The shape, number and proportion of each component in actual implementation can be arbitrarily changed, and the layout pattern of the components can also be more complex.

[0034] The present embodiment provides a system as shown in Figure 1 and Figure 2The illustrated hip joint rehabilitation method based on multi-parameter real-time monitoring and digital twinning is used for postoperative monitoring of the hip joint of a patient, and includes the following steps: S1, collecting medical image data of the patient, and constructing a hip joint biomechanical model of the patient according to the medical image data; collecting postoperative electromyographic signals of the hip of the patient, hip joint activity angles and joint bearing pressures through a wearable device; S2, correlating the collected postoperative electromyographic signals of the hip of the patient, hip joint activity angles and joint bearing pressures with the hip joint biomechanical model, constructing a digital twinning model of the hip joint of the patient, and dynamically updating the state of the digital twinning model of the hip joint; S3, formulating a visual rehabilitation training scheme according to the dynamically updated state of the digital twinning model of the hip joint, and guiding the patient to perform rehabilitation training through an intelligent display terminal; S4, collecting and recording rehabilitation electromyographic signals of the hip, rehabilitation hip joint activity angles and rehabilitation joint bearing pressures of the patient during the rehabilitation process in real time, and judging the rehabilitation stage of the patient according to the rehabilitation electromyographic signals, the rehabilitation hip joint activity angles and the rehabilitation joint bearing pressures, and the intelligent display terminal dynamically adjusts and displays the rehabilitation training scheme according to the rehabilitation stage of the patient.

[0035] According to the medical image of the patient and the postoperative electromyographic signals, hip joint activity angles and joint bearing pressures, a personalized digital twinning model of the hip joint is constructed, which provides a basis for formulating a rehabilitation training scheme for the patient; dynamically adjusting the rehabilitation training scheme during the rehabilitation process can adjust the rehabilitation training scheme according to the recovery of the patient, ensuring the effectiveness of the rehabilitation process and the safety of the rehabilitation process.

[0036] In order to construct the digital twinning model of the hip joint of the patient, a multi-modal data fusion algorithm is used to correlate the collected postoperative electromyographic signals of the hip of the patient, hip joint activity angles and joint bearing pressures with the hip joint biomechanical model, and construct the digital twinning model of the hip joint of the patient.

Simultaneously, to record the patient's training process based on the animations in real time, the system needs to access the camera of the smart display device (such as a smartphone) to capture the patient's rehabilitation training process.
