As a rehabilitation implement, it would produce patient controlled effort to the shoulder musculature. It appears more functional than single plane exercises commonly seen with shoulder rehab. As a team physician for the Women's National Wheelchair Basketball team, I could see this item being a very useful part of the athletes' regular training that inevitably focuses on optimal upper limb strength. The inertial element of the weighted ends would be a great tool to help improve core control of the thoracic level paraplegics who have weak trunk control. It would help the shoulder stabilizers stay strong and effective as opposed to being overrun by the prime movers, a common path to rotator cuff injuries.
