PRETORIA, South Africa - Oscar Pistorius is a "paradox" whose past triumphs as a sprinter crossing the finish line with raised arms contrasted sharply with the daily, severe limitations that he endured because of his disability, a physician testified Thursday at the runners 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. He testified for the defence, which wants to show that the athlete had a deep sense of vulnerability and it was a factor in what he has described as a mistaken shooting. "Youve got a paradox of an individual who is supremely able, and youve got an individual who is significantly disabled," said Derman, who has worked with South African Olympic and Paralympic teams and has treated Pistorius over half a dozen years. He noted that Pistorius anxieties included concern about flying. "He has a specific fear of being trapped somewhere without being able to move very rapidly," Derman said. Referring to Pistorius decision to confront a perceived threat on the night he killed Steenkamp, Derman said "fleeing was not an option" because the runner has no lower legs. Pistorius, 27, says he killed Steenkamp on Feb. 14, 2013 by mistake, thinking there was a dangerous intruder in his home. He shot her while on his stumps. The prosecution says he intentionally killed the 29-year-old model after the couple had a Valentines Day argument. Pistorius, who is free on bail, faces 25 years to life in prison if found guilty of premeditated murder, but he could also be sentenced to a shorter prison term if convicted of murder without premeditation or negligent killing. Additionally, he faces separate gun-related charges. During cross-examination, prosecutor Gerrie Nel said Derman, the physician, was giving "character evidence" rather than "expert evidence" and questioned whether the witness was capable of giving testimony that would work against Pistorius defence. "The truth would come before my patient," Derman said. Nel countered: "You cannot give evidence against your patient, sir."

DALLAS -- Rich Peverley doesnt know when he and his doctors will decide whether he can resume his career after he collapsed during a game because of an irregular heartbeat. The Dallas Stars arent going to press their 31-year-old forward for an answer, either. Peverley said Tuesday he would have to undergo testing that would include workouts to elevate his heart rate. "Im not sure where that will be," Peverley said before he and his teammates scattered for the summer after a first-round playoff loss to Anaheim. "That will have to be the first thing." Coach Lindy Ruff and general manager Jim Nill said all decisions would be up to Peverley and his doctors. Training camp is about five months away. "Thats a situation I look back on and thats totally in Richs hands -- Richs hands and the doctors hands," Ruff said. "Sometimes I look at it that its in Gods hands too." Peverley went down on the bench early in a game against Columbus on March 10 and had to be revived by medical personnel at the arena. He spent a couple of days in the hospital before going to Clevelland for a procedure to try to correct his heart condition, called atrial fibrillation.dddddddddddd The condition was diagnosed in training camp last year, and Peverley chose medication and a quicker return over undergoing the procedure and missing several months. He played most of the season with no issues before the condition flared up about a week before his collapse. Peverley, who wears a heart monitor on his waist at all times, found a way to contribute late in the season and in the playoffs by offering insights from the press box and giving teammates tips on faceoffs during off days. "Just being able to help out with the team somehow, it felt like I was accomplishing something," Peverley said. The Stars acquired Peverley and leading scorer Tyler Seguin from Boston in an off-season trade. Peverley has a year left on his contract. "Well wait for the doctors," Nill said. "Theyve got medical things they have to take care of. Once we kind of figure that out, I think well sit down with Rich and kind of decide the game plan moving forward from there." ' ' '
