First Claim
1. A method comprising:
- storing a predetermined function specifying a relationship between pulse amplitude and pulse width within a memory;
receiving input from a user modifying an electrical charge value of neurostimulation delivered by a medical device; and
modifying a pulse amplitude and a pulse width of the neurostimulation delivered by the medical device according to the function and based on the modification to the charge value.

Abstract
Techniques for programming electrical stimulation therapy intensity based on electrical charge are described. In some examples, a display presents a stimulation intensity value in units of electrical charge, e.g., Coulombs. In such examples, a user may adjust the displayed charge value, rather than pulse amplitude or pulse width, to adjust the intensity of the electrical stimulation therapy. In some examples, a processor determines modifications to pulse amplitude and pulse width based on the modification to the charge value. In some examples, a processor modifies a pulse amplitude and width to achieve a desired charge, while maintaining a relationship between pulse amplitude and width specified by a predetermined function. In some examples, the function may be programmed, e.g., selected or adjusted, by a user.
