Take a Step in the Right Direction


Easy for practitioners to calibrate, even easier for patients to use, the integrated, low-profile joint of the E-MAG Active KAFO provides the best in electronic stance control to help your patient live a more active lifestyle. The stance control function will remain locked during weight bearing, then unlocks for swing phase. It simplifies gait training and allows for varied cadence to help meet your patient’s specific needs.Calibrating the E-MAG Active is simple, and it is just as simple to recaliabrate if your patient's needs should change over time.

With no linkage or sensors below the knee, the E-MAG Active is the perfect solution for those patients who have limited ankle function or who would normally wear a locked KAFO—and it even accommodates a joint contracture of up to 15°.
