A 4-year-old boy with a history of autism presents to his pediatrician’s office with a complaint of right leg pain. He is presumed to have pulled a muscle; an elastic bandage is applied and he is given ibuprofen. Over the next few days, he begins falling and tripping and is unable to maintain his balance. At a return visit, the patient’s mother says her son’s right leg is “like Jell-O” and that he appears to be dragging the leg.
