The countdown and final checklist review happen every morning for Stephen Scott (in photo). He gets up in the early morning hours to make his coffee. He turns on the TV. He channels his inner-astronaut and puts on his space pants one leg at a time. He attaches the portable water pump to the space pants. He flips a switch and then settles into his recliner for 90 minutes of therapy. The space pants and pump are two items being used in a clinical trial led by a Purdue researcher who is exploring the use of non-surgical and in-home options to help people such as Scott manage peripheral artery disease (PAD).
