This technique utilizes deep cross-fiber strokes applied with the thumbs and fingers. Developed by Therese Pfrimmer of Canada, this is a deep muscle therapeutic technique. The technique was discovered in an effort to help herself recover from paralysis. The work enables free flow of lymph and blood, as well as improving joint movement and removal of waste products/toxins from the muscle tissue. Conditions that benefit from Pfrimmer Deep Tissue Massage include arthritis, multiple sclerosis, headache, and fibrositis, among others.
