18 Diagnosis and Differential Diagnosis of Acquired Motor Speech Disorders (Dysarthria, Dyspraxia)
摘要
After discussion of general aspects of evaluation of verbal communication, specific assessment tools are presented to examine motor speech disorders highlighting informal and formal approaches. Issues to evaluate nonverbal communication are indicated. Elements of the Speech Motor Examination Protocol are introduced in detail as a precondition to developing an individual plan of clinical speech therapy and further therapeutic interventions. Concerning the evaluation of oral motor skills, an exemplary scale is displayed. Requirements to develop and apply objective analyses of speech are presented. Anatomical and sensorimotor examination of the structures involved in speech production, perceptual assessment, assessment levels, tasks and outcome measures in motor speech disorders are elucidated. Instrumental techniques are introduced. Elements of a comprehensive neurological evaluation and laboratory examinations are considered. Techniques of neuroradiological imaging are discussed in detail. Symptomatic aspects are presented in respect of various neurological diseases, useful for the differential diagnosis of the various causes of apraxia and dysarthria. Electromyography is elucidated by many examples of neurological vocal fold motor disorders. The interpretation of the results of logopaedic/SLP examination is defined as a synopsis with the further findings of the multi-disciplinary rehabilitation team. Items of occupational therapy are presented.
