Fluid flow in the fascia & how it is affected by treatment & vibrations
It has been found that in the connective tissue there are six times more neurons than in for example muscles. There are neurons for both pain reception and position determination. These neurons are affected by vibrations and varied movement. (1)
Recently, a German researcher showed that the connective tissue in a human transports 15 l of water in 48 hours, which is a relatively large amount compared to for example the amount of blood and the lymphatic system. (2)
There are several studies showing that manual therapy largely involves the movement of water in tissue. In many trials, it has been shown that in manual therapy it is not about tissue processing, but about increasing the flow of water in the tissue. (3, 4). The same report shows that by using static vibration we can increase the flow of fluid in the tissue from 3-12 times depending on the frequency.
