Hello, My father is 72 years old and had a tumor growing inside his spinal column which had dimished the spinal flow fluid and limiting the use of his legs. About 2 years ago, he had back surgery and successfully removed the tumor. We were told the back survery was a success, however he was not succssful completing the rehab and has not walked since the surgery. The muscles in his left leg have atrophied and the achilles tendon has shrunk to the point that he can not place his foot on the ground flat. We are wondering what are options are at this point. Is there a procedure to get the achilles tendon to stretch and allow him to resume rehab?
