What are common sensory impairments observed in cerebral palsy?

• A. Excessive tactile sensitivity across all modalities.
• B. Lack of light touch sensation, lack of sharp/dull sensation, and lack of proprioception.
• C. Lack of sharp/dull sensation only.
• D. Enhanced vestibular function.

Answer: (B)

In cerebral palsy, sensory processing is often affected alongside motor function, with deficits seen across several somatosensory modalities. Commonly, individuals have reduced or absent light touch, impaired proprioception (knowing limb position), and diminished pain discrimination (sharp vs dull). This pattern—deficits in touch, position sense, and pain perception—fits CP well, because the brain injury can impact multiple sensory pathways that contribute to safe and coordinated movement.

That makes the described combination of impairments across light touch, sharp/dull sensation, and proprioception the best match. By contrast, excessive tactile sensitivity across all modalities is not the most typical presentation, vestibular function is not generally enhanced in CP, and focusing only on sharp/dull sensation misses the frequent involvement of touch and proprioception.
