Abstract
Background : Although actigraphy has been used to evaluated sleep-wake patterns and quality of sleep disorders patients, its usefulness in obstructive sleep apnea syndrome (OSAS) and primary insomnia is unclear. To investigate the value of actigraphy in OSAS and differentiating OSAS from primary insomnia, night polysomnography (PSG) and actigraphy were performed simultaneously. Methods : 31 OSAS patients and 21 primary insomnia patients were included (16 females, 36 males). Sleep latency, total sleep time, sleep efficiency and actual wake time, movement and fragmentation index (MFI) were obtained in actigraphy and compared with PSG results. Spearmann correlation analysis and Mann-Whitney U test were used. Results : The sleep efficiency and total sleep time are highly correlated in PSG and actigraphy (p0.05). OSAS had a significantly higher movement and fragmentation index (MFI) than that of primary insomnia (p
