A neural stimulation system (10) allows the magnitude of electrical stimuli generated by the system to be programmed to a desired level greater than or equal to a minimum perceived threshold and less than or equal to a maximum tolerable perceived threshold. The electrical stimuli are applied through selected groupings of individual electrode contacts (42a, 42b, 42c,...) of a multi-electrode-contact electrode array (40) attached to pulse generation circuitry (30) as either cathodes or anodes. The electrode array (40) is implanted so that the individual electrode contacts are in contact with the body tissue (44) to be stimulated. Stimulating electrical current pulses, defined by a prescribed set of stimulus parameters are generated and applied to the selected electrode contacts so as to flow from the anode electrodes t o the cathode electrodes. The perceived magnitude of the applied stimuli is equalized (FIG. 3B) in order to enable quick, automated, and/or interactive programming of the values of the stimulation parameters.
