Swedish massage is a vigorous and relaxing system of treatment designed to energize the body by stimulating circulation. Five basic strokes are used to manipulate the soft tissues of the body. The disrobed client is covered by a sheet or towel, with only the area being worked on exposed. Therapists use a combination of kneading, rolling, vibrational, percussive, and tapping movements, with the application of oil, to reduce friction on the skin. The many benefits of Swedish massage may include generalized relaxation, dissolution of scar tissue adhesions, and improved circulation, which may speed healing and reduce swelling from injury.
