We have read the letter in response to our paper by McNulty and Hodson-Tole (2015) with great interest. The authors present some possible limits of the use of high-frequency ultrasound (US) to guide microneurography needle insertion. In particular, they state that the best point for needle insertion can be found faster with palpation or percutaneous electrical stimulation. We agree with the authors, but we might add that US may immediately depict the anatomical position of the nerve (in the visible tracts, note that the median nerve is visible in its entire course, from wrist to axilla, in 100% of normal subjects) (Bathala et al., 2014).
