what the risks are electromyography, emg, myogram, electromyography, test that assesses the health, the muscles, nerves controlling the muscles, an emg, a needle electrode is inserted, the skin, muscle, electrical activity detected by this electrode is displayed on an oscilloscope, heard, a speaker, after placement, the electrodes, contract the muscle, by bending arm, presence, the wave form, the action potential, produced on the oscilloscope provide information, the ability, the muscle to respond, the nerves, stimulated, a nerve conduction velocity test, performed in conjunction, an emg, no special preparation, to ensure accurate readings, avoid using any creams, lotions on the day, infants, children, test depends on child's age, level of trust, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, there some discomfort, insertion, the electrodes, similar to an intramuscular injection, muscle, feel tender, bruised, emg, often used, people have symptoms of weakness, examination shows impaired muscle strength, to differentiate primary muscle conditions from muscle weakness, neurologic disorders, muscle tissue, electrically silent at rest, once the insertion activity, trauma of needle insertion, quiets down, no action potential on the oscilloscope, muscle is voluntarily contracted, action potentials begin to appear, contraction is increased, muscle fibers produce action potentials, a disorderly group of action potentials of varying rates, amplitudes, complete recruitment, interference pattern, appears, full contraction, disorders, conditions that cause abnormal results, polymyositis, denervation, reduced nervous stimulation, carpal tunnel syndrome, amyotrophic lateral sclerosis, als, myopathy, muscle degeneration, a number of disorders, muscular dystrophy, myasthenia gravis, alcoholic neuropathy, axillary nerve dysfunction, becker's muscular dystrophy, brachial plexopathy, cervical spondylosis, common peroneal nerve dysfunction, dermatomyositis, distal median nerve dysfunction, duchenne muscular dystrophy, facioscapulohumeral muscular dystrophy, landouzy-dejerine, familial periodic paralysis, femoral nerve dysfunction, friedreich's ataxia, guillain-barre, lambert-eaton syndrome, mononeuritis multiplex, mononeuropathy, peripheral neuropathy, radial nerve dysfunction, sciatic nerve dysfunction, sensorimotor polyneuropathy, shy-drager syndrome, thyrotoxic periodic paralysis, tibial nerve dysfunction, ulnar nerve dysfunction, bleeding, minimal, infection, electrode sites, minimal risk, trauma, muscle from emg, false results on blood tests, creatine kinase, a muscle biopsy, tests.
