ActivePren™ is an active three-layer material consisting of two elastic jersey cover fabrics and a core made of neoprene foam. This material is characterized by softness and high flexibility. A very important advantage of this material is the fact that it is not a knitted product, it does not have thick fibers, so that the weaves of the material do not imprint on the patient's skin and do not cause abrasionsin places of high compression. Products made of ActivePren are the strongest and most effective stabilizing orthoses available on the market.


Splint 1R

1R splints – single axis orthopedic splints used in all knee joint and upper limb braces, where apart from adjustment of the flection and extension angle, high lateral stabilization of the joint is not required, but important if low weight of the brace. Due to the low weight the splints are successfully used in all braced for children. They are manufactured with high quality polyamide with carbon fibres, making the splints light and neutral to the influence of sweat and salt, properly firm therefore assuring correct functioning of the device. Adjustment of the flexion and extension angle is performed with special Allen screw in every 15°. Each brace is equipped with an Allen key, which is necessary for adjustment. Standard length of the braces is: 280 and 380 mm. The splint and its design are patented in European Union by Reh4Mat Company.

Patella stabilizers

Relief stabilizers of various shapes made in 2D technology. They are made of relieving foams connected on one side with a fabric friendly to the patient's skin, and on the other with a gripper, thanks to which the stabilizer can be attached to the adhesive element of the orthosis. Thanks to such a structure, these pads do not have to be sewn into the orthosis, and they can simply be fastened to it from the inside. These elements have an anatomical shape and are made of comfortable foam with proper hardness and elasticity, which guarantees the proper therapeutic effect.
