Reply: Muscle fiber conduction velocity estimation by the multi-dip method; how deep can you dip?

摘要

We have checked the conduction velocity results, and Drs. Zwarts and van Dijk are correct; the conduction velocity (CV) values are extremely low. We have recalculated the values using another set of channels (the multidip algorithm to calculate the CV uses 4 channels, and we use an 8-channel electrode array that allows us to use another group of 4 consecutive channels), and the results were higher. Therefore, the lower values obtained previously, may be related to a selection of noisier channels for the conduction velocity calculation. In addition, we found that the CV values of the dynamic contractions were lower than the range of values that Dr. Zwarts stated in his letter. This may be related to an increase in movement artifacts when the muscle contracts during dynamic contractions that may degrade the quality of the EMG signal.We apologize for any inconvenience, and the new results are listed below. In addition, we would like to point out that, although the values were re-calculated, the statistical results are similar. Therefore, the conclusions we reached in the study do not change.Muscle Conduction Velocity (CV) during Dynamic Contractions.
