US 5,211,162 A · Apparatus and method for massaging the back utilizing pneumatic cushions

Abstract

The apparatus comprises a pad and a sequential pressure device that includes a pneumatic system and a control system. The pad comprises a plurality of adjacent chambers extending transverse to the pad's longitudinal centerline and has a lower section with at least two chambers and an upper section with at least three chambers. Two adjacent chambers of the lower section have approximately the same transverse cross-sectional area for about their lengths. Each chamber of the upper section includes a right portion, a left portion and an intermediate portion which has a narrowed center portion of reduced cross-sectional area connecting with the right and left portions. Inflation of an upper section chamber causes expansion of the right, left and intermediate portions thereof with a void created about the narrowed intermediate portion. The method makes use of the apparatus to massage the back of a patient placed in a supine position on the pad to mobilize the spine and stretch and relax the musculature and soft tissue of the back while avoiding placement of undue pressure on the thoracic vertebrae portions of the spine which are positioned above the intermediate portions of the chambers of the pad upper section.
