Influence of temporomandibular dysfunction on head position
Veselá, Nikola ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
Dysfunction in the temporomandibular joint appears to varying extents, depending on the chosen criteria, in at least half of the world's population. Altered afferentation from the orofacial area (for example due to dysfunction in the temporomandibular joint) can, according to research, have an effect on the position of the head, cervical spine and postural stability. However, the issue of the influence of temporomandibular dysfunction on head position or postural stability is still not sufficiently explored and conflicting opinions appear in the literature. The aim of this thesis is to reveal the correlation between dysfunction in the temporomandibular region and changes in postural stability, head position and subjective visual vertical. In the theoretical part, the current knowledge of the influence of the temporomandibular region on the surrounding structures and body posture will be presented using research. The aim of the practical part will be to investigate to what extent and in what time modulated afferentation from the orofacial area will affect the posture, head position and possibly also the subjective perception of the vertical. Measurements will take place on a stabilometric platform, using the Bucket method and further using QR codes and a computer program. The results will be...

Vestibular Function in Cochlear Implant Patients
Matějková, Michaela ; Čakrt, Ondřej (advisor) ; Koutná, Sára (referee)
Hearing loss is the most common sensory impairment. More than 5 % of the world's population suffers from disabling hearing loss, which affects approximately one third of people over the age of 65. In those cases where hearing aids are not a sufficient solution to these difficulties, cochlear implantation is the standard treatment. It replaces, at least in part, the function of the hair cells that are no longer able to stimulate the primary auditory neurons. However, there are concerns about the potential risk of impaired vestibular function and the development or worsening of non-vestibular problems such as tinnitus, vertigo and orofacial disorders. Aims: To provide a theoretical summary of fundamental information on the vestibular system and cochlear implantation and to assess vestibular and non-vestibular function after cochlear implantation and the impact of any abnormalities on patients' quality of life. Methods: All of the participants underwent subjective visual vertical examination, platform posturography and completed five questionnaires - Dizziness Handicap Inventory, Tinnitus Handicap Inventory, Facial Disability Index, Beck's Anxiety Inventory and Beck's Depression Inventory. Overall and partial results from platform posturography examinations were compared with a control group of...

Perception of subjective visual vertical
Radvanská, Edita ; Čakrt, Ondřej (advisor) ; Kučerová, Klára (referee)
Postural balance system is a multisensory-organized complex using afference of exteroceptors, enteroceptors, proprioceptors and the visual and the vestibular system. The utriculus and the sacculus are otolith organs placed in the vestibular labyrinth and they are capable of recognizing the direction of gravity. Their function is crucial for keeping postural stability during stand and walk. The ability to recognize the geophysical vertical is failing if the vestibular system is impaired. There are the subjective visual vertical (SVV), the subjective postural vertical (SPV) and the subjective haptic vertical (SHV) which can be tested in humans. This study is interested in SVV, its pathophysiology and measuring. We are comparing the accuracy of measurement of SVV by the Bucket method and a mobile application Visual Vertical in healthy subjects in our experiment.

The evaluation of vestibulospinal and vestibuloocular reflex in patients during early postoperative period after vestibular schwannoma resection
Markvartová, Anna ; Čakrt, Ondřej (advisor) ; Chovanec, Martin (referee)
The thesis deals with the issues of balance disorders in patients after vestibular schwannoma surgery. The aim of this thesis is to evaluate the effect of targeted rehabilitation with biofeedback on balance disorders and subjective visual vertical compensation. During the period of one year, a group of 20 vestibular schwannoma patients were examined and treated in University Hospital Motol. The compensation of vestbuloocular refex was assessed by a tilt of subjective visual vertical. The level of vestibulospinal compensation was determined according to score of the Activities-Specific Balance Confidence Scale. Patients were examined before the surgery, after the surgery and after the rehabilitation. The Homebalance system, developed by Support center for application outputs and spin-off companies at the 1st Faculty of Medicine, Charles University in Prague, branch office in Kladno, was used for the therapy with visual biofeedback. Another aim of this thesis was to monitor the effect of vestibular prehabituation with ototoxic gentamicin application two months before surgery. The statistical analysis of data proved in the case of subjective visual vertical tilt a significant increase of deviation after surgery and a decrease after rehabilitation. According to the ABC questionnaire the confidence of...

Evaluation of head position - children with idiopathic scoliosis
Dvořáčková, Štěpánka ; Kučerová, Klára (advisor) ; Šafářová, Marcela (referee)
Idiopathic scolios (IS) is one of the most common structural spinal deformities. Patients with idiopathic scoliosis have altered posture due to scoliosis. The aim od the study was to evaluate the position of the head in children with IS and to compare the results with a control group of healthy children. The position of the head was evaluated by the method of kinematic analysis from digital photographs, where we compared the coronal head tilt and the coronal shoulder angle between the two groups. Furthermore, the measurement of the subjective visual vertical was pearformed using Bucekt metod. Both of these measurements were performed in 10 children with IS (age 12,2 ± 2,4, mean ± SD; Cobb angle 14,9˚ ± 8,8˚ SD) and the group od 10 healthy children (age 13,9 ± 2,5). Based on these measurements, we evaluated three hypotheses. We came to the conclusion that both groups have comparable average deviations from the central position of the head and shoulders, but in the group with IS there was higher variance of values. In the group with IS, in seven patients the sides of the SVV tilt and the head tilt do not match.

Impact of cochlear implant on vestibular function in adult patients
Ištoková, Lucie ; Kučerová, Klára (advisor) ; Čakrt, Ondřej (referee)
Bibliographic identification IŠTOKOVÁ, Lucie. The influence of cochlear implant on vestibular function in adult patients. Prague: Charles University, 2nd Faculty of Medicine, Department of Rehabilitation and Sports Medicine, 2020. 58 p., Appendices. Thesis supervisor Mgr. Klára Kučerová. Abstract Severe hearing loss is standardly treated by cochlear implantation. Considering the anatomical proximity and interconnection to the vestibulocochlear nerve, it is possible to influence vestibular functions. The aim of this diploma thesis is to evaluate the effect of unilateral cochlear implantation on postural stability and vestibular function in adult patients with severe hearing loss caused postlingually. Eleven patients aged 28-72 were examined the day before surgery, the day after surgery, and on average 25 days after surgery. The evaluation consisted of short-form Dizziness Handicap Inventory (DHI), Timed Up and Go testing (TUG), static stabilometry and the perception of the subjective visual vertical (SVV) static and dynamic. Significant deterioration of TUG and SVV was recorded particularly immediately after surgery. In dynamic SVV, especially, when the field of view rotated to the left. Considerable results in stabilometry were only when standing on a hard surface with eyes closed. Improvements in TUG, SVV...

Perception of verticality in patients with developmental coordination disorder
Žídek, Radim ; Čakrt, Ondřej (advisor) ; Demeková, Júlia (referee)
Bibliographic identification Author's first name and surname: Bc. Radim Žídek Title of the master thesis: Perception of verticality in patiens with developmental coordination disorder Department: Department of Rehabilitation and Sports Medicine, 2nd faculty of medicine, Charles University and FN Motol Supervisor: PhDr. Ondřej Čakrt, Ph.D. The year of presentation: 2017 Annotation: Developmental coordination disorder is typical for poor motor learning and motor coordination that cannot be related to any neurological or mental disease. The exact reason of it stays still unknown. There are theories that say that dysfunctional collaboration of afferent systems causes developmental coordination disorder. Thanks to afferent systems a human organism is able to perceive different modalities. One of the modalities is a perception of verticality. In theoretical part of this thesis we summarized information about developmental coordination disorder and postural and balance control. In experimental part we tested 35 pupils of primary school (age 13-15). Using MABC-2 we classified the pupils into children with and without predispositions for developmental coordination disorder. Then we tested their ability of perceiving subjective visual and subjective haptic verticality. According to statistical evaluation there is no...

The effect of targeted rehabilitation on vestibular compensation in patients after vestibular schwannoma resection.
Holá, Irena ; Čakrt, Ondřej (advisor) ; Čada, Zdeněk (referee)
The thesis deals with the evaluation of the impact of preoperative application of gentamicin on vestibular compensations of patient after vestibular schwannoma surgery. The trial involved 32 patients with diagnosed vestibular schwannoma and hospitalized with the indicated for neurosurgical resection at the University Hospital Motol. Ototoxic gentamicin was transtympanically applied to ten of these patients two months before their surgery. After the surgery the patients underwent a rehabilitation program based on the visual biofeedback using the Homebalance system. To evaluate the vestibular compensation the subjective visual vertical measurement and the Dynamic Gait Index standardized walking test were used. In total, each patient performed three examinations: before the surgery, after the surgery and before the end of hospitalization. Statistical analysis of the measured data showed the statistically significant increase tilt of subjective visual vertical and the decrease in the overall score of Dynamic Gait Index after surgery. Reduction in the subjective visual vertical tilt and the overall score of Dynamic Gait Index after rehabilitation has not been proven to be statistically significant. Any statistically significant difference was found between the group of patients treated by gentamicin and...
