Transcranial Magnetic Stimulation (TMS) for CRPS

May 11, 2017 updated by: Sean Mackey, Stanford University

Transcranial Magnetic Stimulation for CRPS

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
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.
Baseline, post-treatment, one week follow-up
