Document Summary

Why use nmes: because it is a way to generate muscle contractions for people who have reduced ability to voluntarily activate skeletal muscle. What causes muscle contractions during nmes: they are generated by the simultaneous activation of many motor units. How is functional electrical stimulation different from nmes: fes: anytime stimulation is applied to a muscle for the purpose of producing or assisting a functional movement, not to improve muscle quality of function but to produce a movement. What is a motor unit: a motor neuron and all the muscle fibers it activates. Where can you find motor neurons and what do they do: found in the spinal cord, receive input from upper motor neurons to carry out voluntary muscle activation. Where does the input to motor neurons originate: the primary motor cortex. What is the specificity of control: the fact that each muscle fiber is connected to one motor neuron.
