DEVICE PERMITTING A USER TO SIMULATE CRAWLING MOTIONS TO IMPROVE MOVEMENT OF THE TRUNCAL MUSCLES AND SPINE

摘要

Apparatus which allows a user to simulate crawling motions while the spine is maintained in a position in which it is subjected to minimal gravity induced axial loading. The apparatus comprises a base (12) and a swiveling portion (34) to permit relative motion between axial portions of the spine trunk. The device contains a fixed portion (14) and a pivot point (36) for the swiveling portion to rotate on and about. The swiveling portion comprising a pair of pivoted supports (78) and (80) which can move in circular lateral paths independent of each other. In use the user assumes an all fours position and by kneeling or leaning on the swiveling portion (34) engages in a crawling motion alternating movements of each leg or arm, which causes the upper and lower portions of the trunk to move relative to each other. The resistance to movement can be enhanced by incorporating a sloped track structure (132a) for the swiveling portion of the device to follow. The supports for the hands (22) or knees (30) can be mounted on the base (12) in an adjustable fashion.
