    Summary
    This summary is machine-generated.

    Optimizing deep brain stimulation (DBS) for Parkinson's disease (PD) by minimizing current spread to non-motor areas of the subthalamic nucleus (STN) improved postural stability. This targeted approach offers a potential solution for refractory PD symptoms.

    Area of Science:

    • Neurosurgery
    • Neurology
    • Biomedical Engineering

    Background:

    • Subthalamic nucleus deep brain stimulation (STN DBS) effectively treats advanced Parkinson's disease (PD) motor symptoms.
    • Postural instability often persists despite conventional STN DBS treatment.

    Purpose of the Study:

    • To investigate if optimizing STN DBS by minimizing current spread to non-motor territories can improve postural instability in PD patients.
    • To determine if patient-specific computational models can guide DBS programming for enhanced therapeutic outcomes.

    Main Methods:

    • Developed patient-specific computational models of the subthalamic nucleus (STN) using Cicerone software.
    • Determined optimal stimulation parameters to maximize target activation while minimizing spread to non-motor regions.
    • Assessed postural stability in five PD patients under Off DBS, Clinical DBS, and Model DBS conditions through blinded, randomized evaluations.

    Main Results:

    • Model-guided DBS demonstrated significantly reduced postural sway compared to conventional clinical DBS settings.
    • This suggests that current spread to non-motor STN territories may contribute to residual postural instability.

    Conclusions:

    • Minimizing current spread to non-motor STN territories via model-based DBS programming can enhance postural stability in Parkinson's disease.
    • This approach holds promise for refining STN DBS therapy to address refractory PD symptoms.
