Subjective visual vertical in patient with BPPV
Svobodová, Klára ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
The perception of verticality may be affected by a disorder of the vestibular system. One of the causes of vestibular system pathology is benign paroxysmal positional vertigo (BPPV). Our study investigates the changes in the perception of verticality in patients with BPPV compared to the healthy population. Therapeutic positional maneuvers are used to treat BPPV. Using the positional maneuver, the otoconia are relocated from the semicircular canals back to the utricle. This thesis investigates the effect of therapeutic maneuver on the change in the perception of verticality. The theoretical part discusses the perception of verticality, types of verticality, pathology in the perception of verticality and the possibilities of its measurement. Most of the focus is on the description of subjective visual verticality (SVV). It also describes the vestibular system and discusses the BPPV. In the practical part, a set of ten patients and a control group are presented. Using statistical data processing, the result is to answer the hypotheses whether there is a difference in the perception of verticality between patients with BPPV and healthy subjects. It also addresses the question of whether the therapeutic maneuver will affect the perception of verticality in patients with BPPV. Verticality was measured...
Otolithic system disorders in patients with positional vertigo.
Jendrichovská, Lucia ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
One of the functions of the equilibrium system is to detect direction and action of the gravitional vector. The dysfunction of the equilibrium system is expressed by a change in the perception of the vertical axis. The aim of this work is to evaluate the function of the otolithic system by examining the subjective visual vertical (SVV) in patients with benign paroxysmal positional vertigo (BPPV). The theoretical part of the study deals with the anatomy and physiology of the inner ear, with focus on the etiopathogenesis, clinical presentation, evaluation and treatment of BPPV. Practical part of the study examined 5 patients who were diagnosed with BPPV. All patients had objective examination of the SVV by digital device. The optokinematic rotation of the enviroment in static and dynamic contidtions were monitored. After examination and input data recording, treatment was performed with an Epley repositioning maneuver. Re-evaluation of the SVV values were performed immediately after treatment maneuver. Measurements after the repositioning maneuver confirmed improvement of the SVV values in all subjects with BPPV.
