Three local doctors have donated a much needed underwater treadmill to the Seawolves of Stony Brook University. Faculty, donors and athletes praise the addition. Hydrotherapy treadmills are known for getting student athletes rehabilitated quickly with limited interruption to school and training. Underwater treadmills help athletes perform cardiatric exercises that are intended to strengthen lower extremities without risking re injury. They also decrease the likelihood that a vigorous rehabilitation routine will lead to a new injury.
