One of the biggest frustrations for above knee (AK) amputees is in the inability to extend the lower shin portion of their leg. This is termed the "extension phase." Very few, but some manufacturers of prosthetic limbs have included a feature to facilitate this energy-storing feature. SymbioTechsUSA has an innovative product in the form of an energy-storing knee that mimics both the quadriceps and hamstring muscles.
