What does Functional Electrical Stimulation (FES) primarily aim to achieve?

Functional Electrical Stimulation (FES) primarily aims to facilitate voluntary movement and prevent atrophy. FES is a therapeutic technique commonly used in stroke rehabilitation and other conditions involving motor impairment. It works by delivering electrical pulses to specific muscles or nerves, which helps trigger muscle contractions. This stimulation can enable individuals to perform movements they may have lost due to neurological damage.

By promoting muscle activity, FES plays a significant role in maintaining muscle mass and preventing atrophy, which can occur when muscles are not used. This is particularly important in stroke rehabilitation, where muscle weakness can contribute to functional limitations. Additionally, by facilitating voluntary movements, FES assists in the retraining of the motor pathways, enabling better coordination and improving overall functional mobility.

The other options, while relevant to aspects of rehabilitation and health, do not align specifically with the primary goals of FES. Cognitive function improvement relates more to cognitive rehabilitation techniques rather than electrical stimulation. Enhancing emotional regulation is more connected to psychological therapies and interventions. Improving joint stability typically involves physical therapy and strengthening exercises, which are different from the direct electrical stimulation provided by FES.
