In the context of FES function and cortex effects, which outcome has been reported?

• A. Decreased grasp ability
• B. No functional gains
• C. Decreased strength
• D. Improvement observed on grasp and release, functional use and strength

Answer: (D)

This item tests how FES influences both hand function and brain activity. When electrical stimulation is applied to hand and forearm muscles during purposeful tasks, it enables the nervous system to repeatedly practice grasping and releasing with a clearer, more stable motor output. This repetitive, task-specific practice encourages use-dependent plastic changes in the motor cortex, helping to rewire pathways and improve excitability related to the stimulated muscles.

Because of this combination of functional practice and cortical adaptation, improvements are commonly observed in multiple areas: better grasp and release, greater functional use of the hand in daily activities, and increased strength. So the best answer reflects these broad, reported gains rather than declines in function or a lack of functional improvement.
