To examine the effectiveness of a previously developed pair of pumps to reduce leg swelling, a crossover, single-blind study was conducted, in which the developed and general pumps were alternately worn, with measures to prevent the distinction between them. Leg swelling was assessed by calculating the lower limb volume using the water displacement method. The subjects were 24 legs of 12 female university students. Comparison of lower limb volumes in the morning and evening revealed a decrease of 15.4 ±19.5 mL with the developed pumps, and an increase of 41.7±14.0 mL with the general pumps, showing a significant difference (p<0.05). The decrease in the lower limb volume with the developed pumps confirmed their effectiveness in reducing leg swelling.
