Bionic ankles under the microscope: can they ease pressure on amputees?

This study looked at how powered ankle prostheses change the pressure inside the prosthetic socket and the health of the residual limb in people with below-knee amputations. Six adults who already use a standard prosthetic leg walked on level ground with different types of prostheses to compare socket pressures and skin blood flow. The goal is to help design better-fitting, more comfortable artificial limbs.
