A method for determining an objective pain score for pain experienced by a patient includes placing adhesive bandages on a patient, each of which has multiplexed sensors and providing information from the sensors to a scoring agent that has been trained through contrastive learning to provide the objective pain score based on the information from the sensors.

Methods and systems are provided for diagnosing chronic spinal pain of a patient that include receiving and storing an image of the patient's back or neck. The image includes a first set of visual indicia corresponding to anatomical landmarks of the patient's back or neck as well as a second set of visual indica corresponding to locus of pain experienced by the patient. The image is processed to generate feature data representing spatial location and pain characteristics of point(s) corresponding to locus of pain experienced by the patient. The feature data is input to an expert system that generates first output data representing a predicted diagnosis of chronic pain of the patient and optional second output data representing a confidence level associated with the predicted diagnosis as indicated by the feature data input. A lookup table provides a treatment corresponding to the first output data and the optional second output data.

The present invention relates to a medical device developed to reduce pain during local anesthesia and injection procedures. The device is equipped with circularly arranged vibration motors, a cold application surface, and a controlled pressure mechanism. The simultaneous application of vibration, pressure, and cold stimulation prevents or delays the transmission of pain signals to the brain, thereby reducing pain experienced by the patient during the injection.

Systems and techniques are disclosed to establish programming of an implantable electrical neurostimulation device for treating chronic pain of a human subject, through the use of a dynamic model adapted to determine pain treatment parameters for a human patient and identify a new device operational program to implement the pain treatment parameters to address the chronic pain condition. In an example, the system to establish programming of the neurostimulation device performs operations that: obtain state data indicating a measured value that is correlated to pain experienced by the human subject; determine neurostimulation programming parameters, using a dynamic model, for pain treatment in the human subject, as the dynamic model is used to identify values of the neurostimulation programming parameters that predict an improvement to the measured value; and indicate a neurostimulation program for the neurostimulation device, that includes the neurostimulation programming parameters for the implantable electrical neurostimulation device.

This invention discloses a personalized biofeedback analgesia system in a virtual reality environment, relating to the technical field of pain regulation. It includes a personalized feedback scenario generation module, which collects the test subject's pain experience data to form a desired scenario video resource library; a personalized pain biomarker mining module, which collects multimodal bioelectrical signals and corresponding pain questionnaires from patients in different states to identify individual-specific pain biomarkers; an online pain monitoring module, which acquires the patient's current multimodal bioelectrical signals in real time, extracts pain biomarker response values, compares them with preset pain thresholds, and outputs a pain warning signal; and a pain intervention module, which, upon receiving the pain warning signal, matches and recommends personalized scenario videos generated based on the patient's characteristics from the desired scenario video resource library, and uses virtual reality to visually present the changes of corresponding regulatory elements in the recommended scenario videos in real time to alleviate pain. This invention has a more comprehensive data foundation, can meet the individual needs of patients, and reminds patients to take pain intervention measures when the pain signal is weak, achieving effective prevention and relief of pain.

Provided are a pain measuring device and a main measuring method. More particularly, the pain measuring device may control a temperature provided from a temperature stimulator, receive, from a user input portion, a user input for recording a level of stimulation according to the temperature, obtain, from a camera, image data representing a change in an external shape of a user according to the stimulation, obtain, from a sensor, biodata representing a biological change of the user according to the stimulation, and obtain information about a level of pain experienced by the user according to the stimulation based on data corresponding to the user input, the image data, and the biodata.
