[0093] Example 1
[0094] After the above steps S1 and S2, 200 IMU and sEMG signal samples are collected, a deep learning model is constructed through S3 and the training process is completed to obtain the automatic evaluation deep learning model H. For subject A whose upper limb motor function level is unknown, the sensor signals of the shoulder touching process are collected through steps S1 and S2, Figure 4 (a) is a schematic diagram of the three-axis acceleration signal of the forearm IMU, Figure 4 (b) Schematic diagram of the sEMG signal of the biceps brachii. Input all the two signals collected into H, and the Brunnstrom staging result of A’s upper limb motor function is output as VI. Since A is a healthy subject in this example, the model automatically evaluates patient A correctly. There is no physician involved in the process, and only the subject himself or a family member assists in completing the sensor binding work.
