Astereognosis refers to the inability to recognize objects through tactile sensation alone. This condition occurs when a person cannot identify items by touch without the aid of vision. It can result from neurological disorders affecting the sensory pathways in the brain, particularly those involved in processing tactile information. Individuals with astereognosis may not be able to identify common objects, such as a coin or a key, merely by feeling them in their hands, which can significantly impact their daily activities and independence. Understanding this condition is crucial for rehabilitation nurses, as it informs how they might approach sensory rehabilitation therapies and assist clients in adapting to their limitations.

The other choices pertain to different neurological deficits. Loss of balance and coordination is related to issues with the vestibular system or motor control, while difficulties in processing visual information would involve visual perceptual disorders. Inability to comprehend emotional cues involves challenges in social cognition, which is distinct from sensory recognition through touch. Thus, while they are important concepts in their own right, they do not define astereognosis.
