HiFi Benefits

  • Biochemical Design Locks Bone into Place Making Limb Rotation Very Difficult
  • Significantly Lower Trim Lines
  • Better Control While Using Less Energy
  • Greater Range of Motion
  • Reduced Heat
  • More Comfortable Overall
  • Makes Prosthesis Feel Like It’s a Part of Your Body
  • Less Bone Movement within Interface Itself

HiFi Difference

Having an inner flexible interface surrounded by a frame with struts and windows is a common approach that has been used for a long time. A traditional frame style socket is designed to save a small amount of weight while theoretically allowing some room for contracting muscles to bulge against the flexible material not backed by the rigid frame. It applies a global compression to the entire limb. This is not the same as applying the biomechanical principles of alternating compression and release, a hallmark of the High-Fidelity design. In the High-Fidelity Interface the level of compression imparted by the struts displaces a significant amount of your limb’s soft tissue out through the windows or release areas depending on the style of High-Fidelity Interface chosen. The reduced volume of tissue “left behind” allows the compression struts to get closer to the underlying bone because there is simply less soft tissue in the way. By being closer to the underlying bone, there is less ability for the bone to move within the interface itself, a common problem with traditional sockets. http://www.biodesigns.com/hifi.html

Who is a candidate for HiFi?

Upper and lower limb wearers have had great success fitting into HiFi, especially those amputees in need of greater stability and comfort.  Although most amputees can benefits from the HiFi design, it is extremely effective for those who are very active and demanding on their prosthesis.
