Variable-mechanical-impedance artificial legs

摘要: In one aspect, the invention provides methods and apparatus facilitating an adjustable-stiffness prosthesis or orthosis (including approximations to arbitrarily definable non-linear spring functions). Spring rates may be varied under no-load conditions during a walking gate cycle minimize power consumption. another for outputting positive from orthosis, high-performance artificial limbs. embodiment of invention, is transferred functioning muscle which mimics assists non-functioning impaired muscle. comes on-board source in orthosis.
