On nerve conduction studies, the pattern of diminished compound muscle action potential and normal sensory nerve action potential may be seen given that the lesion is proximal to the posterior root ganglion. Needle EMG is the more sensitive portion of the test, and may reveal active denervation in the distribution of the involved nerve root ...
