Abstract
An implantable medical device for stimulating a physiological event in a patient at a stimulation intensity includes circuitry for adapting the stimulation intensity to the physical activity of the patient with refernce to a parameter contained within a physical activity signal obtained from a sensor. Circuitry is also provided for reducing, under certain circumstances, the sensitivity for the parameter of the physical activity signal which is used to adapt the stimulatin intensity. Reducing the sensitivity ensues dependent on the time over which the stimulation intensity is below a defined threshold. A method for operating the device is also disclosed.
