Abstract Summary
The purpose of the study was to develop and examine a new functional skill test with an upper extremity prosthesis, involving fundamental upper limb motor functions such as reaching, grasping, carrying, placing, releasing, and retrieving an object. The test scores (total time, accuracy, and efficiency) were distributed in a wide range in intact adults using body-powered simulated prosthesis. The scores improved after a practice session with or without transcutaneous vagus nerve stimulation and one day after the practice. The results provided a proof of concept and demonstrated the feasibility of the new motor skill test with upper limb prosthesis.
