Abstract Background Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is a well-established treatment for Parkinson’s disease (PD). Beyond basic omnidirectional, monopolar stimulation, advanced stimulation settings (AS), such as directional or vertical current steering, variation of pulse width and frequency, bipolar and interleaving stimulation are increasingly available. Our aim was to summarize current evidence on AS in STN-DBS in PD and systemically report their application and potential benefits in clinical routine. Methods In this retrospective single-center observational study, we analyzed stimulation settings of 145 patients with bilateral STN-DBS 3, 6, and 12 months postoperatively. Secondary outcomes included preoperative levodopa response, lead positions, and postoperative reduction of levodopa-equivalent daily dose (LEDD) in patients staying with basic stimulation settings (BS) compared to those initially with AS at 3-months follow-up and those with a change from BS to AS. Results AS were applied in 40.7%, 55.9%, and 73.8% of patients at 3, 6, and 12 months respectively. LEDD reduction after three months was higher in patients remaining with BS or initially AS than in patients with a switch to AS after three months, while there was no difference at 12 months. Median distance of leads to the center of gravity of the motor-STN was slightly larger when AS were applied. Conclusions AS are frequently employed in clinical routine at a specialized DBS center. They may compensate for deviant lead placement in terms of stimulation efficacy measured by postoperative LEDD reduction. Prospective studies are warranted, focusing on specific AS indications in chronic DBS to optimize individual patient outcomes.
