Since the surgery, Sam has very little muscle tone in his rear legs. If he does regain feeling in the legs, he would not be able to move them much or support himself because of the muscle weakness. Being able to float in the warm water of the pool is beneficial in many ways. It allows him to be supported in a weightless environment. It promotes the use of the legs with less effort. It allows him to relax his other muscles.
