Assessment apparatus and assessment method for objective pain assessment

An assessment apparatus and method for objective pain assessment are provided, wherein the apparatus includes a processor comprising a frequency-domain transformation module, a frequency-band segmentation module, a first assessment submodule, and a second assessment submodule. The frequency-domain transformation module generates a global time-frequency feature matrix, which is segmented by the frequency-band segmentation module in a frequency domain into five frequency bands associated with pain perception. The first assessment submodule extracts last time step features and an adjacency matrix from the time-frequency feature matrix and generates a first feature vector representing global association patterns among electrodes used for acquiring EEG signals. The second assessment submodule generates a second feature vector with local spatiotemporal dynamic features of EEG signals, concatenates it with the first feature vector to form a fused feature vector, computes its class probability distribution, normalizes it, and generates an objective pain quantification indicator corresponding to the EEG signals.

Visual synthesis-based virtual or augmented reality pain treatment apparatus and device

A visual synthesis-based virtual or augmented reality pain treatment apparatus and device. In the apparatus, an interaction control unit generates a pain stimulation scheme matching a current patient to be treated and sends the pain stimulation scheme to a data processing unit. The data processing unit, on the basis of the received pain stimulation scheme, generates a virtual reality environment and a virtual stimulation source visible to the patient in the virtual reality environment. A display unit displays the virtual reality environment and the virtual stimulation source to said patient. The data processing unit, on the basis of a pain category to be induced, determines a stimulation target of a limb and parameters of the virtual stimulation source. The display unit drives the virtual stimulation source to implement a visual approaching motion to the stimulation target of the patient so as to achieve non-real stimulation. The somatosensory system of the patient is activated by means of a vision-nerve coupling mechanism to induce the patient to feel a tactile sensation, a thermal sensation, and / or a cold sensation at the stimulation target and in a nearby area thereof, thereby achieving neuromodulation therapy of a pain pathway.

Method and system for pain state discrimination based on specific neural circuit activity patterns

PendingCN122320456AAchieve precise targetingRealize functionPain.statusAcute stage
A method and system for differentiating acute and chronic pain based on the functional state of specific neural circuits is proposed. This method utilizes in vivo two-photon / endoscopic calcium imaging and ex vivo brain slice patch-clamp techniques to longitudinally monitor the activity dynamics of neurons in the DRN and ZI brain regions during the acute and chronic phases of a neuropathic pain model. By extracting and analyzing calcium and electrophysiological signal parameter sets, distinguishing criteria are established: if the activity of 5-HTergic neurons in the DRN is specifically enhanced in the acute phase, the indication is acute pain; if the activity of GABAergic neurons in the ZI is specifically enhanced in the chronic phase, the indication is chronic pain. This invention achieves an objective and precise differentiation of the transition from acute to chronic pain at the level of specific neural circuits, providing a new strategy and tool for pain mechanism research and clinical diagnosis and treatment.
