Compared to a walker, a gait trainer offers more extensive support and is typically used by children who are not able to consistently bear full weight through the legs. These children need additional support to stand and take steps independently. Relevant diagnosis can be for example cerebral palsy, Rett syndrome, traumatic brain injury, and the children are non-ambulatory.

Wherease children who are expected to use a typical walker in the future may be in need of a gait trainer as a training device over a period of time to develop independent walking ability with minimal support. This may be children with motor function levels corresponding to cerebral palsy, GMFCS II and III.

For a child with a disability taking his or hers  first steps supported by an assistive device is an important moment and milestone, for both the child and the parents.  Mobility in standing allows the child to experience its environment from a whole new perspective and let the child become more independent. It also stimulates to more activity and participation with peers. 

Furthermore, upright mobility is also beneficial for general health and well-being. It has positive impact on joints, muscles, bones, respiration, bowl and bladder function as well as psychological and cognitive development.
