1. A method for monitoring pain-related responses in a patient, the method comprising the steps of:

  • acquiring at least one first measurement signal from a patient;

    transforming at least one of the at least one first measurement signal into a normalized signal having a predetermined value range, whereby at least one normalized signal is obtained;

    based on the at least one normalized signal, setting a threshold condition; and

    monitoring a rate at which at least one second measurement signal fulfills the threshold condition, wherein each of the at least one second measurement signal is derivable from a corresponding normalized signal and indicative of pain-related activity in the patient.
