"Comparing sub-bandage pressure and stiffness dynamics in two two-component compression systems for the lower limb:...

BackgroundTwo-component cohesive compression systems are available for compression therapy.ObjectivesTo assess the sub-bandage pressure and stiffness of the two-component compression systems, Coban and CoFlex, and to investigate how an additional partial compression layer after two hours and the experience of the therapist impact these outcomes.MethodsThe study examined 19 patients whose lower limbs were bandaged by either a trainee or an experienced physical therapist. Sub-bandage pressures were measured using PicoPress® sensors placed 10 cm and 25 cm proximal to the medial malleolus. Additionally, the Static Stiffness Index (SSI) and Dynamic Stiffness Index (DSI) were calculated.ResultsThe addition of a partial compression layer on the ventral side of the leg significantly increased sub-bandage pressure and DSI. SSI effects were significant at 10 cm, but not at 25 cm height. Coban generated significantly higher pressures than CoFlex, while the level of experience of the therapist showed no significant influence.ConclusionsThe addition of a partial compression layer effectively increases sub-bandage pressure, with Coban exerting higher pressure than CoFlex. However, the level of experience of the therapist does not significantly influence the compression outcomes.
