Previous studies have shown the C1 spinal nerve has sensory neurons. Direct stimulation of the C1 spinal nerve provokes peri-orbital pain in migraine patients. No data exist which can predict a positive outcome for C1 nerve root block. Tenderness over the greater occipital nerve has been shown to predict outcome of GON block. We propose that tenderness over the GON with periorbital referral on exam predicts periorbital referral on direct C1 stimulation and predicts a positive outcome of block.
