Detecting sleep to evaluate therapy
First Claim
1. A method for evaluating an efficacy of a movement disorder therapy comprising:
- monitoring at least one physiological parameter of a patient via an implantable medical device that delivers the movement disorder therapy to the patient;
monitoring sleep patterns of the patient with the implantable medical device based on the physiological parameter;
determining sleep quality information based on the sleep patterns; and
presenting the sleep quality information in conjunction with information regarding the delivery of the movement disorder therapy to a user to allow the user to evaluate the efficacy of the movement disorder therapy,wherein the movement disorder therapy delivered by the implantable medical device to the patient treats a movement disorder selected from a group consisting of;
tremor;
Parkinson'"'"'s disease;
multiple sclerosis;
spasticity; and
epilepsy.

Abstract
A system includes one or more sensors and a processor. Each of the sensors generates a signal as a function of at least one physiological parameter of a patient that may discernibly change when the patient is asleep. The processor monitors the physiological parameters, and determines whether the patient is asleep based on the parameters. In some embodiments, the processor determines plurality of sleep metric values, each of which indicates a probability of the patient being asleep, based on each of a plurality of physiological parameters. The processor may average or otherwise combine the plurality of sleep metric values to provide an overall sleep metric value that is compared to a threshold value in order to determine whether the patient is asleep. In addition, an electroencephalogram signal may be used to identify sleep states of the patient.
