Background:

Foot drop is a common impairment affecting gait and mobility.
Functional Electrical Stimulation (FES) offers a potential solution for foot drop correction.
Accurate and reliable control signals are crucial for effective FES systems.

Purpose of the Study:

To investigate and test a real-time system for FES-assisted foot drop correction.
To derive control timing from peripheral sensory nerve signals.
To evaluate the stability and accuracy of the system over an extended period.

Main Methods:

A hemiplegic participant was fitted with cuff electrodes on the sural and peroneal nerves.
An implanted neural amplifier recorded signals from the sural nerve.

An Adaptive Logic Network (ALN) algorithm processed electroneurogram (ENG) signals to control peroneal nerve stimulation.

The system was tested in real-time for 392 days during various walking tasks.

Main Results:

The detection system accurately identified heel strike and foot lift without errors.
The system reliably distinguished between walking and standing states.
The system demonstrated stability throughout the 392-day testing period.

Conclusions:

Adaptive Logic Networks (ALNs) combined with natural sensors provide a stable and accurate control signal for FES.
This approach offers a promising method for FES-assisted foot drop correction.
Real-time nerve signal processing enables effective and reliable FES control.
