Abstract

Abstract: Deep brain stimulation (DBS) is a neurosurgical technique that consists of continuous delivery of electrical pulses through chronically implanted electrodes connected to a neurostimulator, programmable in amplitude, pulse width, frequency, and stimulation channel. DBS is a promising treatment option for addressing severe and drug-resistant movement disorders. The success of DBS therapy stems from a combination of surgical implantation techniques, device technologies, and clinical programming strategies. Changes in device settings require highly trained and experienced clinicians to achieve maximal therapeutic benefit for each targeted symptom, and optimization of stimulation parameters can take many clinic visits. Thus, the development of innovative DBS technologies that can optimize the clinical implementation of DBS will lead to wider scale utilization. This review aims to present engineering approaches that have the potential to improve clinical outcomes of DBS, focusing on the development novel temporal patterns, innovative electrode designs, computational models to guide stimulation, closed-loop DBS, and remote programming. Highlights: Deep brain stimulation has emerged a promising therapeutic option for movement disorders. Collaborations between medicine and engineering will shape the future of DBS devices and delivery. Novel temporal stimulation patterns, electrode designs, personalized computational models are reviewed. Closed-loop DBS systems which adapt to the patients' symptoms are discussed.
