The burst duration control policy algorithm. (A) Burst durations are calculated from sequential crossings of the envelope of the movement band beta power over a participant specific threshold. Green bars indicate physiological burst durations and the transition to red shows when the burst has become pathological (>300 ms). DBS intensity adapts between Imin and Imax in response to the burst durations. (B) The DBS intensity is set to increase and decrease at tolerable ramp rates that are predetermined to be safe for each participant. DBS intensity increases after the minimum burst duration is detected and decreases in intensity after the burst ends and the termination delay has elapsed.
