Different aspects of quantitation, such as motor unit action potential parameters, automatic analysis methods, reference values, and findings in abnormal conditions, are discussed.
Vastus medialis motor unit potential (MUP) parameters were assessed in 8 patients with knee OA and 8 healthy, sex and age-matched controls during submaximal isometric contractions (20% of maximum isometric torque).
Effect parameters included biceps biopsies, motor unit analysis on needle electromyography and computerised muscle tomography, before and after cell therapy.
According to Stashuk et al. (63), the number of motor units in a muscle can be estimated by dividing size-related parameter values measured from a maximal M-Wave by corresponding parameter values measured from an average surface-detected motor unit action potential (S-MUAP).
The CV parameter renders a mean value of the motor unit potentials' propagation velocities.
The secondary endpoints included free platinum pharmacokinetic parameters, EMG detected abnormal spontaneous high-frequency motor unit action potentials, patient-reported neurotoxicity symptoms and study treatment preference for reducing neurotoxicity symptoms at the end of cycle 2.
These parameters were measured in simulated IPs constructed by adding together motor unit action potentials (MUAPs) recorded with a concentric needle EMG electrode.
There were no significant differences between levator ani, external anal sphincter, and published parameters from the biceps muscle with regard to amplitude and duration of motor unit action potentials.
Rate coding governs motor unit firing.
The functional unit of muscle contraction is the motor unit.
