Clinical experience of speech and language therapists working in Sri Lanka has put into question the current reliance on norms for English (Grunwell, 1985) to determine a child’s speech skills and phonological acquisition in Sinhala. Cross-linguistic studies have revealed differences in ‘universal principles’ and ‘language-specific’ aspects (Amayreh & Dyson, 1998). At present, there is an urgent need to develop and validate formal language-specific standardized assessments for speech and phonology for Sinhala. The aims of the study were; 1)to develop and validate test items for a Sinhala speech and phonology assessment for children aged between 3;0 to 6;0 years, 2)to document the typical phoneme acquisition and typical phonological processes in Sinhala-speaking children aged between 3;0 to 6;0 years. The ‘Sinhala Speech and Phonology Assessment’ was devised based on the Diagnostic Evaluation of Articulation and Phonology (Dodd et al. 2002) and administered to 250 Sinhala-speaking children between the ages 3;0 to 6;00 years. The use of test items were determined by measures of content validity, test-retest reliability and inter-rater reliability. The trajectory of Sinhala speech sound acquisition showed universal sound acquisition sequences and language-specific features in both the order and rate of speech sound development. The sequence of speech sound acquisition for Sinhala showed early acquisition of plosives and some nasals with comparatively later acquisition of fricatives, the palatal nasal and flap/tap sound. Language-specific phonological processes of lateralization and denasalisation of prenasalised stops were also evident. The test items demonstrated effectiveness at generating target speech data and typical phoneme and phonological development in children between 3;0 to 6;0.
Enabling access: A pilot study on access and use of assistive products in the Northern Province, Sri Lanka
(VU e-Publishing, Netherlands, 2019) Hettiarachchi, S.; Subramaniam, V.; Rajah, E.; Nizar, S.; Saleem, S.
PURPOSE: The need for suitable assistive technology is growing all over the world, not only for people with disabilities but also for the ageing population with functional decline and non-communicable diseases. Access to assistive technology promotes access to education, employment and active societal participation. The aim of this study was to assess the self-reported need by persons with disabilities and by people who were 65 years and older without disabilities in the Northern Province of Sri Lanka, for assistive products; and to identify barriers to accessing these assistive products. METHOD: This mixed-methods pilot study included 76 participants who were either persons with disabilities or their caregiver or persons 65 years and older, from the Northern Province of Sri Lanka, affected by the now-ended 30-year civil war. To ascertain trends in the local need for assistive products, a translated version of the World Health Organisation's Priority Assistive Products List of 50 items was used. In addition, semi-structured interviews with key participants were conducted, to gain some insights into the barriers to accessing assistive products. RESULTS: The most widely used assistive products among persons with disabilities were connected to war-related injuries. In contrast, those used by the older age group of persons without disabilities were connected to non-communicable diseases and age-related frailty. The assistive products requested by both groups were aids to promote independence in daily activities and to support access to education and employment. The emergent themes included affordability, employment, independence in activities of daily living, stigma and psychological impact, and a lack of awareness and guidance in the use of assistive devices. CONCLUSION: The findings highlight the need for policies and practices to be informed by local socio-cultural, historical and geographical realities.

Investigating Parkinson's disease with dual high resolution pharyngeal manometry with impedance and videofluoroscopy
(Blackwell Publishing, 2024) Saleem, S.; Miles, A.; Allen, J.
PURPOSE: To characterize pharyngeal function in people with Parkinson's Disease using both high resolution impedance manometry (HRIM) and videofluoroscopy (VFSS) and to explore correlations between VFSS and HRIM metrics. METHODS: All participants received both VFSS and HRIM within 24 h-time window. A standard VFSS protocol (IDDSI 0: 1 mL, 3 mL, 20 mL, and 100 mL) was performed. A solid-state unidirectional catheter (36 pressure sensors) was used to acquire manometric data for triplicate swallows (IDDSI 0: 5 mL, 10 mL, 20 mL), quantitative swallow analysis was completed through Swallowtail™ and SwallowGateway™. Parameters were compared to published norms and statistical tests explored correlational associations (p < 0.05). RESULTS: Twenty-one participants (76% male; mean age 70 years, SD7.16) with mild-moderate severity PD were recruited with 73% reporting Eating Assessment Tool (EAT-10) scores ≥3 indicating swallow impairment. Compared to normal metrics, one third of participants had abnormally elevated hypopharyngeal contractile integral (HPCI), hypopharyngeal peak pressure, upper esophageal sphincter (UES) integrated relaxation pressure (UES IRP), and reduced UES maximum admittance. Five participants showed compromised swallow safety (Penetration-Aspiration Scale score ≥6). One third of participants had abnormal VFSS values for pharyngoesophageal segment (PES) opening duration, maximum PES opening distance, and maximum hyoid displacement measures. Some HRIM metrics had a strong correlation with pharyngeal VFSS measures (r > 0.60, p < 0.05). CONCLUSION: This study identifies early manometric signs of pharyngeal dysfunction in people with PD. The congruence of the VFSS and HRIM measures confirms the hypothesis of insidious early decline in swallow function in PD despite maintenance of airway safety (i.e., low aspiration rates).

A systematic review of behavioural therapies for improving swallow and cough function in Parkinson's disease
(Taylor and Francis Group, 2024) Saleem, S.; Miles, A.; Allen, J.
Purpose: This systematic review evaluated the efficacy of therapeutic interventions on improving swallow, respiratory, and cough functions in Parkinson's disease (PD).Method: A PRISMA systematic search was implemented across six databases. We selected studies reporting pre- and post-assessment data on the efficacy of behavioural therapies with a swallow or respiratory/cough outcome, and excluded studies on medical/surgical treatments or single-session design. Cross-system outcomes across swallow, respiratory, and cough functions were explored. Cochrane's risk of bias tools were utilised to evaluate study quality.Result: Thirty-six articles were identified and further clustered into four treatment types: swallow related (n = 5), electromagnetic stimulation (n = 4), respiratory loading (n = 20), and voice loading (n = 7) therapies. The effects of some behavioural therapies were supported with high-quality evidence in improving specific swallow efficiency, respiratory pressure/volume, and cough measures. Only eleven studies were rated with a low risk of bias and the remaining studies failed to adequately describe blinding of assessors, missing data, treatment adherence, and imbalance assignment to groups.Conclusion: Behavioural therapies were diverse in nature and many treatments demonstrated broad cross-system outcome benefits across swallow, respiratory, and cough functions. Given the progressive nature of the condition, the focus of future trials should be evaluating follow-up therapy effects and larger patient populations, including those with more severe disease.

Typical phonemic and phonological development of three year old Sri Lankan Tamil – speaking children in the Colombo district
(University of Kelaniya, 2013) Saleem, S.; Hettiarachchi, S.
Background: In Sri Lanka, speech and language therapists currently use standardized English language norms in clinical practice for diagnosis and when planning intervention for speech disorders. Cross - linguistic studies have shown that languages have both universal and specific features; the norms of one language can thus not be applied to another. So, the need to obtain language specific normative data of speech development for children in Sri Lanka is essential for assessment and differential diagnoses. Objectives: The objective of this study is to determine the speech sound inventory and phonological error patterns that exist in Sri Lankan Tamil speaking 3 year old children. In addition, it also investigates the effect of age, gender and socio dialectal variation on speech sound development. Materials and methods: An informal picture-based assessment was used to gain speech samples from 80 Tamil-speaking children between the ages of 3;0 – 3;11 years from Colombo district. The data were phonetically transcribed and audio recorded. In addition, the data were statistically analysed using t-tests and qualitatively analysed with reference to norms for English used in current clinical practice. Results: It was found that 75% of speech sounds are acquired by the age of 4;0. The children produced more speech sounds at an earlier age than their English- speaking peers. The findings indicate a statistically significant influence of age on phoneme acquisition and on the suppression of phonological error patterns, but no significant effect was found on gender or socio- dialectical variation. Conclusions and recommendations: The findings can be used as tentative norms in clinical practice for Sri Lankan Tamil speaking children. Furthermore, the study can provide speech-language therapists with a framework for further research, and contribute to constructing a relevant database for Sri Lankan Tamil speech development.
Views of Teachers, Caregivers and Children with Cerebral Palsy on the Understanding and Use of Augmentative and Alternative Communication Systems in Sri Lanka
(Faculty of Medicine, University of Kelaniya, 2014) Saleem, S.; Bandara, M.M.M.K.; Subajini, A.A.N.; Udugama, K.L.L.G.; Dharmaratne, I.; Kitnasamy, G.; Hettiarachchi, S.
Every child’s and adult’s right to communicate is a basic human right, promoted by the Disability Rights Movement. However, the use of Augmentative and Alternative Communication (AAC) modes remains ambiguous, possibly dependent on socio-cultural and economic factors influencing the understanding of and access to AAC devices. The findings from a UK-based project (2013) stressed the need to provide AAC training and learning provision to all stakeholders. The aim of this study was to uncover the current understanding of and use of AAC among 30 teachers, 30 caregivers and 10 children with cerebral palsy. Qualitative and quantitative data were gathered via a survey and open-ended interviews with the AAC users encouraged to use available communication devices and artwork. Although a majority of special education teachers had heard of AAC systems, mainly of Bliss symbols, in contrast to Mainstream teachers, overall, there was a propensity towards favoring oral communication. There was a limited understanding of the concept of AAC and a persons’ right to use alternative and augmentative communication modes by a majority of teachers and caregivers. The use of AAC systems is very limited, based on the awareness and access to a speech therapist and if used, mainly limited to the speech therapy sessions in the school. The child participants favored the BigMac switches and the attention-seeking bells on low-tech AAC devices where available. While the younger children used the communication charts during speech therapy sessions, the older children were less enthusiastic about using low-tech communication boards and books.
When No Speech Norms Exist: Observations From Sinhala
(American Speech-Language-Hearing Association, 2024-11) Hettiarachchi, S.; Ranaweera, M.; Saleem, S.; Krishnaveni, K.
PURPOSE A well-established set of language-specific norms for phonological development is imperative in the assessment of child speech sound difficulties. Currently, English norms are used clinically (in the absence of norms for local languages) to determine if a child displays age-appropriate, delayed or disordered speech patterns in Sinhala. This preliminary exploratory study aimed to document phonological processes observed in typically developing Sinhala-speaking children aged 3;0-6;11 (years;months).METHOD The Test of Articulation and Phonology-Sinhala, a picture-based assessment, was devised by the researchers and administered to 102 Sinhala-speaking children from three geographical locations (Colombo, Kandy, and Gampaha). The quantitative measures included percent consonants correct, percent vowels correct, and percent phonemes correct, while the qualitative analysis identified phonological processes.RESULTS The quantitative results showed a marked influence of age on phoneme production accuracy with over 75% consonants correct by 3 years 6 months. The qualitative findings demonstrate common typical phonological processes and less common phonological processes in Sinhala compared to the speech pathology and cross-linguistic literature. Common phonological processes included fronting, stopping, and weak syllable deletion widely documented in linguistic and speech-language pathology literature. Many shared phonological processes were observed between Sinhala and Sri Lankan Tamil, the two main local languages, including fronting of retroflex sounds and lateralization. The phonological process of denasalization of prenasalized stops was observed in Sinhala, with no documentation of the phonological process found within the mainstream speech-language pathology literature.CONCLUSION AND IMPLICATIONS: These findings reinforce the need to document and use language-specific typical phonological processes in Sinhala given the implications for early and accurate identification of speech difficulties and intervention.
