Neck 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 کاملAlleviating manoeuvres (sensory tricks) in cervical dystonia.
BACKGROUND There is limited information on the phenomenology, clinical characteristics and pathophysiology of alleviating manoeuvres (AM), also called 'sensory tricks' in cervical dystonia (CD). METHODS Individual data, collected from 10 sites participating in the Dystonia Coalition (http://clinicaltrials.gov/show/NCT01373424), included description of localisation and phenomenology of AM coll...
متن کاملChanges in cortical and pallidal oscillatory activity during the execution of a sensory trick in patients with cervical dystonia.
We examined the effects of a sensory trick (SeT) on cortical EEG and globus pallidus (GP) local field potentials in four cervical dystonia patients, two of whom had an effective SeT and two who did not. The application of an effective SeT was associated with bilateral desynchronization in the 6-8 Hz and beta bands in the GP and sensorimotor cortical regions. In contrast, mimicking an SeT led to...
متن کاملMultichannel Electromyographic Mapping to Optimize OnabotulinumtoxinA Efficacy in Cervical Dystonia
BACKGROUND Cervical dystonia (CD) is characterized by sustained, involuntary contraction of head and neck muscles. Botulinum toxin injections are established as safe and effective, but unfortunately 15-25% of patients fail to respond. The aim of this study was to examine whether multichannel electromyogaphic mapping improved outcomes in a cohort of antibody-negative onabotulinumtoxinA non-respo...
متن کاملSensory trick phenomenon improves motor control in pianists with dystonia: prognostic value of glove-effect
Musician's dystonia (MD) is a task-specific movement disorder that causes loss of voluntary motor control while playing the instrument. A subgroup of patients displays the so-called sensory trick: alteration of somatosensory input, e.g., by wearing a latex glove, may result in short-term improvement of motor control. In this study, the glove-effect in pianists with MD was quantified and its pot...
