摘要： A method generates signal data which is representative of short and long latency components of myoelectric signals. Production of myoelectric signals is repeatedly evoked in a muscle with triggering events. Myoelectric signal data which is representative of the produced myoelectric signals is stored as a temporal function of the triggering events. The myoelectric signal data is averaged before it is demodulated to produce short latency signal data representative of the short latency components of the myoelectric signals. The myoelectric signal data is also demodulated before it is averaged to produce combined short and long latency signal data. The combined signal data is summed with the short latency signal data to isolate the long latency signal data.
