What this trial studies

This study aims to gather real-world data on the effectiveness and safety of implantable neurostimulation systems for treating chronic pain in Spain. It will involve multiple hospitals across the country, where patients will be recruited prior to their procedures. Participants will provide demographic information and will be followed up at six and twelve months post-implantation to assess outcomes. The study seeks to fill the gap in knowledge regarding these therapies in a real-world setting.

Who should consider this trial

Good fit: Ideal candidates include patients suffering from chronic refractory pain who are considering implantable neurostimulation systems.

Not a fit: Patients who may not benefit include those unable to complete follow-up or who do not understand the Spanish language.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the effectiveness of neurostimulation therapies for chronic pain, potentially improving treatment options for patients.

How similar studies have performed: While there is limited real-world data specific to Spain, similar studies in other regions have shown promising results for neurostimulation therapies in chronic pain management.
