NMES, FES, and IFT relieve which symptoms?

• A. Muscle spasms and pain
• B. Hair growth
• C. Bone density
• D. Nerve conduction

Answer: (A)

Electrical stimulation modalities like NMES, FES, and IFT are used to control pain and relax muscle spasm. NMES sends pulses to motor nerves to produce controlled muscle contractions, which helps fatigue overactive muscles and reduce guarding, while the sensory input from the stimulation also helps diminish pain signals. FES does the same type of stimulation but timed to assist functional movements; by promoting more normal movement patterns, it lowers abnormal muscle tone and pain. IFT uses interferential currents to reach deeper tissues with less skin irritation, providing strong sensory input that interrupts pain signals and promotes relaxation of muscles. Together, these therapies target pain and muscle spasm rather than affecting hair growth, bone density, or nerve conduction in a direct, lasting way.
