Which feature best describes tone reducing foot orthosis?

• A. Provides total contact under the foot
• B. Increases arch height
• C. Blocks dorsiflexion
• D. Reduces contact with the plantar surface

Answer: (A)

Tone-reducing foot orthoses work by stabilizing the foot and providing consistent sensory input to help modulate abnormal muscle tone. The feature that provides total contact under the plantar surface achieves this best because it distributes forces evenly across the entire foot, reducing pressure points and improving proprioceptive feedback. This stable, uniform support helps maintain a neutral, more predictable foot position, which can dampen reflexive muscle activity and improve control during standing and gait. Increasing arch height changes the shape of the foot but doesn’t directly address tone modulation. Blocking dorsiflexion restricts movement and can alter gait without improving tone control. Reducing contact with the plantar surface decreases sensory input, which is counterproductive to the neuromuscular feedback the device relies on to reduce tone.
