Leg exoskeleton reduces the metabolic cost of human hopping.
During bouncing gaits such as hopping and running, leg muscles generate force to enable elastic energy storage and return primarily from tendons and, thus, demand metabolic energy. In an effort to reduce metabolic demand, we designed two elastic leg exoskeletons that act in parallel with the wearer's legs; one exoskeleton consisted of a multiple leaf (MLE) and the other of a single leaf (SLE) s...
متن کاملA spring in your step: some is good, more is not always better.
WHEN HUMANS AND OTHER ANIMALS run and hop, they operate with muscle efficiencies nearly twice those observed during cycling (2, 4). This “free energy” is due to the storage and return of elastic energy in muscles and tendons during the stretch-shorten cycles of landing and takeoff (1). If spring-like tendons and muscles can save substantial energy, could artificial springs added to the legs fur...
متن کاملBionic ankle-foot prosthesis normalizes walking gait for persons with leg amputation.
Over time, leg prostheses have improved in design, but have been incapable of actively adapting to different walking velocities in a manner comparable to a biological limb. People with a leg amputation using such commercially available passive-elastic prostheses require significantly more metabolic energy to walk at the same velocities, prefer to walk slower and have abnormal biomechanics compa...
