"I was left-handed," she said. "So I'm learning to do everything right-handed, which is hard."

One place Withers has sought help is Colorado State University. The university puts on a therapy class unlike almost any other.

The class is all music all the time - but not just for the fun of it.

Research started at CSU two decades ago has shown a direct, physiological link between music and movement.

"The motor system responds very strongly to patterns of sound and rhythm," CSU's Dr. Michael Thaut, one of original researchers, said.

Just like a pianist uses rhythm to learn complex finger patterns, a stroke victim can use rhythm to relearn how to walk, according to Thaut.

"The idea is we use music as a big clock function from the outside that gives a steady pulse and steady pattern that synchronizes the movement," Thaut said.

Therapists across the world treating those with brain injuries and illnesses have found success with this technique, much to the delight of Thaut.

"It's a local source that has gone world-wide," he said.

Poudre Valley Hospital also contributed to this research over the years.

Thaut says one of the largest goals in this field is to teach more and more therapists about the connection between music and movement.

As for Withers, she's walking again.

"When I'm walking by myself now I usually have a tune going in my head," she said.
