Subjective visual vertical refers to an individual's ability to indicate what, in his or her opinion, is a perfectly vertical line in specific experimental conditions. Although the otolith organs play a key role in the perception of verticality, the contribution of other sensory systems, e.g. the visual and proprioceptive systems, cannot be overlooked. The(More)
Our study examined the posture of 15 patients who had sustained a simple unilateral or bilateral fracture of the condylar head of the mandible as a result of sports or traffic accidents. Following preliminary testing of vestibular function, the patients underwent balance testing: Romberg test with eyes closed (EC), Romberg EC and bite test (ECBT), EC and(More)
Clinico-instrumental criteria to reliably detect simulated vertigo remain to be defined. Computed dynamic posturography (Equitest) has been used to identify additional factors to distinguish simulated, from real vertigo. The present study population comprised 23 normal subjects and 16 patients with documented vestibular impairment. Normal subjects were also(More)
The Authors evaluated patterns of click-evoked otoacoustic emissions (EOE) in a group of 184 patients exposed to noise in their working environment. The aim of the study was to detect changes in EOE patterns in this group compared to the EOE of healthy subjects. The clinical history of each subject was recorded and otoscopy, pure tone audiogram and(More)
Auditory brain-stem responses (ABRs) were studied in 66 subjects with severe head trauma. Middle latency responses (MLRs) were also recorded in 22 of them. Patients were carefully selected to avoid conditions such as pre-existing or acute deafness, hypothermia or ethanol intoxication. In order to evaluate the usefulness of potentials in predicting recovery,(More)
