Comparison between SACH foot and a new multiaxial prosthetic foot during walking in hypomobile transtibial amputees: physiological responses and functional assessment.

Background: The most prescribed prosthetic foot for hypomobile transtibial amputees (TTAs) is the solid ankle cushion heel (SACH). Recently, the new 1M10 Adjust (Ottobock, Duderstadt, Germany) has been designed for hypomobile TTAs. No studies are available about the physiological responses to walking with 1M10 Adjust or about the related energy cost of walking (ECW).
