“…The baseline F-wave values for both control subjects and post-stroke patients were in agreement with those reported previously (Milanov 1992b;Schiller and Stalberg 1978;Tsai et al 2001). Before footbath treatment, F-wave amplitudes and F/M ratios were higher in affected limbs of post-stroke patients than those in controls or unaffected limbs of patients.…”

“…The F-wave amplitude recorded at rest from the normal AHM was about 1-2% of the M-response amplitude, which was the same order of magnitude as that reported for hand muscles (Upton et al 1971). The small ratio recorded using surface electrodes might be due to repeated activation of a few specific neurons or infrequent responses of most anterior horn cells (Schiller and Stalberg 1978). Fisher et al (1994) published normal values for Fwave amplitudes, with a mean F/M ratio of 2.2±0.7% (range: 1.2-3.5%).…”

“…A higher incidence of F-waves and F-waves of greater magnitude relative to the maximal motor response from a muscle are considered to be a reflection of greater motoneuron excitability [83][84][85]. Although F-wave studies at the single motor unit or muscle fiber level [86][87][88][89] are more difficult to perform, these data can be used to estimate the conduction velocity of the proximal segment of the peripheral axon, a particularly useful feature when ventral root damage is suspected.…”
