BackgroundAlthough recently introduced directional DBS leads provide control of the stimulation field, programing is time-consuming.ObjectivesHere, we validate local field potentials recorded from directional contacts as a predictor of the most efficient contacts for stimulation in patients with PD.MethodsIntraoperative local field potentials were recorded from directional contacts in the STN of 12 patients and beta activity compared with the results of the clinical contact review performed after 4 to 7 months.ResultsNormalized beta activity was positively correlated with the contact's clinical efficacy. The two contacts with the highest beta activity included the most efficient stimulation contact in up to 92% and that with the widest therapeutic window in 74% of cases.ConclusionLocal field potentials predict the most efficient stimulation contacts and may provide a useful tool to expedite the selection of the optimal contact for directional DBS. © 2017 The Authors.
