This application discloses a method, device, equipment, and medium for early warning of tonic-clonic epilepsy. The method includes the following steps: deploying EEG electrode monitoring groups in the left and right ears, and deploying myoelectric electrode groups along the sternal manubrium-xiphoid process line in the chest; calculating the thoracic muscle tonic index based on the root mean square of the first envelope signal and the proportion of time above the individual baseline threshold; if the thoracic muscle tonic index exceeds a specified threshold, a tonic-clonic epileptic seizure is preliminarily determined; enhancing the second envelope signal and calculating the maximum time-delay correlation coefficient based on the second and third envelope signals; if the maximum time-delay correlation coefficient exceeds a specified threshold, a tonic-clonic epileptic seizure is finally determined, and an alarm is issued. By using step-by-step electrode judgment to save energy and combining multimodal synchronization discrimination, the false alarm rate is reduced. By fusing time-domain and cross-modal synchronization indicators and employing hierarchical confirmation logic, the specificity for the tonic phase and the ability to resist motion artifacts are improved.
