2. In a child with spastic diplegic cerebral palsy, the PRIMARY goal of AFO prescription is to:
Improve functional mobility, gait efficiency, and energy expenditure

AFOs for children with cerebral palsy are prescribed to normalize gait kinematics, reduce energy expenditure, and maximize functional independence in mobility.

3. What documentation practice is considered essential in Spinal Orthotic Devices within the Certified Orthotic Fitter field?
Recording actions, observations, and outcomes in real-time or as close to the event as possible

Real-time or near-real-time documentation in Spinal Orthotic Devices ensures accuracy, provides a contemporaneous record, and is considered the gold standard for professional accountability and legal defensibility.

4. Why is patient education important after fitting?
