Automatic adjustment to maintain evoked potential feature

A method, comprising:

• delivering electrical current defined by adjustable stimulation parameters to at least one electrode to provide at least one evoked potential feature, wherein the adjustable stimulation parameters have a defined relationship to the at least one evoked potential feature and include at least a first stimulation parameter and a second stimulation parameter;
• and
• adjusting at least the first stimulation parameter, and then maintaining the at least one evoked potential feature at a substantially constant level by automatically adjusting at least the second stimulation parameter, using the defined relationship, in response to adjusting the at least the first stimulation parameter.

A non-transitory machine-readable medium including instructions, which when executed by a machine, cause the machine to:

• deliver electrical current defined by adjustable stimulation parameters to at least one electrode to provide at least one evoked potential feature, wherein the adjustable stimulation parameters have a defined relationship to the at least one evoked potential feature and include at least a first stimulation parameter and a second stimulation parameter;
• and
• adjust at least the first stimulation parameter, and then maintain the at least one evoked potential feature at a substantially constant level by automatically adjusting at least the second stimulation parameter, using the defined relationship, in response to adjusting the at least the first stimulation parameter.
