ABSTRACT:
A back support cushion which provides neurosensory proprioceptive kinesthetics cues to the thoracic region of the spine in proximity to the apex of the thoracic curve of the spine and provides support in the vertical plane. The kinesthetic cues and vertical plane support is accomplished by shaping the face of a back cushion in such a manner that a relatively firm raised mound is formed in proximity to the area of the apex of the thoracic spine. Thus, when the person is seated, the firm raised mound provides a light pressure on the area of the thoracic spine's bony and soft tissue elements--which stimulates the neurosensory end organs located in the muscles, tendons, ligaments, joint capsules and periosteum of the thoracic spine.
