Objectification of the Test 3F - dysarthric profile based on acoustic analysis
Bezůšek, Marek ; Galáž, Zoltán (referee) ; Mekyska, Jiří (advisor)
Test 3F is used to diagnose the extent of motor speech disorder – dysarthria for czech speakers. The evaluation of dysarthric speech is distorted by subjective assessment. The motivation behind this thesis is that there are not many automatic and objective analysis tools that can be used to evaluate phonation, articulation, prosody and respiration of speech disorder. The aim of this diploma thesis is to identify, implement and test acoustic features of speech that could be used to objectify and automate the evaluation. These features should be easily interpretable by the clinician. It is assumed that the evaluation could be more precise because of the detailed analysis that acoustic features provide. The performance of these features was tested on database of 151 czech speakers that consists of 51 healthy speakers and 100 patients. Statistical analysis and methods of machine learning were used to identify the correlation between features and subjective assesment. 27 of total 30 speech tasks of Test 3F were identified as suitable for automatic evaluation. Within the scope of this thesis only 10 tasks of Test 3F were tested because only a limited part of the database could be preprocessed. The result of statistical analysis is 14 features that were most useful for the test evaluation. The most significant features are: MET (respiration), relF0SD (intonation), relSEOVR (voice intensity – prosody). The lowest prediction error of the machine learning regression models was 7.14 %. The conclusion is that the evaluation of most of the tasks of Test 3F can be automated. The results of analysis of 10 tasks shows that the most significant factor in dysarthria evaluation is limited expiration, monotone voice and low variabilty of speech intensity.

The intervention of physiotherapy in the treatment of dysarthria after stroke
Nováková, Kateřina ; Bitnar, Petr (advisor) ; Roubíčková, Lenka (referee)
Stroke is the most comman cause of the speech disorders in adults. Dysarthria, as a motor speech disorder, is one of them. The treatement is based not only on vocal and articulatory exercices, but it requires the complex rehabilitation treatement. The benefit of the physiotherapeutic intervention beside speech therapy might be large. The treatement of the muskuloskeletal system allows to see the orofacial disorders in the context of the posture of the whole body. This work wants to make a view on the process of speech production and to describe relationship of the musculoskeletal system and speech. This work also summarises the basic informations about pathogenesis of dysarthria and particularly about the treatement. The swallowing disorders are also very comman complication of the stroke and occur very often with dysarthria. The aim of this work is to describe the specific role of the physiotherapy in the treatement of dysarthria and look for some possibility of the cooperation between physiotherapist and clinical speech therapiste. The form of the work is the research with case history. Powered by TCPDF (www.tcpdf.org)

Communication disability in patients with cerebral palsy and it's effect on communication and socialization of the individuals
Hálová, Barbora ; Korandová, Zuzana (advisor) ; Horynová, Jana (referee)
This Master's thesis explores how developmental dysarthria and communication disability effect the socialization and communication abilities of people with cerebral palsy. The thesis is divided into two primary sections: theoretical and empirical. The theoretical part is divided into four sections (cerebral palsy, disrupted communication abilities in people with cerebral palsy, dysarthria, communication and socialization in people with cerebral palsy). The next part of the work presents the analysis of dysarthria and disrupted communication abilities effect of the socialization and communication abilities in people with cerebral palsy. The empirical section is based on original research, primarily employing qualitative methods, namely semi-structured interviews. I interviewed six individuals all of whom are affected by cerebral palsy and developmental dysarthria. Research goals included how disrupted communication skills, known as developmental dysarthria, affect the individuals' communication and socialization skills, how it affects them in daily situations, what the main hallmarks of these situations are, what these situations have in common and how developmental dysarthria affects the individuals' motivation towards socializing. The results showed that the degree to which disrupted...

Mmultidisciplinary care with the focus on speech and swallowing disorders provided to patients with amyotrophic lateral sclerosis
Černá, Adéla ; Klenková, Jiřina (advisor) ; Horynová, Jana (referee)
The diploma thesis is focused on the issue of acquired dysarthric and swallowing disorders in amyotrophic lateral sclerosis and on multidisciplinary care provided to patients with this disease. Theoretical part of the thesis is divided into three chapters. The introductory chapter presents a summary of current knowledge about amyotrophic lateral sclerosis (ALS). The following two chapters are dedicated to dysarthria and dysphagia and their specifics in ALS. The practical part of the diploma thesis is represented by the fourth chapter which incorporates a research survey focused on multidisciplinary care provided to patients with ALS. The primary aim of the research is to evaluate the multidisciplinary care provided to two selected patients with ALS with a focus on speech and swallowing disorders. The secondary objectives of the research relate to the evaluation of the extent of acquired dysarthric and swallowing disorders of these patients, providing a comprehensive overview of the course and content of the provided care and gathering information to create information brochure for patients with ALS and caregivers. The research approach to achieve the determined objectives of the research survey is creation of case studies using qualitative methods of data collection, which is a structured interview...

Pathophysiological mechanisms of the pallidal deep brain stimulation in dystonic syndromes
Fečíková, Anna ; Jech, Robert (advisor) ; Nevrlý, Martin (referee) ; Škorvánek, Matej (referee)
Deep brain stimulation (DBS) of the globus pallidus internus (GPi) is an effective symptomatic treatment for pharmacoresistant dystonic syndromes. The relationship between grey matter volume and intracortical inhibition of the primary motor cortex (MI) in regard to the effectiveness and the state (ON/OFF) of GPi DBS was analysed in the first study. The grey matter of chronically treated patients showed hypertrophy of the supplementary motor area and cerebellar vermis whereas this difference was more significant in patients with a better clinical outcome. The grey matter of the cerebellar hemispheres of the patients showed positive correlation with the improvement of an intracortical inhibition which was generally less effective in patients regardless of the GPi DBS state. Moreover, we showed the same level of SICI in the good responders as in the healthy controls, while in non-responders was the SICI decreased. In the second study, by using paired associative stimulation (PAS) we studied the influence of primary somatosensory cortex (SI) on the MI excitability in dystonia in regards to the effectiveness of GPi DBS. SI PAS decreased the MI excitability in the GPi DBS ON state while switching the stimulation off decreased an inhibitory effect of SI on MI excitability. Non-responders showed a...

Procházková, Eva ; Klenková, Jiřina (advisor) ; Kopečný, Petr (referee)
This diploma thesis presents an analysis of speech impairments accompanying Parkinson's disease. This paper is divided into two sections - theoretical and practical. The first section gives a brief overview of available Czech and foreign literature and articles about this neurodegenerative disease. The section examines the questions of its aetiology, symptomatology, diagnostics and treatment. There can be found also a description of speech impairment connected with this disease, which is mainly hypokinetic and hyperkinetic dysarthria and dysphagia. It also deals with the problem of other limitations in communication such as facial bradykinesia or speech intelligibility. In the last chapter of theoretical part is described speech therapy and intervention with the emphasis on therapy, diagnostics and the effects of pharmacology an non-pharmacological treatment such as deep brain stimulation on speech performance in Parkinson's disease. The research part analyses speech impairment of people with Parkinson's disease. The aim of this diploma thesis was examination of this speech impairment using the Test 3F: Dysarthria profile and patient's own perception of this specific speech disorder. In this paper are presented eight case studies focusing on speech of clients with Parkinson's disease. The results...
