The present invention provides a method, device, and apparatus for predicting human muscle state, relating to the technical field of muscle state prediction. The method comprises: obtaining target human posture data of a target object through motion capture technology; inputting the target human posture data into a posture-muscle state mapping model, and obtaining a predicted muscle state change sequence corresponding to the target object, output by the posture-muscle state mapping model; the posture-muscle state mapping model is trained based on electromyographic signal sample data and posture sample data corresponding to the electromyographic signal sample data. The present invention predicts muscle state using human posture data and a pretrained posture-muscle state mapping model. Compared to existing technologies, this method eliminates the need for real-time electromyographic signal acquisition, reduces human labor costs, and expands application scenarios and applicable environments.

The utility model relates to the technical field of muscle rehabilitation, in particular to a pelvic floor muscle rehabilitation device which comprises a device body, the top end of the device body is spirally connected with a round head, the bottom end of the device body is fixedly connected with an inflation nozzle, the side edge of the device body is fixedly connected with an expansion air bag, and the side edge of the device body is in contact with an elastic sleeve. The bottom end of the device body is fixedly connected with a fixing block, and the inner side of the device body is provided with a storage groove. Air is conveyed to the inner side of the inflation nozzle, so that the inflation nozzle conveys the input air to the inner side of the expansion air bag through an air conveying groove, and the expansion air bag begins to expand and become large; by enlarging the expansion air bag, a user can be expanded better when using the device, so that the user can obtain higher-level exercise experience on the premise that rehabilitation apparatuses of different sizes are not replaced, the application range of the device is widened, and unnecessary capital expenditure of the user is reduced.

This invention discloses a method for reconstructing a three-dimensional motion and joint force dynamic model of the jaw system, relating to the field of medical technology. The method includes: S1, acquiring a multimodal dataset synchronously collected through a multimodal sensing system and unified to a skeletal coordinate system based on the mandible and temporomandibular joint; S2, constructing an individualized mandibular musculoskeletal model based on the patient's jaw CT image data; S3, using an optimization algorithm, taking the multimodal dataset as input, and under the constraints of the mandibular musculoskeletal model, performing inverse kinematics solution to deduce the six-degree-of-freedom motion trajectory of the mandible in three-dimensional space; S4, based on the six-degree-of-freedom motion trajectory, applying the optimization algorithm and the mandibular musculoskeletal model, and calculating the dynamic contact reaction force distribution of the temporomandibular joint through inverse dynamics analysis; S5, using the dynamic contact reaction force distribution as input, feeding it back to the mandibular musculoskeletal model to calculate the intensity distribution of key muscles involved in mandibular movement.
