Abstract: This disclosure relates to an immersive ankle rehabilitation training method and electronic apparatus based on upper limb motion signals. The innovation of this technology lies in that: firstly, this disclosure proposes a hybrid model of Regression LSTM corrected by a sliding window based voting algorithm, which predicts the changing angle of the user's wrist joint through wearable EMG sensors; secondly, this disclosure designs and develops two different VR training scenes for users of dorsiflexion and plantar flexion of foot; during the training, users wear VR headwear displays and EMG monitoring devices, to continuously perform wrist dorsiflexion or wrist palm flexion movements, predict the change in wrist joint angles in real-time through forearm sEMG signals, and map it to the contralateral ankle of the avatar in the virtual scene for rotation.
