Phase alignment of ECAPs

A method comprising:

• receiving, by processing circuitry, a first evoked compound action potential (ECAP) signal elicited by a first polarity configuration of one or more stimulus electrodes;
• receiving a second ECAP signal elicited by a second polarity configuration of the stimulus electrodes opposite the first polarity configuration;
• generating an adjusted second ECAP signal by temporally aligning at least one of a P1, N1, or P2 peak of the second ECAP signal to at least one of a corresponding P1, N1, or P2 peak of the first ECAP signal;
• generating a composite ECAP signal based on the first ECAP signal and the adjusted second ECAP signal;
• and
• controlling, by the processing circuitry and based on the portion of the composite ECAP signal, stimulation circuitry to deliver the electrical stimulation therapy via the one or more stimulus electrodes.

A non-transitory computer readable medium comprising instructions that, when executed, cause processing circuitry to:

• receive a first evoked compound action potential (ECAP) signal elicited by a first polarity configuration of one or more stimulus electrodes;
• receive a second ECAP signal elicited by a second polarity configuration of the stimulus electrodes opposite the first polarity configuration;
• generate an adjusted second ECAP signal by temporally aligning at least one of a P1, N1, or P2 peak of the second ECAP signal to at least one of a corresponding P1, N1, or P2 peak of the first ECAP signal;
• generate a composite ECAP signal based on the first ECAP signal and the adjusted second ECAP signal;
• and
• control, based on the portion of the composite ECAP signal, stimulation circuitry to deliver the electrical stimulation therapy via the one or more stimulus electrodes.
