How Activa Works
Compression therapy has been repeatedly proven effective in the treatment and prevention of venous disorders. Medical research has shown that stockings are effective in reducing leg symptoms only when the compression is graduated, meaning the pressure is greatest at the ankle and sequentially less up the leg.

The compression of the hosiery physically reduces the circumference of the limb and the superficial veins. By decreasing the size of the veins, blood flows faster, which helps prevent the blood from pooling and the chances of developing a thrombus.

Leg Compressions

Effects of 18 mm of compression on femoral vein blood flow velocity
of supine subject. Compression given in reduction of total limb volume
and vein diameter. The result is increased blood flow velocity.

Compression therapy can also improve valve functioning. As the vein diameter is reduced, the valve cusps are moved back to a correct overlapping position, allowing for proper functioning. Additionally, compression stockings can reinforce the varicosity, making it less symptomatic and less visible.
