 Deep brain stimulation DBS is an effective surgical therapy for medication-refractory symptoms of Parkinsons disease, tremor, and dystonia. Patients implanted with DBS experience a significant improvement of their symptoms with relatively low risk of intolerable side effects. Implanted patients must undergo repeat surgeries to replace the Implantable Pulse Generatorsbatteries IPG approximately every 2 to 5 years. The DBS program at the University of Florida has studied battery consumption and has been interested in potential strategies to extend the life of the IPG to reduce the need for frequent battery replacement surgeries, while improving symptom-relief, patient satisfaction, and the potential associated financial burdens.
