Abstract: A foot-pressure massage stand and method effectively massages parts of a patient's body by using foot pressure either directly upon the patient by an operator or indirectly when a patient massages himself. The foot-pressure massage stand makes it possible for an operator and a patient or a patient alone to select an appropriate width between the friction wall and the reaction wall. One disclosed method is for the patient to massage himself while sitting on the floor plate, by using various auxiliary tools to massage areas of his or her body such as the back and lateral chests. Another method involves an operator applying foot pressure to a patient permitting the force to be increased by a magnitude of ten. By exerting foot pressure using the massage stand, stronger foot pressure can be achieved than by just using body weight or by leaning against only one wall, thereby achieving a more effective massage than is possible with conventional methods.
