What is the primary functional goal of functional electrical stimulation for CP as described?

• A. Improve walking by lifting the foot during swing
• B. Cure cerebral palsy
• C. Increase leg strength only
• D. Eliminate need for physical therapy

Answer: (A)

Functional electrical stimulation for cerebral palsy is used to improve walking by lifting the foot during the swing phase, providing foot clearance so the toe doesn’t drag. It works by electrically activating the muscles that lift the foot (the dorsiflexors, like the tibialis anterior) at the right moment in the gait cycle, so as the leg swings forward the foot clears the ground. This leads to a more stable, efficient gait and reduces the risk of tripping. It’s not a cure for CP, it doesn’t simply increase leg strength on its own, and it doesn’t eliminate the need for physical therapy; instead, it acts as a functional assist that’s often used in conjunction with therapy to practice and reinforce improved walking patterns.
