Unlike traditional dress or athletic stockings and socks, compression stockings use stronger elastics to create significant pressure on the legs, ankles and feet. Compression stockings are tightest at the ankles and gradually become less constrictive towards the knees and thighs. By compressing the surface veins, arteries and muscles, the circulating blood is forced through narrower circulatory channels. As a result, the arterial pressure is increased, which causes more blood to return to the heart and less blood to pool in the feet.
There are two types of compression stockings, gradient and anti-embolism.[2]
Anti-Embolism Compression Stockings
These stockings are commonly referred to as TED hose, short for thromboembolism-deterrent hose. They are used to support the venous and lymphatic drainage of the leg.[9]
Like gradient compression stockings, anti-embolism stockings deliver a distributed amount of compression at the ankle and up the leg. This compression, when combined with the muscle pump effect of the calf, aids in circulating blood and lymph fluid through the legs (in non-ambulatory patients).
Compression wear has also been adopted by the sports science industry. Various garments have been developed to improve the efficiency of muscles by stabilising muscles and improving circulation/ lactic acid removal. Today, compression stockings are available in a wide range of opacities, colors, styles and sizes, making them virtually indistinguishable from regular hosiery or socks.
