Congratulations Drs., Emily Rafferty, Christopher Hess, Adolfo Ramirez-Zamora, Pamela Zeileman, Kelly Foote, Shannon Chiu, and Michael Okun on the publication of “Interactive mobile application for Parkinson’s disease deep brain stimulation (MAP DBS): An open-label, multicenter, randomized, controlled clinical trial.”

Abstract
Introduction
Deep brain stimulation (DBS) is an effective treatment for Parkinson’s disease (PD), but its efficacy is tied to DBS programming, which is often time consuming and burdensome for patients, caregivers, and clinicians. Our aim is to test whether the Mobile Application for PD DBS (MAP DBS), a clinical decision support system, can improve programming.
Methods
We conducted an open-label, 1:1 randomized, controlled, multicenter clinical trial comparing six months of SOC standard of care (SOC) to six months of MAP DBS-aided programming. We enrolled patients between 30 and 80 years old who received DBS to treat idiopathic PD at six expert centers across the United States. The primary outcome was time spent DBS programming and secondary outcomes measured changes in motor symptoms, caregiver strain and medication requirements.
Results
We found a significant reduction in initial visit time (SOC: 43.8 ± 28.9 min n = 37, MAP DBS: 27.4 ± 13.0 min n = 35, p = 0.001). We did not find a significant difference in total programming time between the groups over the 6-month study duration. MAP DBS-aided patients experienced a significantly larger reduction in UPDRS III on-medication scores (−7.0 ± 7.9) compared to SOC (−2.7 ± 6.9, p = 0.01) at six months.
Conclusion
MAP DBS was well tolerated and improves key aspects of DBS programming time and clinical efficacy.
