Automated calibration of posture state classification for a medical device

A method for controlling a medical device, comprising:

• associating, via a processor, a first posture state with at least one therapy parameter value;
• sensing, via a posture state sensor, a first physiological signal indicative of posture state of a patient;
• sensing, via a second sensor, a second physiological signal indicative of an electrical signal originating from the patient;
• and
• delivering, via a therapy delivery module, therapy to the patient according to the at least one therapy parameter value when the patient is determined to be in the associated posture state based on the first physiological signal,
• wherein associating, via the processor, the posture state with the at least one therapy parameter value is based, at least in part, on the second physiological signal.

A medical system, comprising:

• a memory configured to store an association between a posture state and at least one therapy parameter value;
• a posture state sensor configured to sense a first physiological signal indicative of at least one of activity and posture of the patient;
• a second sensor configured to sense a second physiological signal indicative of electrical activity sensed from tissue of the patient;
• and
• one or more processors configured to control delivery of therapy to the patient according to the at least one therapy parameter value when the patient is determined to be in the posture state based on the first physiological signal, and wherein the association between the posture state and the at least one therapy parameter value is formed based, at least in part, on the second physiological signal.

A medical device, comprising:

• a memory configured to store one or more posture state definitions, each indicating a posture state and at least one therapy parameter value used to control delivery of therapy to a patient when the patient is determined to be in the posture state;
• a posture state sensor configured to sense a first physiological signal indicative of a posture state of the patient;
• a second sensor configured to sense a second physiological signal, wherein the second physiological signal is an electrical signal originating from tissue of the patient;
• and
• a processor configured to receive the first physiological signal from the posture state sensor, determine the posture state of the patient based on the first physiological signal and the one or more posture state definitions, and control delivery of therapy to the patient according to the at least one therapy parameter associated with the determined posture state of the patient, wherein at least one of the one or more posture state definitions is stored, based at least in part, on the second physiological signal.

A medical system, comprising:

• memory means for storing one or more posture state definitions, each indicating a posture state and at least one therapy parameter value used to control delivery of therapy to a patient when the patient is determined to be in the posture state;
• posture state sensor means for sensing a first physiological signal indicative of a posture state of the patient;
• second sensor means for sensing a second physiological signal, wherein the second physiological signal is an electrical signal originating from tissue of the patient;
• and
• processing means for receiving the first physiological signal from the posture state sensing means, for determining the posture state of the patient based on the first physiological signal and the one or more posture state definitions, and for controlling delivery of therapy to the patient according to the at least one therapy parameter associated with the determined posture state of the patient, wherein at least one of the one or more posture state definitions is stored, based at least in part, on the second physiological signal.
