A systematic comparison of factors that could impact treatment recommendations for patients with Positional Obstructive Sleep Apnea (POSA)

ABSTRACT Objective/Background: Systematically compare four criteria for Positional Obstructive Sleep Apnea (POSA) based on AASM 2007 and 2012 hypopnea scoring definitions. Patients/Methods: 142 records acquired by in-home polysomnography (Sleep Profiler PSG2™) were retrospectively analyzed using AHI based on the American Academy Sleep Medicine 2007 and 2012 criteria (AHI2007 and AHI2012). Positional obstructive sleep apnea (POSA) [...]

Head Position During Sleep: Potential Implications for Patients with Neurodegenerative Disease

Background: The characterization of sleep in those with neurodegenerative disease (NDD) is essential in understanding the potential neurobiological mechanisms that underlie the connection between sleep disruption and NDD manifestations and progression. Objective: Explore the inter-relationships between NDD and age, sex, diagnosis of obstructive sleep apnea, snoring, and duration of sleep time with the head in [...]

Comparison of EMG power during sleep from the submental and frontalis muscles

Objective: Submentalis electromyography (sEMG) and frontalis electromyography (fEMG) muscle activities have been used to assist in the staging of sleep and detection of disruptions in sleep. This study was designed to assess the concordance between sEMG and fEMG power, by and across sleep stages. Methods: Forty-three records with simultaneous acquisition of differential signals from the [...]

Head Position During Sleep Has Potential Implications for Neurodegenerative Disease

FOR IMMEDIATE RELEASE CARLSBAD, Calif.--(BUSINESS WIRE)--Could sleeping on your back increase your brain's risk of developing neurodegenerative disease?  That possibility is revealed in a new study published in the Journal of Alzheimer's Disease. "We compared the in-home sleep patterns of patients with memory impairment resulting from neurodegenerative diseases to a large group of elderly with [...]
