How to test for tendon reflexes?

Doctors test tendon reflexes to determine the integrity of communication between the nerves in the extremities and the spinal cord or brainstem. A quick tap from a tendon hammer is used to test reflexes at specific sites in the body. The tap activates sensory receptors within the tendon, which sends a message stimulating a return message that causes the muscle to contract. There is no tendon reflex tested for the C4 nerve. Damage to the C5 cervical nerve can cause diminished tendon reflexes of the biceps and brachioradialis muscles. Tapping the brachioradialis tendon typically cause contraction of this muscle in the forearm, whereas tapping of the biceps tendon usually causes contraction of this muscle at the front of the arm above the elbow.
