1. A method of determining a neural stimulation threshold for a patient comprising the steps of: applying a test stimulation signal to the patient; monitoring the patient for a response to the test stimulation signal; determining a first neural stimulation threshold corresponding to a lowest intensity test stimulation signal that evokes a patient response; and calculating a second neural stimulation threshold based upon the first neural stimulation threshold, the second neural stimulation threshold corresponding to a treatment stimulation signal directed toward affecting a neural activity within the patient.
