POSTURE STATE RESPONSIVE THERAPY DELIVERY USING DWELL TIMES
First Claim
1. A medical device system, comprising:
- a sensor that senses at least one signal indicative of a posture state of a living body;
posture state detection logic that classifies the living body as being in a posture state based on the at least one signal and that determines whether the living body is classified in the posture state for at least a predetermined period of time; and
response logic that initiates a response as a result of the living body being classified in the posture state only after the living body has maintained the classified posture state for at least the predetermined period of time.

Abstract
Techniques related to classifying a posture state of a living body are disclosed. One aspect relates to sensing at least one signal indicative of a posture state of a living body. Posture state detection logic classifies the living body as being in a posture state based on the at least one signal, wherein this classification may take into account at least one of posture and activity state of the living body. The posture state detection logic further determines whether the living body is classified in the posture state for at least a predetermined period of time. Response logic is described that initiates a response as a result of the body being classified in the posture state only after the living body has maintained the classified posture state for at least the predetermined period of time. This response may involve a change in therapy, such as neurostimulation therapy, that is delivered to the living body.

20. A medical system to provide therapy to a living body, comprising:
-
a sensor; posture state detection logic to receive at least one signal from the sensor and to employ the at least one signal to classify a posture state of the living body; a therapy module to control the therapy provided to the living body based on the classification; and a programmer to program the posture state detection logic to determine whether, after the living body is classified in a posture state, the living body maintains the posture state for a predetermined period of time, and if so, the posture state detection logic to provide an indication to allow the therapy module to adjust the therapy in response to the posture state, and otherwise, to allow the therapy to remain unchanged. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)

33. A method, comprising:
-
receiving at least one signal from a sensor; classifying a living body as being in any of multiple defined posture states based on the at least one signal; and determining whether the living body is classified as remaining in a posture state for a predetermined period of time, and if so, automatically initiating via a response module a response that is determined based on the posture state. - View Dependent Claims (34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
