TL;DR: Results clearly favour the second type of procedure which in interaction with Bobath's technique proved able to bring the children from unintelligible to an acceptable level of functional speech.
Abstract: A 4-year longitudinal intervention was conducted with 10 young severely dysarthric children with cerebral palsy. Two procedures were implemented, each one for a period of 2 years. The first procedure centred on training the oral praxies, whereas the second one favoured a more functional approach based on voice and prosody training as well as parents' and school teachers' involvement. Bobath neurodevelopmental treatment was given throughout the 4-year period. Results clearly favour the second type of procedure which in interaction with Bobath's technique proved able to bring the children from unintelligible to an acceptable level of functional speech.

TL;DR: Oral diadochokinesis of alternating motion rates and velocity of narrative speech represent a possible additional prognostic parameter for the outcome of traumatic brain injury in diffuse axonal injury.
Abstract: Aim: To investigate dysarthria in severe traumatic brain injury following an acceleration/deceleration trauma and to correlate results with the severity of head trauma.Methods: Oral diadochokinesis by testing alternating (/pa/, /ta/and/ka/) and sequential motion rates (/pataka/and/tana/) and contextual speech, which comprises narrative speech and text reading, were examined in 15 patients in the chronic stage after severe closed head trauma with diffuse axonal injury. A possible influence of the severity of brain injury, expressed by the duration of post-traumatic amnesia, was examined.Results: Oral diadochokinesis of alternating motion rates and velocity of narrative speech were significantly reduced in traumatic brain injury. Both parameters correlated highly significantly with each other and correlated with the severity of brain injury described by the duration of post-traumatic amnesia. Reading speed was not comparable with narrative speech. Reading speed did not correlate with diffuse axonal injury b...

TL;DR: This study supports the existence of distinct presentations of dysarthria in patients with HD, which may be due to divergent pathologic processes.
Abstract: Objective Dysarthric speech of persons with Huntington disease (HD) is typically described as hyperkinetic; however, studies suggest that dysarthria can vary and resemble patterns in other neurologic conditions. To test the hypothesis that distinct motor speech subgroups can be identified within a larger cohort of patients with HD, we performed a cluster analysis on speech perceptual characteristics of patient audio recordings. Methods Audio recordings of 48 patients with mild to moderate dysarthria due to HD were presented to 6 trained raters. Raters provided scores for various speech features (e.g., voice, articulation, prosody) of audio recordings using the classic Mayo Clinic dysarthria rating scale. Scores were submitted to an unsupervised k-means cluster analysis to determine the most salient speech features of subgroups based on motor speech patterns. Results Four unique subgroups emerged from the cohort of patients with HD. Subgroup 1 was characterized by an abnormally fast speaking rate among other unique speech features, whereas subgroups 2 and 3 were defined by an abnormally slow speaking rate. Salient speech features for subgroup 2 overlapped with subgroup 3; however, the severity of dysarthria differed. Subgroup 4 was characterized by mild deviations of speech features with typical speech rate. Length of CAG repeats, Unified Huntington’s Disease Rating Scale total motor score, and percent intelligibility were significantly different for pairwise comparisons of subgroups. Conclusion This study supports the existence of distinct presentations of dysarthria in patients with HD, which may be due to divergent pathologic processes. The findings are discussed in relation to previous literature and clinical implications.

TL;DR: Patients with SS have voice, speech and swallowing abnormalities, not only associated to xerosis but perhaps also to neurological abnormalities, probably secondary to the syndrome.
Abstract: Objective: To identify and describe voice, speech and swallowing abnormalities in patients with Sjogren’s syndrome (SS). Materials and methods: This was a prospective cross-sectional descriptive observational study. Patients with SS were interviewed and physically explored. Nasolaryngeal endoscopy, video laryngeal stroboscopy, fiberoptic endoscopic evaluation of swallowing and computerized voice spectrographic analysis (PRAAT ® software) of voice and speech were also performed. Results: We included 31 patients (96.7% women). Average time of evolution was 5 years; mean age was 48.4 years. Of these SS cases, 87% were secondary and 13% primary. Symptomatology: 70.9% dysphagia, 41.9% dysphonia, 35.4% dysglossia, 3.2% dysarthria. We found abnormalities principally in: one or more cranial nerves (V, VII, IX, X, XII) (67.7%), nasopharyngolaryngeal mucosa (77.4%), mucosal wave of vocal cords (90%), swallowing mechanism (90.3%), spectrogram of the vowels /e/ (58.06%) and /i/ (51.61%), and rhythm of the trisyllable ‘‘pataka’’ (35.48%). Conclusions: Patients with SS have voice, speech and swallowing abnormalities, not only associated to xerosis but perhaps also to neurological abnormalities, probably secondary to the syndrome.

TL;DR: This is the first study to compare the effects of medical and STN-DBS treatment on speech and limb movement in PD over a year and the different effects of STN -DBS and medication on Speech and limb movements warrant further investigation.
Abstract: Impairment of speech can affect the majority of patients with Parkinson's disease (PD). Deep brain stimulation of the subthalamic nucleus (STN-DBS) is an effective treatment for the improvement of limb movements, but its effect on speech is less predictable. This study aims to compare the effects of STN-DBS versus the effects of medical (drug) treatment alone on speech and limb movement over 1 year. Sixteen consecutive patients with PD, who were part of a larger trial, were randomized in two groups, either surgical treatment (N = 8) with bilateral STN-DBS or medical treatment (N = 8). Both groups were assessed in the "on and off" medication states, at baseline and at 1 year, using a speech evaluation protocol and the motor part of the Unified Parkinson's Disease Rating Scale (UPDRS-III). The group that received STN-DBS was also assessed in the "on and off" stimulation states. The speech evaluation consisted of recordings of sustained phonation, sentence reading, and 1 minute of monologue. The STN-DBS group in the "on medication and on stimulation" state showed an improvement of the UPDRS-III score. Stimulation and medication also increased significantly the intensity of sustained phonation and the mean of long-term average spectra of the read sentences and the monologue. The sentence intelligibility scores did not change significantly in either group, with the STN-DBS patients showing a wide variability. All acoustical measures of speech for the medical group showed a small and nonsignificant deterioration over 1 year. This is the first study to compare the effects of medical and STN-DBS treatment on speech and limb movement in PD over a year. The different effects of STN-DBS and medication on speech and limb movement warrant further investigation.
