"HOPSA-dress"

The HOPSA-dress provides vertical orientation, without the need for weightbearing, to children with multiple disabilities. Items with interesting textures can be placed near the feet for tactile stimulation. Later, the pulley system can be adjusted so that the child can bear weight gradually, at their own pace.
