  • Participants with transfemoral amputation will be evaluated using both their current prosthetic knee and the Bio Leg.
  • The study measures functional mobility, movement efficiency, endurance and fatigue, and patient-reported experience.
  • Testing takes place at Brooks Rehabilitation, including the Brooks Motion Analysis Center, under clinical and rehabilitation specialists.

BionicM develops Bio Leg, a powered microprocessor knee for transfemoral amputees. The University of Tokyo spin-out combines motorized assistance, onboard sensing and movement control to support standing, walking and stair use. U.S. sales began in 2024, and the company completed its first customer deliveries that August.
