Detection of fast eye movement (REM) sleep and associated abnormalities is important for identifying various nervous system diseases. The present disclosure relates to the detection of time intervals during which a subject is in REM sleep by utilizing electroencephalogram (EEG) data from selective spectral frequencies. The techniques as disclosed herein may use one or more EEG electrodes, and more particularly, single channel EEG signals provide a simple and cost-effective solution. The disclosed techniques may pre-process the EEG data, extract features and / or derived features for one or more time intervals from selective spectral bands (e.g., delta and gamma). These extracted features may be normalized and clustered to further determine REM, non-REM, and waking time intervals. By using one or more non-EEG sensors to detect the presence of muscular tension of the identified REM sleep intervals, and by performing sleep pattern analysis, potential REM intervals can be verified to detect REM behavioral disorders.

A muscle tension evaluation device includes a pedal, a front force sensor arranged at a front end of the pedal, a rear force sensor arranged at a rear end of the pedal, and a judgment unit connected to the front and rear force sensors. The judgment unit obtains a front force standard deviation, a rear force standard deviation, a front force deviation, and a rear force deviation from sensing results. A first threshold value and a second threshold value are obtained from the front and rear force standard deviations. The front and rear force standard deviations are standard deviations of front and rear force signals in a first time interval. The front and rear force deviations represent degrees of deviation of the front and rear force signals in a second time interval relative to the first time interval. When the front force deviation is greater than the first threshold value and the rear force deviation is greater than the second threshold value, it indicates that the muscle is in a high tension state. In addition, the present application also provides a muscle tension evaluation method.
