The pharmacodynamic effects of Risperidone on the vestibular system were assessed via dynamic computed posturography in 12 healthy subjects (6 male). Subjects were administered 2 mg, orally, of Risperidone and assessed on the NeuroCom® Balance Master© system under varying conditions. The vestibular response was deductively quantified by first assessing balance with a static force plate and eyes closed (Condition 2), and then assessed on a dynamic force plate with eyes closed (Condition 5). On average, Condition 2 scores were 24.46 points higher than Condition 5 scores (95% CI [20.973, 27.957]). A Pearson correlation between scores in Condition 2 and 5 showed a significant, moderate positive correlation (r = .487, p <.001). A trend analysis showed the effect of time, post-dose, on equilibrium score to be linear in nature (p < .001). In conclusion, some, but not all, of the subjects involved in the study experienced diminished vestibular control after administration of Risperidone; this may be due to phenotypic differences or learning effects.

A total of forty probands were divided into 3 groups according to the sports activity and the history of ACL injuries. Volunteers underwent examination of bipedal and monopedal standing on a stabilometric platform using a foam pad. We chose three types of secondary task, which we tested first at probands in a sitting position. Subsequently, we combined them with a bipedal and monopedal stance on a foam mat. In secondary tests, latency of response and error rate were measured. Our results show that the combination of a postural challenging situation with a secondary task significantly more affects performance in the sensory-cognitive task than the...

L'exercice permet l'acquisition et l'intégration de nouvelles habiletés motrices propres à la nature de l'activité considérée. L'exercice est également un facteur de risque de lésions et semble altérer temporairement la fonction d'équilibration. Cependant, les mécanismes physiologiques et physiopathologiques et leurs conséquences sur la fonction d'équilibration sont encore mal connus. Ce travail, pour lequel le cyclisme a été utilisé comme modèle neurosensoriel, visait à évaluer les éventuelles modifications des stratégies sensori-motrices physiologiques et compensatoires de la fonction d'équilibration en fonction du type d'exercice et de perturbations de l'homéostasie.Les stratégies sensori-motrices de routiers et de vététistes et celles des effets d'une déshydratation induite par un exercice ont été évaluées par posturographie. De plus, la prévalence de vertiges après compétitions ou entraînements a été évaluée par questionnaire chez des routiers et des descendeurs (spécialistes du vélo tout terrain descente). Pour assurer la fonction d'équilibration, les vététistes, qui pratiquaient le plus de VTT, utilisaient principalement les informations proprioceptives. Les routiers et les vététistes, qui pratiquaient le plus le cyclisme sur route, utilisaient davantage les informations visuelles. La déshydratation induite par l'exercice altérait temporairement le contrôle postural. Plus la déshydratation était importante, moins les informations vestibulaires étaient requises. Les vertiges survenaient couramment après la pratique du cyclisme et, en particulier, en VTT descente. L'épuisement a été rapporté comme un déterminant important des vertiges en cyclisme sur route alors que les accélérations-décélérations brusques et les chutes ont été rapportées comme déterminants des vertiges en VTT descente.La différence d'organisation sensorielle entre les vététistes et les routiers peut être expliquée par des processus adaptatifs élaborés à partir des stimulations environnementales et des spécificités techniques de ces disciplines. Bien que la fatigue musculaire puisse expliquer les altérations posturales à la suite d'un exercice, les modifications de l'homéostasie des liquides vestibulaires peuvent également diminuer le poids de l'information vestibulaire dans la régulation de l'équilibration. Les mécanismes physiopathologiques générant des vertiges peuvent être liés à des modifications homéostatiques induites par l'effort en cyclisme sur route. En VTT descente, les accélérations-décélérations (incluant les chutes), auxquelles la tête est soumise, peuvent générer des dysfonctionnements des structures vestibulaires, en particulier des organes otolithiques / Exercise leads to the acquisition and the integration of new motor skills specific for the type of practiced activity. Exercise is also a risk factor for injuries and seems to transiently alter the balance function. Nevertheless, physiological and pathophysiological mechanisms and their consequences on balance function still remain unclear. This work, which used cycling as a neurosensory model, aimed to evaluate the possible changes of physiological and compensatory balance-related sensory-motor strategies in function of the type of exercise and homeostatic perturbations. Road cyclists? (RCs) and mountain bikers? (MTBs) sensory-motor strategies were evaluated by posturography as well as the effects of exercise-related dehydration. Moreover, the prevalence of vertigo after competitions or training sessions was investigated by a questionnaire in RCs and downhill mountain bikers (MTBsDh).Balance-related visual information was better used by RCs and MTBs, who mainly practised road cycling. Somesthetic information was better used in MTB, who mainly practiced mountain biking. Exercise-related dehydration transiently altered postural control. The more severe the dehydration, the lower was the use of vestibular information. Vertigo commonly occurred after the practice of cycling, particularly in downhill mountain biking. Exhaustion was reported as a crucial factor for vertigo by RCs, whereas for MTBs it was sudden accelerations-decelerations and falls.The difference in sensory organisation between MTB and RC could be explained by adaptive processes elaborated from environmental stimulations and technical specificities of these disciplines. Even though muscular fatigue could explain the exercise-induced alterations of postural performances, vestibular fluid modifications may also be involved by their influence on intralabyrinthine homeostasis, lowering thus the contribution of vestibular information on balance control. The pathophysiological mechanisms generating vertigo might be an effort-related disturbance of homeostasis in RCs. In MTBsDh, the accelerations-decelerations (including falls), to which the head is subjected, might generate dysfunction of peripheral vestibular structures, particularly the otolith organs

The aim of this diploma thesis is to evaluate spatial orientation in the patients after vestibular schwannoma surgery. In the theoretical part, there are summarized the facts about vestibular system; there is described the clinical picture of unilateral vestibular dysfunction and the field of vestibular schwannoma and spatial orientation in general. In the practical part, we performed the investigation of the spatial orientation using the Blue Velvet Arena System and posturography using the platform Balance Master® System. The purpose of the practical part was to find out, whether unilateral vestibular dysfunction in patients after vestibular schwannoma surgery has the impact on spatial orientation and to what extent is the postural stability influenced in patients identified for surgery and in patients after vestibular schwannoma surgery.

Postural stability is necessary for all human activities. Management od postural control is provided especially by central nervous system. For management are essential afferent information from vestibular, visual and somatosensory system. Modification of any of these inputs could have influence postural stability. Changes of exteroceptive perception can be achieved by the application of kinesio tape. Kinesiotaping is currently very popular therapeutic method, which is attributed to the wide range of effects. In the theoretical part of this thesis are described these effects, including the results of scientific studies that are engaged in verify the effects. Experimental part of this thesis was focused on the objectification of any changes of postural stability after application of kinesio tape on dorsal and ventral side of the trunk in healthy individuals without injury or other disorders. For the examination were used two tests of Balance Master® System, the modified clinical test of sensory interaction on balance and the test limits of stability. The results were satistically evaluated at the level α = 0.05. Due to kinesio tape were observed no siginificant changes in the mean sway velocity of center of gravity. There were also found no significant changes of parameters that evaluate the transmission of...

Introduction: Spinocerebellar ataxia (SCA) is currently defined as a group of diseases with progressive cerebellar syndrome, which manifests distinctively by ataxic stance and gait. In patients with SCA, deterioration of postural control occurs due to changes of pathophysiological degenerative nervous system. Control of postural stability is significantly influenced by somatosensory afferentation of soft tissue of foot. The work objective is to determine the effect of deep foot massage on postural stability in the group of patients and to compare obtained results with experiments without deep foot massage. Methods: Seven patients of the Clinic Rehabilitation at the Faculty Hospital, Prague Motol (average age 51.9 ± 13.9 years, 5 men, and 2 women) with SCA and clinical signs of cerebellar ataxia were participated in this study. All patients were examined using posturography before and after application of deep foot massage. Measurements were conducted on a firm surface, foam pad with open and closed eyes. Length of COP trajectory, COP area and COP velocity were measured. Results: Significantly lower values of the length and COP velocity were found on the foam pad with closed eyes, when the deep foot massage was applied. Experiments without applications of the deep foot massage did not show any...
