On a sweltering summer's day ... a group of people with Parkinson's Disease began rock-climbing on the Carderock Cliffs of Maryland. It's all part of their therapy, says Molly Cupka, the no-nonsense instructor and cheerleader for this community. She started this program, called UpENDing Parkinsons, as a non-profit twelve years ago. There's a lot of balance involved, mobility involved, strength, cardio, and then there's the cognitive part, where you have to look at the hold, and figure out how to get your body to move to get to that hold," she said. There's no cure for Parkinson's, which usually affects mobility, coordination, balance, and even speech. Some people with Parkinson's, like Vivek Puri, get dyskinesia (involuntary jerking motions). Puri ... was only 38 when he found out he had Parkinson's. "Fine motor skills have kind of really suffered dramatically," he said. "When I don't climb for some periods of time, I get worse." But once he gets on the wall, he calls himself Spider-Man. "Honestly, I climb like a monkey," he said. "I get my finger strength moving, which gets my fine motor skills " maybe not back, but kind of keeps that in motion." Cupka joined forces with Marymount University last year to study patients climbing for the first time. "We have people literally walking and carrying weights, you know, walking and looking, multitasking," she said. The study found that, in so many words, if you climb, you may walk better.
