Evaluating the impact of early nerve blocks and rehabilitation on Complex Regional Pain Syndrome Type 1

Evaluation of the Relationship Between the Duration of the Evolution of the Complex Regional Pain Syndrome Type 1 (CRPS 1) and Effectiveness of the Continuous Peripheral Nerve Block (CPNB) Associated With an Intensive Rehabilitation Program

Not applicable Interventional Pôle Saint Hélier · NCT04767646

This study is testing if starting nerve blocks earlier, along with a rehab program, can help people with Complex Regional Pain Syndrome Type 1 recover better.

What this trial studies

This study investigates how the duration of Complex Regional Pain Syndrome Type 1 (CRPS 1) affects the effectiveness of continuous peripheral nerve blocks (CPNB) combined with an intensive rehabilitation program. The main hypothesis is that earlier intervention with CPNB will lead to better recovery outcomes, as measured by a scale of achievement of therapeutic objectives. Participants will receive CPNB and engage in a structured rehabilitation program to assess improvements in their condition. The study aims to refine therapeutic strategies for managing CRPS 1.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with CRPS Type 1 who are experiencing severe pain and have not responded to other treatments.

Not a fit: Patients with CRPS Type 2 or those who have contraindications to the analgesics used will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance recovery outcomes for patients suffering from CRPS Type 1.

How similar studies have performed: While there is ongoing research in pain management for CRPS, this specific approach combining CPNB with intensive rehabilitation is relatively novel.
