Clinical Studies
Inelastic compression legging produces gradient compression and significantly higher skin surface pressures compared with an elastic compression stocking.
Kline CN, Macias BR, Kraus E, Neuschwander TB, Angle N, Bergan J, Hargens AR.
Summary: This study compared skin surface pressures underneath the inelastic CircAid® garment with Built-In Pressure System set to 40mmHg vs. an elastic 30-40mmHg below-knee compression stocking. The CircAid® leggings produced significantly higher skin pressures than elastic leggings at both leg regions (p<.001). Mean pressures over all trials using the CircAid® leggings were 47±3 and 35±2 mmHg for ankle and below-knee regions, respectively. Mean pressures using the elastic leggings over all trials were 26±2 and 23±1mmHg for ankle and below-knee regions, respectively. Only the CircAid® leggings produced a significant reverse-pressure gradient between the knee and the ankle (p<.05), whereas the elastic leggings did not.

Comparison of elastic versus nonelastic compression in bilateral venous ulcers: a randomized trial.
Blecken SR, Villavicencio JL, Kao TC.
Summary: Conducted by J. Leonel Villavicencio MD, Director Vascular and Lymphatic Surgery Clinic. The completed study comparing 24 extremities shows that at three months, patients wearing the non-elastic CircAid system had significantly faster ulcer-healing rates as compared to patients wearing a conventional four layer elastic compression system.

Comparison of Costs and Healing Rates of Two Forms of Compression in Treating Venous Ulcers.
RG DePalma, M.D., RK Spence, M.D., JA Caprini, M.D., MR Nehler, M.D., J. Jenson, D.P.M., MP Goldman, M.D.,
Summary: WP Bundens, M.D. In a multi-center prospective, randomized study, the cost and healing rates for treatment of venous ulcers was compared between the CircAid T-3 Boot and Unna boot. Cost of treatment was significantly less. The total cost of treatment was 38% less with the T-3 Boot and this difference was statistically significant. Healing rates were 45% faster with T-3 Boots, though this value did not reach statistical significance because of large standard deviations.
