Abstract
An affective system, apparatus and method to analyze pain level states using affective and physiological data collection to determine pain and pain levels in a patient. The system and apparatus includes video cameras to record patient facial or body expressions and movements and combines the recorded expressions and movements with physiological data to determine pain level states in the patient.
Claims23
A method for diagnosing pain state levels comprising the operations of:
- collecting affective data including facial expressions;
- collecting physiological measurement data;
- analyzing collected affective and physiological data to determine pain state levels;
- and
- communicating the pain state level information.
The diagnostic system of claim 8 wherein the at least one physiological sensor includes a device for measuring analytes from at least one biomarker selected from sweat, saliva and blood.
A diagnostic system for diagnosing a pain state level in a patient comprising:
- at least one image capture device to record one or more facial data of the patient;
- the facial data including one or more of:
- facial expressions;
- head, hand or body gestures;
- or body postures;
- at least one physiological sensor associated with the patient to measure physiological data;
- an interactive device in communication with the patient to permit the patient to input quantitative pain data into the diagnostic system;
- a processor to generate a correlated data output from the one or more facial data, the physiological data, and the quantitative pain data, to determine the pain state level in the patient;
- and
- an electronic display to communicate the determined patient pain state level to a health care provider and/or to the patient.
A pain level diagnostic apparatus comprising:
- a video screen viewed by a patient;
- the video screen including an interactive pain assessment questionnaire;
- at least one image capture device associated with the pain level diagnostic apparatus, the at least one image capture device positioned so as to be not visible to the patient and generating one or more facial data of the patient;
- the facial data including one or more of:
- facial expressions;
- head, hand or body gestures;
- or body postures;
- one or more physiological sensors associated with the patient to generate physiological data;
- and
- a controller associated with the pain level diagnostic apparatus to record and analyze the one or more facial data and the physiological data and to correlate the recorded and analyzed data with a quantitative pain data input by the patient on the interactive pain assessment questionnaire to determine a pain state level of the patient;
- whereby the determined pain state level may be communicated to a health care provider and/or to the patient.
