Dynamic head‐neck stabilization in cervical dystonia
Postural Strategies and Sensory Integration: No Turning Point between Childhood and Adolescence
The results reported here confirmed the predominance of vision and the gradual mastery of somatosensory integration in postural control during a large period of ontogenesis including childhood and adolescence.
Plasticity of static graviceptive function in patients with cervical dystonia
Sensorimotor Control in Dystonia
This overview of relevant research regarding sensorimotor control in humans with idiopathic dystonia attempts to frame the dysfunction with respect to what is known regarding motor control in patients and healthy individuals.
Focal dystonia in musicians: linking motor symptoms to somatosensory dysfunction
It is argued that an enhanced understanding of how a primary sensory deficit interacts with mechanisms of sensorimotor integration in MD provides helpful insights for the design of more effective behavioral therapies.
Cervical dystonia: etiology and pathophysiology.
Cervical Dystonia Is Associated With Aberrant Inhibitory Signaling Within the Thalamus
Findings support that aberrant inhibitory signaling within the thalamus contributes to the pathophysiology of cervical dystonia and suggest that an inadequate ability to compensate for the loss of GABA through upregulation of GABAA receptors may underlie more severe symptoms.


Deficits and recovery of head and trunk orientation and stabilization after unilateral vestibular loss.
The results suggest that unilateral Vestibular loss leads to a postural syndrome similar to that described previously for various animal species and support the notion that vestibular compensation relies on visual cues whose substitution role gradually decreases after UVN.
Differential approach to strategies of segmental stabilisation in postural control
The present paper attempts to clarify the between-subjects variability exhibited in both segmental stabilisation strategies and their subordinated or associated sensory contribution, and provides evidence for a new interpretation of the visual field dependence–independence dimension in both spatial perception and postural control.
Voluntary head stabilization in space during trunk movements in weightlessness.
Effect of gaze on postural responses to neck proprioceptive and vestibular stimulation in humans
The prominent effect of gaze in reorienting automatic postural reactions indicates that both neck proprioceptive and vestibular stimuli are processed in the context of visual control of posture and points out the importance of a viewer‐centred frame of reference for processing multisensory information.
Visual control of balance in cerebellar and parkinsonian syndromes.
The results indicate that cerebellar lesions seem largely to spare the visuopostural loop and also spare the ability to shift from a visual to a proprioceptive control of postural sway, which suggests that basal ganglia participation in posture is concerned with the reweighting of the various sensorimotor loops controlling posture in the process of adapting to novel situations.
Instability of gaze during locomotion in patients with deficient vestibular function
Testing of patients with vestibular symptoms should include stimuli corresponding to the rotational head perturbations that occur during locomotion; such head rotations have nonpredictable characteristics and a frequency range of 0.5 to 5.0 Hz.
Abnormal interaction between vestibular and voluntary head control in patients with spasmodic torticollis.
It is concluded that voluntary interaction with the vestibulo-collic reflex is disrupted in patients with spasmodic torticollis, a finding which corroborates the patients' aggravation of their symptoms by head or body perturbations.
Postural responses to vibration of neck muscles in patients with idiopathic torticollis.
The results suggest that neck proprioceptive input retains local postural functions in ST, however, it is relatively ignored in the context of the whole body postural control and spatial orientation.
Altered sensorimotor integration in Parkinson's disease.
The results suggest an abnormal influence of afference on corticomotor excitability in Parkinson's disease may be related to abnormal sensory input, a defective integrative unit or an inappropriate motor response.
