How do orthotics contribute to tone management and functional improvement?

• A. Maintain proper alignment (eg, ankle-foot orthosis for foot alignment), reduce compensatory patterns, and facilitate functional posture and gait
• B. Directly increase muscle strength
• C. Cure spasticity
• D. Replace therapy

Answer: (A)

The main idea is that orthotics support tone management and function by providing stable, proper alignment that reduces abnormal movement patterns and facilitates efficient posture and gait. An ankle-foot orthosis, for example, helps hold the foot and ankle in a more neutral position, which diminishes compensatory patterns created by tone and spasticity. This stabilization lets the limb move with less energy cost and improves knee and hip alignment, making standing and walking more stable and efficient. Orthotics don’t directly increase muscle strength or cure spasticity, and they can’t replace therapy; they work best when used alongside rehabilitation to create a mechanical environment that supports functional movement.
