Abstract

The invention relates to a pain sensitivity evaluation system based on multi-dimensional measurement. The pain sensitivity evaluation system comprises an acquisition module, a control module, a collecting module, an electrical stimulation module, a processing module, a pain evaluation module and a pain evaluation integration module, wherein the acquisition module acquires user information and creates a user database for a user to input basic information; the control module integrates and controls the electrical stimulation module and the audio acquisition module, the electrical stimulation module gives pain stimulation to a user according to parameters such as current intensity and pulse width, and the acquisition module acquires electroencephalogram signals and audio signals; the processing module processes the collected electroencephalogram signals and audio signals to obtain a processing result; a stimulation-response model module carries out analysis on the obtained result and establishes a personalized stimulation-response model; and the pain evaluation integration module integrates questionnaire evaluation and stimulation-response model data and calculates individual pain sensitivity scores.

Description

technical field [0001] The present invention relates to the field of pain and cognitive neuroscience, and more specifically, to a pain sensitivity assessment system and method based on multidimensional measurement. Background technique [0002] Pain is a complex subjective experience, which not only reflects the nociceptive nerve impulse transmitted by the sensory system, but also is affected by various psychological and social factors. This leads to different individuals showing different pain perception thresholds and tolerance thresholds, or different pain perceptions for the same physical stimulus or clinical disease, that is, individual differences in pain sensitivity. Previous studies have shown that individual differences in pain sensitivity can not only significantly affect their pain perception, but also affect the timely diagnosis and treatment of diseases, as well as the development of chronic pain symptoms. Therefore, it is particularly important to accurately a...
