medial humeral epicondyle
- Flexor group
- Carpal tunnel
- Palmar surface of the fingers
Deep front arm line[edit | edit source]
- 3,4,5 ribs
- Pect minor
- Coracoid process
- Biceps brachii
- Radial tuberosity
- Radial periosteum, ant border
- Styloid process of radius
- Radial collateral ligaments, thenar muscles
- Scaphoid, trapezuim
- Outside of the thumb
Superficial back arm line[edit | edit source]
- Occipetal ridge
- Nuchal ligament
- Thoracic spinous process
- Trapezuis
- Spine of scapula, acromion, lat ⅓ clavicle
- Deltoid
- Deltoid tubercle of humerus
- Lateral IM septum
- Lat epicondyle of humerus
- Extensor group
- Dorsal surface of fingers
Deep back arm line[edit | edit source]
- Spinous process of lower cervical and upper thoracic
- Rhomboids and levator scapula
- Medial border of scapula
- Rotator cuff muscles
- Head of humerus
- Triceps trachii
- Olecranon of ulna
- Fascia along ulnar periosteum
- Styloid process of ulna
- Ulnar collateral ligaments
- Triquetrum, hamate
- Hypothenar muscles
- Outside of little finger
Stabilization Tracts[edit | edit source]
1. Back arm line[edit | edit source]
Latissimus dorsi
Thoracolumbar fascia
Sacral fascia contralateral to thoracolumbar fascia
Gluteus max contralateral to thoracolumbar fascia
Vastus lateralis
2. Front arm line[edit | edit source]
Pec major
External oblique
Adductor longus (opposite side of external oblique)
Gracilis
Pes anserine
Tibial periosteum
