Official title
Transcranial Magnetic Stimulation (TMS) for Complex Regional Pain Syndrome (CRPS)
Overview
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.
Interventions
- Device Transcranial Magnetic Stimulation (TMS)
The Magventure TMS stimulator will be used to perform intermittent theta burst followed by high frequency Transcranial Magnetic Stimulation (TMS).
Primary outcome measures
- Change in Pain [Time frame: 1 week follow-up compared to baseline]
- Duration of Pain Relief [Time frame: Duration from last treatment until pain returns - up to an estimate of 6 months]
Secondary outcome measures (1)
- Change in Pain-related Symptomology [Time frame: Duration from last treatment until pain returns - up to an estimate of 6 months]
