Abstract: An apparatus permits a user to simulate crawling motions and provides enhanced movements of the person's truncal spinal muscles and joints. The apparatus comprises a flat base for supporting a person in position where there is minimal axial gravity loading of the spine, and hand and knee rests respectively fixed and pivoting relative to the flat base to permit relative motion between axial portions of the spine trunk, especially the upper (thoracic) and lower (pelvic) portions of the person's trunk, while the person remains in the gravity unloaded position. The base mounts a fixed rest and a pivoting or swiveling rest, the swiveling rest comprising a pair of pivoted supports which can move in circular lateral paths independent of each other.
