Suggested Immobilization Test with heart rate variability to help diagnose restless legs

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

Participants who meet the International RLS Study Group clinical criteria and are scheduled for in-lab polysomnography will undergo a Suggested Immobilization Test while heart rate variability (HRV) is recorded for exploratory analysis. The protocol aims to capture objective physiologic signals that accompany urge-to-move symptoms and compare findings against standard clinical diagnosis. Patients with major physical limitations or pregnancy are excluded to avoid confounding or inability to complete the test. The approach seeks to distinguish true RLS from mimicking conditions by adding an objective physiologic layer to usual symptom-based diagnosis.
