WebWhat is a polyphasic muscle? The motor unit potential (MUP) is a compound potential generated by the muscle fibers of the motor unit during voluntary activity or during electrical stimulation of alpha-motor axons. MUPs are usually biphasic or triphasic in shape, and if they have more than four phases they are denoted as polyphasic. WebFeb 1, 2024 · Triphasic waves are abnormal electroencephalogram (EEG) waveforms seen in association with multiple clinical conditions, including encephalopathy and structural brain lesions, among others.
