Sentence examples for motor unit potential from inspiring English sources
Interference pattern analysis is an electromyographic technique that reproducibly measures muscular recruitment by detecting both "turns" in the electromyographic signal produced by positive and negative peaks of the motor unit potentials and motor unit potential amplitude.
If the motor unit potential is found, it means the axon has been spared.
The neurologist rated the voluntary motor-unit recruitment using the following scale: 0 = full interference, 1 = mixed interference, 2 = simple interference and 3 = without motor unit potential.
In affected TA muscles during phonation with the greatest exertion, preoperative evaluation of voluntary motor-unit recruitment showed that there were 11 cases without motor unit potential, 147 cases with simple interference, 51 cases with mixed interference and no case with full interference.
Motor unit potential changes and maximal recruitment pattern were evaluated with a semiquantitative recording.
The 10 incremental values were averaged to estimate average single motor unit potential (SMUP) amplitude.
Motor unit potentials were strikingly polyphasic, and recruitment of motor unit potentials was mildly reduced in the interosseus I dorsalis muscle and markedly reduced in tibial and gastrocnemius muscles.
Conventional EMG showed normal motor unit potentials morphology and recruitment of all examined muscles in both groups.
Post-operatively, electromyography revealed very few motor unit potentials (MUPs) in left vastus lateralis, vastus medialis, adductor longus, adductor magnus, EHL and gluteus maximus.
For conventional EMG, the pattern of insertional activity, the presence or absence of resting activity, the motor unit potentials morphology at moderate contraction, the pattern of recruitment, and the interference pattern at maximum effort were assessed.
Objectives: To calculate conduction velocities (CV) of single motor axons innervating hand, forearm and leg muscles, weak anodal electrical transcranial stimuli were used and single motor unit potentials were recorded in 17 normal subjects.
