Shiatsu means finger pressure in Japanese, and consists of finger and palm pressure, stretching, and compression to improve energy flow, blood circulation, flexibility, and posture. The Eastern medicine philosophy says that the main cause of disease is due to unbalanced Ki (life force) in the body. Treatment is focused along specific meridians to unblock and stimulate the flow of energy, and to harmonize Ki. Shiatsu is used to treat pain, induce relaxation, restore balance, and to maintain general health. Shiatsu is performed without oil on a mat, with the client in loose clothing.
