F wave persistence - measure of alpha motor neuron excitability calculated as the number of F responses elicited divided by the number of stimuli presented. The minimal F wave latency is typically 25-32 ms in the upper extremities and 45-56 ms in the lower extremities. F wave persistence is the number of F waves obtained per the number of ...
There are two types of latency taken into account during the study: onset latency and peak latency. [11] Onset latency is the time it takes for the electrical stimulus to trigger an action potential in the nerve. [11] Peak latency is a representation of the time delay for the signal to travel down the "majority of the axons" in the nerve. [11]
An M-wave, an early response, occurs 3-6 ms after the onset of stimulation. The H and F-waves are later responses. As the stimulus increases, the amplitude of the F-wave increases only slightly, and the H-wave decreases, and at supramaximal stimulus, the H-wave will disappear. The M-wave does the opposite of the H-wave.
Diagram illustrating the relationship between the wavenumber and the other properties of harmonic waves. In the physical sciences, the wavenumber (or wave number), also known as repetency, [1] is the spatial frequency of a wave, measured in cycles per unit distance (ordinary wavenumber) or radians per unit distance (angular wavenumber).

A diagram of the electromagnetic spectrum, showing various properties across the range of frequencies and wavelengths. The electromagnetic spectrum is the full range of electromagnetic radiation, organized by frequency or wavelength. The spectrum is divided into separate bands, with different names for the electromagnetic waves within each band.
