Self-adaptive system for the automatic detection of discomfort and the automatic generation of SCS therapies for chronic pain control
First Claim
1. A method for treating a patient with chronic pain, the method comprising:
- providing signals to at least one lead implanted in a patient, the signals based on sets of stimulation parameters, the lead delivering the signals to nerves and tissue of the dorsolateral spinal cord of the patient;
continuously monitoring patient parameters by recording sets of physiological measures from the patient;
fusing a set of physiological measures by categorizing each set of physiological measures as one of a plurality of discrete discomfort levels produced by the chronic pain, wherein a discomfort level may include lack of pain;
receiving sets of stimulation parameters selected by the patient;
recording which sets of stimulation parameters are selected by the patient for each discomfort level;
creating a table associating discomfort levels and selected sets of parameters; and
automatically providing signals to the at least one lead based on the table,wherein the stimulation parameters consist of one or more parameters selected from the group consisting of;
contact polarity, signal amplitude, pulse width, and frequency.

Abstract
A system for treating pain consisting of an “add-on” module integrated within the implantable pulse generator (IPG) component of IPG spinal cord stimulators, or, alternatively, integrated within the radiofrequency (RF) transmitter component of RF spinal cord stimulators. The system automatically and continuously monitors, measures, and classifies multiple patient physiological parameters without human intervention. The system also classifies qualitative perceptive changes felt by the patient. On the basis of this input vector information, the system automatically and continuously generates the most appropriate stimulation programs to improve, alleviate, or eliminate the patient'"'"'s pain without human intervention. The system automatically and continuously adapts itself to both quantitative physiological changes within the patient and qualitative perceptive changes felt by the patient.
