Functional electrical stimulation (FES), also called functional neuromuscular stimulation (FNS), is a technique used to replace or help a muscle contraction during a functional activity by applying an electrical current to the nerves that control muscles. The goal of this treatment modality is to strengthen muscle contraction and improve motor control while accompanying a functional activity. The idea behind FES is that this intervention allows the muscles that are paralyzed or partially paralyzed to move.
Paralysis can occur due to stroke, nerve injury, spinal cord injury, or progressive neurological conditions. Occupational therapists integrate function as an integral part of the process while having the patient engaged with stimulation. Depending on which stage the patient is whether acute, subacute, or chronic, and our clinician’s judgment we recommend muscle stimulation. It is usually combined with regular therapy. There is clear evidence that there are benefits to using FES in comparison to regular therapy, including improved motor hand functioning and dexterity, and increased reaction times.
