Systems and methods are provided for supporting an arm of a user that includes a harness configured to be worn by the user, and an arm support coupled to the harness and including an arm rest to support an arm of the user. The arm support is configured to accommodate and follow movement of the arm without substantially interfering in such movement. The arm support may at least partially offset a gravitational force acting on the arm as the user moves and the arm support follows the movement of the users arm. For example, the arm support may transfer at least a portion of the weight of the users arm to the torso or other region of the users body and/or may apply an opposing force to at least partially offset the gravitational force acting on the arm.
