Stellate Ganglion Stimulation for Restless Leg Syndrome in Hemodialysis Patients

This randomized controlled trial investigated the effect of transcutaneous stellate ganglion electrical nerve stimulation (TENS-SG) on restless legs syndrome (RLS) in patients undergoing hemodialysis. Thirty-six patients aged 40-50 years were randomly assigned to two equal groups: Group A received active TENS-SG applied over the cervical-thoracic (stellate ganglion) region three times weekly for four weeks, while Group B received placebo stimulation. The study evaluated multiple outcomes including RLS severity (IRLS scale), sleep quality (PSQI), quality of life (SF-12), pain perception (pressure pain threshold), blood pressure, psychological status (HADS), and plasma β-endorphin levels. Results demonstrated that TENS-SG significantly reduced RLS severity and improved sleep quality, pain threshold, quality of life, and psychological well-being compared to placebo. It also significantly reduced systolic and diastolic blood pressure and markedly increased β-endorphin levels. Overall, the findings suggest that TENS-SG is a safe, non-invasive, and effective intervention for improving neurological, cardiovascular, psychological, and quality-of-life outcomes in hemodialysis patients with RLS.
