Does ReBuilder Help To Treat Neuropathy Pain?

Hello my dad has bilateral ulnar neurophaty. He had a surgery on july 2008 for a spondylogenic compression of cervical spinal cord C76 C65 C45. He is insuline dependent because of his diabetis. He is controlled. He takes 2.400 gr of neurontin every day. My question is if the rebuilder medical could help him calm his neurophaty pain?
