Nei, harlem shake er hele kroppen, starter med shoulder movements å bygger seg nedover mot bena.

Edit: The Harlem shake, originally called the albee in Harlem, is a dance that started in 1981. The dance became mainstream in 2001 when G. Dep featured the Harlem shake in his music video Let's Get It. It has its history from an North-East African or Ethiopian (Abyssinian) dance called "Eskista" and was allegedly started in Harlem by a man named Al B. Its ancient form "Eskista" is still used in Ethiopia today.[1].
