Enhanced analysis of uterine surface electromyography

A new approach for the analysis of uterine activity is based on surface electromyography (EMG). It is assumed, that the rising synchronisation between the muscle cells changes the frequency distribution of the EMG-signals. Although first results are very encouraging, the expressiveness of a standard spectrum based on the fourier transform strongly depends on the parturient’s actual state, such as excitement. Therefore, the authors search for an enhanced analysis, which is less influenced by the skin’s conductivity and capacity. This contribution presents an enhanced signal analysis of the electromyography taken…
