The
EMG Manual is a simple step-by-step approach to
the basic understanding of EMG and Nerve Conductions
studies. It is designed to familiarize the reader
with the basic aspects of nerve conduction studies
and needle examinations and can serve as a guide
to the test, a preparation for the EMG rotation,
or as a simple means for better understanding of
the indications, preparations, interpretation and
performance of EMG Nerve and Conduction studies
Routinely, only the sensory fibers
of the radial nerve are studied because the distal muscles
innervated by this nerve are in the forearm, where the
chances of volume conduction from other muscles are
great. In radial nerve lesions, however, the motor fibers
are studied, with the response recorded from the extensor
difitorum communis.
