Area of Science:

  • Biomedical Engineering
  • Rehabilitation Technology
  • Neuroscience

Background:

  • Foot switches in Functional Electrical Stimulation (FES) systems for gait restoration face reliability and durability issues.
  • Existing methods for triggering FES during walking often rely on components prone to wear and tear.

Purpose of the Study:

  • To develop and evaluate a portable, motion-driven electrical stimulator (ES) as a reliable alternative to foot switches for drop foot treatment.
  • To enable accurate prediction of gait events like heel strike and toe off using pelvic motion analysis.

Main Methods:

  • A system utilizing a single tri-axis accelerometer on the pelvis, a dual-channel electrical stimulator, and a controller unit was implemented.
  • A post-processing neural network model was employed to analyze pelvic rotation and acceleration data during walking.
  • Gait events (heel strike, toe off) were predicted based on the processed pelvic motion data.

Main Results:

  • The motion-driven ES system demonstrated the ability to predict key gait events accurately.
  • Pelvic motion monitoring proved effective in identifying heel strike and toe off events for FES triggering.
  • The developed system offers a portable and user-friendly solution for drop foot management.

Conclusions:

  • A novel, reliable, and portable electrical stimulator (ES) system for drop foot treatment has been successfully developed.
  • Pelvic motion analysis combined with a neural network provides an effective alternative to traditional foot switches for FES-assisted gait.
  • This technology holds promise for improving the efficacy and usability of FES in gait restoration.
