Area of Science:

  • Biomedical Engineering
  • Gerontology
  • Machine Learning

Background:

  • Aging significantly impacts physical condition, including gait patterns.
  • Gait analysis offers a non-invasive method to assess physical changes associated with aging.
  • Understanding age-related gait modifications is crucial for healthcare and assistive technologies.

Purpose of the Study:

  • To investigate the feasibility of using sensor floor technology and machine learning to estimate human age based on gait patterns.
  • To develop a computational model capable of predicting age from gait features.
  • To evaluate the accuracy and potential applications of this age estimation method.

Main Methods:

  • Utilized electric capacitance sensors embedded in a floor to capture detailed foot-contact data during locomotion.
  • Extracted feature vectors from sensor data, encoding geometrical distributions of significant readings.
  • Trained a Multi-Layer Perceptron (MLP) model for age regression using the extracted gait feature vectors.

Main Results:

  • Achieved a mean absolute error of approximately 10 years in age estimation with a dataset of 142 individuals.
  • The developed feature vector effectively encoded gait cycle parameters like swing-to-stance phase ratio and leg swing execution.
  • Demonstrated the potential of sensor floor data and machine learning for gait-based age prediction.

Conclusions:

  • The combination of sensor floor technology and machine learning presents a promising, novel approach for non-invasive age estimation.
  • This method shows potential for applications in healthcare, particularly in gerontology and patient monitoring.
  • Further research is warranted to refine the model and explore broader clinical applications.
