Abstract
Sleep is completely regarded as obligatory component for an individual’s prosperity and is an extremely important element for the overall mental and physical well-being of an individual. It is a condition in which physical and mental health of an individual are in condition of halt. The conception of sleep is considered extremely peculiar and is a topic of discussion and it has attracted the researchers all over the world. Proper analysis of sleep scoring system and its different stages gives clinical information when diagnosing on patients having sleep disorders. Since, manual sleep stage classification is a hectic process as it takes sufficient time for sleep experts to perform data analysis. Besides, mistakes and irregularities in between classification of same data can be recurrent. Therefore, there is a great use of automatic scoring system to support reliable classification. The proposed work provides an insight to use the automatic scheme which is based on real time EMG signals. EMG is an electro neurological diagnostic tool which evaluates and records the electrical activity generated by muscle cells. The sleep scoring analysis can be applied by recording Electroencephalogram (EEG), Electromyogram (EMG), and Electrooculogram (EOG) based on epoch which is defined as a period of 30 second length segments, and this method of sleep scoring system is also called polysomnography test or PSG test. The standard database of EMG signals was collected from different hospitals in sleep laboratory which gives the different stages of sleep. These are Waking, Non-REM1 (stage-1), Non-REM2 (stage-2), Non-REM3 (stage-3), REM. The main motive of the proposed work is the synchronization of EEG, EMG, EOG in order to understand different stages of sleep when they are simultaneously recorded. The procedure can be useful in clinics, particularly for scientists in studying the wakefulness and sleep stage correlation and thus helps in diagnosing some sleep disorders.
Highlights
Polysomnography test (PSG) test is the conduction of various physiological signals like EOG (Electrooccularogam), EMG (Electromyogram), EEG (Electroencephalograph) which when recorded only for a short period of time known as epoch and analyzed gives us different stages of sleep [3], [4]
The normal sleep classification depends on the epochs which are scored as wakefulness, Rapid Eye Movement (REM), NonRapid Eye Movement (NREM)
There are so many peoples who are experiencing such sleep disorders which affect their day to day life
Summary
Sleep is an important aspect for person’s good health and is appraised as an essential element for both physical and mental ability of an individual. Sleep is virtual detachment of a human being from his surroundings. It is a condition in which both physical and mental functions of a human being are in a state of halt. Long time sleep insufficiency or sleep disorders prompts various diseases of kidney, heart, etc and enlarges the possibility of diseases like diabetes, high blood pressure as well as strokes. These diseases are called as passive diseases. Automatic sleep scoring system has been undertaken by the visual investigation of polysomnograms (PSG). PSG test is the conduction of various physiological signals like EOG (Electrooccularogam), EMG (Electromyogram), EEG (Electroencephalograph) which when recorded only for a short period of time known as epoch and analyzed gives us different stages of sleep [3], [4]
