Myths and Methodologies: Understanding the health impact of head down bedrest for the benefit of older adults and astronauts. Study protocol of the Canadian Bedrest Study

Experimental Physiology, Volume 109, Issue 5, Page 812-827, 1 May 2024.
Abstract Weightlessness during spaceflight can harm various bodily systems, including bone density, muscle mass, strength and cognitive functions. Exercise appears to somewhat counteract these effects. A terrestrial model for this is head‐down bedrest (HDBR), simulating gravity loss. This mirrors challenges faced by older adults in extended bedrest and

Challenges in Using Seismocardiography for Blood Pressure Monitoring

Computing in Cardiology Conference (CinC), 2017
The capability of continuously and non-invasive blood pressure (BP) monitoring is valuable in the clinical setting. Pulse transit time (PTT) has shown the promise to track changes in the arterial BP. This study examines the efficacy of seismocardiogram (SCG) and photoplethysmogram (PPG) combination for timing the proximal and distal pulse respectively ...
