Tactile-proprioceptive dysfunction includes which features?

• A. Tactile defensiveness; problems with afferent information; hypersensitivity to input; aversive or atypical response to non-noxious stimuli; avoids touch
• B. Olfactory discrimination deficits
• C. Normal tactile processing
• D. Visual-mound confusion

Answer: (A)

Tactile-proprioceptive dysfunction reflects abnormal processing of touch and body position, leading to heightened or poorly regulated responses to sensory input. The features described—tactile defensiveness (an exaggerated, often aversive reaction to touch), problems with afferent information (difficulty filtering and modulating sensory signals from skin, joints, and muscles), hypersensitivity to non-noxious stimuli, and aversive or atypical responses to touch with avoidance—are classic manifestations. This pattern shows how the tactile system is overly responsive or poorly modulated, which often accompanies proprioceptive challenges that affect body awareness and motor planning. The other choices point to other sensory domains or normal processing, which don’t capture the tactile-proprioceptive presentation.
