ABSTRACT OF THE DISCLOSURE A continuously length adjustable crutch is provided herein. It includes (a) upper and lower telescoping tube members; (b) a handle attached to the upper telescopic member; and (c) a manually operable, self-contained energy accumulator, comprising: (1) a piston/cylinder assembly, having a piston rod attached within one of the telescopic members, a cylinder attached within the other of the telescoping members, the piston dividing the cylinder into two chambers; (2) an operating pressure fluid in the cylinder; (3) a conduit connecting the chambers, being normally closed and locking the relative position of the telescoping members; and (4) manually operable control means for opening and closing the conduit, the fluid tend- ing to expel the piston from the cylinder when the conduit is open. This crutch can be continuously length adjusted during use in the following way. An individual leaning on the crutch can be gently lowered by opening the conduit, energy being accumulated by compression of the fluid by the piston, and stored by closing the conduit after the lowering, and subse- quently, can utilize the stored energy for rising, by reopening the conduit and permitting the fluid to expel the piston and thereby to lengthen the crutch.
