The Hip Knee Ankle Foot Orthosis is similar to a KAFO, but with the addition of hip joints and a waist belt. This is not often used as most individuals who require one of these devices prefer to use a wheelchair due to the increased effort in using this style of device. Children are most often the ones who utilize these as the physical and psychological benefits of weight bearing activities are well documented. However the RGO will often replace this device due to the option to walk with a Reciprocating Gait Orthosis.
