C-Leg technology offers the advantages of permanent stance phase control, the ability to weight the prosthesis during flexion, dynamic alignment, less energy expenditure while walking, and relief for the sound side and the rest of the body. Thats partially due to personal preference, but also because theres a wide range of abilities among people who are blind. Bats specialized auditory and nervous systems have evolved to overcome this problem, but for humans, echolocation doesnt come naturally. A successful biomimetic device for the blind, then, would have to accommodate a wide variety of preferences.
