Electromyography (EMG) is an examination of muscle function and peripheral nerve conductivity.
The EMG examination consists of:

• nerve conduction study (NCS), used in the diagnostics of neurogenic diseases: polyneuropathies and mononeuropathies, especially due to compression e.g. carpal tunnel syndrome, amyotrophic lateral sclerosis (SLA), radiculopathy, damage of the brachial, lumbar and sacral plexuses
• muscle examination with the use of a needle electrode (EMG), utilised in the diagnosis of myogenic lesions: congenital and acquired myopathies, myotonias

The examination is also important in the diagnosis of neuromuscular transmission disorders (myasthenia gravis, myasthenic syndromes).
In our EMG office, the examination is performed using the Nicolet “Viking Quest” apparatus.

Contraindications for the examination:

• pacemaker, in case of nerve examination
• taking medications that reduce blood clotting
• the presence of a medical condition that interferes with blood clotting (e.g. haemophilia), if you have a muscle test
• chronic infections
