HERNANDEZ HERNANDEZ, Bárbara Aymeé et al. Comparison of orthodromic and antidromic stimulation of the sural nerve. Rev Cubana Invest Bioméd [online]. 2004, vol.23, n.2, pp. 112-117. ISSN 1561-3011.
Possible differences in sural nerve responses obtained from the application of antidromic and orthodromic techniques were identified. A study of bilateral conduction of sural nerve was performed in 37 healthy subjects of both sexes under standardized conditions. Student´s t test yielded that there were statistically significant differences between the two sexes regarding variables such as duration of negative phase, amplitude and area obtained from both techniques. Therefore, it was concluded that antidromic stimulation facilitates a response of wider amplitude, better definition and longer duration of negative phase. This might be used as an alternative method to electrophysiologically confirm the sural nerve damage that is not shown by the conventional neurographic methods
