Abstract: A system comprising a combination of orthopedic traction devices for limiting abduction of the arm and preventing impingement of the user's shoulder. The devices include a nighttime ipsilateral shoulder traction device with removable leg and wrist cuffs, an elastic connecting strap connecting the cuffs to apply impingement-reducing traction to the shoulder joint; and a daytime centrifugal exercise device with a weighted member rotated by a handle using the ipsilateral arm. The invention also includes a method for using the two devices in combination, and a series of exercises for the centrifugal exercise device that specifically complement the nighttime impingement reduction of the traction device. In the preferred form, the traction device includes removable leg and wrist cuffs secured to the lower leg and wrist, respectively, and a one-handed quick release mechanism that allows the user to release the cuffed arm with the cuffed hand.
