Advances on mechanical designs for assistive ankle-foot orthoses

Desk Chair Assistive ankle-foot orthoses (AAFOs) are powerful solutions to assist or rehabilitate gait on humans.Existing AAFO technologies include passive, quasi-passive, and active principles to provide assistance to the users, and their mechanical configuration and control depend on the eventual support they aim for within the gait pattern.In th
