ABSTRACT:
A special configured rehabilitating quadcane implement providing major advancements in the art; including: a.) positive vertical incremental adjustment of staff height to suit user; b.) the staff is readily rotatable 180.degree., so as to facilitate both left and right hand usage; c.) during final stages of rehib-recovery the cane-staff may be extracted from the quadleged-base spider via provision of a special safety-lock turn-flap device, enabling monocane use; d.) each of the quadlegs are independently adjustable as to ground-spread, thereby accommodating different stability requirements of patients. Most of the adjustments are provided via a well known spring-tensioned button-detent indexing device, whereby detent-holes are staged at regular intervals. Moreover, the adjustable quadlegged-base enables the user to align the leading edges of the two frontal-legs, so that the cane staff rocks forward exactly inline with the direction of walking.
