The sleep analysis and scoring program WSCORE was developed under the European Neurological Network (ENN) project. The purpose was to implement an analysis and scoring system for ambulatory and standard polysomnography. In addition to visual Rechtschaffen & Kales scoring the program offers a possibility of free form visual scoring. It contains also analysis modules for Periodic Leg Movement Disorder, Hjort parameters, heart rate and EMG amplitude. A FTP client module was built into the program so that it can be used as a telemedicine application.
