A user may modify a stimulation parameter in a plurality of stimulation programs with a single adjustment. During stimulation therapy, the user, such as a patient, may desire to change a parameter of the plurality of stimulation programs. The patient may press a single button on an external programmer to make the parameter change, or global adjustment, to all of the plurality of stimulation programs. This global adjustment eliminates the need for the patient to navigate through each of the plurality of stimulation programs separately and adjust the parameter. Additionally, changing the plurality of stimulation programs may be desirable for uniform stimulation therapy between programs used by the patient. The external programmer may calculate an appropriate parameter change for each stimulation program to keep parameter ratios equal between the plurality of stimulation programs.
