Closed-loop DBS with movement intention

In this paper we present a prototype proof-of-concept for a closed-loop deep brain stimulation system for patients with essential tremor. This system makes use of sensed movement intentions via EEG to determine when stimulation is required and automatically enables stimulation only when needed. We demonstrate this system using a healthy subject and a benchtop experimental prototype. By limiting stimulation to only when it is therapeutically required, implanted neurostimulators can be more power efficient and potentially limit the period where patients experience side-effects to only the time when therapy is needed.
