Area of Science:

  • Biomechanics
  • Signal Processing
  • Wearable Technology

Background:

  • Gait parameter measurement offers crucial health and safety insights.
  • Automatic gait analysis using kinematic sensors is an emerging research field.

Purpose of the Study:

  • To develop and evaluate a novel method for detecting walking and measuring gait cadence.
  • To utilize time-frequency signal processing and spectrogram analysis for gait assessment.

Main Methods:

  • Employing a chest-worn inertial measurement unit (IMU) to collect kinematic data.
  • Applying time-frequency signal processing and spectrogram analysis for signal interpretation.
  • Conducting a pilot study with 11 participants to validate the method.

Main Results:

  • The proposed method achieved up to 88.70% sensitivity in distinguishing walking from non-walking activities.
  • The method demonstrated a specificity of 97.70% for activity detection.
  • Identified limitations include threshold-level instability requiring manual fine-tuning.

Conclusions:

  • The developed method shows promise for automatic gait analysis and cadence measurement.
  • Further research is needed to address the limitations and improve robustness.
  • This approach could enhance remote health monitoring and safety applications.
