Electrical stimulation intervention knee joint brace

The invention discloses an electrical stimulation intervention knee joint brace which comprises a signal abnormity judgment module used for judging whether a muscle contraction mode is abnormal or not in the walking process according to collected electromyographic signals. The standardization processing module is used for performing difference judgment processing on the acquired time sequence and the standard time sequence according to the mean value and variance of the muscle contraction degree time sequence acquired by each myoelectric electrode channel and the corresponding standard muscle contraction time sequence; obtaining a standardized acquisition time sequence and a standardized standard time sequence; the cross-correlation function calculation module is used for calculating a cross-correlation function of a standardized acquisition time sequence and a standardized standard time sequence, the conversion module is used for converting the cross-correlation function into a continuous integral form funct
