   A new Israeli-developed airline seat that allows air travelers to move their legs more freely during a flight could reduce the risk of deep vein thrombosis (DVT) in air travelers according to a new study.
The research by Dr. Harry Abramowitz and Prof. David Gertz, both from the Department of Surgery and the Vascular Surgery Unit of Shaare Zedek Medical Center in Jerusalem, shows that of 25 volunteers who tested the modified seat, NewSit, developed by Israeli entrepreneur Arnold Jonas, 23 saw improvements in their leg volume after using the seat.
The volunteers, aged between 21 to 61, were asked to sit on a normal airline seat continuously for five hours. Air plethysmography (APG) was used to measure the venous volume of their leg calves both before and after the test. A week later the same experiment was carried out on the modified seat.
"The mean percent increase in venous volume for the conventional seat after five hours of continuous sitting was significantly greater than that of the modified seat," the report, published in the Annals of Vascular Surgery, stated.
"These are extremely promising results," Jonas told ISRAEL21c, speaking from Orange County in California. "After sitting ...   more »
