BACKGROUND AND PURPOSE Micro-arousals (MA) are commonly considered as sleep components reflecting sleep fragmentation. However, their elucidation is time-consuming, with considerable inter-observer variability. The aim of our study was to investigate the usefulness of a sleep fragmentation index (SFI) to detect sleep disruption in a large sample of patients. PATIENTS AND METHODS Five-hundred ninety-eight polysomnographic studies made in controls and patients were examined. The SFI was… CONTINUE READING
