Oscillatory head movements in cervical dystonia: Dystonia, tremor, or both?
Cervical dystonia is characterized by abnormal posturing of the head, often combined with tremor-like oscillatory head movements. The nature and source of these oscillatory head movements is controversial, so they were quantified to delineate their characteristics and develop a hypothetical model for their genesis. A magnetic search coil system was used to measure head movements in 14 subjects ...
متن کاملGender differences in head-neck segment dynamic stabilization during head acceleration.
PURPOSE Recent epidemiological research has revealed that gender differences exist in concussion incidence but no study has investigated why females may be at greater risk of concussion. Our purpose was to determine whether gender differences existed in head-neck segment kinematic and neuromuscular control variables responses to an external force application with and without neck muscle preacti...
متن کاملNeck proprioception and spatial orientation in cervical dystonia.
Neck muscle vibration is known to influence body orientation and posture during locomotion and stance in normal subjects. To verify the hypothesis that neck proprioceptive input can be misinterpreted in patients with cervical dystonia (CD), lateral continuous vibration was applied to the sternocleidomastoid muscle during both stepping-in-place and quiet stance, with eyes closed. The orienting r...
متن کاملThe influence of occlusal stabilization appliances on cervical dystonia symptoms
Objectives The aim of this study was to assess the therapeutic efficiency of the occlusal stabilization appliance (OSA) in patients with cervical dystonia (CD). Methods The study included 11 patients aged between 29 and 80 years, 7 women and 4 men, diagnosed with primary CD. The patients underwent an extra- and intra-oral clinical examination, followed by para-clinical examinations, necessary...
متن کاملDisturbances of dynamic balance in phasic cervical dystonia.
OBJECTIVE To quantitatively assess control of balance under static and dynamic conditions in patients with tonic and phasic cervical dystonia. METHODS Ten patients with purely tonic cervical dystonia with fixed postural deviation and 20 patients with cervical dystonia with phasic head movements were investigated at least 3 months after botulinum toxin injections. Seventeen age matched volunte...
