In the same manner, as the body builds scar tissue after damage to the skin, scar tissue builds up in the Fascia inside the body when it is damaged. Therefore, we can get a chronic reduction in movement inside after an operation in which the Fascia is sewn together. It will not be the same hard and jagged scar tissue when the Fascia can heal itself together without stitches.
Scarring and thickening also occur naturally in the overworked parts.
As described in Fascia’s basic composition, it can build up quickly to withstand high stress. Veterinary Dr. Vibeke Sødring Elbrønd described how she was able to find scarring and thickening in the parts of dissected horses which she already knew had injuries and lameness. The body is built on where it is overloaded, even with bone tissue where the bone is overloaded, so-called upper leg, or calcification. The same thing goes for human tissue.
People who overload a body part for a long period of time will be stiffer and will have thickened connective tissue in the most strained parts.
This can be difficult to treat and remove in a short time. Especially if the body continues to be subjected to the load. But, if the spasms stop and mobility increase the Fascia will usually follow slowly and soften. A thickened Fascia will naturally lose elasticity and mobility. The area will become more difficult to treat and the results can be slower.
When thickened, connective tissue treatment may have to be repeated several times over a longer period so that the tissue gets a chance to recover.
