Low-Cost Prosthetic Knee Mimics Walking Motion

Researchers at the Massachusetts Institute of Technology designed a low-cost prosthetic knee that mimics normal walking motion. The MIT team's prototype generates a torque profile similar to that of able-bodied knees, using only simple mechanical elements like springs and dampers. The team is testing the prosthetic knee in India, an area with approximately 230,000 above-knee amputees.
