Clinical Trial Summary

The aim of the current study is to assess the efficacy of TMS in the treatment of Complex Regional Pain Syndrome (CRPS). It is hypothesized that participants who receive TMS (Group 1) relative to sham treatment (Group 2) once daily for two days will demonstrate a greater improvement in CRPS-related pain and other associated symptomology (i.e., cognitive, emotional and physical) compared to baseline. Participants will be followed until they reach their baseline for two consecutive weeks to assess safety and duration of symptom alleviation.
