Single fiber EMG evaluation in denervation and reinnervation. 1990

D Wiechers

SFEMG can be used to follow the course of reinnervation. The parameters of fiber density, mean jitter and percent blocking must each be followed and related to the type of injury to determine the stage of reinnervation. The few reported cases in the literature of SFEMG recordings followed over time after nerve compromise are reviewed and an additional case is presented by the author. Mean jitter values can return to normal approximately 1 1/2 years postonset of reinnervation. Some individual recordings may remain abnormal permanently.

D010525	Peripheral Nerves	The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.
