摘要：
A hydraulically adjustable walker including a frame that includes a plurality of telescoping legs and a leg adjustment assembly that includes at least one valve and at least one tube that delivers hydraulic fluid into the legs and allows a user to control the length of each leg. The legs of the walker are hydraulically adjustable, so that the front legs may be shortened and the back legs extended, or two side legs shortened and the two opposing side legs extended, so as to allow the walker to be securely placed on two different steps.
