What is Understanding Electromyography (EMG) about?
EMG measures and records the electrical activity of muscles using surface or needle electrodes. Surface electrodes monitor overall muscle electrical activity, while needle electrodes observe activity of few fibers. Abnormal spontaneous activity in the EMG signal indicates nerve or muscle cell damage. EMG signals are made up of overlapping motor unit action potentials, and the shape of the EMG waveform provides information about muscle fiber number and type. EMG is used to diagnose neuropathies and myopathie
