Monitoring of Cardiorespiratory Parameters during Sleep Using a Special Holder for the Accelerometer Sensor

Sensors, 2023
Sleep is extremely important for physical and mental health. Although polysomnography is an established approach in sleep analysis, it is quite intrusive and expensive.

Neurotechnological solutions for post‐traumatic stress disorder: A perspective review and concept proposal

Healthcare Technology Letters, Volume 10, Issue 6, Page 133-138, December 2023., 2023
Abstract Post‐traumatic stress disorder (PTSD) is an anxiety condition caused by exposure to severe trauma. It is characterised by nightmares, flashbacks, hyper‐vigilance and avoidance behaviour. These all lead to impaired functioning reducing quality of life. PTSD affects 2–5% of the population globally.

Cardiovascular function and ballistocardiogram: a relationship interpreted via mathematical modeling [PDF]

, 2019
Objective: to develop quantitative methods for the clinical interpretation of the ballistocardiogram (BCG). Methods: a closed-loop mathematical model of the cardiovascular system is proposed to theoretically simulate the mechanisms generating the BCG ...

Sleep–wake monitoring of people with intellectual disability: Examining the agreement of EMFIT QS and actigraphy

Journal of Applied Research in Intellectual Disabilities, Volume 36, Issue 6, Page 1276-1287, November 2023., 2023
Abstract Background Gaining insight into sleep–wake patterns of persons with intellectual disabilities is commonly done using wrist actigraphy. For some people, contactless alternatives are needed. This study compares a contactless bed sensor with wrist actigraphy to monitor sleep–wake patterns of people with moderate to profound intellectual ...

Performance Evaluation of a Smart Bed Technology against Polysomnography

Sensors, 2022
The Sleep Number smart bed uses embedded ballistocardiography, together with network connectivity, signal processing, and machine learning, to detect heart rate (HR), breathing rate (BR), and sleep vs. wake states. This study evaluated the performance of

On‐Desk Model‐Based Study for Evaluating the Effect of Squeezing the Arteries in the Forearm on the Bioimpedance and Pressure of Blood

Journal of Sensors, Volume 2023, Issue 1, 2023., 2023
Background. Today, central aortic pressure (CAP) is measured through the invasive procedure of angiography. The only feasible alternative is applanation tonometry, requiring experienced staff to perform reliable measurements. The method of measuring the electrical bioimpedance (EBI) from the wrist gives promising results in estimating the CAP. However,

Vision-Based Measurement of Heart Rate from Ballistocardiographic Head Movements Using Unsupervised Clustering

Sensors, 2019
Heart rate has been measured comfortably using a camera without the skin-contact by the development of vision-based measurement. Despite the potential of the vision-based measurement, it has still presented limited ability due to the noise of ...

Sleep monitoring challenges in patients with neurocognitive disorders: A cross‐sectional analysis of missing data from activity trackers

Health Science Reports, Volume 5, Issue 3, May 2022., 2022
Abstract Background and Aims Activity monitors, such as Fitbits®, are being used increasingly for research purposes and data have been validated in healthy community‐dwelling older adults. Given the lack of research in older adults with neurocognitive disorders, we investigated the consistency of sleep data recorded from a wrist‐worn activity monitor ...

Ballistocardiography [PDF]

Academic Medicine, 1953
A physical analysis is presented of the Starr, Nickerson, and Dock methods for registering the ballistocardiogram. It is shown that many forms of distortion are present. Some of the distortion may be present in the instrumentation which may be controlled, and other forms of distortion are inherent in the subject under test which are most difficult to ...
