Cupping therapy is primarily used for musculo-skeletal disorders like sprains, strains, muscle spasms, etc. A vacuum is created by drawing air out of the cups while it is on the skin creating a suction effect. This action draws the skin upward into the cup helping to relieve congestion of blood and energy in the area where it is placed.
Guasha (gwa-sha) is a form of therapy which employs dermal friction and pressure to help relieve primarily musculo-skeletal disorders. A lubricant is placed on the skin. The guasha tool is run over the treatment area. It is very useful for tight muscles in the back. People often will feel a difference when they get off the treatment table.
Shiatsu (she-at-su) is a Japanese word meaning "finger pressure". Pressure is applied to acupuncture points and their associated meridians. The same principles of strategically using acupuncture points to address underlying problems applies. Tuina (twee-nah) is Chinese massage. It uses different stroke techniques and manual styles to help relieve pain, tension and restore balance to the muscle meridians.
