2023年7月24日 · In other words, a lesion at C5 would cause hyporeflexia in the biceps reflex (C5-C6) but could produce hyperreflexia in the triceps reflex. This is because the lesion is above the spinal segments (C7-C8) that contribute to the lower motor neuron reflex arc but would affect the upper motor neuron modulation (which are generally inhibitory ...

The most important upper extremity reflexes are the biceps tendon reflex for levels C5, C6 and the triceps tendon reflex for level C7. You can grade the reflex according to a commonly used 5 grade scale: 0= no response, which is always abnormal. 1+= slight but definitely present response, which may or may not be normal
