Abstract
The purpose of this study was to assess efficacy and safety of a new patterned theta burst stimulation algorithm of DBS with the aim of expanding the therapeutic window and clinical benefit in PD. In this single-center, randomized, double-blind, clinical short-term trial, unilateral conventional subthalamic DBS was compared with unilateral patterned stimulation algorithms with intraburst high- or low-frequency theta burst stimulation in 17 PD patients. There were no serious adverse events with theta burst stimulation. During monopolar review, conventional subthalamic DBS and high-frequency theta burst stimulation were comparable, but low-frequency theta burst stimulation differed by requiring higher stimulation amplitudes for symptom reduction, but a larger therapeutic window. High- and low-frequency theta burst stimulation with adapted stimulation amplitude were effective in PD symptom reduction with differential effects on akinesia and tremor, depending on the theta burst stimulation mode. Theta burst stimulation is a safe and effective stimulation mode with potential future application opportunities. © 2020 International Parkinson and Movement Disorder Society.
