Which is a functional limitation commonly observed in hypotonic children?

• A. Increased speed of movement
• B. Limited Antigravity Movements
• C. Normal balance
• D. Enhanced fine motor

Answer: (B)

Antigravity control depends on enough muscle tone to oppose gravity and maintain postures against it. When tone is low, as in hypotonia, the muscles don’t generate enough force to hold joints in anti-gravity positions. That makes it hard to lift and stabilize the head, trunk, and limbs against gravity, leading to limited antigravity movements. In practical terms, infants with hypotonia often have poor head control when on the stomach, struggle to sit without support, and have trouble bearing weight or standing. These challenges reflect a common functional limitation in hypotonia: difficulty moving and maintaining positions against gravity. For context, movements that require fighting gravity—like raising the head, sitting upright, and standing—are areas most often affected. Conversely, increased speed of movement isn’t typical in hypotonia, as the overall tone and voluntary initiation are reduced. Balance is usually not normal, and fine motor skills may be delayed rather than enhanced, though fine motor can be variably affected depending on the individual.
