More than one class of securities traded together (e.g., one common share and three subscription warrants).

Unit

1. A combination of securities or types of securities packaged together and bought and sold as one. For example, a preferred share may have warrants and/or common shares attached to it when it is sold. See also: Paired shares, Cum warrant.

In the present study, the comparison between the level of activation obtained in different intensities indicates that the difference in the amplitude of the EMG signal, which reflects the number of motor units recruited and the firing rate of these units, occurred between the intensities of 60, 70 and 80%.
This intensity was selected because it allows for recruitment of a sufficient number of motor units in the quadriceps muscle and is generally well tolerated by participants.

EMG signals are essentially made up of superimposed motor unit action potentials [MUAP's] from several motor units.
The very small duration, low amplitude motor unit potentials with the very low amplitude early recruitment pattern observed only over proximal muscles and the absence of any form of spontaneous activity 3 weeks after the onset of weakness seem to be the characteristic EMG changes that correlated well with the clinical picture.
Their control needle EMG studies also showed their improvement with a full recruitment pattern and reinnervation of motor units.
A repeat laryngeal EMG identified fibrillation potentials at rest and no motor unit activation on attempted phonation.
Although this would assure a fast movement, it would involve less than maximum motor unit involvement.
