A married 29-year-old woman was presented as the neurology patient at the examination of a young psychiatrist for his specialty certification in psychiatry. Four months previously she had been riding in a car, driven by her husband, that was involved in a minor traffic accident. She was thrown forward, but was kept from hitting the window or dashboard by her seat belt. Three days later she began to complain of a stiff neck and sharp pains radiating down both arms, her spine to the small of her back, and both legs. Because an orthopedic consultation failed to uncover the cause of the pain, she was referred to the neurology clinic.
