What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Transcranial Magnetic Stimulation (TMS)Device
| Study group | Role | What they receive |
|---|---|---|
| TMS Intervention for 5 days | Experimental | Application of Transcranial Magnetic Stimulation (TMS) for up to 5 days Receives: Device: Transcranial Magnetic Stimulation (TMS) |
| TMS Intervention for 1 day | Experimental | Application of Transcranial Magnetic Stimulation (TMS) for 1 day Receives: Device: Transcranial Magnetic Stimulation (TMS) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Present Pain Intensity
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.
Measured: Baseline, post-treatment, one week follow-up

Questions about this trial
What is this clinical trial studying?
A study testing Transcranial Magnetic Stimulation (TMS) in people with Complex Regional Pain Syndrome (CRPS), run by Stanford University at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 May 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 15 May 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Present Pain Intensity (time frame: Baseline, post-treatment, one week follow-up). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2017.
