F wave results
WebF-wave study. F-wave study uses supramaximal stimulation of a motor nerve and recording of action potentials from a muscle supplied by the nerve. This is not a reflex, per se, in … WebAn 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.

WebResults showed that the wave damping coefficient for flattened vegetation (β_F) was 33.6%-72.4% of that for standing vegetation (β_S). Both β_F and β_S increased with wave height but decreased with water depth. A wave attenuation indicator was defined to generate empirical formulas for β_S and β_F as well as their ratio β_F/β_S.
