Summary

Our goal is to temporarily implant the following groups for 540 +/- 30 days:

1. Forearm FAST electrodes

1. Five human partial hand amputees (amputated at the level of the hand) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve.
2. Five human hand and forearm amputees (amputated at the level of the forearm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve .
2. Arm FAST electrodes

1. Five human partial hand amputees (amputated at the level of the hand) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve.
2. Five human hand and forearm amputees (amputated at the level of the forearm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve.
3. Five human hand, forearm and arm amputees (amputated at the level of the arm) with 2 FAST electrodes in the ulnar nerve and 2-5 FAST electrodes in the median nerve.

Conditions
