Management of nonpainful supernumerary phantom limbs after incomplete spinal cord injury with visual-tactile feedback therapy: a case report.

SPL after SCI is poorly characterized, usually occurring within 6-7 days of injury after a complete or incomplete cervical SCI. While the mechanism is unclear, the inability to integrate visual, tactile, and proprioceptive information after deafferentation may contribute to development. Similarities between SPL and phantom limb sensation after an amputation have resulted in the use of visual and visual-tactile feedback therapy for painful SPL management. This is the first case documenting successful use of visual-tactile feedback therapy to manage nonpainful SPL.
