However, an international clinical trial led by teams at the University of Calgary, École Polytechnique Fédérale de Lausanne (EPFL) and University of Lausanne (UNIL) in Switzerland, and Sint Maartenskliniek, Radboudumc in the Netherlands has given him control again.

“Before the accident, I had no idea how volatile blood pressure can be. Just transferring from my bed to my chair almost knocked me out at times when my blood pressure would drop,” says Krebs. “At other times during the day, my blood pressure would spike due to severe nerve pain, causing me to break out in a sweat and experience severe migraines.”

Krebs is part of ongoing research at the University of Calgary based on a major discovery to stabilize blood pressure for people with SCI.
