Scar tissue (or adhesions), is made up of collagen fibres which are laid down in response to trauma, injury, surgery, or repetitive motion.
This can occur in muscles, tendons, ligaments, fascia, joints and nerves.
The first response is heat, swelling, inflammation and pain.
After the inflammation comes repair the laying down of collagen fibres and the formation of scar tissue.
Remodeling causes the scar tissue to adhere to muscle fibres, which prevents the muscles from gliding smoothly against each other.
It adheres to connective tissue, which limits the flexibility of the muscle or joint.
When scar tissue forms around nerve cells it can lead to problems such as carpal tunnel syndrome, chronic back pain.
It can bind up many layers of muscle and connective tissue, restricting your flexibility and range of movement.
Scar tissue is less elastic than healthy tissue, creating a weakness in the muscle and re injury easily occurs. It also restricts the circulation and lymphatic drainage to the muscle, which prevents the muscle receiving oxygen and nutrients that are needed for the healing process.
It is also much more pain sensitive than healthy tissue.
Repetitive motion, such as computer over-use causes the muscles to tighten up, swelling occurs, then restriction of blood flow prevents oxygen and nutrient supply to the muscles and connective tissue. The lack of oxygen causes scar tissue to form.
To avoid the formation of adhesive scar tissue after an injury, surgery, or excessive muscle overuse, healing must take place in the presence of a full range of movement.
