Abstract
Abstract The device of the invention for exercising the leg and arm musculature of a person lying in a bed consists of a bellows (2) which with one of its ends is adapted to be attached to for instance a bedstead end in a manner by which it is tiltable about a horizontal axis and lockable in a desired position of tilt and which at the other end thereof carries a foot or hand attachment member (3) to which the foot or hand may be attached to permit the person lying in the bed to both compress and extend the bellows. The resistance of the bellows to the said movements are controllable as desired by means of a valving device (11).
