Study Summary

This trial is testing whether electrical stimulation of the spinal cord can help control pain. Investigators will ask subjects to report the types of sensations felt and perform detailed psychophysical metrics to examine participants' ability to discriminate sensations.

Eligible Conditions
  • Amputation
  • Phantom Sensation


Screening ~ 3 weeks
Treatment ~ Varies
Follow Up ~up to 2 days
This trial's timeline: 3 weeks for screening, Varies for treatment, and up to 2 days for reporting.

Experimental Treatment
Group I: Stimulation in individuals with implanted stimulation systemsExperimental Treatment1 Intervention
During psychophysical stimulation trials, an external stimulator will be connected to the SCS lead, a volley of stimulation will be performed, and the subject will be asked to respond to standard psychophysical questions, as well as to provide any additional comments.
