Pfrimmmer Deep Muscle massage is considered therapy one of the early forms of deep muscle massage. It was developed in the 1940s by Therese Pfrimmer, a student at the Swedish Institute in New York. Her amazing discovery, which led to the reversal of her own paralysis, utilized strong strokes across the muscle fiber rather than along the length of the fibers. This method frees up adhesions, increases circulation, of both the lymphatic and vascular systems, and forms corrective changes in the muscle on a cellular level. While working to adjust and prevent serious muscular conditions, it also relieves sports injuries, trauma, tension, and stress.
