Principle and effects of compression
The concept of compression therapy is based on the principle of applying an elastic garment around the leg.
By compressing the leg with 'graduated compression' (strongest at the ankle and decreasing going up the leg), the compression stocking acts as a layer of muscle by gently squeezing the stretched vein walls closer together, allowing the valves to close. The pooling of the blood is reduced, thereby restoring blood flow to a normal state and aiding overall circulation.
Compression socks and stockings help the blood return to the heart, shrink distended veins, prevent skin breakdown, and efficiently relieve aching and heavy legs.
Depending on the severity of the problem, medical compression therapy can be applied in different forms: socks, stockings (calf or thigh-length), or pantyhose
