Embodiment
[0074] Embodiment: An upper limb rehabilitation evaluation method based on the active participation judgment of rehabilitation exercise, the principle block diagram of the overall process is as follows figure 1 As shown, it is characterized in that it includes the following steps:
[0075] (1) Collect myoelectric signals and force signals as the input source data of the fuzzy reasoning model during the rehabilitation training of the upper limb rehabilitation robot;
[0076] The force signal is the pressure F obtained by the pressure force measuring device between the rehabilitation robot and the finger. The smaller and more uniform the pressure F, the lower the patient's participation. Electrical signals collected by the head muscle and deltoid muscle through the surface electrodes.
[0077] (2) Use the Butterworth band-pass filter to filter the EMG signal data obtained in step (1), and set the cutoff frequency to 500 Hz, which is a second-order band-pass filter that can eff...
