Mrs Miller�s husband Tony said he rushed to his wife�s side after hearing about the accident from a witness.
He had arranged to meet her in a nearby coffee shop and had been waiting for her to arrive.
Mr Miller said the accident took place about 9.30am on Wednesday, May 6.
He is appealing for witnesses to contact him on 9247 3950 or 0417 991 418.
�I found my wife sprawled on the footpath and a paramedic, who happened to be passing by at the time, was attending to her,� he said.
�My wife was extremely distressed, my focus was on her, but I remember a few other people being near her.� Mrs Miller is recovering at home after spending two days in Royal Perth Hospital.
Her damaged scooter is no longer roadworthy.
Project manager for Jolimont-based builders Cooper and Oxley Allan Penaranda said the incident was under investigation. He said the Shire of Kalamunda endorsed closure of the footpath near where the accident happened.
In future, signs will direct pedestrians to cross Barber Street via ramps to the footpath on the opposite side of the road.
