Abstract
A height adjustable crutch includes a single tube member, a foot grip, an underarm support, and a handle. The single tube member has a central axis along which a main member, a telescoping top member, and a telescoping foot member are aligned. The top member is adjustable relative to a top end of the main member. The foot member is adjustable relative to bottom end of the main member. The foot grip is fixedly attached to the foot member, and the underarm support is fixedly attached to a top end of the top member. The underarm support is generally perpendicular to the central axis of the single tube member. The handle is fixedly attached to the main member and is offset from the central axis of the single tube such that a gap separates a central area of the handle and the main member.
