Synchronous pattern distinguishes resting tremor associated with essential tremor from rest tremor of Parkinson’s disease

Abstract Rest tremor associated with essential tremor (ET) is a condition that poses challenges in diagnosing Parkinson’s disease (PD). We investigated tremor parameters in PD and ET patients with rest tremor. Fifteen patients with PD and 15 patients with ET underwent electrophysiological examinatio...

Zusammenfassung:	Abstract Rest tremor associated with essential tremor (ET) is a condition that poses challenges in diagnosing Parkinson’s disease (PD). We investigated tremor parameters in PD and ET patients with rest tremor. Fifteen patients with PD and 15 patients with ET underwent electrophysiological examination to evaluate characteristics of muscle bursting in rest postures. Rest tremor amplitude of PD patients was significantly higher than that of patients with ET ( p = 0.002), whereas burst duration and frequency were significantly higher in ET than in PD group ( p = 0.002, p
