The name boogie-woogie is used mostly in Europe; the closest thing in the US is probably East Coast Swing. What today is called boogie-woogie would during the 1950s have been called rock'n'roll. The term boogie woogie is confusing; the dance can be danced to the music style called boogie-woogie but is most often danced to rock music of various kinds. The name was taken since the name rock'n'roll used in competition dance was already taken by a highly acrobatic dance form. Boogie woogie as a competition dance is a led dance, not choreographed, and contains no acrobatic elements.
