ONLINE COVER Bionics replicate biomechanics. Lower-limb prostheses are often heavy, consume a lot of energy, and do not replicate the natural gait. Tran et al. have developed a powered prosthesis for above-knee amputees that possesses knee, ankle, and toe joints to replicate the biomechanics of the leg. The device is lightweight and capable of regenerating energy during walking to extend its battery life. The researchers validated their design with preclinical studies on above-knee amputees showing the ability to ambulate on level ground and on stairs. This month’s cover is a photograph of the prosthesis device: Utah Bionic Leg.
