Myopathic units
WebMotor unit recruitment is abnormal in myopathies. We have addressed this subject by recording motor unit potentials (MUPs) using a standard concentric needle electrode in … WebThe 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. Up to 12% of MUPs may be polyphasic in most normal …
