PCD allows the higher-pressure values to be achieved in a shorter time, reducing the overall treatment time. These devices pump air into a bladder that inflates around the affected area thus applying pressure on to it. However, in order to preserve this effect, the static compression garment needs to be worn throughout the day.Īnother method of applying compression to improve blood flow is the use of Pneumatic Compression Devices (PCD). In order to see any significant improvement in circulation due to the compression provided by static socks, they need to be worn for a long period, which brings about significant discomfort. Hence, to reduce the swelling, the accumulated lymph needs to be moved out back into a region where the lymphatic system is working normally (John Hopkins Medical)Ĭompressions socks apply statically graded pressure distribution in the lower limbs, with the highest pressure being applied to the distal regions. ![]() In the case of lymphedema, swelling is a result of the accumulation of lymph due to the local or regional failure of the lymphatic system. This increase in circulation would significantly bring down swelling and reduce the pain felt by the patient. This pressure gradient also ensures there is no back flow of blood that would have been present due to the valves within the veins not closing tightly. the legs) are compressed, the increased pressure forces the blood to return to the heart. Compression therapy has been widely used as a treatment modality to alleviate symptoms associated with swelling of limbs.
