The speech intelligibility and articulatory impairment of 32 spastic and 18 athetoid males, aged 17–55, were examined. Selection was based on a definite diagnosis of cerebral palsy, and adequate intelligence, hearing, and ability to perform the required tasks. Two estimates of speech intelligibility were obtained from naive listeners: single words correctly recognized and prose intelligibility rating. Diadochokinetic (DDK) syllable rates and percent correct articulation of selected phonemes were employed as indices of articulatory impairment. The 50 subjects were, on average, judged to be 50% intelligible on both intelligibility estimates. Group mean DDK rate was 2.9 syllables per second and 78% of phonemes were transcribed as correctly articulated. The mean scores of the spastic subjects were superior to the athetoids on all speech measures, significantly so for single-word intelligibility and DDK rate even when group inequalities for physical disability and I.Q. were adjusted. In this sample, spastics were less physically disabled and had lower I.Q.'s than athetoids. Specific phonemic features characteristic of the dysarthria in cerebral-palsied subjects were: (1) anterior lingual place inaccuracy; (2) reduced precision of fricative and affricate manners; and (3) inability to achieve the extreme positions in the vowel articulatory space. A comparison of these results with those reported for children with cerebraI palsy suggests that the consonantal place and manner problems are fairly stable features of cerebral palsy dysarthria.

The articulation errors of 32 spastic and 18 athetoid males, aged 17–55 years, were analyzed using a confusion matrix paradigm. The subjects had a diagnosis of congenital cerebral palsy, and adequate intelligence, hearing, and ability to perform the speech task. Phonetic transcriptions were made of single-word utterances which contained 49 selected phonemes: 22 word-initial consonants, 18 word-final consonants and nine vowels. Errors of substitution, omission and distortion were categorized on confusion matrices such that patterns could be observed. It was found that within-manner errors (place or voicing errors or both) exceeded between-manner errors by a substantial amount, more so on final consonants. The predominant within-manner errors occurred on fricative phonemes for both initial and final positions. Affricate within-manner errors, all of devoicing, were also frequent in final position. The predominant between-manner initial position errors involved liquid-to-glide and affricate-to-stop changes, and for final position, affricate-to-fricative. Phoneme omission occurred three times more frequently on final than on initial consonants. The error data of individual subjects were found to correspond with the identified overall group patterns. Those with markedly reduced speech intelligibility demonstrated the same patterns of error as the overall group. The implications for treatment are discussed.

Neurological disorders are among the major causes of physical disability in children. The aim of this study was to investigate the prevalence and pattern of Paediatric Neurological Disorders (PNDs) managed in outpatient Physiotherapy clinics in Kano. The 10-year retrospective descriptive study collected relevant data on PNDs from case files of the children who have been managed in Physiotherapy clinics of the 5 major referral hospitals in Kano using a data capture form. The population of children in Kano State based on the 2006 Census and the projected population for 2017 was obtained from the National Population Commission, Kano State office. The data obtained was analysed with descriptive statistics of mean, standard deviation, frequency and percentage. Dataanalysis was done using Microsoft excel and SPSS version 20. Results showed that 1927paediatric cases were analysed out of which PNDs accounted for 1618 (83.96%). The mean age of the children at the time of their first treatment visit was 3.13 years ± 3.04years (range =33days-12years). Most of the children with PNDs are males 1101(57.1%), with male to female ratio of 1.3:1. The Prevalence of PNDs in Kano was 0.257/1000 (i.e.25.7/100,000). The most common PND that was managed by physiotherapists in KanoState was cerebral palsy which has a prevalence of 0.106/1000 (i.e.10.6/100,000),(proportion = 41.16%). It was concluded that PNDs are the most common paediatric cases managed by physiotherapists in Kano State with cerebral palsy having higherprevalence

Abstract The purpose of this opinion article is to review the impact of the principles and technology of speech science on clinical practice in the area of craniofacial disorders. Current practice relative to (a) speech aerodynamic assessment, (b) computer-assisted single-word speech intelligibility testing, and (c) behavioral management of hypernasal resonance are reviewed. Future directions and/or refinement of each area are also identified. It is suggested that both challenging and rewarding times are in store for clinical researchers in craniofacial disorders.

Purpose A single-word identification test was used to study speech production in children and adults with Down syndrome (DS) to determine the developmental pattern of speech intelligibility with an emphasis on vowels. Method Speech recordings were collected from 62 participants with DS aged 4–40 years and 25 typically developing participants aged 4–7 years. Panels of 5 adult lay listeners transcribed the speech recordings orthographically, and their responses were scored in comparison with the speakers' target words. Results Speech intelligibility in persons with DS improved with age, especially between the ages of 4 and 16 years. Whereas consonants contribute to intelligibility, vowels also played an important role in reduced intelligibility with an apparent developmental difference in low versus high vowels, where the vowels /æ/ and/ɑ/ developed at a later age than /i/ and /u/. Interspeaker variability was large, with male individuals being generally less intelligible than female individuals and some adult men having very low intelligibility. Conclusion Results show age-related patterns in speech intelligibility in persons with DS and identify the contribution of dimensions of vowel production to intelligibility. The methods used clarify the phonetic basis of reduced intelligibility, with implications for assessment and treatment.

Abstract Background This study assessed the safety and efficacy of intrathecal injection of umbilical cord tissue mesenchymal stem cells (UCT-MSC) in individuals with cerebral palsy (CP). The diffusion tensor imaging (DTI) was performed to evaluate the alterations in white-matter integrity. Methods Participants (4–14 years old) with spastic CP were assigned in 1:1 ratio to receive either UCT-MSC or sham procedure. Single-dose (2 × 107) cells were administered in the experimental group. Small needle pricks to the lower back were performed in the sham-control arm. All individuals were sedated to prevent awareness. The primary endpoints were the mean changes in gross motor function measure (GMFM)-66 from baseline to 12 months after procedures. The mean changes in the modified Ashworth scale (MAS), pediatric evaluation of disability inventory (PEDI), and CP quality of life (CP-QoL) were also assessed. Secondary endpoints were the mean changes in fractional anisotropy (FA) and mean diffusivity (MD) of corticospinal tract (CST) and posterior thalamic radiation (PTR). Results There were 36 participants in each group. The mean GMFM-66 scores after 12 months of intervention were significantly higher in the UCT-MSC group compared to baseline (10.65; 95%CI 5.39, 15.91) and control (β 8.07; 95%CI 1.62, 14.52; Cohen’s d 0.92). The increase was also seen in total PEDI scores (vs baseline 8.53; 95%CI 4.98, 12.08; vs control: β 6.87; 95%CI 1.52, 12.21; Cohen’s d 0.70). The mean change in MAS scores after 12 months of cell injection reduced compared to baseline (−1.0; 95%CI −1.31, −0.69) and control (β −0.72; 95%CI −1.18, −0.26; Cohen’s d 0.76). Regarding CP-QoL, mean changes in domains including friends and family, participation in activities, and communication were higher than the control group with a large effect size. The DTI analysis in the experimental group showed that mean FA increased (CST 0.032; 95%CI 0.02, 0.03. PTR 0.024; 95%CI 0.020, 0.028) and MD decreased (CST −0.035 × 10-3; 95%CI −0.04 × 10-3, −0.02 × 10-3. PTR −0.045 × 10-3; 95%CI −0.05 × 10-3, −0.03 × 10-3); compared to baseline. The mean changes were significantly higher than the control group. Conclusions The UCT-MSC transplantation was safe and may improve the clinical and imaging outcomes. Trial registration The study was registered with ClinicalTrials.gov (NCT03795974).

This study examined the frequency of occurrence of velar deviations in spontaneous single-word utterances over a 6-month period for 40 children who ranged in age from 1:11 (years:months) to 3:1 at the first observation. The productions of a subset of 14 children whose percentage of occurrence of velar deviations was greater than the mean of the total group were examined further to describe the types of velar deviations and the effects of word position and phonetic context. Results indicated that velars presented difficulty for less than half of the children. In the subgroup the type of deviation and the percentage of correct velars appeared to vary with the position in the word, the vowel environment, and the velar's function as a singleton or as one segment of a cluster.
