Correct desk height also assists fine motor skills. Many children who use a wheelchair can and should sit in a normal classroom chair at preschool and school. This makes them more a part of the group. If it is more appropriate to sit in the wheelchair, a special desk may be needed so the wheelchair fits under easily. How well and how much a child walks, depends on many factors besides how much movement he or she has.
Motivation is a big factor.
Some children love to walk, and walk well with the appropriate gear. For others, it is a real chore. This must be agreed between parents and the school with advice from a physiotherapist where appropriate. It must be practical and fit in with both the school's needs and the child's educational needs. Obviously, it is good to achieve regular walking at school if that is possible.
