Functional Electrical Stimulation: Nerve Stimulation and Muscle Contraction

This lecture explores the use of functional electrical stimulation for movement, focusing on nerve and muscle stimulation through electrodes. Topics include stimulation frequency effects, optimal electrode placement, nerve anatomy, and the recruitment of nerve fibers. The lecture also covers the depolarization field triggering muscle contraction, action potential propagation, and collision effects. Additionally, it discusses the optimization of stimulation parameters for target tissues.
