Properties of textile compression materials

Elastic compression stockings feature elasticity in both longitudinal and crossways directions because of knitwear s structure. Elasticity in cross-direction plays an important role in the application of the stockings when pulling them with the lowest diameter over a significantly bigger size of heel and instep. 

Therefore the results of these methods are only approximated values for defined areas of the leg. 

Over the years many direct in vivo methods have been developed, including the following. 

In recent years so-called evidence-based medicine has been used as a practical tool to assess the clinical efficacy of medicines and medical devices. With compression products, evidence-based compression therapy serves as a quality control procedure and helps to dehver the efficiency statements which service providers require for payment for the accordant therapy services. In practice, compression products should be subjected to appraisal by randomized and monitored studies which investigate the compression therapy process and produce proof of effectiveness. An important objective of this investigation is the resulting contact pressure following the application of the compression product. Attempts should be made to carry out direct in vivo determination of the compression pressure or the chronological pressure profile on patients.
