Abstract Background: ReadyWrap(R) Calf, Rosidal(R) Sys and Urgo K2(R) respond to the same physical laws. But they were studied with different methods. This makes it difficult to compare them. ReadyWrap(R) Calf has an estimated stretch of 60 %. After 5 hours of wear in healthy volunteers, its static stiffness index (SSI) is around 15 mmHg when applied with a resting pressure of 40 mmHg. The SSI of Rosidal(R) Sys and Urgo K2(R) remains constant before and after a 30-minute treadmill test (25 mmHg for Rosidal(R) Sys and 15 mmHg for Urgo K2(R)). The aim of this trial is to study these compression devices using the same method, with a view to carrying out comparative clinical trials at a later date. Aim of the study: The purpose of this pilot study was to compare the interface pressures and stiffness indices of three compression devices (ReadyWrap(R) Calf, Urgo K2(R) and Rosidal(R) Sys) on volunteer subjects before and after a 15 min treadmill test. Materials and methods: We selected 40 volunteer subjects treated with ReadyWrap(R) Calf after randomization on one leg and on the other leg with 20 with Rosidal(R) Sys or 20 with Urgo K2(R). We measured interface pressures in standing, lying position and during ankle dorsiflexion. We calculated the SSI and Dynamic Stiffness Index (DSI) before and after a 15 min treadmill test. We also carried out a VAS on comfort. Results: Interface pressures decreased after the treadmill test with all three compression devices. ReadyWrap(R) Calf and Urgo K2(R) pressures, SSI and DSI before and after the treadmill test were not statistically different. Their Static Stiffness Indices are in the order of 13-14 mmHg. Only Rosidal(R) Sys has a significantly higher SSI. Comfort is found very comfortable under the 3 compression devices. Conclusion: The adjustable compression wrap, Readywrap(R) Calf, behaves like a stiff bandage when applied with a pressure of around 40 mmHg. Its different pressures and stiffnesses are comparable to the bandage kit Urgo K2(R).
