Is this trial a fit for you?

Likely a good fit

Adults 18 years or older with clinically and MRI-confirmed lumbosacral radiculopathy and neuropathic pain who are scheduled for TFESI.

Probably not a fit

Patients without neuropathic pain components or those not responsive to TFESI may not experience meaningful benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This prospective interventional study will enroll adults with lumbosacral radiculopathy who are scheduled to receive TFESI. Neuropathic pain severity will be measured with the Neuropathic Pain Scale before the procedure and during follow-up after TFESI to see if pain symptoms improve. Secondary assessments may include overall pain intensity and functional status to capture potential benefits on daily activities. The study aims to clarify the role of TFESI in modulating neuropathic pain components in this patient population.

Why it matters

Potential benefit: If successful, participants may experience reduced neuropathic pain and improved function after TFESI.

How similar studies have gone: Prior use of TFESI for radicular pain supports potential benefit, though specific impact on Neuropathic Pain Scale scores is less well established.
