Physician describes Pistorius as a 'paradox'

Oscar Pistorius is a “paradox” whose past triumphs as a sprinter contrasted with the daily, severe limitations he endured because of his disability, a physician has told the athlete’s murder trial.

Wayne Derman, a professor of sport and exercise medicine at the University of Cape Town, said in court that the contrast likely contributed to stress and anxiety for Pistorius, who fatally shot girlfriend Reeva Steenkamp through a closed toilet door in his home.
