A system for treating a patient, comprising: a signal generator that includes signal generation circuitry; and a computer-readable medium operatively coupled to the signal generation circuitry and programmed with instructions that, when executed: direct a first, sensory stimulation signal to the patient to elicit a first sensory response; receive an indication of a first sensory threshold of the patient corresponding to the first sensory stimulation signal; direct an electrical signal to a neural population of the patient at a frequency in a frequency range of 1.5 kHz to 100 kHz; while and/or after directing the electrical signal to the patient, direct a second sensory stimulation signal to the patient to elicit a second sensory response; receive an indication of a second sensory threshold of the patient corresponding to the second sensory stimulation signal; and if the second sensory threshold is less than the first sensory threshold, perform one of the following actions: identify the patient as a candidate for receiving an electrical therapy signal at a frequency in a frequency range of 1.5 kHz to 100 kHz; or change a signal delivery parameter in accordance with which the patient receives therapy via an electrical therapy signal. a signal generator that includes signal generation circuitry; and a computer-readable medium operatively coupled to the signal generation circuitry and programmed with instructions that, when executed: direct a first, sensory stimulation signal to the patient to elicit a first sensory response; receive an indication of a first sensory threshold of the patient corresponding to the first sensory stimulation signal; direct an electrical signal to a neural population of the patient at a frequency in a frequency range of 1.5 kHz to 100 kHz; while and/or after directing the electrical signal to the patient, direct a second sensory stimulation signal to the patient to elicit a second sensory response; receive an indication of a second sensory threshold of the patient corresponding to the second sensory stimulation signal; and if the second sensory threshold is less than the first sensory threshold, perform one of the following actions: identify the patient as a candidate for receiving an electrical therapy signal at a frequency in a frequency range of 1.5 kHz to 100 kHz; or change a signal delivery parameter in accordance with which the patient receives therapy via an electrical therapy signal. direct a first, sensory stimulation signal to the patient to elicit a first sensory response; receive an indication of a first sensory threshold of the patient corresponding to the first sensory stimulation signal; direct an electrical signal to a neural population of the patient at a frequency in a frequency range of 1.5 kHz to 100 kHz; while and/or after directing the electrical signal to the patient, direct a second sensory stimulation signal to the patient to elicit a second sensory response; receive an indication of a second sensory threshold of the patient corresponding to the second sensory stimulation signal; and if the second sensory threshold is less than the first sensory threshold, perform one of the following actions: identify the patient as a candidate for receiving an electrical therapy signal at a frequency in a frequency range of 1.5 kHz to 100 kHz; or change a signal delivery parameter in accordance with which the patient receives therapy via an electrical therapy signal. identify the patient as a candidate for receiving an electrical therapy signal at a frequency in a frequency range of 1.5 kHz to 100 kHz; or change a signal delivery parameter in accordance with which the patient receives therapy via an electrical therapy signal.
