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.
