To perform the patellar reflex test, the patient should be in a comfortable seated position with their legs hanging freely. Using a reflex hammer, the nurse should gently tap the patellar tendon located just below the kneecap. The expected response is an involuntary extension of the lower leg. A brisk reflex can indicate hyperreflexia, while a diminished or absent reflex may suggest hyporeflexia or areflexia.
