A forearm walking crutch includes an upper part mounted on a stick. The upper part carries a forearm sleeve and includes a grip. The sleeve is adapted to embrace the forearm of a user by more than 270° and is pivotably attached to the upper part. The upper part includes an upper piece and a lower piece, with the upper piece being adjustable relative to a lower piece. A device is provided to fix the upper and lower pieces against relative movement. The sleeve is pivotal between a first position which covers the device and a second position which exposes the device.
