CEDAR RAPIDS — Rebecca Strabala spent years of her life honing her dance ability — and now she’s bringing that experience to Mercy’s rehabilitation team.Strabala has spearheaded an effort to introduce dance-specific physical therapy in Cedar Rapids since she joined Mercy Medical Center staff in February 2017, a service she wished she had when recovering from a dance injury herself.“I was injured when I was in college and I went to a physical therapist for that,” she said.
