Variability of electric skin conductivity on selected points as a potential diagnostic and prognostic test in asthmatic children

Diagnostic measurement of electric skin conductivity (ESC) called the Ryodoraku system was introduced in mid 1950s by Nakatani. As has been shown by Ziobro et al. in case of infantile cerebral palsy, changes of ESC may provide a valuable electrophysiological parameter for monitoring a therapy. In this study ESC was measured in asthmatic children treated with a bioelectronic unit VEGA-SELECT. Analysis of results was performed using the Pareto method and an artificial neural network. Significant changes of ESC values were observed, both before and after therapy. The authors suggest that measurement of ESC at Nakatani's points might serve as a useful method for early diagnosis as well as for monitoring a bioelectronic therapy.
