ELECTROMYOGRAPHY PROCESSING APPARATUS, ELECTROMYOGRAPHY PROCESSING METHOD AND ELECTROMYOGRAPHY PROCESSING PROGRAM

An electromyography processing apparatus 1 includes a storage device 10 that stores electromyography data 11 of a predetermined muscle, a pre-processing unit 22 that calculates a root-mean-square value in the electromyography data 11 for each predetermined time and generates root-mean-square value data including the root-mean-square value for each time, and an onset detection unit 23 that sets a sliding window for onset detection to a predetermined time of the root-mean-square value data and determines that a predetermined time is an onset portion if the average of the root-mean-square values in the sliding window is higher than a threshold value, and the onset detection unit 23 further includes a threshold value determination unit 24 that sets a sliding window for threshold value detection to the predetermined time and determines a threshold value based on the average of the root-mean-square values in the sliding window for threshold value detection.
