A system for aiding the crawling mobility of children or young adults is disclosed. The system consists of central hub supported by four legs. The patient is enclosed in a harness which is coupled to a support cord extending through the central hub. A lifting force partially offsetting the patients weight is supplied by tension on the support cord, which is locked relative to the central hub via a locking device. Coupling between the support cord and harness is provided by carabineers which are clipped to “D” rings on the harness. The balance point can be adjusted by moving the attachment point to various “D” ring locations.
