In one embodiment, a method of identifying a cause of intermittent interruption in stimulation therapy, comprises: communicating a signal by an external controller device to an implantable pulse generator to initiate a diagnostic mode; generating a stimulation pulses by the implantable pulse generator for application to tissue of the patient through one or more electrodes of a stimulation lead during the diagnostic mode; measuring impedance values for stimulation pulses applied to tissue of the patient through the stimulation lead during the diagnostic mode; directing the patient to perform one or more physical movements while the implantable pulse generator is operating in the diagnostic mode; processing the impedance values to identify time-domain limited variations in the impedance measurements from an expected value range; and displaying on the external controller device identification of one or more electrodes exhibiting intermittent electrical breaks or shorts in accordance with the processed impedance measurements.
