Studies on a Prone-board Conbination Wheelchair

Abstract

We have many patients with C. P and spinal cord injury who can not walk alone and using wheelchairs.
Wheelchairs are apt to make contractures of hip and knee joints.
The other way, hand propelled tilting prone boards are not only valuable for daily living but also privent deformities as well as correct contractures.
Now, we developed a new prone board conbination wheelchair, which is easily changeable each other quickly and securely.
When we change the unit from wheelchair to a prone board, lift the lever behind the chair, then the backrest falls down and the leg-rest arises simultaneusly.
After fully recline the back, ajust the caster alignment.
