Brain-computer interface controlled prosthetic arms can enable people with tetraplegia to perform functional movements. However, vision provides limited feedback as information about grasping objects is best relayed through tactile feedback. We supplemented vision with tactile percepts evoked using a bidirectional brain-computer interface that records neural activity from motor cortex and generates tactile sensations through intracortical microstimulation of somatosensory cortex. This enabled a person with tetraplegia to substantially improve performance with a robotic limb; trial times on a clinical upper-limb assessment were reduced by half, from a median time of 20.9 to 10.2 s. Faster times were primarily due to less time spent attempting to grasp objects, revealing that mimicking known biological control principles results in task performance that is closer to healthy human abilities. Creating artificial tactile feedback through intracortical microstimulation greatly improves the ability of a person with tetraplegia to manipulate objects with a brain-controlled robotic limb.
