Systems and methods for reducing the likelihood of inducing collateral neural activity during neural stimulation threshold test procedures
First Claim
1. A method of determining a neural stimulation threshold for a patient, comprising:
- applying a test stimulation signal to the patient;
monitoring a neural function of the patient for a response to the test stimulation signal;
determining a neural stimulation threshold corresponding to a lowest intensity test stimulation signal that evokes the patient response; and
based at least in part on the neural stimulation threshold, calculating a set of parameters of a treatment stimulation signal directed toward affecting a neural activity within the patient, wherein the treatment stimulation signal differs from the test stimulation signal with respect to a plurality of parameters.

Abstract
Test procedures for determining a neural stimulation threshold of a patient. In one embodiment, the procedure includes applying a test stimulation signal to the patient and monitoring the patient for a response to the test stimulation signal. The procedure can further include determining a first neural stimulation threshold and calculating a second neural stimulation threshold. The first neural stimulation threshold corresponds to the lowest intensity test stimulation signal that evokes a patient response. The second neural stimulation threshold corresponds to a treatment stimulation signal directed toward affecting a neural activity within the patient.
