    A new microcomputer system objectively measures skeletal muscle function, including force, relaxation, and endurance. This mobile system provides a normal database for clinical comparisons, aiding in the assessment of patient muscle health.

    Area of Science:

    • Biomedical Engineering
    • Physiology
    • Clinical Diagnostics

    Background:

    • Skeletal muscle function assessment is crucial but lacks routine clinical tools.
    • Objective measurement systems are needed for accurate patient evaluation.

    Purpose of the Study:

    • To develop and validate a microcomputer-based system for routine skeletal muscle function analysis.
    • To establish a normal database for the adductor pollicis muscle.

    Main Methods:

    • A mobile system was developed using a Hall-effect sensor, signal processing unit, and microcomputer.
    • The system measures force-frequency characteristics, relaxation rate, fatiguability, and endurance.
    • One hundred normal volunteers were studied to create a reference database.

    Main Results:

    • The system successfully measured various skeletal muscle function parameters.
    • A normal database for the adductor pollicis muscle was established.
    • The system demonstrated favorable comparison with existing objective measurement methods.

    Conclusions:

    • The developed microcomputer system offers a viable solution for routine clinical examination of skeletal muscle function.
    • It provides a refined technique for evaluating muscle endurance and aids in comparing patient data to normal values.
