    Area of Science:

    • Neuroscience
    • Biomedical Engineering
    • Medical Devices

    Background:

    • Parkinson's Disease (PD) management often requires Deep Brain Stimulation (DBS) surgery when medications become ineffective or intolerable.
    • Accurate assessment of motor symptoms, like wrist rigidity, is crucial for optimizing DBS electrode placement and stimulation parameters.
    • Current clinical evaluation of wrist rigidity is subjective, relying on neurologist experience and qualitative assessments.

    Purpose of the Study:

    • To develop and validate a novel, wearable motion sensor system for quantitative assessment of wrist rigidity in PD patients.
    • To improve the objectivity and reliability of intra-operative evaluations during DBS surgery.
    • To provide a quantitative scale for classifying wrist rigidity and detecting cogwheel rigidity.

    Main Methods:

    • Design of a comfortable, wireless wearable motion sensor utilizing angular speed measurements.
    • Development of a robust signal descriptor and a polynomial mathematical model for quantitative rigidity classification.
    • Validation of the system's ability to distinguish rigid from non-rigid states and detect cogwheel rigidity.

    Main Results:

    • The developed signal descriptor significantly differentiated between non-rigid and rigid wrist states (p<0.05).
    • The classification model achieved 83.9% accuracy in labeling rigidity, validated against expert neurologist agreement.
    • A methodology for detecting cogwheel rigidity demonstrated high sensitivity (0.93).

    Conclusions:

    • The novel wearable motion sensor provides a reliable and objective quantitative evaluation of wrist rigidity.
    • This system enhances the current subjective clinical assessment, aiding in precise DBS parameter tuning.
    • The sensor offers a simple, user-friendly solution for improving surgical outcomes in Parkinson's Disease patients.
