    Area of Science:

    • Biomechanics
    • Sports Medicine
    • Physical Therapy

    Background:

    • Trunk strength and flexibility are critical for daily activities and athletic performance.
    • Standardized objective measures for trunk function are essential for clinical assessment and rehabilitation.
    • Isokinetic dynamometry offers a controlled method for evaluating muscle strength and performance.

    Purpose of the Study:

    • To assess the feasibility and utility of isokinetic trunk flexion and extension testing in untrained adults.
    • To establish baseline isokinetic parameters for trunk movement.
    • To explore the potential of isokinetic trunk testing for clinical evaluation and rehabilitation.

    Main Methods:

    • 44 untrained adults (23 female, 21 male) participated in the study.

  • Isokinetic measurements of trunk flexion and extension were performed using a Cybex II dynamometer.
  • Subjects completed two trials per day over three days, with each trial including four repetitions at speeds of 30, 60, 90, and 120 degrees/second.

    • Main Results:

    • Data collected included peak torque, range of motion, total work, total power, torque relative to body weight, and flexion/extension ratios.
    • The study analyzed various isokinetic parameters to characterize trunk performance.
    • Results indicated variability in trunk performance metrics across different speeds and individuals.

    Conclusions:

    • Isokinetic testing of the trunk can yield clinically relevant data for evaluation and rehabilitation.
    • A large, diverse database is necessary to establish reliable normative values for trunk isokinetic testing.
    • This methodology holds promise for guiding physical therapy interventions for trunk-related conditions.
