Nocturnal dorsal pain is a poorly characterized clinical complaint that may arise without evident structural pathology. In some patients, unconscious micro-movements during sleep may repeatedly activate sensitized metameric pathways, producing localized dorsal pain that appears predominantly at night. This report describes the resolution of nocturnal dorsal pain after treatment with the Grapas metamericas method, a technique based on intense cutaneous stimulation applied at specific metameric points corresponding to spinal nerve segments. The intervention aims to modulate pathological nociceptive circuits through peripheral metameric stimulation. Following the application of the staples, the patient experienced rapid disappearance of the nocturnal pain. This observation suggests that metameric cutaneous stimulation may play a role in the modulation of chronic or recurrent dorsal pain associated with segmental sensitization.
