[Research on the psychomotor performance of patients with vertebral syndromes at spas].

The influence of radon balneotherapy on the psychomotor performance of 169 male and female patients with vertebral syndromes was investigated. The speed and skill of motor response to various stimuli was measured by the Schoppe apparatus and the Viennese determination apparatus. The analysis of "steadiness" brought no results, whereas all the other parameters tested by the Schoppe and the Viennese devices showed highly significant improvements in the course of spa treatment. It was not possible to differentiate to which specific factors of spa treatment this positive influence can be ascribed.
