Many patients have multiple sensory tricks and sometimes merely the thought of executing the trick may reduce the dystonia. In one study, 54% of patients demonstrated more than one geste antagoniste, and clinically significant reduction of head deviation occurred in 82%.(4) 

The paper by Broussolle, et al features many vintage photographs from papers written around the turn of the 20th century.(5) Authors from that era argued that a geste antagoniste proved cervical dystonia was psychogenic. It seemed too bizarre to be real. Decades passed before others pointed out the error of this thinking. In a complete reversal, the presence of a geste antagoniste is now seen as evidence for rather than against organicity.

Video legend. The geste antagoniste (sensory trick, counterpressure sign, proprioceptive trick) is a maneuver done by patients to control dystonic movements and postures. For instance, patients with cervical dystonia may learn they can straighten their head by placing a hand or finger somewhere on the face, chin or back of the head or performing some other maneuver to provide sensory stimulation or light counterpressure.
