title: Compression bandages: influence of techniques of use on their clinical efficiency and tolerance.
abstract: OBJECTIVE
  A bandage is characterized by its components and by its properties evaluated in vitro: stretch theoretical pressures calculated with a dynamometer. A bandage is also characterized by properties evaluated in vivo: interface pressures at rest and during contraction. The aims of this study were to evaluate interface pressures and stiffness of medium stretch bandages and to vary the techniques of bandage in order to obtain a bandage with the lowest possible resting pressure and the highest possible working pressure.
  
  
  METHODS
  The interface pressures of Biflex 16 bandages of 7 mx8 cm and of Biflex 17 of 5 mx8 cm were measured with the Kikuhime device. Five techniques to make a bandage were used: two with an overlap of 50% and 75% respectively and a stretch of 30%, two with a superimposition of 2 bandages used in the same conditions as above, and one in spica (in turns of 8-technique).
  
  
  RESULTS
  The achieved pressures are related to the technique of making a bandage and the number of layers at the measurement points. The best result is obtained with the Biflex 16 with an use in spica without stretch: the resting pressure is low and the working pressure is high. The stiffness index and the low resting pressure are sufficient to give a good clinical efficacy.
  
  
  CONCLUSIONS
  This technique of use should be appropriate for the treatment of trophic disorders with a satisfactory effect of auto-massage and a maximum of safety even in a patient confined to bed or with a decreased ankle-brachial index (between 0.6 and 0.9).
