This is not CCSVI research, it's astronaut research (but not on astronauts, on normal volunteers). It would be the worst thing for any of us...sixty days in a downwardly tilted bed!!After the first 11-15-day period, participants will spend 60 days lying in bed, (except for limited times for specific tests) with their body slightly tilted downward (head down, feet up). Every day, they will be awake for 16 hours and lights out (asleep) for 8 hours. During the bed rest time they will also take part in a number of tests to find out changes in the state of their bone, muscle, heart and circulatory system, and nervous system, as well as their nutritional condition and their ability to fight off infections.”

Will they get a MRI after the experiment?Cece wrote:www.thepennyhoarder.com/2011/02/nasa-wi ... tay-in-bed

This astronaut study seems like an approximation of what we experience in terms of outflow obstructions? I don't know if it would affect their brains in just 60 days. But it does not seem like a healthy thing to do. How do the researchers sleep at night....
The increase in CSA in the jugulars is because of reduced outflow due to the head-downward tilt.Head‐down tilt is often used to improve cannulation of the IJV. Jugular diameter or CSA in adults increases on ultrasound, with varying degrees of tilt. Armstrong and colleagues demonstrated a rising lateral IJV diameter with 10, 20 and 30° of head‐down tilt, the greatest change (+14%) occurring between the supine and the 10° tilt position.2 In 15 patients during anaesthesia, mean right jugular CSA of 160 (86) mm2 when supine increased to 213 (112) mm2 with 10° tilt (relative increase +25%).6 CSA increased by 37% (from 118 to 162 mm2 during head‐down tilt) in ICU patients.3 Our finding of an approximately 36% increase therefore supports the data previously published.
