Karen Matthews said the wheelchair went missing from outside her front door on Buffet Ramble overnight between May 11 and 12.
Ms Matthews said it had an apple-green frame, hospital identification and her name on it, so initially she had hoped it would be returned.
�It�s very noticeable, with a black cushion and seat,� she said.
�It�s a specialised wheelchair.�
Ms Matthews said had been given the wheelchair about five years ago and had been struggling to get about using her walking frame since it went missing.
�I�m not very strong and my legs don�t function properly,� she said.
�I�m able to walk in the house, but when I leave the house I need the wheelchair for support.�
