The role of feed-forward and feedback processes for closed-loop prosthesis control
Journal of NeuroEngineering and Rehabilitation, 2011 Background It is widely believed that both feed-forward and feed-back mechanisms are required for successful object manipulation. Open-loop upper-limb prosthesis wearers receive no tactile feedback, which may be the cause of their limited dexterity and ...
