Posterior dynamic element (PDE) is an advanced below-knee composite orthosis utilizing the PDE modular composite spring system for a range of orthotic applications including ankle and calf weakness. The orthosis facilitates postfitting adjustment and tuning to improve fluency and stability during gait and higher-level activities. Users may change the strut stiffness or ankle alignment for different activities; they can also adjust the device relative to the heel height of their shoe. Nine spring options are available for patients of various weights and activity levels.
One of the issues we have seen with the PDE is that the orthotist will often choose too weak of a strut and the patient will start to develop pain from having too much ankle Range of Motion during dynamic activities. This is why it is key to have a Physical Therapist and Orthotist work together to ensure the right fit is found.
