Can an upper forearm amputee correctly control the Median and Ulnar nerves I'm an engineer who is looking to build a robotic hand for people without their upper forearm(from center of forearm in direction of hand), controlled by the Thalmic Myo(an EMG sensor). I am first checking for the idea's viability. I was wondering if one who does not have their upper forearm can still send the correct nerve impulses for a desired hand movement through their Median and Ulnar nerves?

**Yes, severed nerves still convey neural responses from the brain**.

In fact, nerve potential recordings in the ulnar and median nerves of the stumps of arm amputees have already been successfully applied to control arm prosthetics (Jia et al. 2007; Kuiken et al., 2007.
