A cuff portion for a forearm crutch, and a forearm crutch incorporating such a cuff portion are described. The forearm crutch consists of a lower elongate and generally straight part, an upper elongate generally straight part connected to and in particular angled relative to the lower elongate part, a handle part for gripping by a patient for example at or about the said angle, and a cuff portion connected to the end of the upper straight part. The cuff portion is modified by provision of a stabilising arm (4, 5) connected to the cuff (2) and outwardly extendable relative to the cuff so as to be moveable between a retracted position close to the side of the cuff and an extended position outwardly from the side of the cuff so as to define in combination with the cuff a base on which the crutch can be stood in an upright position.
