If you have or know someone with a limb difference:

The Problem:
Because all currently available lower-limb prosthetics are either unpowered or underpowered, excess strain is placed on an amputee's existing joints and muscles.
For transfemoral (above-knee) amputees, the muscles and joints in the hip, back, and sound limb are tasked with providing all of the energy that would typically be provided by the amputated limb. This transfer of loads causes:
-
Fatigue
Energy consumption when walking is increased by up to 80% for unilateral above-knee amputees and up to 300% for bilateral above-knee amputees.
-
Pain
For more than 50% of patients, increased loads on hip joint and postural changes from hindered gaits lead to back pain. Amputees often consider this pain worse than residual limb pain and phantom pain.
-
Lack of Mobility
Ascending and descending stairs and inclines, standing, etc. require unnatural movements to compensate for a lack of a powered knee joint. These complex motions are also generally much more challenging for amputees.
