1. A method comprising:
- receiving data representative of a relationship between a first therapy parameter value for delivery of a therapy while a patient is in a first position, the first therapy parameter value associated with a first acceleration value and a second therapy parameter value for delivery of the therapy while the patient is in a second position, the second therapy parameter value associated with a second acceleration value, wherein the first position is opposite the second position;
sensing a third acceleration value;
generating a third therapy parameter value for delivery of a therapy to a patient based on the first therapy parameter value and the second therapy parameter value, and a relationship of the third acceleration value to the first and second acceleration values; and
controlling a medical device to deliver the therapy to the patient based on the third therapy parameter value.

Abstract
A medical device provides stimulation therapy to a patient based on a set of therapy parameters. One or more therapy parameters may be automatically adjusted based on acceleration forces detected by a sensor, the acceleration forces being applied to the patient. In some examples, adjustments to one or more therapy parameter may be made based on an algorithm. The algorithm may be defined by acceleration and therapy parameter value pairs associated with opposite patient positions.
