Therapeutic approach developed by Gerda Boyesen, a clinical psychologist and physiotherapist born in Norway. It is related to bioenergetics. One of its principles is that, when bodily fluids do not circulate efficiently or tissues are not properly cleansed, emotional tensions or blockages show up and keep bioenergy from vitalizing the body. She emphasized the links between the psyche and the physical and she used massage to remove emotional trauma from organs of the body (biodynamic massage). She claimed to detect the variations in health by monitoring the fluid sounds through her stethoscope.
