Thai massage tools are typically used to apply pressure to certain areas in order to improve circulation, reduce tension and increase relaxation. The T-shaped tool is used to apply pressure to the back, shoulders, neck and feet, while the wood star can be used to massage the face and scalp. The stick-like tool is used to massage the arms, legs and joints, while the knobby tool can be used to work on pressure points in the feet. Generally, the tools are used in a circular, kneading motion. To get the most out of the massage, it is best to have a professional demonstrate the proper technique.
