“…Our results showed that the conduction velocity measured in the canine tibial nerve with surface electrodes (60.5 ± 19.1 m/s) provided similar results to previous reports using needle electrodes (60 ± 1.7, 62.2 ± 2.1, 57.1 ± 5.5; Lee and Bowen 1970;Walker et al 1979;Takakura and Inada 1983). Crespo et al (2020) used recording surface electrodes for the evaluation of nerve conduction indicators but did not report the exact velocities in their study.…”

“…The CMAP amplitude depends on many factors and its range is very wide (1-56 mV) across the published studies (Lee and Bowen 1970;Chrisman et al 1972;Takakura and Inada 1983;van Nes and van Den Brom 1986;Crespo et al 2020). In our study, the CMAP amplitude values were in the lower spread which could be a consequence of surface versus subcutaneous recording (much better reproducibility of amplitude and CMAP duration is generally with surface recording electrodes).…”

“…Walker et al (1979) recorded CMAP duration for measuring MNCV in the distal tibial segment 4.0 ms, but whether it was for the negative phase of the action potential was not specified. Crespo et al (2020) recorded a CMAP duration median value of 4.45 ms, but there was no difference in using the needle or surface recording electrodes. We did not find any influence of the rectal temperature (healthy dogs with values within the reference range) on NCV; however, temperature-related changes (decreased conduction in tissue hypothermia) were published in experimental studies (Ichiyanagi et al 1973;Lee and Bowen 1975).…”

“…Lower CMAP amplitudes obtained with surface versus needle recording were confirmed in a recent comparative study, as well. A possible explanation was that skin impedance interfered with recordings to a greater extent (14.97 ± 10.65 mV vs. 9.64 ± 5.13 mV; Crespo et al 2020).…”

“…Electroneurographic evaluation of the tibial nerve in healthy dogs was performed and reported by several authors; however, all of them used needle electrodes to stimulate the nerves directly which is more complicated and requires general anaesthesia (Lee and Bowen 1970;Swallow and Griffiths 1977;Takakura and Inada 1983). One recent study (Crespo et al 2020) described electroneurographic evaluation of the tibial nerve in 25 dogs with orthopedic and neurological symptoms using recording surface electrodes but needle electrodes were used for stimulation.…”

Electroneurography measures the speed of the action potential after nerve stimulation. The aim of this study was to evaluate the motor nerve conduction velocity in the tibial nerve after surface stimulation in healthy dogs, to correlate the obtained data by biological factors, and to compare these results with published findings utilizing needle electrodes. The study was performed in 11 clinically healthy dogs without anaesthesia. There were significant correlations among several indicators (age, limb length, conduction velocity, latency and duration of compound muscle action potentials). Age was found to have a significant effect on the duration of the compound muscle action potential from both stimulation sites (proximal/distal; r = 0.68, r = 0.71, P < 0.05), but there was no effect on the conduction velocity or amplitude of the compound muscle action potentials. Limb length was found to have a significant effect on the duration of the compound muscle action potential from the distal stimulation site (r = 0.64, P < 0.05), a significant effect on the conduction velocity (r = −0.91, P < 0.01), and a significant effect on the amplitude of the compound muscle action potential from both stimulation sites (proximal/distal; r = −0.76, r = −0.63, P < 0.01, P < 0.05 respectively). These results indicate that limb length should be considered as the most important biological factor in tibial nerve conduction studies and that electroneurography in dogs could be performed non-invasively, without a danger of infection, haematomas or complications related to anaesthesia.
