Researchers simulated walking patterns (normal, caution, danger) using elastic bands. Human adaptability was evaluated, improving classification accuracy to 84.50% with a support vector machine, highlighting its bias potential.

Area of Science:

  • Biomechanics
  • Human Motion Analysis
  • Machine Learning in Healthcare

Background:

  • Distinguishing between normal, caution, and danger walking patterns is crucial for diagnosing mobility impairments.
  • Previous methods may not fully account for human adaptability, potentially introducing bias in gait analysis.

Purpose of the Study:

  • To simulate and classify distinct walking patterns (normal, caution, danger).
  • To evaluate the impact of human adaptability on gait classification accuracy.
  • To develop a machine learning model for improved walking pattern discrimination.

Main Methods:

  • Simulated three classes of walking patterns by attaching elastic bands to lower body joints.
  • Investigated four local motion parameters and evaluated differences using t-tests.

  • Employed a multiclass support vector machine classifier to categorize walking patterns.
  • Assessed human adaptability during the classification tasks.

    • Main Results:

    • Achieved an average classification accuracy of 84.50% using the multiclass support vector machine.
    • Identified human adaptability as a significant factor influencing classification outcomes.
    • Demonstrated that adaptability can introduce bias in continuous data collection for gait analysis.

    Conclusions:

    • The developed multiclass support vector machine model effectively classifies simulated walking patterns.
    • Human adaptability is a critical variable that must be considered in gait analysis and data collection.
    • Future research should focus on mitigating bias caused by human adaptability in clinical settings.
