Abstract: This invention relates to elbow crutches and provides a crutch to enable a patient with leg disability to raise himself from a sitting position to a standing position. Basically the invention consists in an elbow crutch, the length of which is adjustable under the control of a manually operable lever. In particular, the crutch comprises two telescopically arranged tubular members and a spring urging one tubular member outwardly with respect to the other.
