title: An investigation on chaotic approach to detect functional gastrointestinal disorders.
abstract: Recently, interest has turned to the mathematical concept of chaos as an explanation for a variety of complex processes in nature. Because of this property, it is hypothesized that biomedical signal may be an example of chaos. In this review, some of our basic concepts of nonlinear dynamics and chaos are illustrated. Mathematical techniques developed to study the properties of nonlinear dynamical systems are outlined. Finally, the results of applying these techniques to the study of stomach disorders are discussed. The application of these powerful and novel mathematical techniques to analysis of the Gastric Electrical Activity (GEA) has provided now insights into the Functional Gastrointestinal Disorders (FGD) and may have considerable utility in the diagnosis.
