Which statement about sensory processing in Down syndrome is accurate?

• A. Sensory self-stimulation behaviors like rocking and bruxism are not observed
• B. There is decreased proprioception processing
• C. Children with Down syndrome have enhanced postural control
• D. There is improved balance under challenging tasks

Answer: (B)

Proprioception provides the sense of where your body parts are in space and how they are moving, and it is essential for precise movement and balance. In Down syndrome, proprioceptive processing is often diminished, which helps explain the motor coordination delays and postural control difficulties commonly observed. When proprioceptive feedback is weaker, individuals may rely more on visual cues and have slower, less accurate movements, especially in tasks that challenge balance or require coordinated limb positioning. This makes decreased proprioception processing the most accurate statement.

Self-stimulation behaviors like rocking or bruxism can occur in individuals with sensory processing differences, so saying they are not observed isn’t accurate. Also, postural control is typically not enhanced in Down syndrome; they usually have poorer balance and sway, particularly under challenging tasks, due to hypotonia, joint laxity, and sensory integration challenges.
