ONLINE COVER To Feel Again! A simple electronic cuff placed around nerves in the upper arm of an amputee wearing a prosthetic limb directly activates the neural pathways responsible for hand sensations, enabling the patient to pick up soft fruit such as a cherry. Different stimulation patterns transform the typical "tingling sensation" of electrical stimulation into multiple different natural sensations that enable the amputee to perform a series of fine motor tasks, including pulling the stalk out of the cherry (Tan et al).
