Area of Science:

  • Biomechanics
  • Occupational Safety
  • Data Mining

Background:

  • Stumbles are frequent workplace accidents, often leading to severe injuries, especially with common movements or high heel use.
  • Understanding plantar pressure during stumbles is crucial for preventing falls.

Purpose of the Study:

  • To assess data mining feasibility for identifying stumble-related occupational safety risks.
  • To differentiate stumbling gait from normal gait using plantar pressure analysis.

Main Methods:

  • Analyzed plantar pressure distribution using power spectrum density (PSD) and Support Vector Machine (SVM).
  • Employed PSD for mathematical signal description and SVM for stumble classification.
  • Collected dynamic plantar pressure data from twelve healthy participants.

Main Results:

  • Plantar pressure patterns during stumbles significantly differed from normal gaits qualitatively and quantitatively.
  • The proposed method achieved a mean recognition accuracy of 96.7% for stumble detection.

Conclusions:

  • Enhanced understanding of stumbles provides a basis for addressing occupational injuries.
  • Stumble recognition can predict falls, offer warnings, and aid in designing fall prevention devices.
