Ultrasound-Guided Proximal Superior Cluneal Nerve Block for SCNE

Is this trial a fit for you?

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

What this trial studies

This prospective observational cohort study will enroll adults with clinically diagnosed superior cluneal nerve entrapment who undergo ultrasound-guided proximal superior cluneal nerve block as part of routine care. Researchers will measure pain intensity, disability, and neuropathic pain features at baseline, 1 month, and 3 months after the procedure using validated outcomes. The primary goal is to see how pain changes after the nerve block; secondary goals include changes in disability and neuropathic pain characteristics. The study aims to provide prospective data on the clinical outcomes of this technique when used in real-world practice. Eligibility includes adults 18-75 with chronic low back/gluteal pain and a positive response to a diagnostic SCN block.
