Abstract: An arm support assembly includes an armrest and connecting assembly. The armrest may meet regulatory or industry standards and is maneuverable into a variety of positions, including seated, blood pressure reading, supping or lying, and stowed or patient transfer positions. The armrest may be padded and/or upholstered. The connecting assembly includes first and second joints each selectively rotatable and an elongate member connecting them. The first joint rotatably mounts to the armrest, and the second joint mounts to the side of an examination device such as a table or chair. The joints include a rotary mechanism to engage between locked and unlocked positions, where rotational motion is enabled in unlocked positions. Rotation at first and second joints collectively result in maneuvering the armrest between the various positions.
