Summary:A medical method of automatically improving signals received from a patient's physiological system can include delivering stimulation signals to a nerve pathway of a patient with electrical pulses viaelectrodes placed over the nerve pathway to generate a plurality of resultant electrical waveforms (EPs) based on a plurality of electrophysiological responses (ERs); recording the plurality of resultant EPs; generating an ensemble average waveform (EA), the generating comprising averaging a subset of the plurality of ERs; and denoising the EA, the denoising comprising applying a wavelet transform to the EA. 一种自动地改进从患者的生理系统接收的信号的医疗方法，可以包括经由放置在神经通路上的电极用电脉冲将刺激信号传送到患者的神经通路，以基于多个电生理响应(ER)生成多个合成电波形(EP)；记录多个合成EP；生成总体平均波形(EA)，该生成包括对多个ER的子集进行平均；以及对EA进行去噪，该去噪包括将小波变换应用于EA。
