No clue what this can do to get survivors recovered. A complete failure of the mentors and senior researchers to state EXACTLY what stroke research is for; TO GET SURVIVORS RECOVERED!
No protocols delivered or results discussed; so useless!
Abstract:
Stroke-related upper limb motor impairment frequently leads to chronic muscle weakness and reduced functional mobility, significantly affecting patients’ independence and quality of life. Functional Electrical Stimulation (FES) combined with surface electromyography (sEMG) feedback has shown significant potential in promoting neuroplasticity and supporting motor recovery by reinforcing the association between voluntary intention and muscle activation. However, existing systems typically rely on multiple independent devices for signal acquisition, processing and stimulation. This fragmented architecture increases cost, size, latency and integration complexity. This work presents a new wearable hardware platform that integrates sEMG acquisition and FES delivery within a single compact module. The proposed solution embeds an ADS1299- based front-end for low-noise sEMG recording and a digitally controlled high-voltage stimulator, enabling simultaneous acquisition and stimulation in two muscle groups. The platform supports a bilateral closed-loop rehabilitation paradigm in which voluntary sEMG activity recorded from the dominant arm is used to drive FES delivered to the contralateral limb. In this study, a trigger-based control strategy is adopted, whereby stimulation is activated when the root mean square (RMS) of the processed sEMG signal exceeds an adaptive threshold, and preliminary experimental results demonstrate the feasibility of the proposed system for bilateral sEMG-driven FES applications in post-stroke rehabilitation.
