Randomized Controlled Trial Clinical Trial
Effects of a mandibular repositioning appliance on sleep structure, morning behavior and clinical symptomatology in patients with snoring and sleep-disordered breathing.
Mandibular repositioning appliances (MRAs) have become an established treatment for snoring and sleep-disordered breathing - though most studies only focused on the evaluation of respiratory variables. ⋯ Apart from its good therapeutic effects on snoring and respiratory variables (snoring showed complete or partial response in 68%, the apnea-hypopnea index in 67% of the apnea patients), the MRA also improved psychopathology, objective and subjective sleep and awakening quality.

One of the core symptoms of the chronic fatigue syndrome (CFS) is unrefreshing sleep and a subjective sensation of poor sleep quality. Whether this perception can be expressed, in a standardized questionnaire as the Pittsburgh Sleep Quality Index (PSQI), has to our knowledge never been documented in CFS. Furthermore, correlations of subjective fatigue, PSQI, affective symptoms and objective parameters such as sleep efficiency are poorly described in the literature. ⋯ Our findings indicate that a sleep quality misperception exists in CFS or that potential nocturnal neurophysiological disturbances involved in the nonrecovering sensation in CFS are not expressed by sleep variables such as the SEI or sleep stage distributions and proportions.
