elektromiográfiája

Elektromiográfiája is the Hungarian term for electromyography (EMG). It is a diagnostic procedure used to assess the health of muscles and the nerves that control them. During an EMG, a needle electrode is inserted into the muscle to record electrical activity. Alternatively, surface electrodes can be placed on the skin. These electrodes detect the electrical signals produced by muscle fibers when they contract and relax. A computer then amplifies and records these signals, which are displayed as waveforms. The pattern and characteristics of these waveforms provide information about the presence of muscle or nerve damage. This examination helps physicians diagnose conditions affecting muscles, nerves, and nerve roots, such as carpal tunnel syndrome, peripheral neuropathy, and muscular dystrophy. It is often performed in conjunction with nerve conduction studies (NCS) to provide a more comprehensive evaluation.
