Low motor activity levels and prolonged episodes of uninterrupted immobility are characteristics of sleep. In clinical practice, the use of polysomnographic (PSG) recording is a standard procedure to assess sleep. However, PSG is not suitable for long-term monitoring in the home environment. This paper describes the development of a portable telemonitoring device that detects movements of a subject by conductive mats, and evaluates sleep stages via physical activity data. The device itself also…

Results show that sleep posture and posture change can be precisely detected via tri-axis accelerometer information, and there is no significant difference within subject data sets, but there are statistically significant differences among subjects, both for heart rate and for sleep posture distribution.

An algorithm was developed to process real-time tri-axial acceleration signals produced by human movement to identify targeted still postures, postural transitions, and dynamic movements and high identification accuracy was obtained in performance evaluation.

Gaussian model for movement detection during Sleep

A method for detection of movement in bed that is evaluated on data collected from patients admitted for regular polysomnography, based on load cells installed at the supports of a bed, achieves an overall sensitivity of 97.9% and specificity of 98.7%.

Monitoring Sleep with Force Sensor Measurement

This thesis presents methods for comfortable sleep measurement at home that are based on measuring the body with practically unnoticeable force sensors installed in the bed, so those physiological parameters can be measured.

Development of a Bed-Centered Telehealth System Based on a Motion-Sensing Mattress

A Bed-Centered Telehealth System (BCTS), which uses the bed as the center of health data collection of telehealth systems implemented in homes and nursing homes, and the core sensor is a soft motion-sensing mattress, Whiz PAD.

Unobtrusive Movement Detection during Sleep based on Load Cell Dynamics

Changes in the pattern of motor activities during sleep can be a disease marker, or can reflect various abnormal physiological and neurological conditions. Currently, there are no unobtrusive ways to

A method for classification of movements in bed

The unobtrusive aspect of this approach is particularly valuable for longer-term home monitoring against a standard clinical setting and the movement classification system is evaluated on data collected in the laboratory, and it classified correctly 84.6% of movements.

A load-cell based in-bed body motion detection and classification system

A low-cost, low-overhead, and highly robust system for in-bed movement detection and classification that uses low-end load cells that can effectively extract body movement signals from load cell data that is collected through log-Peak, energy-peak, and ZeroX-Valley.

Actigraphy substantially underestimated leg electromyographic activity and therefore could not be used routinely for diagnostic purposes, and because error scoring did not undergo significant changes across the two nights, actigraphy may be used for follow-up evaluation.
