The Fascia contains of many receptors, along longer paths, between the vertebrae, along the muscles and so on. These receptors read and indicate the position in which we are and how tissues are stretched. When overstretching we feel a burning sensation.
Both muscles and connective tissue can be overstretched, which especially damages the muscle fibers that are overstretched. The reaction to such an injury is usually subsequent cramping of the area around the damage. Impaired position detection is often the reason that we easily overextend and hurt ourselves in the areas previously hardened. In places where the body has become stiff and numb the nervous system cannot signal to the situation as quickly as it should- therefore controlling our movements is more difficult. This can of course be avoided by ergonomically balanced movements where we just move as fast and advanced as we feel that our body can handle. It is often under stress or carelessness that we fail to do this and harm ourselves.
Therefore, classical connective tissue massage does not work particularly well. It burns and causes pain. Vibrations that restore the Fascia’s fluid balance and mobility are far more comfortable. Especially since the look is different, from a distance closed to the pain zone.
