Abstract: Electromyography (EMG) plays a key role in the diagnostic evaluation of ALS. This paper deals with the contribution of conventional needle EMG and electroneurography to the neurophysiological assessment of ALS. In addition, special EMG techniques such as single fibre EMG and macro EMG are discussed as they mirror the decline of the number of motor units during the disease process and the remodelling capacity of the surviving motor units.
