This PLMs database was collected during the DREAMS project, to tune, train and test our automatic detection algorithms.

It consist of 10 whole-night PSG recordings coming from patients, in which one of the two tibialis EMG was annoted in periodic limb movements (PLMs) by an experts.

In order to facilitate future research and performance comparision, we decided to publish these data on Internet.

Database description

Data collected were acquired in a sleep laboratory of a belgium hospital using a digital 32-channel polygraph (BrainnetTM System of MEDATEC, Brussels, Belgium). They consist of 10 whole-night polysomnographic recordings coming from patients with Periodic limb movement disorder. Two EOG channels (P8-A1, P18-A1), three EEG channels (CZ-A1 or C3-A1, FP1-A1 and O1-A1), one submental EMG channel and two EMG of the anterior tibialis muscle were recorded. The standard European Data Format (EDF) was used for storing. The sampling frequency was 200Hz or 50Hz. On each of these recordings, all leg movements of one of the two tibialis EMG were annoted by an expert. The criteria used were those of the American Sleep Disorder Association (ASDA), Without taking into account the periodic aspect and the distinction between awaking movement or not. The recordings were also previously scored in sleep stages according to the Rechtschaffen and Kales criteria, but no note of these stages cotations was given to the scorer during the PLMS annotation.
