ClinicalTrials.gov Identifier:
NCT01112774
First received: April 20, 2010
Last updated: April 14, 2014
Last verified: April 2014
  Purpose

The purpose of this study is to determine whether the novel treatment of transcranial direct current stimulation (tDCS) could decrease the pain perception of those with spinal cord injury.

We will also determine whether these changes are correlated with the clinical outcome (pain reduction).

Study Start Date: April 2010
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: tDCS/Spinal cord injury
Subjects will be randomized to receive 10 sessions of either active or sham tDCS. Stimulation will be given on consecutive days (Monday- Friday) at 2 mA over the primary motor cortex area.
Device: Transcranial direct current stimulation
Stimulation will be applied at 2 mA for a total of 20 minutes.
Other Name: electrical stimulation, tDCS
Experimental: tDCS/Healthy subjects
Subjects will receive 2 sessions of stimulation: one active and one sham tDCS on two separate visits. The order in which they receive the stimulation will be randomized. Stimulation parameters will be at 2 mA for a total of 20 minutes.
Device: Transcranial direct current stimulation
Stimulation will be applied at 2 mA for a total of 20 minutes.
Other Name: electrical stimulation, tDCS

Detailed Description:

The active tDCS stimulation sessions will be compared to sham stimulation.

More study details will be provided by Spaulding Rehabilitation Hospital.
