Silencing the Phantom: Sustained Resolution of Phantom Limb Pain After an Extreme Sensory Event.

Abstract

Phantom limb pain (PLP) is a common, debilitating complication following limb amputation. Despite various available pharmacological and non-pharmacology treatment modalities, phantom limb pain can be quite challenging to treat. This clinical vignette describes the case of a man in his mid-20s with chronic PLP and history of congenital bilateral clubfoot deformity and left transtibial amputation who discharged a 12-gauge shotgun through his prosthetic boot to relieve himself of PLP. Following this unorthodox, self-directed, behavioral event involving a single intense episode of multisensory input directed at the perceived location of phantom pain, he experienced sustained resolution of his PLP. While we do not condone this behavior due to safety concerns, this unusual case highlights the potent role of sensory, cognitive, and behavioral modulation in PLP. This suggests potential applications of AI-assisted virtual or simulated sensory environments in safely engaging neural mechanisms, including sensorimotor integration and perceived control, to address this type of pain.
