Objective: to analyze the oscillatory velocity of the pressure center (COP) of the body in different sensorial contexts in patients with Ménière’s Disease. Methods: 15 subjects, 02 males and 13 females, aged 28-71 years, who presented defined diagnostic of Ménière’s Disease were submitted to evaluation of the modified clinical test of sensorial integration (mCTSIB) by […]
Between main postural reflexes, there are tonic labyrinth reflexes generated in otolith system as a results of earth gravity. The neck extensors action is a result of these reflexes and the medullar structures are their centers. It is known that the rigidity of decerebrated animals is caused by the fastigial nucleus damage and that this […]
There are different stimulation methods for investigation of the vestibular system. In addition to optokinetic, galvanic and neck vibration tests the most wide-spread is the caloric stimulation. These listed methods cause not only vestibular but other different effects on the central nervous system (CNS) (acustic, tactile and nociceptive). The authors using positron emission tomograhy (PET) […]
Rationale: Several reports have shown that the direction of the postural responses induced by vestibular stimulation is affected by the neck and torso position. The aim of the study was to investigate whether the postural responses to vibratory proprioceptive stimulation of the calf muscles are affected by the head position and thus by proprioceptive and […]
Hockey is a contact team game played by international rules. According to the rules the hockey players while struggling for the puck are allowed to perform various co-operative and confrontational actions. Hockey is the faster team game. Players produces high velocities by skating using muscles power (about 30 Km/h). The game requires very fine eye-hand-legs […]
Balance function aims to achieve a stable relationship between oneself and the sorrounding world, the environment. The result is spatial stabilization, which means that, when perceiving this sorrounding, one has the impression that it is stable. During each movement of the body and/or of the head the visual otrientation of space has to be stabilized. […]
Since many years we are using the local positioning system of ultrasound computer cranio-corpo-graphy (US-COMP-CCG). The patient is carrying a helmet with 2 ultrasound markers and a shoulder fixation with 2 other ultrasound markers. A computer unit is triggering the ultrasound impulses. Backwardly and above the patient is the ultrsound receiver unit containing several ultrasound […]
Patients with definite multiple sclerosis frequently suffer from vestibular disorders due to a vestibulo-oculomotor and vestibulospinal systems involvement. The vestibulospinal reflexes in these subjects can be well investigated through the vestibular evoked myogenic potentials recording. These potentials, evoked by the acoustic stimulation of the saccular macula and mediated by vestibulocollic reflex pathway, are recorded using […]
L’ equilibrio dell’ uomo e’ una funzione complessa che consente la stabilizzazione delle immagini sulla retina durante il movimento della testa e/o del corpo nello spazio (coordinazione oculomotoria) e l’ opposi-zione alla forza di gravita’ realizzando quindi sia la stazione eretta (coordinazione d’equilibrio statico) sia il movimento nell’ ambiente (coordinazione d’equilibrio dinamico). Contemporaneamente alla coordinazione […]
PURPOSE: to evaluate head stabilization in pitch plane in patients with different kinds of imbalance, when standing over firm and movable surfaces. MATERIAL: STATITEST multi-segments platform for recording and computing the postural adjustments at different body levels, detected by two captors placed on the head and hip, in four situations – eyes open and closed […]
