Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 to 65 who meet the Budapest criteria for CRPS type I and are within 0 to 6 months of symptom onset.

Probably not a fit

Patients with CRPS type II, those with multiple affected limbs, or individuals who have had a recurrence of CRPS type I may not benefit from this study.

What this trial studies

This study investigates the effectiveness of non-invasive neuromodulation combined with conventional care for patients suffering from Type I Complex Regional Pain Syndrome (CRPS). It is a randomized, triple-blind clinical trial involving 42 participants who will be divided into control and experimental groups. The study aims to assess pain relief and functional improvement at three different time points: before, during, and after the intervention. Statistical analyses will be conducted to evaluate the outcomes and determine the significance of the findings.

Why it matters

Potential benefit: If successful, this treatment could provide significant pain relief and improved function for patients with Type I CRPS.

How similar studies have gone: While there is ongoing research in neuromodulation for pain management, this specific approach for Type I CRPS is relatively novel and has not been extensively tested.
