ELECTROMYOGRAPHY AND CONDUCTION VELOCITY STUDIES
Electromyography detects and records electrical activity within muscles in various phases of voluntary contraction.
These studies are useful for diagnosing myopathies and axonal damage in neuropathies. Nerve conduction velocity studies assess the ability of nerves (especially myelinated nerve fibers) to conduct electrically evoked APs in sensory and motor axons. Conduction velocity studies are particularly helpful in evaluating damage to myelinated axons.
