The Dutch Parkinson's Society has released its own controversial take on the Harlem Shake dance craze featuring a sufferer of Parkinson's disease.
In the clip, society chairman Eric Roos shakes out of control in an office kitchen because of a lack of medication while the song Harlem Shake by Baauer plays.
The video imitates the Harlem Shake internet meme, in which one person dances to the song apparently unnoticed by those around them for 15 seconds before the bass drops and everyone joins in.
But instead of others dancing with Mr Roos, the video ends with him falling to the floor and colleagues running to his aid.
The clip, created by advertising agency Saatchi & Saatchi, ends with slogan, "Shaking, fun for some … daily struggle for others".
On its website, the group said the footage aimed to shock viewers and show the daily reality of the disease was much more than a trembling hand or foot.
However, some viewers questioned the tastefulness of the society's video.
The Harlem Shake is a viral trend created by a group of teenage boys on the Sunshine Coast.
