ABSTRACT:
The invention relates to an adjustable seat or cushion which can be used by a chiropractor to bring relief to sufferers of low back pain or sacroiliac problems. The seat cushion includes a base and a pair of side-by-side cushion portions. An adjusting mechanism is provided in one cushion portion so that the elevation of that cushion portion relative to the base can be adjusted. In this manner a differential loading can be placed on the spine of a patient, by raising one hip relative to the other, so as to relieve pressure in the vertebrae and thereby reduce pain.
