Guiding deep brain stimulation contact selection using local field potentials sensed by a chronically implanted device in Parkinson's disease patients

摘要: We have found that a set of support vector machines operating upon local field potentials sensed from an implanted DBS lead can identify the contact chosen by physician for patient's STN therapy with 91% accuracy. The finding is based on small data and thus subject to change further collection cross-validation. Nevertheless, results suggest algorithm selecting effective signals may be feasible.
