Classification of Functional and Dysfunctional Low Back Pain by Spectral Indicators of Electromyogram

Low back pain is the leading cause of disability. From the pathophysiological point of view, there are functional and dysfunctional types of pain. Functional pain has an identified organic cause in the form of direct tissue damage and activation of peripheral pain receptors or damage that affects the somatosensory system. Dysfunctional pain is formed due to neurodynamic disorders in the central nervous system. As a rule, when examining patients with dysfunctional pain, it is not possible to identify organic diseases that could explain the occurrence of the pain syndrome. This work is devoted to the study of the possibilities of classification methods for differentiating functional and dysfunctional pain according to the spectral parameters of the electromyographic signal.
