Background:

Functional electrical stimulation (FES) aids stroke recovery but struggles with intention recognition and adaptability.
Current FES systems lack closed-loop control for dynamic modulation based on patient needs.

Purpose of the Study:

To develop and evaluate a novel reconstruction system for upper limb motor function in stroke patients.
To improve FES adaptability and control using advanced sensor technology.

Main Methods:

Utilized highly pressure-sensitive liquid metal magnetorheological elastomers (LMMRE) to detect muscle surface pressure.
Developed a system to dynamically modulate FES based on detected muscle force signals for continuous wrist movement.
Employed functional near-infrared spectroscopy (fNIRS) to assess brain activity.

Main Results:

The LMMRE-FES system significantly improved wrist lifting angles (14° to 47°) and nearly doubled lifting speed.
Clinical trials demonstrated superior efficacy in promoting motor recovery and reducing muscle spasms compared to conventional FES.
fNIRS indicated enhanced brain activity and neural pathway reconstruction with the LMMRE-FES therapy.

Conclusions:

The developed LMMRE-FES system offers a promising approach for stroke rehabilitation, enhancing motor function and neural recovery.
This technology has the potential for creating advanced, wearable devices for home-based stroke care.
