Compared to passive devices, powered prosthetic legs may enable individuals with lower limb amputation to walk more smoothly using less energy, ambulate more efficiently up stairs and ramps, and perform sit-to-stand transitions more easily. However, such devices are heavy, and control systems for these devices require manual transitions between activities.
With previous grant funding, we have developed a novel, lightweight hybrid prosthetic leg that can function as a powered or passive device and is controlled by an adaptive pattern recognition control system that enables safe, automatic, and seamless transitions between ambulation modes.
For this project, we will compare biomechanics and community activity of subjects using their commercially available, passive devices and our novel, lightweight hybrid prosthetic leg. More clinical trial details can be found here.
