## Abstract The relevance of the sensory system in the pathophysiology of cervical dystonia (CD) has been discussed since the description of sensory tricks associated with this disorder. Our objective was to locate changes in somatosensory processing of patients with CD responding in a passive sens

Abstract
Sensory gestes (SG) are a pathognomonic sign of dystonia, which can be detected in up to two thirds of patients with cervical dystonia (CD). They reduce dystonia severity markedly but transiently. We report a patient whose CD substantially worsened with sensory input to the back of the head and neck in different body postures, a phenomomen recently termed βreverseβ sensory geste (rSG) in craniocervical dystonia. In a cohort of CD outpatients, screening for βreverseβ effects of SG on dystonia yielded a prevalence of 12.8% (n = 6/47). The most frequent rSG pattern was increased dystonic activity in a supine, resting position while trying to fall asleep. The response to rSG persisted throughout the course of the disease arguing for an impairment of central integration of neck proprioception. Assessment of rSG should be included in the routine examination of CD patients, since BTX treatment may have to beadjusted accordingly to be efficacious. Β© 2008 Movement Disorder Society

Muscle activities in 26 patients with predominantly rotational torticollis were quantified using surface electromyography. In the subgroup of 19 patients with an effective sensory trick, different modes and bilateral locations of trick application led to significant (P < 0.002) reduction of electrom
## Abstract The geste antagoniste (GA), a relatively common feature of adultβonset primary dystonia, has been systematically evaluated only in cervical dystonia, but it is still unclear whether its frequency and phenomenology differ among the various forms of focal dystonia. We analysed the frequen
## Abstract Craniocervical muscles are the most frequently involved in dystonia, which can be either focal of segmental. While often experiencing an increase in dystonia with voluntary motor activity, many patients report temporary relief with __geste antagoniste__. We describe a patient who presen
## Abstract Geste antagonistes, or sensory tricks, are well described in focal dystonia affecting the neck, hand, and face. Improvement in dystonic movements is typically maintained while the trick is performed, but disappears when the geste ends. We investigated the phenomenological features of ge
