Temporomandibular disorders (TMD) are the major disorders of the cranio-cervicomandibular system. They usually result in alterations of human body posture. Temporomandibular joint disorders (TMD) lead to adaptations in certain body structures that minimizes patient’s pain and also reconfigures musculoskeletal stress zones. These adaptations if not corrected may cause deviations in normal body p...

Postural disturbances in advanced Parkinson's disease are less responsive to therapy than other cardinal motor signs. The vestibulocollic reflex represents one brain-stem neuronal circuit involved in postural adjustments. The objective of this study was to investigate the vestibulocollic reflex in parkinsonian patients and the effects of subthalamic stimulation and dopa by recording vestibular-...

Aberrant vestibular nuclear function is proposed to be a principle driver of limb muscle spasticity after stroke. We sought to determine whether altered cortical modulation of descending vestibulospinal pathways post-stroke could impact the excitability of biceps brachii motoneurons. Twelve chronic hemispheric stroke survivors aged 46-68 years were enrolled. Sound evoked biceps myogenic potenti...

OBJECTIVE In response to loud clicks, a vestibular evoked potential can be recorded from sternocleidomastoid muscles, called "click evoked myogenic potential" (CEMP). This paper reports on the usefulness of CEMP in the differential diagnosis of acute vertigo of presumed vestibular origin. METHODS CEMP was examined in 40 patients with acute vertigo of vestibular origin (26 with acute periphera...

Vestibular evoked myogenic potentials (VEMPs) are myogenic responses induced by stimulation of the saccular macula by intense sound stimuli. The responses are recordable from the sternocleidomastoid (SCM) muscles. We recorded VEMPs from normal subjects (up to three times in each subject) to identify: i) the best recording procedures, ii) the reliability, and iii) the normal limits for both indi...

Vestibular system, which consists of structures in the inner ear and brainstem, plays a vital role is body balance and patient well-being. In recent years, modulating this system by vestibular stimulation techniques are reported to be effective in stress relief and possibly patient's emotional well-being. Emotions refer to an aroused state involving intense feeling, autonomic activation, and re...

A part from cervical pains, dizziness is the most common complaint after whiplash injury of the neck. Dizziness was attributed to lesions of the peripheral vestibular organ and the cervical proprioceptive system and to central pathways in the brainstem, the cerebellum, and the hypothalamus. Soft-tissue hemorrhage, swelling and ruptures of neck muscles and ligaments, and brain edema and hemorrha...

In an attempt to diminish the intensity of vertigo, this study was designed to reduce the imbalance between the vestibular system on the two sides. By rotating the subjects with a string-activated rotating chair in opposite direction of the dominant side, the dominant side would be inhibited and simultaneously the subordinate ide would be stimulated. Eight patients with vestibular vertigo c...

Research conducted in the past 4 years has shown that the avian vestibular system retains the capacity to generate hair cells postnatally. In the present paper we review information on postnatal proliferation and differentiation of hair cells in the avian vestibular system. In addition, we present preliminary accounts of recent experiments regarding regeneration of vestibular hair cells followi...

background chronic vestibular dysfunction is a frustrating problem in the elderly and can have a tremendous impact on their life, but only a few studies are available. vestibular rehabilitation therapy (vrt) is an important therapeutic option for the neuro-otologist in treating patients with significant balance deficits. objectives the purpose of this study was to assess the effect of vestibula...
