There are at least six techniques that are currently in use to estimate<unk> <unk><unk> s. These include incremental stimulation, multi-point stimulation method, F-response method, spike-triggered averaging method and the statistical method. Incremental stimulation is the most illustrative of the concept, and so will be discussed here. According to Henneman's size principle,<unk> <unk>  recruitment is orderly such that smaller<unk>  neurons are recruited before progressively larger ones. Additionally, the<unk> <unk>  action potential is an all-or-none phenomenon - once the recruitment threshold (the stimulus intensity at which a<unk> <unk>  begins to fire) is reached, it fires fully. Electrical stimulation of nerves reverses the recruitment order, due to the lower resistance of the larger<unk>  neuron axons. Incremental stimulation involves gradually increasing the intensity of the stimulus to reach the recruitment threshold of increasing<unk> s of<unk> <unk> s until the intensity of the CMAP is reached. A 'step' is noted when an increase in stimulus leads to an increase in recorded EMG (i.e. another<unk> <unk> 's threshold is reached and it is recruited). The CMAP is then divided by the<unk>  of steps required to reach the intensity of the CMAP to get a mean SMUAP size. The<unk>  of steps does not correlate to the total<unk>  of<unk> <unk> s in the muscle. Instead, the CMAP size is then divided by the mean SMUAP size to get an<unk>  of the<unk>  of<unk> <unk> s in the muscle.
