The invention discloses a myoelectricity feedback based
upper limb training method and
system. The myoelectricity feedback based
upper limb training
system orderly combines
signal acquisition, mode identification,
biological feedback and real-time fatigue evaluation, thereby being capable of helping a user
train the movement function of the
upper limb. The
upper limb training method includes steps of acquiring movement signals and myoelectric signals of the upper
limb joint of the user when the user acts correspondingly such as
forearm rotation and
wrist bending / stretching as completing
virtual game tasks, adjusting movement parameters of
virtual control targets on the basis of the movement signals acquired by the users, identifying several
muscle contraction
modes of the user according to the characteristic parameters of the myoelectric signals, and utilizing the identified
modes as selection basis for a myoelectric
feedback control method. In addition, the
upper limb training system is capable of extracting fatigue characteristics in real time according to the acquired myoelectric signals, analyzing fatigue states of muscles so as to judge
muscle fatigue and send an alarm during the whole interaction system.
