Using a Segway with hemiplegia

[amwebby]

My wife has severe hemiplegia as a result of a stroke suffered during a brain operation. She has some movement and use of her left leg but little-to-no use of her left hand or arm.

Has anyone any experience of this type of disability using a Segway? She uses a rotunda to stand so my thinking is she MAY be able to use a Segway as it is essentially a mobile rotunda. It would certainly take up less space than a wheelchair and may help to give her some measure of independence.
