The most commonly offered and best known type of massage. Devised at the University of Stockholm in 1812 by Henri Peter Ling, this technique employs five different movements (long strokes; kneading of individual muscles; percussive, tapping movement; rolling of the fingers; and vibration) and oils beneficial to the skin. Used to improve the circulation, ease muscle aches and tension, improve flexibility and create relaxation. Swedish massage is done with the person covered by a sheet, where each part of the body to be worked on is exposed in turn and then re-covered. The massage practitioners use kneading, stroking, friction, tapping and even shaking motions. Oil is used to reduce or eliminate friction and to facilitate making long, smooth, kneading stokes over the tissue and muscles of the body.
