This invention discloses a coherent electrical stimulation method for idiopathic scoliosis combined with exercise therapy, belonging to the field of electrical stimulation methods for idiopathic scoliosis. It aims to address the problem of how to dynamically adjust stimulation parameters based on individual differences to improve treatment efficacy. The method includes acquiring raw image sequences of the patient's spine through MRI scans, preprocessing the raw image sequences to construct a three-dimensional geometric model of the spine, configuring simulated electrical property parameters for the tissue structures, and then adding coherent electrical surface electrodes to the model. The electrode placement area on the three-dimensional geometric model of the spine is initially defined, and a coherent electrical stimulation signal is generated using a function generator. A comprehensive evaluation index value is calculated through finite element analysis to dynamically adjust the coherent electrical stimulation signal. Based on the coherent electrical stimulation signal parameters and its comprehensive evaluation index value, a coherent electrical stimulation scheme is determined, and ultrasound-guided technology is used to locate the electrode positions and implement coherent electrical stimulation therapy.
