[Ectodermal method of Ryodorak--an attempt at clinical measurement for evaluation of physiotherapy effects in patients with low back pain].

In the group of 132 patients with diagnosed pseudoradicular pain syndrome (57 subjects) or evident sciatic neuralgia (75 subjects) besides clinical and radiological examination, additional skin electro-conduction evaluation, being the sympathetic system activity exponent, was performed. Diagnostic part of empiric method of Yoshio Nakatani, was adapted, where the skin electro-conduction measurement of the direct current of 200 microA in 24 representative measuring points is the essence. The aim of this study was the analysis of electroconductivity in dermatomes corresponding to the level of discopathy and indirect trial of objectivisation of some widely applied in this group of patients physiotherapeutical methods: low frequency diadynamic currents (Bernard's), medium frequency interferential currents (Nemec's), low frequency impulse magnetic field and classic acupuncture. In the case of sciatic neuralgia statistically significant electroconductional differences were found in the range of dermatomes involved in pathological process in comparison to the other half of the body as well as other points of reference.
