Why does someone using a prosthetic arm with myoelectric control often struggle to accurately grasp delicate objects based on touch alone?

💡 Explanation

Tactile perception relies on integrated afferent feedback that prosthetic myoelectric systems often lack; sensory information from the prosthetic is not naturally integrated, therefore tactile afferent feedback is artificially decoupled and precise grasping is difficult, rather than alternative explanations involving signal interference or adaptation processes.
