Abstract
Methods and systems for delivering a therapy and observing one or more metrics of autonomic function. Spinal cord stimulation may be initiated, and patient response monitored using one or more metrics of autonomic function, including heart rate, heart rate variability, or other markers. Therapy intensity may be increased or decreased, or therapy may be changed to use a different program, or therapy may be ceased, depending on changes in the observed metrics of autonomic function.
Claims20
A method of treating a patient having an implantable medical device system including a lead adapted for placement in the spinal column of a patient and a housing containing each of a sensing circuitry configured to sense a metric of the patient's autonomic function, and a stimulation circuitry configured to issue pulses via the lead;
- the method comprising:
- issuing pulses to the patient in accordance with a first treatment program;
- determining, from the sensing circuitry, whether the metric of the patient's autonomic function indicates a risk of overregulation;
- and
- in response to a determination that the metric of the patient's autonomic function indicates a risk of overregulation, reducing the risk of overregulation.
A method of treating a patient using a spinal cord stimulator, comprising:
- generating a mapping of autonomic status of the patient using a first metric and a second metric, the mapping including a first region for a stressed status, and a second region for a relaxed status;
- initiating therapy using a first therapy program;
- confirming, by tracking the first metric and the second metric, that the patient's autonomic status has shifted from the first region to the second region in response to initiating therapy using the first therapy program;
- monitoring the patient's autonomic status in the second region as therapy continues using the first therapy program;
- determining that the patient's autonomic status has left the second region;
- in response to the determining that the patient's autonomic status has left the second region, determining that the patient is overregulated.
