A tone reducing foot orthosis is indicated to decrease hypertonia and normalize tone. Which statement reflects its purpose?

• A. Indicated to decrease hypertonia and normalize tone
• B. Provides total contact under the foot allowing areas of pressure that function to decrease tone
• C. Increases dorsiflexion range
• D. Reduces arch height

Answer: (A)

The main idea being tested is how tone-reducing foot orthoses work: their goal is to modulate neural tone, not simply alter foot mechanics. By providing targeted sensory input to the plantar surface during standing and walking, these devices can help dampen hyperactive reflexes and promote a more normal muscle tone pattern. That’s why the statement that it is indicated to decrease hypertonia and normalize tone best reflects its purpose. The other options describe mechanical or range-change effects that aren’t the primary aim of this orthosis—it's not mainly about increasing dorsiflexion range, reducing arch height, or guaranteeing total contact for tone reduction.
