David Teslow can no longer manage a round of golf without supplemental oxygen, but on Thursday the 82-year-old's cheeks were huffing and puffing as he played "On Top of Old Smokey" and "Wild Irish Rose" on the harmonica, along with bandmates in the lobby of Methodist Hospital in St. Louis Park.
"Old-time songs," he said.
Teslow is part of the harmonica group formed at Methodist last June as an adjunct therapy for patients with breathing disorders such as chronic obstructive pulmonary disease and asthma. While also completing traditional rehab exercises, the patients gain physical and psychological benefits from being part of the band, which practices every other week.
Rehab patients need to "exercise muscles that help push and pull air out of the lungs," said Dawn McDougal Miller, a music therapist at Methodist. "This gives them another way to do those exercises, and it's a whole lot more fun."
Playing the harmonica as an exercise makes intuitive sense. Most wind instruments such as the clarinet only produce notes on exhales, but the full range of notes on the harmonica requires both exhales and inhales. Research hasn't validated its effectiveness as an add-on to pulmonary rehab, though. The only published study found no benefit in 2012 when comparing a group of pulmonary rehab patients in Arizona who played harmonica vs. others who received standard therapy only.
The approach has nonetheless spread rapidly in the U.S., buoyed by a nonprofit Harmonicas for Health program that supplies hospitals with instruments and by positive reports emerging from renowned medical centers such as the Mayo Clinic.
Miller said the participants in the Arizona study were given one training session and sent home with practice exercises, whereas Methodist's program involves repeat instruction from a music therapist and group practices.
"We have people in this group who have never read music in their life," she said, "and then we have others who are very accomplished musicians. We even have a band director in that group, a bell-choir member, some pianists, but what's nice is you don't have to be able to read music to play the harmonica. It's an accessible instrument."
