Details and patient eligibility

About

The purpose of this pilot study is to test whether Transcranial Magnetic Stimulation (TMS) may alleviate the symptoms of Complex Regional Pain Syndrome (CRPS). The investigators will test various methods of TMS in a small pilot study to investigate what methods may have clinical potential. This is a small pilot study to determine feasibility and signal to potentially inform future trials.
