The Role of Fascia in Movement and Function
 
Fascia, or connective tissue, helps muscles communicate. See how to keep this important part of your body supple to improve your mobility and decrease pain.
 
 
Fascia
  • Sheets/layers of connective tissue that envelop specific structures  (e.x., fascia, surrounds and separates the tendons and muscles of the hand) and segregate one structure/organ/area from another
  • It has equal resistance to tensile strain
  • It allows mechanotransduction in any direction
  • Fascia has an irregular collagenous weave. It contains collagen fibers that connect the skin to underlying structures as well as variable amounts of fat. Tendons, ligaments, and aponeuroses are not considered fascia
  • Fascia provides protection, support and separation of muscle groups or organs. Enhances function of muscles and skin.
  • It can contain destructive processes and prevent the spread of bleeding, infection, and tumor spread among adjacent compartments
  • Fascia assists with the production and control of motion. Fascia specializes to have postural functions in which stress bands can be demonstrated
  • Planes of fascia are important in surgery
  • two types, superficial and deep:
Superficial Facia
deep to dermis and attached to dermis, contains: connective tissue, adipose tissue, vascularized, lymph, nerves, sweat glands
 
Deep Fascia
Thin fibrous layer of dense connective tissue, surrounds muscles and other deep structures, can form intermuscular septa- important for fight against metastatic disease

Plantar Fasciitis

The plantar fascia is the thick band of connective tissue that runs from your heel to your toes and supports the muscles and arch of the foot. Plantar fasciitis is an overuse injury that occurs when this tissue is repetitively stressed – such as with new or increased activity, prolonged standing, walking, or running (especially on hard surfaces), improper footwear, or a combination of the above. Overuse in this way will eventually lead to tissue fatigue, over-stretching and micro-tearing of the plantar fascia, predominantly around the heel attachments which is what causes the pain and inflammation in this area.(2)
