We describe a computer-based interview system for patients with back pain. The system uses a light-pen for the patient--computer interface. The questionnaire consists of over 200 multiple and single choice questions. Graphic presentations are used to identify pain patterns. The procedure has been well accepted by patients and is in routine clinical use in several hospitals.
