Abstract: A novel shoulder brace that can provide active dynamic support to an injured shoulder while providing the capability to also raise the attached arm and support the arm in an elevated position. The brace can be used both in conjunction with a rehabilitation intervention program to maintain or restore range of motion and strength and to assist in functional tasks at work and at home. The brace works by supporting a locking or ratchet mechanism connected to an arm cuff from a chest piece that, when desired, the user can move the arm connected to an injured shoulder and supported by the arm cuff from a normal side resting position to an elevated position 90 degrees from the resting position while transferring the load created by the arm and whatever the hand is holding back to the chest piece and to the torso of the user. A release mechanism can be used to release the locking or ratchet mechanism to let the user lower their arm back to a resting position.
