This study developed a computerized lumbar physical examination system using skin markers and an expert system. The automated method accurately identifies abnormal subjects, reducing variability in patient assessment.

Area of Science:

  • Biomechanics
  • Medical Engineering
  • Rehabilitation Medicine

Background:

  • Clinical findings in lumbar physical examinations show low reproducibility, leading to significant variations in treatment, such as surgery rates for disc herniation.
  • Inconsistencies in evaluating low back conditions necessitate standardization for reliable patient assessment and management.

Purpose of the Study:

  • To develop and validate an automated method for lumbar physical examination using an external skin marker system.
  • To assess the system's ability to discriminate between normal and abnormal subjects with high accuracy.

Main Methods:

  • A computerized system tracked skin marker kinematics during flexion-extension and lateral bending movements.
  • Surface electromyography (EMG) recorded multifidus muscle activity.

  • An expert system processed kinematic and EMG data to generate a normality index, comparing patients to a normative database.

    • Main Results:

    • The automated system achieved high accuracy in detecting clinically abnormal subjects (sensitivity 83-91%, specificity >90%).
    • The system provided quantitative data on functional capacities, independent of clinician input.
    • Receiver operating characteristic analysis quantified discrepancies between automated and clinician evaluations.

    Conclusions:

    • Automating the lumbar physical examination with this technique is feasible and yields acceptable error rates.
    • This objective and consistent assessment method eliminates inter- and intra-clinician variability in patient follow-up.
    • The technique enables objective comparison of treatment regimens for lumbar dysfunction.
