Which functional limitation is typically observed in a hypertonic child?

• A. Decreased range of motion
• B. Hyperreflexia
• C. Normal coordination
• D. Improved postural control

Answer: (A)

Increased muscle tone in a child causes muscles to resist movement, so joints don’t pass through their full range. This stiffness leads to a functional limitation of decreased range of motion, making tasks like dressing, grooming, and ambulation more difficult and increasing the risk of contractures if the tone remains high over time. Hyperreflexia can accompany upper motor neuron involvement, but it’s a signs-and-symptoms detail rather than the everyday functional limitation being described. Normal coordination is unlikely when tone is persistently high, and postural control is typically compromised rather than improved.
