Abstract
Restless legs syndrome (RLS) is a neurological disorder characterized by an irresistible urge to move the legs, frequently accompanied by unplea-sant sensations. In this study, we aimed todetermine the changes in electrophysiologi-cal tests including F-wave responses and H-reflex parameters in patients with idiopathic RLS after pramipexole medication. This prospective study was con-ducted with twenty newly diagnosed, idiopathic RLS patients. The electrophysiological parameters, specifically F-wave duration (FWD), the duration of related compound muscle action potential (CMAPD), and FWD/CMAPD ratio, the ratio of maximum H-reflex amplitude(H) to maximum M-response amplitude (M)(H/M) were recorded in patients with idiopathic RLS before and after pramipexole medication. The results revealed significant improvements in specific electrophysio-lo-gical parameters after pramipexole use. We observed a significant decrease in FWD,CMAPD, and FWD/CMAPD values after pra-mipexole treatment suggesting a reduction in motor neuron excitability. We also ob-ser-ved a significant decrease in H/M ratio after pramipexole medication indicating reduced spinal motor neuron excitability. This study demonstrated significant improvement in specific electrophysiological parameters following pramipexole treatment in patients with idiopathic RLS. The findings provide better understanding of the effects of pramipexole on nerve function and may contribute to the development of a monitoring tool and lead to more targeted treatments and interventions for RLS, improving the overall management and care for patients' outcomes and quality of life with this debilitating condition.
