What is Electroneuromyography (ENMG)?
Electroneuromyography (ENMG) is a diagnostic method that is used to register action potentials of muscle motor units and examine the conduction of peripheral nerves. The method of electrical stimulation of nerves and measurement of conduction velocity is called electroneurography (ENG), and the method of registering action potentials of motor units, spontaneous and insertional activity of muscles is called electromyography (EMG).
ENMG is a diagnostic method for determining diseases and damage to the peripheral nervous system. This involves examining part of the nervous system from the body of the nerve cell in the spinal cord (motor neuron), through the roots of nerves (radix), bundles of nerves (plexus), peripheral nerves, neuromuscular synapses and muscles.
ENMG as a supplementary diagnostic method should answer the following questions:
- Is it a peripheral and central motor neuron disease?
- Is the muscle pathologically changed, or not?
- Is the change myogenic or neurogenic?
- If it is neurogenic, does it correspond to a spinal lesion, or a peripheral nerve lesion?
- Is the change localized, or does it involve multiple muscles?
- Is the denervation complete or partial?
- Is the process active or stationary, progressive or with compensatory or reinnervation elements?
- Is it a disorder of neuromuscular synapse function, which is found in myasthenia gravis and myasthenic syndrome?
- Is it polyneuropathy or radiculopathy?
When is ENMG needed?
Neurological diseases in which it is necessary to perform ENMG are:
- Degenerative diseases of the spinal column, primarily discus. Is there pressure of the discs on the nerve roots and their consequent damage.
- Peripheral nerve injuries
- Diabetes mellitus, to determine whether complications of the underlying disease have developed in the form of diabetic polyneuropathy.
- All neurological diseases affecting the peripheral nervous system (motor neuron disease, neuropathies), muscle diseases (myopathy, muscular dystrophy), diseases in which there is a disorder at the level of the neuromuscular junction (myasthenia gravis and myasthenic syndrome).
- Patients who have chronic tingling in the feet, legs and hands, a feeling of muscle twitching, a feeling of increased fatigue in the muscles of the shoulder girdle or legs, muscle loss, and muscle tension, pain in the cervical spine and arms, pain in the legs accompanied by tingling or saddle region.
ENMG at the NEUROMEDIC polyclinic
ENMG imaging is performed by an extremely professional, highly educated team of neurologists and neurophysiologists, who were educated in this field under the guidance of prof. Dr. Stojanka Đurić, at the Clinic for Neurology in Niš.
Prof. Dr. Đurić and the founder of the Department of Clinical Neurophysiology at the Clinic for Neurology in Niš and educated over 30 doctors in this field. She was educated in Clinical Neurophysiology at the Clinic for Neurology in Ljubljana, at the National Hospital in London and at the Medical Academic Center in Amsterdam. He still deals with electroneuromyography and directs his team of neurologists and neurophysiologists from the NEUROMEDIC polyclinic to education in neurophysiology centers in Europe.
We cite the example of Dr. Vanja Đurić, who was educated in EMNG with Professor Stalberg in Uppsala, Sweden.
