In functional electrical stimulation for cerebral palsy, what pattern of calf muscle improvement is reported?

• A. Improvement is seen immediately after stimulation but not observed after several months
• B. Improvement persists for months after a single session
• C. No improvement is observed at any time
• D. Improvement is observed only with concurrent therapy

Answer: (A)

Functional electrical stimulation for the calf muscles mainly provides an immediate, during-stimulation effect. The electrical pulse causes a contraction that can improve gait or ankle control right away, but without ongoing stimulation and accompanying training, those gains don’t usually persist for months. Lasting improvements require repeated sessions and motor practice to drive neuromuscular adaptations. So the pattern most often seen with a single FES session is improvement right after stimulation, but no lasting change after several months. If therapy is continued or multiple sessions occur, longer-term benefits may develop, but the question describes the typical single-session pattern.
