    Area of Science:

    • Biomedical Engineering
    • Rehabilitation Medicine
    • Neurology

    Background:

    • Skeletal muscle spasticity is a common challenge in spinal cord injuries, affecting patient mobility and quality of life.
    • Current clinical assessments of spasticity rely on subjective manual evaluation, lacking quantitative precision.
    • Objective measurement of spasticity is crucial for effective treatment planning and monitoring rehabilitation progress.

    Purpose of the Study:

    • To develop a clinically applicable, quantitative method for evaluating knee spasticity.
    • To identify the minimal instrumentation required for a rapid and straightforward spasticity assessment.
    • To establish a mathematical model for characterizing spastic extremity behavior.

    Main Methods:

    • Utilized gravity to induce passive knee movement in patients with spinal cord injuries.
