Abstract: Disclosed is a system for pain diagnosis, comprising an input module (10) for receiving inputs of pain areas of a patient onto a three-dimensional human body model, a diagnosis module (20) for deriving diagnosis results, comprising a database (22) for storing data on common pain patterns, a submodule A (21) for checking over a surface of the human body model, comparing the inputted pain areas with respect to the model, and deriving referred pain patterns, a submodule B (23) for allowing the patient to confirm symptoms of the derived pain patterns and assigning weighted values to confirmed pain patterns, a submodule C (24) for comparing images of the confirmed pain patterns with the inputted pain areas, and a submodule D (25) for calculating degrees of matching between the confirmed pain patterns and the inputted pain areas, and an output module (30) for outputting the diagnosis results.
