However, without the guidance of a specialist, the patient, who has no medical or technical training, has to place the sensors in the correct positions. There are many home sleep recording systems on the market which aim to reduce the financial cost per patient and reach a larger population by reducing the number of parameters recorded. However, PSGs are expensive and are limited by the number of beds available in the study centre and the number of specialists available to read the data. 2012).Ĭurrently, the gold standard in terms of sleep disorder diagnosis is a sleep study, or an overnight polysomnogram (PSG). Moreover, poor sleep affects one’s mental status, leading to poor mental function, reduced compliance which compounds chronic disease treatment, and exacerbates mental conditions such as depression and schizophrenia ( Cho et al. ![]() Daytime sleepiness is the cause of hundreds of road traffic accidents, and has even been linked to catastrophes such as Chernobyl ( Hossain & Shapiro 2002). In fact, the health effects of sleep disorders span a wide range: from the apparently simple daytime sleepiness, which is a non-specific symptom common to other disorders ( Pagel 2009), to the more severe effects of increased risk of cardiovascular disease and stroke ( Young et al. It is difficult to quantify the impact of poor sleep structure in a broad sense as it is often considered a symptom of other diseases, although it is intricately connected to many of the dominant burdens of disease ( Üstün et al. Up to 40% of the United States (US) adult population experience problems with falling asleep or daytime sleepiness, which are largely assumed to be due to disturbed sleep patterns ( Hossain & Shapiro 2002). The effects of sleep disorders are extensive, impacting sufferers physically, psychologically and financially. Results: The computational results demonstrated that the algorithm we developed can accurately classify certain types of daily activities, with high overall classification accuracy for both waist-worn GENEA (0.99) and wrist-worn GENEA (right wrist = 0.97, left wrist = 0.96).The International Classification of Sleep Disorders (ICSD) has identified over 80 different sleep disorders, all of which have associated treatments ( Thorpy 1990, AASM 2005). Features obtained from both fast Fourier transform and wavelet decomposition were extracted, and machine learning algorithms were used to classify four types of daily activities including sedentary, household, walking, and running activities. Acceleration data were collected at 80 Hz. Throughout, three GENEA accelerometers were worn: one at the waist, one on the left wrist, and one on the right wrist. m-2) completed an ordered series of 10�12 semistructured activities in the laboratory and outdoor environment.Methods: Sixty participants (age = 49.4 ± 6.5 yr, body mass index = 24.6 ± 3.4 kg The purpose of this study was to develop methods to classify physical activities into walking, running, household, or sedentary activities based on raw acceleration data from the GENEA (Gravity Estimator of Normal Everyday Activity) and compare classification accuracy from a wrist-worn GENEA with a waist-worn GENEA. Output is in arbitrary counts that can be classified by activity intensity according to published thresholds. Introduction: Most accelerometer-based activity monitors are worn on the waist or lower back for assessment of habitual physical activity.
