Контекст такой:
Unfortunately many of the commercially available supports are knitted in tubular form without proximal and distal flares. This not only leads to undesirable vasoconstriction but also inhibits muscle
tonus with further atrophy additionally affecting the stability.

Заранее спасибо!

The construction elements are identical in all supports as follows:
Especially fabricated borders with pressure reduction flares which will prevent
vasoconstriction.
