Neurostimulation therapy manipulation
First Claim
1. A method comprising:
- calibrating a map that maps directional information to combinations of electrodes from a set of electrodes coupled to a stimulation device, wherein the calibrated map comprises amplitude scale factors associated with at least some of the electrode combinations;
receiving directional information from a directional controller that reflects manipulation of the directional controller by a user;
selecting an electrode combination based on the received directional information and the calibrated map; and
controlling the stimulation device to deliver electrical stimulation to a patient via the selected electrode combination and based on one of the amplitude scale factors that is associated with the selected electrode combination.

Abstract
A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user.
