摘要：
Systems, devices, methods, and techniques are described for using evoked compound action potential (ECAP) signals to monitor lead position and/or detect lead migration. An example system includes sensing circuitry configured to sense an ECAP signal, and processing circuitry. The processing circuity controls the sensing circuitry to detect, after delivery of an electrical stimulation pulse, a current ECAP signal, and determines one or more characteristics of the current ECAP signal. The processing circuitry also compares the one or more characteristics of the current ECAP signal to corresponding one or more characteristics of a baseline ECAP signal, and determines, based on the comparison, a migration state of the electrodes delivering the electrical stimulation pulse. Additionally, the processing circuitry outputs, based on the migration state, an alert indicative of migration of the electrodes.
