NCT07215481

Brief Summary

The goal of this clinical trial is to evaluate an automated deep brain stimulation (DBS) algorithm developed by Boston Scientific called Illumina 3D for motor symptoms in Parkinson's disease (PD). The main question it aims to answer is: Is this new automated algorithm effective for treating motor symptoms of PD. Fifteen participants are anticipated to be enrolled. Participants are individuals who recently were implanted with DBS in the subthalamic nucleus as part of their regular clinical treatment and are scheduled to have their DBS turned ON for the first time. In addition to their regular clinical visit when their DBS is turned ON by their clinician, participants are tested on DBS settings determined by Illumina 3D (an automated algorithm). Participants are tested on these different settings across different motor tasks, including walking and finger tapping, as well as answering questionnaires. The experiment is expected to last 1 or 2 days; this is not a longitudinal or long-term trial. Participants return to their usual DBS settings once they leave the clinic.

Outcome Measures

Primary Outcomes (1)

  • Change in QDG Mobility Score (OFF DBS to Illumina 3D)

    Quantitative Digitography (QDG) Mobility Score is a single score representing a participant's overall movement proficiency by combining performance across different aspects of movement including speed, frequency, amplitude, and rhythmicity measured using an engineered Keyduo QDG device during an alternating finger pressing and releasing with the index and middle finger. It is represented by a single value between 0 and 100 for each hand, where 100 represents ideal performance. The primary outcome is the difference in QDG Mobility Score from the OFF DBS condition (baseline) to Illumina 3D DBS. The Illumina 3D DBS amplitude condition with the highest QDG mobility score will be used.

Study Arms (1)

Deep Brain Stimulation

EXPERIMENTAL

Participants start with a sham condition (baseline) for approximately 45 minutes. Participants then receive the following four deep brain stimulation conditions in a randomized order for approximately 45 minutes each delivered by the Boston Scientific Vercise Genus neurostimulator. Neither the participants nor the assessor will be aware of what condition they receive. Before starting the condition, there will be a wash in for approximately 15 minutes. Participants will then perform tasks and questionnaires for approximately 30 minutes on each condition. The four conditions are: 1. Standard of Care Deep Brain Stimulation 2. Illumina 3D Deep Brain Stimulation 3. Illumina 3D Deep Brain Stimulation Reduced Amplitude 4. Illumina 3D Deep Brain Stimulation Higher Amplitude

Interventions

Participant's device (Boston Scientific Vercise Genus neurostimulator) is turned off for 45 minutes.

Deep Brain Stimulation

Participant's device (Boston Scientific Vercise Genus neurostimulator) is turned 'ON' for 45 minutes using a configuration and amplitude determined as standard of care by the clinician.

Deep Brain Stimulation

Participant's device (Boston Scientific Vercise Genus neurostimulator) is turned 'ON' for 45 minutes using a configuration and amplitude determined by the automated Illumina 3D algorithm.

Deep Brain Stimulation

Participant's device (Boston Scientific Vercise Genus neurostimulator) is turned 'ON' for 45 minutes using a configuration and amplitude determined by the automated Illumina 3D algorithm but at a reduced stimulation amplitude.

Deep Brain Stimulation

Participant's device (Boston Scientific Vercise Genus neurostimulator) is turned 'ON' for 45 minutes using a configuration and amplitude determined by the automated Illumina 3D algorithm but at a higher stimulation amplitude.
