Below-knee level amputation significantly impacts the ability of an individual to ambulate. Transtibial amputees are typically prescribed energetically passive ankle-foot prostheses that behave as a spring or controlled damper, and therefore cannot fully replace the function of the missing limb. More recently, fully-powered devices have been proposed to more closely match the power generation ability...
This paper is proposed to design a lower limb exoskeleton system for the people who can still generate electromyogram signal. While ascending and descending, the motion can be divided into stance phase and swing phase. According to foot pressure and electromyogram of rectus femoris and tibialis anterior, we establish an algorithm to estimate motion intention while ascending and descending. The exoskeleton...
