Ms Hand, a mother-of-one, told the court how McGregor had pinned her to a bed before assaulting her.
She was left with extensive bruises and abrasions over her body, including on her hands and wrists.
There was a bloodied scratch on her breast and tenderness on her neck after she said she was placed in a “chokehold” by McGregor.
He denied causing the bruising, saying it could have happened after she “swan dived” into the bath in the hotel room.
Ms Hand was taken in an ambulance to the Rotunda Hospital in Dublin the next day where she was assessed in the sexual assault treatment unit.
A paramedic who examined Ms Hand told the court that she had not seen “someone so bruised” in a long time.
The jury had been told how Ms Hand had to leave her job as a hairdresser and has not been able to work since due to her mental health, that her relationship with her partner ended months after the incident, that she had to move out of her home in Drimnagh and that her mortgage was now in arrears.
She also said she had to stop seeing a counsellor because she could no longer afford to pay for the sessions.
The court heard that she had spent more than €4,000 (£3,326) on GP, pharmacy and psychotherapy costs.
