Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Neuroprosthetics

Background:

  • Paraplegic locomotion via functional electrical stimulation (FES) requires precise control of stimulation parameters.
  • Real-time detection of gait events is crucial for adaptive FES control but has faced technical limitations.

Purpose of the Study:

  • To develop and evaluate a real-time gait event detection system for paraplegic subjects undergoing FES-assisted locomotion.
  • To improve the accuracy and reliability of gait event timing for closed-loop FES control.

Main Methods:

  • A two-level algorithm processing sensor signals and stimulator patterns was implemented.
  • A fuzzy logic algorithm provided initial gait phase estimates, refined by a second algorithm to determine precise gait event times.
