Various patterns of gestes antagonistes in cervical dystonia.

In this study, we evaluated patterns, quantity and effectiveness of gestes antagonistes, the association between the severity of disease and the type of gestes and the clinical implications of the presence of gestes antagonistes in 33 patients with cervical dystonia, 19 patients (58%) presented a classic sensory trick (ST) while 14 subjects (42%) demonstrated a forcible trick (FT). FTs prevailed in patients with more severe dystonia whereas STs were more common among patients with milder disease. These results suggest that at more severe stages of the disease, classic STs are not effective enough and thus patients use FTs.
