The term “economy class syndrome” described a potentially serious condition that could occur due to prolonged immobility in a cramped position. It refers to the formation of blood clots in the deep vein systems of the calf area, where in some instance; the clot may get dislodged from the vein, and travels through the blood system and eventually get lodged in more likely, the lung.
The latter stage is associated with incidence of sudden death. But the clots that remain in the vein of the calf area are not to be taken lightly either, as it could bring serious tissue damage, skin lesions, ulceration, and possible requirement for limb removal.
To prevent this condition, passengers on a long-haul flight are encouraged to do leg exercises from time to time while seated, i.e. bending and extending, and rotation of ankles to promote circulation in the lower legs. But cramped leg space area in the Economy Class restricts such movement, and hand luggage stowed under seats, add further to the restriction. On the other hand, many airlines discourage unnecessary walk in the cabin for safety reason.
A small and simple device that can be used by airplane travelers to exercise their calf muscles and encourage blood circulation while in their seated position was developed by Professor Dr Pan Kok Long of the Faculty of Medical and Health Sciences, Universiti Malaysia Sarawak.
A patent filing for utility innovation has been granted.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
