However few laboratories now rely on invasive near-nerve needle recordings. To my knowledge, the first conduction study on the sural nerve using surface electrodes was by Di Benedetto (1970), predating Buchthal’s 1971 paper, and the next reports using these less-invasive techniques were by Di Benedetto (1972) and Burke et al. (1974). The studied nerve segment in most laboratories has been the calf-lateral malleolus segment but, in a recent issue of Clinical Neurophysiology Practice, Krøigård and colleagues (Krøigård et al., 2021) document conduction for the more distal lateral malleolus-5th metatarsal segment, along the ‘‘dorsal sural nerve”. In an important paper, they present normative values for conduction along this nerve segment in a large cohort (n = 229, aged 21–80 years). While the study is on healthy control subjects, its focus is on the value of these studies in the screening for polyneuropathy, a usage with which I fully agree. In addition, dorsal sural studies may also be of value as a control for an abnormal sensory study on the...
