A disabled woman who was the victim of a terrifying home invasion by three masked and armed men now barricades herself in her new home and keeps a knife under her pillow.

"I'm an emotional, nervous, mental wreck," she said in her victim impact statement read out at the sentence hearing of Domenic Ietto in the South Australian District Court on Tuesday.

Ietto, 27, has pleaded guilty to aggravated charges of serious criminal trespass in a place of residence and attempted robbery on April 16, 2013, at Kudla, on Adelaide's northern outskirts.

Decorated former soldier Michael Quintrell, 32, was jailed for seven years and eight months last year for the same offences, but the third invader has never been caught.

The trio stormed the house of a drug dealer who was growing cannabis plants hydroponically in the shed and who stabbed Quintrell and Ietto during the confrontation.

The disabled woman, who has a muscle disease exacerbated by stress and pain, and her adult son also lived at the premises.

In her victim impact statement, she said she was watching the Simpsons on TV before she was knelt on, hit in the head with a pistol and put in a headlock.

"I wished they had pulled the trigger and killed me," she said.

She had chronic nightmares if she managed to sleep and was in fear of the third man who had not been caught.

"He may hunt me down and kill me because I rang the police and the two others got caught."

He had seen her but she did not know what he looked like, she added.

Ietto will be sentenced on April 1.
