The purpose of this pilot study is to test the durability of response to Transcranial Magnetic Stimulation (TMS) for the symptoms of Complex Regional Pain Syndrome (CRPS). The investigators will test various methods of TMS for varying lengths of time in a pilot study to investigate what the clinical impact.

Condition Intervention

Primary Outcome Measures:
  • Present Pain Intensity [ Time Frame: Baseline, post-treatment, one week follow-up ]
    Present pain intensity was reported by participants using a visual analog scale (VAS) from scores ranging from 1-10; lower scores represent less pain, higher scores represent more severe pain.

Enrollment: 20
Study Start Date: February 2014
Study Completion Date: March 2015
Primary Completion Date: February 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TMS Intervention for 5 days
Application of Transcranial Magnetic Stimulation (TMS) for up to 5 days
Device: Transcranial Magnetic Stimulation (TMS)
