Fourteen months after he was knocked off his motor scooter near his Woolooware home leaving him with life-changing brain injuries, Glenn Wheeler returned for the first time to his old Channel Seven television stomping grounds on Thursday.

Wheeler returned to the Martin Place studio's for a special appearance to mark his 56th birthday, and while his speech was a little slower than how viewers remembered him, the sparkle was definitely still in his eye as he cracked jokes with The Morning Show host Larry Emdur.

Deborah Anne Levy, 60, was high on cannabis when she ploughed into Wheeler in her Mitsubishi Starwagon in Woolooware in February last year.

Wheeler suffered serious head injuries, had to be placed in an induced coma and spent nearly a year in hospital.

He told Emdur: "I am doing some things reasonably well, like eating and drinking ... but there are other things I can not do anymore because of my injury."

The former Seven Network and 2GB presenter has also spent several months recuperating in the Liverpool Brain Injury Rehabilitation Unit.

In March, Levy was sentenced in Sutherland Local Court to a seven-month suspended sentence on a charge of negligent driving occasioning grievous bodily harm.

Magistrate Julie Huber also ordered Levy to undergo psychiatric counselling and drug or alcohol rehabilitation in line with Community Corrections Service directions.

A second charge of driving under the influence was dealt with by way of a two-year good behaviour bond.

Levy was also handed a three-year and a one-year driving ban for the two separate charges.

Following the judgement Wheeler's son, Dane,  said the accident had turned his father's life upside down.

"She's turned what used to be a fabulous, bright, happy, successful, amazing man's life upside down in one hit and it sucks," he told reporters.
