What is C5 C6 reflex?
The biceps brachii reflex is obtained by tapping the distal tendon in the antecubital fossa. This reflex occurs at the C5-C6 level. The brachioradialis reflex is obtained by tapping the radial aspect of the wrist. It is also a C5-C6 reflex.
What is the C6 reflex?
Brachiradialis reflex: (C5-C6) Knee reflex: (L2-L4) Slightly lift up the leg under the knee, and tap the patellar tendon with a reflex hammer. There should be a reflex contraction of the quadriceps muscle (knee extension). (If performed in a sitting position, have the legs dangle over the edge of the chair or table).

What does absence of reflex indicate?
When reflex responses are absent this could be a clue that the spinal cord, nerve root, peripheral nerve, or muscle has been damaged. When reflex response is abnormal, it may be due to the disruption of the sensory (feeling) or motor (movement) nerves or both.
