  • Patent number: 11904170
    Abstract: A system for selecting a sensitivity level for adjusting an intensity setting for therapy provided to a patient includes one or more processors and one or more processors coupled to the memory. The one or more processors are configured to receive an indication of an input to adjust an intensity setting related to the therapy provided to the patient and determine a sensitivity level for adjustment of the intensity setting based on an efficacy of the therapy provided to the patient. The one or more processors are further configured to determine an updated intensity level for the intensity setting based on the sensitivity level and the input to adjust the intensity setting and output an instruction to cause a medical device to provide the therapy at the updated intensity level.
