Summary

This study aims to find the best way to place sensors on a prosthetic socket to improve how well people with below-elbow amputations can control their powered arm. Researchers will compare different numbers of sensors (4, 8, or up to 16) and whether targeting specific muscles helps. Participants will test each setup while performing tasks like packing a suitcase, and their control will be rated by trained observers.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Experimental prosthetic socket with varying numbers of untargeted or targeted EMG channels
What this could lead to
If successful, this could lead to better-fitting, more responsive prosthetic arms that are easier to control in daily life.
What could go wrong
This is a small, early-stage study (32 participants) focused on testing device settings, not a treatment. Results may not apply to all users or lead to immediate product changes.
