The most widely recognized and commonly used category of massage is the Swedish massage. The Swedish massage techniques vary from light to vigorous. Swedish massage uses five styles of strokes. The five basic strokes are effleurage (sliding or gliding), petrissage (kneading), tapotement (rhythmic tapping), friction (cross fiber or with the fibers) and vibration/shaking. Swedish massage has shown to be helpful in reducing pain, joint stiffness, and improving function in patients with osteoarthritis of the knee over a period of eight weeks.
