Rande Davis Gedaliah's 2003 diagnosis of Parkinson's was followed by leg spasms, balance problems, difficulty walking, and ultimately a serious fall in the shower. But something remarkable happened when the 60-year-old public speaking coach turned to an oldies station on her shower radio: She could move her leg with ease, her balance improved, and, she couldn't stop dancing. Now, she puts on her iPod and pumps in Springsteen's "Born in the U.S.A." when she wants to walk quickly; for a slower pace, Queen's "We Are the Champions" does the trick.
