Spinal cord stimulator effects on restless legs

The Effect of Spinal Cord Stimulators on Restless Leg Syndrome

Not applicable Interventional University of Alabama at Birmingham · NCT07179406

This study will test whether changing spinal cord stimulator settings alters nerve signals and improves symptoms in people with restless leg syndrome and in some people with chronic pain.

What this trial studies

This single-center interventional study at the University of Alabama at Birmingham will enroll people with RLS across four groups: RLS patients without stimulators (and healthy controls), RLS patients with existing spinal cord stimulators (SCS), RLS patients scheduled to receive an SCS, and chronic pain patients with SCS but no RLS diagnosis. Participants undergo neurophysiological testing including EEG, EMG, H-reflex, somatosensory evoked potentials (SSEP), event-related potentials (ERP), and transcranial magnetic stimulation (TMS) while SCS settings are varied. The protocol compares baseline and SCS-modulated measures to document changes in nervous-system signals and related symptom reports. Data aim to link objective electrophysiology with any symptom changes across groups.

Who should consider this trial

Good fit: Ideal candidates are adults diagnosed with restless leg syndrome who can attend UAB visits, have had no major changes in RLS medications for at least four weeks, and can provide informed consent; healthy controls and chronic pain patients with SCS are included in specific arms.

Not a fit: People without RLS or those with major exclusions such as spinal cord injury, severe peripheral neuropathy or radiculopathy, severe psychiatric or cognitive disorders, current use of another RLS device, pregnancy, or inability to comply with study visits are unlikely to benefit or may be excluded.

Why it matters

Potential benefit: If successful, the study could identify SCS settings that reduce RLS symptoms and support broader use of spinal cord stimulation as a treatment option for some patients.

How similar studies have performed: Small studies and case reports have suggested SCS can help RLS symptoms in some patients, but robust controlled data are limited.
