| titleOfInvention | Knee joint musculoskeletal model contact force estimation method and system driven by electromyographic signals |
| abstract | The invention relates to a knee joint musculoskeletal model contact force estimation method and system driven by electromyographic signals, wherein the method comprises the following steps: establishing a contact force estimation model which comprises a signal processing model, an OpenSim individual model, a muscle activation degree model, a muscle contraction mechanics model and an external adduction moment model, wherein the signal processing model is used for preprocessing input data, the OpenSim individual model is used for scaling a general model to individual physiological parameters, the muscle activation degree model is used for acquiring muscle activation degree, the muscle contraction mechanics model is used for acquiring muscle moment, and the external adduction moment model is used for acquiring external adduction moment; performing parameter optimization on the contact force estimation model; acquiring electromyographic signal data, joint angle signal data and plantar pressure signal data, inputting the electromyographic signal data, the joint angle signal data and the plantar pressure signal data serving as input signals into a contact force estimation model after parameter optimization, and calculating to obtain the knee joint contact force. The method and the system are convenient to use and are beneficial to improving the accuracy of contact force estimation. |
