Darlene Denzer danced through life.
She could do-si-do, fan kick and plié. After she got married, she and her husband two-stepped and polkaed.
"My husband sure liked to kick his heels up," she said with a laugh.
During a routine doctor's visit six years ago, however, Denzer was diagnosed with Parkinson's disorder. The Cottage Grove woman didn't let that stop her. She dragged her husband to ballroom lessons for a year until they finally called it quits.
Then, one day during a physical therapy session, Denzer happened to see a pamphlet about a dance class for people with limited mobility.
Now every Thursday, she joins as many as a dozen other dancers at the Jewish Community Center in St. Paul. Even though her slowly progressing disease makes movement more difficult, she takes part in the seated warm-ups, stretches and short dance sequences.
While it's one of only two such classes in the state, programs like it are spreading across the country.
"Dance is one of those things that just makes the patient be able to flow with their movement when they can't otherwise move," said Dr. Lynn Struck, a neurologist at UnityPoint Health-Des Moines. "There's no explanation of why it happens, we just know it works."
