The woman is otherwise healthy, takes no medication, and has no known drug allergies. The physician decides on a nonsteroidal anti- inflammatory drug that has a high affinity for cyclooxygenase-2 (COX-2) and no affinity for COX-1. Compared to other NSAIDs, this drug is less likely to cause:

Physical examination reveals relatively normal lumbar range of motion, normal straight leg raise, and reveals normal muscle tone, strength and sensation throughout both lower extremities.
