This study aims to evaluate neurophysiological responses and symptom changes in individuals with Restless Legs Syndrome (RLS) and/or chronic pain. Participants will undergo standard clinical assessments including EEG, EMG, h-reflex, SSEP, ERP, and TMS under varying SCS conditions.The study involves 4 arms. Arm 1 are individuals diagnosed with RLS and Healthy Controls. Arm 2 are individuals diagnosed with RLS and have an existing SCS. Arm 3 are individuals diagnosed with RLS and scheduled to receive a SCS. Arm 4 are individuals with chronic pain and have a SCS, but no diagnosis of RLS.
