Portable control systems to operate a hand motor neuroprosthesis for people with tetraplegia

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study compares multiple non‑invasive control interfaces that capture user intent to operate a motor neuroprosthesis delivering neural electrical stimulation for hand grasp. Participants will use each portable interface to control a software demonstration of a motor action while investigators measure reliability and precision of control. The work builds on prior demonstrations that neural stimulation can produce clinically useful grasping movements, but focuses on validating compact, wearable interfaces intended for integration with a future implanted stimulator. Eligible participants perform standardized tasks at the Perpignan rehabilitation center to generate comparable performance metrics across interfaces.
