Virtual reality could help quadriplegics control hand devices before surgery

This study tested whether virtual reality can be used to evaluate and improve control interfaces for a neuroprosthesis that stimulates hand movements in people with complete tetraplegia (quadriplegia). Ten participants with spinal cord injuries tried two different control methods in a virtual environment to see how well they could grasp and hold objects. The goal was to find a way to customize and practice using the device before it is implanted, making future use more effective and less frustrating.
