    ELECTROMYOGRAM (EMG) - a test that records the responses of muscles to electrical stimulation. 
    ELECTRO-EJACULATION - a means of extracting sperm from men with erectile dysfunction by using an electrical probe in the rectum. The sperm can be used to fertilize eggs in the uterus or in a test tube. 
    EMOTION -  a complex feeling state with mental, physical and motor responses. 
    EMOTIONAL APPROPRIATENESS -  the correctness or suitability of feelings evaluated from an objective perspective.

FES has been used in experiments to facilitate grip in individuals with tetraplegia, using a switch activated by shoulder shrug. Other uses include correction of scoliosis, bladder control, electro-ejaculation, phrenic nerve stimulation. 
    FLACCIDITY - a form of paralysis in which muscles are soft and limp.
