RESUMEN

Background: In South Africa, the sharp rise in people with severe illness because of coronavirus disease 2019 (COVID-19) in early 2020, meant that health systems needed to adapt services and operations, including rehabilitation services. Important insights into the lived experiences of rehabilitation personnel enacting these adaptations in an African context are limited. Objectives: The aim of this study was to explore the lived experiences of rehabilitation practitioners working in the public sector in South Africa during the COVID-19 pandemic. Method: A phenomenological approach and a duo-ethnographic design were used. A recruitment letter was circulated requesting volunteers. Maximum variation sampling was used to select the 12 participants of this study. Data were collected through interviews via Zoom, and critical conversations were facilitated by a non-rehabilitation partner who is known for challenging health inequities. The interviews were audio-recorded and transcribed verbatim. Data were analysed through elements of qualitative content and thematic analysis. Data were coded, categorised, clustered into concepts and formulated into themes. Results: Three themes were identified: (1) 'Management became the enemy', (2) 'Tired of being resilient' and (3) 'Think out of the box…think on our feet'. Conclusion: The results of this study highlighted new ways of practice, innovative adaptations, and usage of resources and platforms. Contribution: This study highlights the re-imagining of accessible rehabilitation services that could lead to deeper onto-epistemological shifts amongst the rehabilitation practitioners.

RESUMEN

INTRODUCTION: Bilinguals constitute a significant portion of speech-language pathologists' (SLPs) caseloads. Insight into the cross-linguistic effect on voice is needed to guide SLPs to make linguistically appropriate observations when working with heterogenous populations. METHOD: Nineteen female English-Northern Sotho bilinguals performed three speech tasks (reading, picture description, and monologue) in each language. Acoustic analysis of mean fundamental frequency (f0), intensity, and articulation rate was conducted with Praat. A panel of blinded listeners reached consensus after independently reviewing the recordings during perceptual analysis of voice quality, resonance, and glottal attack. RESULTS: The following statistically significant differences were found across and within the languages: The mean f0 was 204.61 Hz in the Northern Sotho picture description yet 196.50 Hz in the English picture description. The mean intensity of reading in Northern Sotho was 66.38 dB whereas the mean intensity of reading in English was 65.09 dB. Articulation rate was 3.78 syllables/s in English passage reading and 3.41 syllables/s in Northern Sotho passage reading. Within English, passage reading elicited a significantly quicker articulation rate than the picture description (3.34 syllables/s) and monologue (3.46 syllables/s). Within Northern Sotho, mean f0 was 203.83 Hz in passage reading yet 191.11 Hz in the monologue. Perceptual voice quality, glottal attack, and resonance were comparable across languages. CONCLUSION: Relationships between languages spoken, task performance, and vocal characteristics were observed in English-Northern Sotho bilingual females. SLPs must consider the interaction of language, task performance, and vocal characteristics when working with bilingual clients.

RESUMEN

The purpose of the study was to describe the evolution of outcomes among full-term infants with moderate hypoxic-ischemic encephalopathy (HIE); from their early swallowing and feeding abilities during hospitalization, to their later developmental outcomes at 6 and 12 months. Four participants with moderate HIE were recruited. Early feeding and swallowing were assessed using the Neonatal Feeding Assessment Scale and video fluoroscopic swallow studies. Developmental assessments were conducted at 6 and 12 months using the Rossetti Infant-Toddler Language Scale and Vineland-3 Scale. All participants displayed atypical outcomes throughout the study, including oropharyngeal dysphagia initially during hospitalization. All participants were discharged on oral feeds but some breastfeeding difficulties persisted. Variable but pervasive developmental delays were found among all participants at 6 and 12 months. This study emphasizes the need for consistent early intervention from the neonatal period onward, for all infants with moderate HIE. Future studies should use larger cohorts, longer follow-up, and correlational designs.

RESUMEN

Adequate early childhood development is critical for later-life success. Developmental profiles of specific populations are required to support implementation of early intervention services. Three hundred fifty-three caregivers of children with mean age 17.9 months (SD = 10.5) were selected from a primary healthcare clinic. Overall positive identification of signs of a developmental delay, with the Bayley Scales of Infant and Toddler Development III, was 51.8% (n = 183). Logistic regression analysis determined the effect of age and gender on results. Prevalence of developmental delay increased with age from 33.1% for children under 12 months to 61.7% and 66.3% for children between 13-24 months and 25-36 months, respectively. Females were 1.82 times (95% CI [1.16, 2.85]) more likely to have had no signs of developmental delay; 2.30 times (95% CI [1.14, 4.65]) in motor and 2.06 times (95% CI [1.23, 3.45]) in adaptive behaviour domains. One-third of children presented with low levels of adaptive behaviour functioning. One hundred and one (28.6%) participants across age groups displayed superior social-emotional ability, possibly due to familial structures and relationships. One-third of children presented with poor adaptive behaviour function, attributed to cultural differences. This study contributes to information on developmental characteristics of children in South Africa.

RESUMEN

PURPOSE: Language sample analysis is widely regarded as the gold standard of language assessment. However, the uncertainty regarding the optimal length of sample and the limited availability of developmental language data for nonmainstream languages such as Afrikaans complicate reliable use of the method. The study aimed to provide guidelines on representative length of sample and concurrently provide a preliminary description of the spoken language skills of Afrikaans-speaking children. METHOD: The study involved 30 typically developing Afrikaans-speaking children aged between 3;6 and 9;6 (years;months). A descriptive research design was used to transcribe and analyze 1-hr interactions collected in natural environments of participants who were recruited using referral sampling. Video and audio recordings of the samples were transcribed using adapted Sampling Utterances and Grammatical Analysis Revised analysis procedures. RESULTS: Results indicated that mean length of utterance in words per minute, number of different words per minute, and total number of words per minute stabilized at 30 min and no significant differences were found between 30 min and longer time segments. Morphology results concur with existing developmental findings in Afrikaans. Lexical diversity results correlated with the findings of the lexical specificity and accuracy in the Prutting and Kirchner Pragmatic Protocol (Prutting & Kirchner, 1987). The developmental trajectories for pragmatic and phonological development were consistent with existing guidelines. CONCLUSIONS: The study concluded that a 30-min interaction segment provides a representative language sample for Afrikaans-speaking children who are between 3;6 and 9;6. It provides promising preliminary developmental data and clinical guidelines, confirming the potential of language sample analysis (LSA) as a reliable component of language assessment in Afrikaans.

RESUMEN

OBJECTIVES: The study aimed to describe daily vocal demands, perceptions and knowledge as reported by occupational voice users. STUDY DESIGN: A descriptive, cross-sectional research design was employed. METHODS: A survey on vocal demands, perceptions and knowledge was distributed to 102 occupational voice users via a snowball sampling technique. RESULTS: Slightly more than half of the participants (55%) reported using their voice for work 36.5 hours a week on average (SD = 15.5, range: 33-40). Participants reported that, on average, their daily voice use is 6.3 hours (SD = 2.7) for work and the majority (81%) reported a decrease in voice quality after work; Three-quarters (75%) also reported vocal fatigue at the end of day. Approximately one-third (33%) reported being exposed to environments where they are expected to shout, scream or cheer loudly. More than half of the participants (61%) reported that they have previously received vocal health education but 40% reported that they felt this training was insufficient. High vocal demands are significantly correlated to an increase in perceived vocal handicap rs = 0.242; (P = 0.018), tiredness of voice rs = 0.270; (P = 0.008), physical discomfort rs = 0.217; (P = 0.038) as well as how occupational voice users experience improvement of symptoms with rest rs = -0.356 (P < 0.001). Other risk factors highlighted by occupational voice users are the ingestion of liquid caffeine, alcohol, and carbonated drinks, smoking or the presence of chronic cough, chronic laryngitis, and gastroesophageal reflux disease. CONCLUSIONS: Occupational voice users are subjected to high daily vocal demands that can be seen to be linked to vocal fatigue, changes in voice quality and vocal symptoms experienced. It is essential that occupational voice users as well as treating clinicians are aware of certain significant predictors of both vocal handicap and vocal fatigue. These findings provide insights for developing strategies for training and cultivating vocal health consciousness and preventive voice care initiatives that focus on occupational voice users in South Africa.

RESUMEN

INTRODUCTION: Culturally relevant developmental screening is one of the best ways to appropriately identify developmental delays and disabilities in children as early as possible across diverse cultural backgrounds. This study aimed to adapt the Parents' Evaluation of Developmental Status (PEDS) tools for a low-income community in South Africa by using a detailed multiphased cultural and contextual adaption process. METHOD AND RESULTS: A three-phase mixed-method design relying on triangulation of data was used. Data were collected at an immunization clinic in a low-income community in Mamelodi, South Africa. Phase 1 was a focus group discussion with 11 community participants. The topics explored the possible changes to the PEDS tools to make them more relevant to the community. Phase 1 informed Phase 2 where 12 early childhood development experts achieved consensus through a two-round survey on a modified Delphi method. In Phase 3, a draft of the PEDS tools-SA was presented to the authors of the PEDS tools for final approval. Of 55 questions that were adapted for the PEDS tools-SA, two original questions (3.6%), 14 questions from the expert suggestions (25.4%) and 39 from the community participant's suggestions (71%) were included. A final version of the PEDS tools-SA was created. CONCLUSION: This study used a systematic method to adapt the PEDS tools to create the culturally appropriate PEDS tool-SA for a low-income community in South Africa, informed by community stakeholders' views from the first step. This resulted in a high-quality adaptation process that is more likely to result in a tool that is more acceptable to caregivers from a low-income South African community.

RESUMEN

BACKGROUND: Language sample analysis (LSA) is invaluable to describe and understand child language use and development for clinical purposes and research. Digital tools supporting LSA are available, but many of the LSA steps have not been automated. Nevertheless, programs that include automatic speech recognition (ASR), the first step of LSA, have already reached mainstream applicability. SUMMARY: To better understand the complexity, challenges, and future needs of automatic LSA from a technological perspective, including the tasks of transcribing, annotating, and analysing natural child language samples, this article takes on a multidisciplinary view. Requirements of a fully automated LSA process are characterized, features of existing LSA software tools compared, and prior work from the disciplines of information science and computational linguistics reviewed. KEY MESSAGES: Existing tools vary in their extent of automation provided across the process of LSA. Advances in machine learning for speech recognition and processing have potential to facilitate LSA, but the specifics of child speech and language as well as the lack of child data complicate software design. A transdisciplinary approach is recommended as feasible to support future software development for LSA.

RESUMEN

BACKGROUND:  Studies related to tube feeding in people with dementia (PWD) remain a contested topic, neglecting the importance of speech-language therapists' (SLTs) role in dysphagia management. Furthermore, SLT practices and beliefs regarding tube feeding in people with advanced dementia in an upper-middle-income country, such as South Africa, are unexplored. OBJECTIVE:  This study aimed to determine the practices and beliefs of SLTs in South Africa regarding tube feeding placement in PWD. METHOD:  A self-compiled online survey was distributed using social media platforms and was completed by 83 South African SLTs with experience in swallowing and feeding management of PWD. RESULTS:  Most SLTs (78.8%) strongly believed they play a vital role in the decision-making regarding feeding tube insertion in PWD. This role is often met with several challenges, such as limited support from other healthcare professionals. Speech-language therapists with more experience and increased involvement in palliative care appeared to be more confident in supporting and counselling families of PWD on tube feeding. Many SLTs still recommend tube feeding despite its known negative consequences for PWD. CONCLUSION:  The findings indicate a need for continued professional development for South African SLTs on feeding decisions in advanced dementia to increase knowledge and confidence in clinical practice. Speech-language therapists require guidelines by professional bodies and further dialogue amongst healthcare professionals to guide difficult feeding decisions in people with advanced dementia.

RESUMEN

PURPOSE: This study aimed to critically appraise recent peer-reviewed scientific evidence on the effect of vocal hygiene education on voice quality and function directly and indirectly measured by auditory-perceptual, acoustic, and self-report measures in professional voice users. METHOD: A systematic review was conducted utilizing the Preferred Reporting Items for Systematic review and Meta-Analyses Protocols (PRISMA-P) guidelines. Five databases were searched using the keywords "vocal hygiene," "vocal hygiene education," "vocal health," "vocal quality," and "voice quality" with Boolean phrases "AND" and "OR." Twenty-three studies that met the eligibility criteria were included. Scoring was based on the American Speech-Language-Hearing Association's levels of evidence and quality indicators, as well as the Newcastle-Ottawa Scale for assessing the risk of bias. RESULTS: Four studies (17%) linked low awareness of vocal hygiene or insufficient vocal hygiene education to self-reported acute and chronic voice symptoms, as well as a greater perception of voice handicap among professional voice users. Numerous studies (n = 10; 43%) showed that adequate voice training or vocal hygiene education was linked to positive voice outcomes. Six studies (6.26%), however, demonstrated that vocal hygiene education is more effective when combined with direct voice therapy. When vocal hygiene education is presented in isolation, the superiority of a direct voice therapy approach, with or without vocal hygiene education, is seen over a vocal hygiene education program alone (indirect treatment). CONCLUSIONS: Recent literature demonstrates mixed results obtained through auditory-perceptual, acoustic, and self-rating measures on the effects of vocal hygiene instruction on vocal quality and function in professional voice users. However, the compelling positive outcomes presented do warrant implementation of vocal hygiene education programs in combination with direct voice therapy for professional voice users.

RESUMEN

BACKGROUND:  Laryngopharyngeal reflux (LPR) is prevalent and can lead to voice disorders, but its diagnosis is difficult, because of limited correlations between clinical symptoms and organic pathology. Various tools and methods have been explored to aid a diagnosis of LPR. OBJECTIVE:  To investigate associations between reflux symptoms, acoustic-, perceptual-, and physical vocal characteristics, glottal function index (GFI), and vocal handicap index (VHI) in adults with non-organic voice disorders. METHODS:  Data of 51 adults with non-organic voice disorders were collected, using a retrospective cohort explorative research design, at a private ear, nose and throat specialist practice in Gauteng, South Africa. Quantitative outcomes were compared between reflux symptom index (RSI), acoustic characteristics (jitter, shimmer and fundamental frequency [F0]), maximum phonation time, perceptual- (GRBASI) and physical vocal characteristics, GFI and VHI. RESULTS:  The RSI showed positive fair correlations against GFI, VHIP and caffeine intake, indicating an increase in reflux symptoms with higher scores on the various measures. Moderate correlations were also found between GFI and VHIP, grade of hoarseness and jitter, strain and VHIP, strain and VHI total (VHIT) and between Asthenia and jitter. Very strong correlations were found within the various subsections of the VHI as well as between jitter and shimmer and between F0-male and physical symptoms of the VHI (VHIP). CONCLUSION:  Results indicated associations between reflux symptoms, vocal characteristics, the GFI and the VHI. Based on the correlations found these tools used in conjunction could improve clinical diagnosis of LPR. Implications of these findings are promising, but further research is recommended.Contribution: This study contributes to the body of knowledge to support the accurate clinical diagnosis of LPR using subjective measures to determine LPR symptoms, as well as acoustic analysis.

RESUMEN

(1) Hearing health training and promotion is a priority for early childhood development (ECD) practitioners, but training opportunities are limited, especially in low- and middle-income countries (LMIC). mHealth (mobile health) has the potential to deliver scalable ear and hearing training to ECD practitioners. (2) This study investigated the effect of an mHealth training intervention program for ECD practitioners to improve knowledge and perceptions of hearing health in young children. An experimental one-group, pre-post-test study included ECD practitioners working with children between birth and 6 years old across 31 neighbouring communities in the Western Cape Province, South Africa. Hearing health training was provided using WhatsApp messages that encompassed infographics and voice notes. Knowledge and perceptions regarding hearing and hearing-related problems in children were surveyed pre-training, directly post training, and 6 months post training. (3) ECD practitioners (N = 1012) between 17 and 71 years of age received the mHealth training program and completed both the pre-and post-training surveys. Overall, knowledge scores indicated a significant improvement from pre- to post training (Z = -22.49; p < 0.001). Six-month post-training knowledge scores were sustained. Content analysis of ECD practitioners' application of the training information 6 months post training indicated improved awareness, practical application, better assistance for hearing problems, and widespread advocacy. (4) The mHealth training program supports improved knowledge and perceptions of ECD practitioners regarding hearing health for young children. With improved knowledge scores maintained 6 months post training, mHealth hearing health training is an effective intervention. An mHealth training program for ECD practitioners provides a scalable, low-cost intervention for primary and secondary prevention in childhood hearing loss, especially in LMICs.

RESUMEN

PURPOSE: To describe the evolution of swallowing and feeding abilities of neonates with hypoxic-ischaemic encephalopathy (HIE) during hospitalisation. METHOD: A longitudinal cohort study was used. Twenty-nine participants (median age 39.0 weeks [IQR = 2.0 weeks]) with mild (n = 7), moderate (n = 19) and severe (n = 3) HIE were included. Clinical swallowing and feeding assessments were conducted at introduction of oral feeds and at discharge using the Neonatal Feeding Assessment Scale (NFAS). Videofluoroscopic swallow studies (VFSS) supplemented the NFAS before discharge. RESULT: Approximately two thirds of participants showed symptoms of oropharyngeal dysphagia (OPD) during initial NFAS and VFSS. Significantly fewer OPD symptoms occurred at discharge NFAS (p = 0.004). Endurance during non-nutritive sucking (p < 0.001) and nutritive sucking (p < 0.001) significantly improved. Nine participants (31.0%) demonstrated penetration or aspiration. Most aspiration events were silent (60%). Instrumental assessment identified pharyngeal phase dysphagia more effectively than bedside evaluation. High proportions of participants displayed OPD symptoms regardless of HIE severity. The correlation between OPD severity and the length of hospitalisation (p = 0.052) was not significant. CONCLUSION: All grades of HIE should be considered for early intervention by speech-language pathologists before discharge. Findings may be valuable to neonatal feeding teams.

RESUMEN

BACKGROUND: There is a shortage of validated autism screening tests in the 11 official languages of South Africa. The Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/FTM), a validated and well-known screening test, had already been adapted (in English) and translated into Northern Sotho for use in South Africa. OBJECTIVES: The aim was to collect pilot data to determine the preliminary reliability and feasibility of the two tests to confirm the equivalence of the adaptation and translation. METHOD: The study was conducted in a peri-urban community in South Africa. Twenty-one first-language Northern Sotho caregivers of children aged between 18 and 48 months were recruited by employing snowball sampling. The participants were asked to complete the Northern Sotho and the culturally adapted English M-CHAT-R/F, which were presented in random order. RESULTS: The preliminary content validity and equivalence were evident, with no difference at the 5% interval of the Wilcoxon signed rank test. All 21 toddlers screened presented with a low risk for autism following the recommended execution of the Follow-Up section for the toddlers in the medium risk category. All participants completed the two screening tests, with none indicating unfamiliar words or constructs. A higher preference for the English adapted version was found but a need for the Northern Sotho screening test was also evidentConclusion: The Northern Sotho translation of the M-CHAT-R/F, as well as the adapted English version, appears feasible and is ready for comprehensive validation.

RESUMEN

OBJECTIVE: To describe the developmental risks, and its influence, in young children from a low-income South African community. METHOD: An exploratory, cross-sectional research study design was employed. Developmental screening was conducted during home visits with 126 caregivers and children between 0 and 42 months of age from a low-income South African community. Children who failed the rescreen were referred for diagnostic assessment. A binomial logistic regression was used to determine the effect of developmental risks on developmental outcomes. RESULTS: Seventy-three percent of children screened were identified with a possible developmental delay (n = 59) according to caregiver-report using the PEDS tools. The regression model was statistically significant (χ2 (3) = 34.902, p < 0.001) with exposure to multiple languages (p < 0.05; odds ratio 3.810, CI 1.2-12.4) most indicative of potential developmental delay. Older children (19-42 months) were also more at risk of developmental delay (p < 0.001) than younger children (0-18 months). CONCLUSIONS FOR PRACTICE: Healthcare professionals serving these vulnerable populations should create awareness amongst caregivers about the effect of developmental risks, in particularly multiple language exposure, on development.

RESUMEN

Introduction Globally, more than 50 million children have hearing or vision loss. Most of these sensory losses are identified late due to a lack of systematic screening, making treatment and rehabilitation less effective. Mobile health (mHealth), which is the use of smartphones or wireless devices in health care, can improve access to screening services. mHealth technologies allow lay health workers (LHWs) to provide hearing and vision screening in communities. Purpose The aim of the study was to evaluate a hearing and vision school screening program facilitated by LHWs using smartphone applications in a low-income community in South Africa. Method Three LHWs were trained to provide dual sensory screening using smartphone-based applications. The hearScreen app with calibrated headphones was used to conduct screening audiometry, and the Peek Acuity app was used for visual acuity screening. Schools were selected from low-income communities (Gauteng, South Africa), and children aged between 4 and 9 years received hearing and vision screening. Screening outcomes, associated variables, and program costs were evaluated. Results A total of 4,888 and 4,933 participants received hearing and vision screening, respectively. Overall, 1.6% of participants failed the hearing screening, and 3.6% failed visual acuity screening. Logistic regression showed that female participants were more likely to pass hearing screening (OR = 1.61, 95% CI [1.11, 2.54]), while older children were less likely to pass visual acuity screening (OR = 0.87, 95% CI [0.79, 0.96]). A third (32.5%) of referred cases followed up for air-conduction threshold audiometry, and one in four (25.1%) followed up for diagnostic vision testing. A high proportion of these cases were confirmed to have hearing (73.1%, 19/26) or vision loss (57.8%, 26/45). Conclusions mHealth technologies can enable LHWs to identify school-age children with hearing and/or vision loss in low-income communities. This approach allows for low-cost, scalable models for early detection of sensory losses that can affect academic performance.

RESUMEN

Purpose Phonological awareness (PA) requires the complex integration of language, speech, and auditory processing abilities. Enhanced pitch and rhythm discrimination have been shown to improve PA and speech-in-noise (SiN) discrimination. The screening of pitch and rhythm discrimination, if nonlinguistic correlates of these abilities, could contribute to screening procedures prior to diagnostic assessment. This research aimed to determine the association of PA abilities with pitch, rhythm, and SiN discrimination in children aged 5-7 years old. Method Forty-one participants' pitch, rhythm, and SiN discrimination and PA abilities were evaluated. To control for confounding factors, including biological and environmental risk exposure and gender differences, typically developing male children from high socioeconomic statuses were selected. Pearson correlation was used to identify associations between variables, and stepwise regression analysis was used to identify possible predictors of PA. Results Correlations of medium strength were identified between PA and pitch, rhythm, and SiN discrimination. Pitch and diotic digit-in-noise discrimination formed the strongest regression model (adjusted R 2 = .4213, r = .649) for phoneme-grapheme correspondence. Conclusions The current study demonstrates predictive relationships between the complex auditory discrimination skills of pitch, rhythm, and diotic digit-in-noise recognition and foundational phonemic awareness and phonic skills in young males from high socioeconomic statuses. Pitch, rhythm, and digit-in-noise discrimination measures hold potential as screening measures for delays in phonemic awareness and phonic difficulties and as components of stimulation programs.

RESUMEN

Age-appropriate early childhood development is greatly influenced by exposure to various mediating and moderating factors. Developmental outcomes cannot be viewed in isolation, but by considering the interaction of the various risks and protective factors that influence early child development. A non-experimental, cross-sectional research design was employed. Data was collected in a low-income community in Gauteng, South Africa. Caregivers with children (n = 276) between the ages of 3 years and 6 years 11 months (mean 51.57 months; SD ± 12.4) whose children were in a preschool were invited to participate in the research study. Participants were divided into two groups, children with developmental delays and children without a developmental delay. The study sample included high risk, vulnerable preschool children, with a developmental delay prevalence of 80.1% (221/276). Families included were exposed to an average of five (SD ± 1.86) environmental and/or biological risks. According to a logistic regression model, three factors were significantly associated with increasing resilience amongst children with no developmental delay: living with both parents (p < 0.031, OR 4.5, 95% CI 1.2-17.2), caregivers having at least completed Grade 8 to 12 (p < 0.027, OR 11.9, 95% CI 1.4-10.5) and parents being married (p < 0.023, OR 5.1, 95% CI 1.3-20.9). Important protective factors in low-income communities like caregiver education, living with both parents and parental marriage can inform public health messaging and other population-based interventions to support early childhood development.
