Interface pressure of three different multilayer bandages systems in healthy volunteers: Results of a prospective clinical study

Objective: To compare variation in interface pressures of three compression systems: the four-layer bandage (4LB)*, the two-layer short-stretch bandage (SSB)** and the two-layer Dual Compression System (DCS)***. Interface pressures were recorded over seven days in healthy volunteers in different positions: supine, sitting, active standing and working pressure during exercise.

Method: Twenty-four healthy volunteers were bandaged with one of the three compression systems on both legs. Interface pressures were measured at inclusion (day 0) and on days 1, 3 and 7 using an air sensor system, with the sensor placed in the medial B1 position above the inner ankle. In addition, the volume of the lower legs was also measured on days 0 and 7 using a three-dimensional imaging system. Comfort and tolerability were also assessed.

l Results: The performance, based on the loss of interface pressure compared with baseline, of the DCS was partially better than that of the SSB for maximal working pressure and loss of volume. The DCS and SSB had similar results for the supine, sitting and active standing positions. No difference was observed between the DCS and the 4LB for the maximal working pressure. However, the DCS compared better than the two other systems for comfort and tolerability: 25% of the patients treated with the 4LB discontinued the treatment after three days because of pain.

lConclusion: The DCS maintained, over one week, a level of sub-bandage pressure similar to a 4LB and partially better than a SSB. However, the volunteers found the DCS more comfortable and tolerable than the other two systems.
