Linguistic processing and performance in articulation-disordered subgroups of language-impaired children.

The linguistic and dichotic listening performances of three groups of nine children were studied. The groups were divided as follows: (1) Language-disordered children whose articulatory errors were primarily omissions; (2) language-disordered children whose articulatory errors were primarily substitutions; (3) communicatively normal children. All subjects participated in articulation testing, imitative language tests, analysis of a spontaneous language sample, and a dichotic word task. The articulatory omission group differed significantly from the substitution group on the imitative language test but not on the developmental sentence analysis. All groups demonstrated a right ear advantage, suggesting left hemispheric processing of the dichotic stimuli. The results of the present study and prior research are discussed in terms of possible sources of variability.

[Articulation disorders in aphasia. Considerations in several clinical cases].

Selective deficit of verbal output not associated to other anomalies of language, represents a syndrome in which articulatory as well as linguistic aspects can be independently affected. The critical lesion for pure articulatory deficit appears to involve left prerolandic cortico-subcortical structures. Nevertheless, in relation to individual differences in cerebral organization, damage in these structures can be responsible for a simultaneous deficit of articulatory and linguistic mechanisms.

Atrophy of the tongue with persistent articulation disorder in myasthenia gravis: report of 10 patients.

Ten patients with atrophy of the tongue, from a group of 752 with generalized acquired myasthenia gravis (MG), were studied. Tongue atrophy developed late in the majority of patients and was accompanied by tongue paresis (70% of the cases) and eventually associated to atrophy of other muscles of the palate, especially the uvula. All the patients exhibited severe forms of MG with bulbar involvement, mainly persistent dysphonia and dysphagia, almost always refractory to treatment. There is no correlation among atrophy of the tongue, sex, and thymus pathology. There is correlation between severeness of symptoms and early, persistent and treatment refractory dysphonia and dysphagia.

[Articulation disorder as the initial manifestation of facioscapulohumeral muscular dystrophy in childhood].

A five year old boy who had received logopedic treatment for more than two years was seen as an outpatient because of speech retardation. He presented with myopathic face, incomplete closure of both lids and severe weakness of facial muscles, bilateral winging of scapulae and hyperlordosis. Extraocular and pharyngeal muscles were not affected. Motor and sensory nerve fibre conductions and electromyography were within normal limits. CPK was moderately elevated (320 U/I). Muscle biopsy of right deltoid muscle revealed unspecific myopathic changes. The patients brother aged 7 also presented with facial weakness, elevated CPK and neurogenic changes in EMG of deltoid muscle. Both parents were clinically and electrophysiologically unremarkable. Although problems to speak distinctly are usually not the first manifestation, we found in this family facio-scapulo-humeral muscular dystrophy.

[Ultrasonography of the tongue in the rehabilitation of speech articulation disorders].

There has been presented a possibility of application of ultrasound examination of the tongue in the diagnosis and phoniatric rehabilitation exemplified by exposing shapes of the lateral surface of the tongue during correct articulation of the Polish vowels and articulatory exercises in the system of visual feedback in a normally hearing child and in a deaf one.

The use of time-expanded speech as an aid in the diagnosis of articulation disorders.

The recordings of 20 speech defective speakers' readings of a standard prose passage were presented to 36 student speech clinicians under three listening conditions: (1) unaltered; (2) time expanded to 150% of the original recording time; and (3) time-expanded to 200% of the original recording time. Results of their evaluations indicate that the expanded versions of the recordings elicited more accurate evaluations by the student clinicians. Implications of these findings concerning the possible usefulness of time-expanded speech as an aid in the training of listening skills in student speech clinicians are discussed.
