A new modification of KAFO for assistance in knee extension

Abstract

In this paper, a dynamic knee – ankle – foot orthosis (KAFO) extension assisted with elastic support, has been described which contributes to stance phase stability and swing phase freedom. The temporal distance factors including velocity, cadence, stride length, and clinical gait assessment score (CGAS) with bare foot and orthosis have been documented. The orthosis enables walking without fully immobilizing the knee.
