    This study introduces a new method for automatically analyzing the Timed Up-and-Go (TUG) test using only video. This approach enables remote monitoring of functional mobility in Parkinson's disease patients.

    Area of Science:

    • Biomedical Engineering
    • Neurology
    • Rehabilitation Science

    Background:

    • The Timed Up-and-Go (TUG) test is a standard for assessing functional mobility in Parkinson's disease (PD).
    • Current automatic TUG analysis methods often require controlled environments or specialized sensors.
    • Sub-task timing within the TUG test provides valuable clinical data for PD assessment.

    Purpose of the Study:

    • To develop and validate an automatic TUG sub-task segmentation method using only video data.
    • To enable objective assessment of functional mobility in PD patients without specialized equipment.
    • To facilitate remote patient monitoring through video-based analysis.

    Main Methods:

    • Utilized deep learning-based 2-D human pose estimation for feature extraction from TUG videos.

    Related Experiment Videos

  • Employed a support vector machine (SVM) and a long short-term memory (LSTM) network for activity classification and sub-task segmentation.
  • Validated the method on videos from 24 Parkinson's disease patients recorded in semi-controlled environments.

    • Main Results:

    • Successfully developed an automatic method for segmenting TUG sub-tasks using video-based activity classification.
    • Demonstrated the feasibility of acquiring clinical parameters from TUG videos alone.
    • The proposed method shows potential for objective and accessible assessment of PD functional mobility.

    Conclusions:

    • Video-only TUG sub-task segmentation is a viable approach for Parkinson's disease assessment.
    • This technology can reduce the need for specialized equipment and controlled settings.
    • The method supports remote monitoring, offering a pathway for continuous patient management.
