Mode of Operation

The CDS® Knee Brace Extension functions according to the CDS®-principle and has been designed to treat an extension deficit of the knee. The brace applies a dynamic low load prolonged stretch to stimulate growth in the contracted tissue. The adjustable redression range protects the tissue from painful overstretching and allows for individual extension until -15°.
