In sensory ataxia, which statement is true?

In sensory ataxia, vision indeed serves as a compensatory mechanism for the sensory deficits experienced by the patient. When individuals have a compromised proprioceptive system, particularly in conditions affecting the dorsal columns of the spinal cord or peripheral sensory nerves, they can struggle with maintaining balance and posture without visual assistance. When their eyes are open, they can use visual input to help correct their balance, making it possible for them to maintain a more stable posture.

In contrast, when the eyes are closed, patients with sensory ataxia typically demonstrate increased instability and may sway or stumble due to a lack of proprioceptive feedback. This highlights the reliance on visual cues for maintaining balance in these individuals. Thus, while sensory loss does affect balance and coordination, vision can effectively aid in compensating for those losses when available.
