Longitudinal cohort protocol study of oropharyngeal dysphagia: relationships to gross motor attainment, growth and nutritional status in preschool children with cerebral palsy

The evolution of nutrition management in children with severe neurological impairment with a focus on cerebral palsy

Nutritional management of children with severe neurological impairment (SNI) is highly complex, and the profile of this population is changing. The aim of this narrative review was to give the reader a broad description of evolution of the nutritional management of children with SNI in a high resource setting. In the last decade, there has been an emphasis on using multiple anthropometric measures to monitor nutritional status in children with SNI, and several attempts at standardising the approach have been made. Tools such as the Feeding and Nutrition Screening Tool, the Subjective Global Nutrition Assessment, the Eating and Drinking Ability Classification System and the Focus on Early Eating and Drinking Swallowing (FEEDS) toolkit have become available. There has been an increased understanding of how the gut microbiome influences gastrointestinal symptoms common in children with SNI, and the use of fibre in the management of these has received attention. A new diagnosis, 'gastrointestinal dystonia', has been defined. The increased use and acceptance of blended food tube feeds has been a major development in the nutritional management of children with SNI, with reported benefits in managing gastrointestinal symptoms. New interventions to support eating and drinking skill development in children with SNI show promise. In conclusion, as the life expectancy of people with SNI increases due to advances in medical and nutrition care, our approach necessitates a view to long-term health and quality of life. This involves balancing adequate nutrition to support growth, development and well-being while avoiding overnutrition and its associated detrimental long-term effects.

Neuromuscular adaptations of swallowing and speech in unilateral cerebral palsy: shared and distinctive traits

Our aims were to 1) examine the neuromuscular control of swallowing and speech in children with unilateral cerebral palsy (UCP) compared with typically developing children (TDC), 2) determine shared and separate neuromuscular underpinnings of the two functions, and 3) explore the relationship between this control and behavioral outcomes in UCP. Surface electromyography (sEMG) was used to record muscle activity from the submental and superior and inferior orbicularis oris muscles during standardized swallowing and speech tasks. The variables examined were normalized mean amplitude, time to peak amplitude, and bilateral synchrony. Swallowing and speech were evaluated using standard clinical measures. Sixteen children with UCP and 16 TDC participated (7-12 yr). Children with UCP demonstrated higher normalized mean amplitude and longer time to peak amplitude across tasks than TDC (P < 0.01; and P < 0.02) and decreased bilateral synchrony than TDC for swallows (P < 0.01). Both shared and distinctive neuromuscular patterns were observed between swallowing and speech. In UCP, higher upper lip amplitude during swallows was associated with shorter normalized mealtime durations, whereas higher submental bilateral synchrony was related to longer mealtime durations. Children with UCP demonstrate neuromuscular adaptations for swallowing and speech, which should be further evaluated for potential treatment targets. Furthermore, both shared and distinctive neuromuscular underpinnings between the two functions are documented.NEW & NOTEWORTHY Systematically studying the swallowing and speech of children with UCP is new and noteworthy. We found that they demonstrate neuromuscular adaptations for swallowing and speech compared with typically developing peers. We examined swallowing and speech using carefully designed tasks, similar in motor complexity, which allowed us to directly compare patterns. We found shared and distinctive neuromuscular patterns between swallowing and speech.

andomised to early neuroprotection and neurorehabilitation: protocol for a follow-up study of participants from four randomised clinical trials

INTRODUCTION

School readiness includes cognitive, socio-emotional, language and physical growth and development domains which share strong associations with life-course opportunities. Children with cerebral palsy (CP) are at increased risk of poor school readiness compared with their typically developing peers. Recently, earlier diagnosis of CP has allowed interventions to commence sooner, harnessing neuroplasticity. First, we hypothesise that early referral to intervention for children at-risk of CP will lead to improved school readiness at 4-6 years relative to placebo or care as usual. Second, we hypothesise that receipt of early diagnosis and early intervention will lead to cost-savings in the form of reduced healthcare utilisation.

METHODS AND ANALYSIS

Infants identified as at-risk of CP ≤6 months corrected age (n=425) recruited to four randomised trials of neuroprotectants (n=1), early neurorehabilitation (n=2) or early parenting support (n=1) will be re-recruited to one overarching follow-up study at age 4-6 years 3 months. A comprehensive battery of standardised assessments and questionnaires will be administered to assess all domains of school readiness and associated risk factors. Participants will be compared with a historical control group of children (n=245) who were diagnosed with CP in their second year of life. Mixed-effects regression models will be used to compare school readiness outcomes between those referred for early intervention versus placebo/care-as-usual. We will also compare health-resource use associated with early diagnosis and intervention versus later diagnosis and intervention.

ETHICS AND DISSEMINATION

The Children's Health Queensland Hospital and Health Service, The University of Queensland, University of Sydney, Monash University and Curtin University Human Research Ethics Committees have approved this study. Informed consent will be sought from the parent or legal guardian of every child invited to participate. Results will be disseminated in peer-reviewed journals, scientific conferences and professional organisations, and to people with lived experience of CP and their families.

Effect of oral motor facilitation technique on oral motor and feeding skills in children with cerebral palsy : a case study

Background:

Deficiencies in oral motor function and feeding skills are common in children with cerebral palsy (CP). Oral motor therapy is a useful method to improve oral motor function and feeding skills. Oral motor facilitation technique (OMFT) is a newly designed comprehensive oral motor therapy, including postural control, sensory adaptation, breathing control, sensorimotor facilitation, and direct feeding.

Methods:

This study was performed to identify the effect of OMFT on oral motor function and feeding skills in children with CP. A total of 21 children with CP (3–10 years, GMFCS III–V) participated in 16 weeks (16 sessions) of OMFT. The effects on oral motor function and feeding skills were assessed using the Oral Motor Assessment Scale (OMAS) before the treatment, 8 and 16 weeks after OMFT. Data were analyzed using the Friedman test and post-hoc analysis.

Results:

Significant improvement was found in oral motor function and feeding skills including mouth closure, lip closure on the utensil, lip closure during deglutition, control of the food during swallowing, mastication, straw suction, and control of liquid during deglutition after OMFT. Mouth closure was the most effective and mastication was the least effective item. Sixteen weeks is more effective than 8 weeks of OMFT.

Conclusion:

OMFT could be an effective and useful oral motor therapy protocol to improve oral motor function and feeding skills in children with CP.

From Mouth to Brain: Distinct Supragingival Plaque Microbiota Composition in Cerebral Palsy Children With Caries

Children with cerebral palsy (CP) present a higher prevalence and severity of caries. Although researchers have studied multiple risk factors for caries in CP, the role of microorganisms in caries remains one of the critical factors worth exploring. In order to explore the differences in the supragingival plaque microbiota (SPM), supragingival plaque samples were collected from 55 CP children and 23 non-CP children for 16S rRNA sequencing. Distinct SPM composition was found between CP children with severe caries (CPCS) and non-CP children with severe caries (NCPCS). Further subanalysis was also done to identify if there were any differences in SPM among CP children with different degrees of caries, namely, caries-free (CPCF), mild to moderate caries (CPCM), and severe caries (CPCS). After selecting the top 15 most abundant species in all groups, we found that CPCS was significantly enriched for Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, Porphyromonas endodontalis, Catonella morbi, Alloprevotella tannerae, Parvimonas micra, Streptobacillus moniliformis, and Porphyromonas canoris compared to NCPCS. By comparing CPCF, CPCM, and CPCS, we found that the core caries-associated microbiota in CP children included Prevotella, Alloprevotella, Actinomyces, Catonella, and Streptobacillus, while Capnocytophaga and Campylobacter were dental health-associated microbiota in CP children. Alpha diversity analysis showed no significant difference between NCPCS and CPCS, but the latter had a much simpler core correlation network than that of NCPCS. Among CP children, CPCM and CPCF displayed lower bacterial diversity and simpler correlation networks than those of CPCS. In summary, the study showed the specific SPM characteristics of CPCS compared to NCPCS and revealed the core SPM in CP children with different severities of caries (CPCF, CPCM, and CPCS) and their correlation network. Hopefully, the study would shed light on better caries prevention and therapies for CP children. Findings from the current study offer exciting insights that warrant larger cohort studies inclusive of saliva and feces samples to investigate the potential pathogenic role of oral microbiota through the oral–gut–brain axis in CP children with caries.

Videofluoroscopic Swallow Study Findings and Correlations in Infancy of Children with Cerebral Palsy

OBJECTIVES

Cerebral palsy (CP) in infants can affect global motor function and lead to swallowing difficulties. This study aims to characterize oral and pharyngeal swallowing dynamics in infancy of patients later diagnosed with CP and to determine if swallow study performance in early infancy is associated with later CP severity and characteristics.

METHODS

This is a retrospective chart review of infants who underwent videofluoroscopic swallow studies (VFSS) between 6/2008 and 10/2018 at a tertiary children's hospital, and were later diagnosed with CP. Demographic data, CP characteristics and metrics, and VFSS findings were collected and analyzed.

RESULTS

There were 66 patients included in this study. The average age at the time of VFSS was 4 months (range: 0.3-12 months), 42% of patients were female, and 50% of patients were born premature. In our sample, 86% of patients presented with oral dysphagia, and 76% with pharyngeal dysphagia. Laryngeal penetration in isolation was seen in 39% of patients, and tracheal aspiration was seen in 38% of patients. Of these tracheal aspiration events, 64% were silent. At the time of VFSS, 58% of patients had a nasogastric tube, 12% had a gastrostomy tube, and 3% had a prior hospitalization for pneumonia. Rates of penetration and aspiration in early infancy did not consistently correlate with prematurity, type of CP (spastic, non-spastic, or mixed), degree of paralysis (quadriplegic, hemiplegic, or diplegic), or severity of Gross Motor Function Classification System (GMFCS) score.

CONCLUSION

While there was not a consistent correlation of swallowing dynamics in infancy with later gross motor categorizations of CP, the results of this retrospective review highlight the essential role of early clinical and videofluoroscopic swallowing evaluations to identify oral and pharyngeal swallowing dysfunction in this patient population.

Efforts targeted malnutrition among children with cerebral palsy in care homes and hospitals: A qualitative exploration study

INTRODUCTION

Children with cerebral palsy (CP) are at risk of becoming malnourished. Malnutrition risk increases with increased gross motor function classification. The present study aimed to investigate and explore existing nutritional efforts and practice among staff in Danish hospitals and care homes working with children with CP.

METHODS

Ten qualitative interviews were generated with multidisciplinary staff working in hospital wards, care homes and Neuro Pediatric Team (NPT). Analysis was inspired by Braun and Clarke's thematic analysis.

RESULTS

The analysis generated the following six themes: Weighing and anthropometric measurements; Existing nutritional evaluation and intervention in practice; Cross-sectoral communication and interdisciplinarity; Involvement of the children's parents; Knowledge and professional intuition; and Time and priority. Weighing is the most common nutritional evaluation, supplemented by weight/height curves in the NPT. No actual screening is performed. In care homes without healthcare staff, the nutritional focus primarily regards the meal and how the children are able to eat. In care homes with health staff, as well as hospital departments, the focus is primarily on weight. Written communication is a necessity for the nutritional collaboration around the child to work, but collaboration between IT-systems are lacking. Interdisciplinarity and parental involvement are key components for managing nutrition issues among children with CP. The specialist dietitian was much required, but difficult to reach.

CONCLUSIONS

Despite the great focus on nutrition and nutritional status among children with CP in all of the inquired contexts, existing efforts for assessment reveal primarily on weight and intuition. No actual screening is performed. Collaboration between sectors and professionals is challenged by lacking IT-systems and systematic procedures.

What are parents' perceptions related to barriers in diagnosing swallowing dysfunction in children? A grounded theory approach

OBJECTIVES

Swallowing dysfunction (SwD) is under-reported in otherwise healthy infants and toddlers (OHITs). The identification of parental perceptions of factors that may hinder the diagnosis could help clinicians manage these children in a more expeditious manner. This study investigated the barriers to diagnosing SwD, as reported by the families.

DESIGN

Grounded theory study.

SETTING

This study was performed in a tertiary care paediatric centre in Canada.

PARTICIPANTS

Parents of OHITs were recruited using purposeful sampling.

INTERVENTION

We used detailed, semistructured, in-person interviews and the audiotapes and transcriptions were thematically analysed. From the parental insights, we built a framework composed of three themes of barriers.

RESULT

Ten parents of OHITs with SwD were interviewed. The children presented with recurrent coughing, choking, cold-like symptoms, recurring/consistent illnesses and feeding difficulties. They were managed with multiple rounds of antibiotics and diagnosed with allergies, asthma or recurrent viral infections before considering SwD. The three emerging themes are false beliefs about SwD among parents and some physicians, parent-related barriers and physician-related barriers. These barriers had severely impacted the parents, impairing work productivity and leading to work-related reprimands and changes in the family dynamics.

CONCLUSION

This study suggests that there are several barriers that face the parents of OHITs when seeking a diagnosis of SwD and initiating appropriate management. These barriers likely interact with one another and amplify their effects on the family and the child. A common denominator is a lack of education regarding SwD, its clinical manifestations and the available expertise to manage this condition.

The incidence rate of diabetes mellitus (type II) and its related risk factors: A 10-year longitudinal study of Yazd Healthy Heart Cohort (YHHC), Iran

BACKGROUND AND OBJECTIVES

Diabetes Mellitus (DM) is a metabolic disease characterized by chronic hyperglycemia, which occurs due to insufficient production of insulin by the pancreas or resistance to insulin produced by the body. The most dangerous and Long-term complications of diabetes include renal failure, heart failure, cardiovascular disease, stroke, diabetic foot ulcers, and diabetic neuropathy.

MATERIALS AND METHODS

This longitudinal cohort study was conducted on 1641 non-diabetic people of 2000 participants enrolled in phase I of Yazd Healthy Heart project (YHHP) aged 20-74 year-old resident of the city of Yazd. They were selected randomly through cluster sampling method and included in follow up a project for ten years (2004-2014). In order to analyze the data, Chi-Square, independent t-test and logistic regression statistical models were used through the SPSS Ver₂₀.

RESULTS

The incidence rate of DM type II among the people aged 20-74 years in Yazd was 21.4 per 1000 of a population-year. Univariate analysis revealed that the relative risk of DM incidence increased by smoking, increasing BMI, abdominal obesity, hypertension, and increased cholesterol, triglyceride and uric acid levels (p < 0.0001). Variables with a significant p-value < 0.05 using the univariate analysis were included in the logistic regression model. Age, family history of diabetes mellitus in relatives, abdominal obesity, triglyceride values greater than 150 and uric acid more than the 75th percentile were recognized as independent risk factors of diabetes.

CONCLUSION

In the present study, Age, family history of DM, abdominal obesity, high triglycerides, and high uric acid are the most important risk factors for diabetes.

Reliability, construct validity and usability of the Eating and Drinking Ability Classification System (EDACS) among Dutch children with Cerebral Palsy

PURPOSE

To assess the interrater reliability, construct validity and usability of the Eating and Drinking Ability Classification System (EDACS) among Dutch children with Cerebral Palsy (CP) when used by speech and language therapists (SLTs) familiar and unfamiliar with the child's eating and drinking performance and parents.

METHODS

Translation was undertaken using the method of Eremenco. Agreement between SLTs and parents when using EDACS was determined by intraclass correlation coefficient (ICC) and linear weighted Kappa (κW). Associations with other functional classification systems including the Dysphagia Management Staging Scale (DMSS) were investigated to determine construct validity by Kendall's tau-b.

RESULTS

Thirty-one SLTs classified 149 children (67 girls; mean 10 y, SD 4 y, range 3-21 y) with EDACS. Pairs of SLTs showed good agreement ([ICC] = 0.84; 95% confidence interval [CI] 0.79-0.88; [κW] = 0.71). Eighty-one parents showed good agreement with SLTs (n= 31) as well (ICC = 0.80; 95% CI 0.71-0.87; κW= 0.61). There was a significant and strong positive correlation of EDACS with DMSS (Kendall's tau-b 0.81) supporting its construct validity. Usability of EDACS was generally good.

CONCLUSION

The Dutch version of EDACS is reliable and valid, and can be used easily by (familiar and unfamiliar) SLTs and parents of children with CP. Parents and professionals showed a high level of consistency when classifying eating and drinking abilities. EDACS enables uniform and efficient communication about safety and efficiency of functional eating and drinking ability in clinical and research contexts.

Oropharyngeal Dysphagia and Cerebral Palsy

OBJECTIVES

To determine the progression of oropharyngeal dysphagia (OPD) in preschool-aged children with cerebral palsy (CP) according to gross motor function. It was hypothesized that fewer children would have OPD at 60 months compared with 18 to 24 months (predominately Gross Motor Function Classification System [GMFCS] I-II).

METHODS

Longitudinal population-based cohort of 179 children (confirmed CP diagnosis, born in Queensland in 2006-2009, aged 18-60 months at study entry [mean = 34.1 months ± 11.9; 111 boys; GMFCS I = 46.6%, II = 12.9%, III = 15.7%, IV = 10.1%, and V = 14.6%]). Children had a maximum of 3 assessments (median = 3, total n = 423 assessments). OPD was classified by using the Dysphagia Disorders Survey part 2 and rated from video by a certified pediatric speech pathologist. GMFCS was used to classify children's gross motor function.

RESULTS

OPD prevalence reduced from 79.7% at 18 to 24 months to 43.5% at 60 months. There were decreasing odds of OPD with increasing age (odds ratio [OR] = 0.92 [95% confidence interval (CI) 0.90 to 0.95]; P < .001) and increasing odds with poorer gross motor function (OR = 6.2 [95% CI 3.6 to 10.6]; P < .001). This reduction was significant for children with ambulatory CP (GMFCS I-II, OR = 0.93 [95% CI 0.90 to 0.96]; P < .001) but not significant for children from GMFCS III to V (OR [III] = 1.0 [95% CI 0.9 to 1.1]; P = .897; OR [IV-V] = 1.0 [95% CI 1.0 to 1.1]; P = .366).

CONCLUSIONS

Half of the OPD present in children with CP between 18 and 24 months resolved by 60 months, with improvement most common in GMFCS I to II. To more accurately detect and target intervention at children with persisting OPD at 60 months, we suggest using a more conservative cut point of 6 out of 22 on the Dysphagia Disorders Survey for assessments between 18 and 48 months.

Evaluation of Feeding Disorders Including Gastro-Esophageal Reflux and Oropharyngeal Dysfunction in Children With Cerebral Palsy

Objective: This cross sectional study aims to survey developing feeding disorders and nutritional deficiencies disorders in children with neurodevelopmental disorders such as cerebral palsy. Materials and methods: A total of 50 children (28 boys and 22 girls) with cerebral palsy and symptoms suggesting gastrointestinal problems such as choking, recurrent pneumonia and poor weight gain, who referred to the Pediatric department of Vali-asr Hospital, Imam Khomeini hospital complex between 1 October 2012 and 30 October 2013, were checked. Motor function classification system was used to classify patient's functional gross motor severity. All patients were examined and underwent deglutition videofluroscopy (modified barium swallow) and upper GI endoscopy with esophageal biopsies. Outcome of this study was the prevalence of oropharyngeal incoordination and GERD. Its relationship with some variables like motor and cognitive developmental delay were analyzed and p value < 0.05 was considered significant. Medical therapy and/or oral physiotherapy and nutritional rehabilitation were started. They were examined after 6 months of treatment. Decrease in choking and episodes of respiratory infections that needed hospitalization and weight gain after 6 months treatment were considered as secondary outcomes (response to treatment). Results: Prevalence of GERD was 66% and oropharyngeal dysphagia was estimated 82%. According to results of video-fluroscopy and endoscopic biopsies, 52% of patients were affected by both GERD and oropharyngeal dysfunction. The gross motor function disability was the only variable that significantly related to the prevalence of feeding disorders (p = 0.015). Despite nutritional rehabilitation only 46% of children have weight gain. Conclusion: Feeding disorders such as GERD and oropharyngeal dysfunction are more prevalent in children with cerebral palsy especially in children with severe gross motor disabilities. Since, clinical manifestations of these disorders can be similar accurate diagnostic methods should be selected for all children with cerebral palsy and gastrointestinal symptoms. Treatment should start early to reduce the complications and improve outcomes.

[Evaluation of dysphagia. Results after one year of incorporating videofluoroscopy into its study]

INTRODUCTION

Dysphagia is very common in children with neurological disabilities. These patients usually suffer from respiratory and nutritional problems. The videofluoroscopic swallowing study (VFSS) is the most recommended test to evaluate dysphagia, as it shows the real situation during swallowing.

OBJECTIVES

To analyse the results obtained in our centre after one year of the implementation of VFSS, the clinical improvement after confirmation, and the prescription of an individualised treatment for the patients affected.

MATERIAL AND METHODS

VFSS performed in the previous were collected. The following variables were analysed: age, pathology, degree of neurological damage, oral and pharyngeal and/or oesophageal dysphagia and its severity, aspirations, prescribed treatment, and nutritional and respiratory improvement after diagnosis. A statistical analysis was performed using SPSS v21.

RESULTS

A total of 61 VFSS were performed. Dysphagia was detected in more than 70%, being moderate-severe in 58%. Aspirations and/or penetrations were recorded in 59%, of which 50% were silent. Adapted diet was prescribed to 56%, and gastrostomy was performed on 13 (21%) patients. A statistical association was found between neurological disease and severity of dysphagia. The degree of motor impairment is related to the presence of aspirations. After VFSS evaluation and treatment adjustment, nutritional improvement was found in Z-score of weight (+0.3SD) and BMI (+0.4SD). There was respiratory improvement in 71% of patients with dysphagia being controlled in the Chest Diseases Department.

CONCLUSIONS

After implementation of VFSS, a high percentage of patients were diagnosed and benefited from a correct diagnosis and treatment. VFSS is a fundamental diagnostic test that should be included in paediatric centres as a diagnostic method for children with suspected dysphagia.

Parent-reported indicators for detecting feeding and swallowing difficulties and undernutrition in preschool-aged children with cerebral palsy

AIM

To determine the most accurate parent-reported indicators for detecting (1) feeding/swallowing difficulties and (2) undernutrition in preschool-aged children with cerebral palsy (CP).

METHOD

This was a longitudinal, population-based study, involving 179 children with CP, aged 18 to 60 months (mean 34.1mo [SD 11.9] at entry, 111 males, 68 females [Gross Motor Function Classification System level I, 84; II, 23; III, 28; IV, 18; V, 26], 423 data points). Feeding/swallowing difficulties were determined by the Dysphagia Disorders Survey and 16 signs suggestive of pharyngeal phase impairment. Undernutrition was indicated by height-weight and skinfold composite z-scores less than -2. Primary parent-reported indicators included mealtime duration, mealtime stress, concern about growth, and respiratory problems. Other indicators were derived from a parent feeding questionnaire, including 'significant difficulty eating and drinking'. Data were analysed using multilevel mixed-effects regression and diagnostic statistics.

RESULTS

Primary parent-reported indicators associated with feeding/swallowing were 'moderate-severe parent stress' (odds ratio [OR]=3.2 [95% confidence interval {CI} 1.3-7.8]; p<0.01), 'moderate-severe concern regarding growth' (OR=4.5 [95% CI 1.7-11.9]; p<0.01), and 'any respiratory condition' (OR=1.8 [95% CI 1.4-5.8]; p<0.01). The indicator associated with undernutrition was 'moderate-severe concern regarding growth' (height-weight OR=13.5 [95% CI 3.0-61.3]; p<0.01; skinfold OR=19.1 [95% CI 3.7-98.9]; p<0.01). 'Significant difficulty eating and drinking' was most sensitive/specific for feeding outcome (sensitivity=58.6%, specificity=100.0%), and 'parent concern regarding growth' for undernutrition (sensitivity=77.8%, specificity=77.0%).

INTERPRETATION

Parent-reported indicators are feasible for detecting feeding and swallowing difficulties and undernutrition in children with CP, but need formal validation.

WHAT THIS PAPER ADDS

Parent-reported indicators can detect feeding/swallowing difficulties and undernutrition in children with cerebral palsy. Most accurate screening questions were 0-10 scales for 'difficulty eating' and 'difficulty drinking'. Supplementation of these scales with additional indicators would improve detection.

Parental Perception of Comorbidities in Children With Dravet Syndrome

BACKGROUND

We hypothesized that children with Dravet syndrome may have additional common features beyond seizures and cognitive impairment. To address this gap in knowledge, we conducted a survey of caregivers of children with Dravet syndrome to identify and quantify their perception of associated symptoms in this population.

METHODS

An electronic survey was developed in REDcap (Research Electronic Data Capture) and sent via e-mail to the participants on the Dravet Syndrome Foundation e-mail list. Questions focused on eating, sleep, behavior, and other symptoms that might be related to Dravet syndrome. The questions were assessed using a four-point Likert scale (e.g., strongly agree to strongly disagree). Results were later dichotomized for analysis. Logistic regression was used to calculate odds ratios of various demographic factors potentially associated with symptoms. Multivariable models were constructed using backward elimination to assess the relationship among a variety of symptoms.

RESULTS

There were 202 respondents, 96% were parents of a child with Dravet syndrome (the remainder were grandparents or guardians); 90.5% were female. The median age of the affected child was eight years (interquartile range five to 14), 50% were male, and 90.5% were reported to have a known SCN1A mutation. At least one symptom associated with appetite was reported in 99% of respondents, 82% reported a disturbance of sleep, one third reported autonomic symptoms, and 75% reported problems with gait. Inattention and perseveration were reported more commonly than other behavioral disturbances.

SIGNIFICANCE

Caregivers have the perception of many symptoms in children with Dravet syndrome in addition to those that have been previously reported, including appetite, sleep, gait, and behavior. Many of these can significantly affect quality of life for both the child and the caregiver.

PREDICT-CP: study protocol of implementation of comprehensive surveillance to predict outcomes for school-aged children with cerebral palsy

OBJECTIVES

Cerebral palsy (CP) remains the world's most common childhood physical disability with total annual costs of care and lost well-being of $A3.87b. The PREDICT-CP (NHMRC 1077257 Partnership Project: Comprehensive surveillance to PREDICT outcomes for school age children with CP) study will investigate the influence of brain structure, body composition, dietary intake, oropharyngeal function, habitual physical activity, musculoskeletal development (hip status, bone health) and muscle performance on motor attainment, cognition, executive function, communication, participation, quality of life and related health resource use costs. The PREDICT-CP cohort provides further follow-up at 8-12 years of two overlapping preschool-age cohorts examined from 1.5 to 5 years (NHMRC 465128 motor and brain development; NHMRC 569605 growth, nutrition and physical activity).

METHODS AND ANALYSES

This population-based cohort study undertakes state-wide surveillance of 245 children with CP born in Queensland (birth years 2006-2009). Children will be classified for Gross Motor Function Classification System; Manual Ability Classification System, Communication Function Classification System and Eating and Drinking Ability Classification System. Outcomes include gross motor function, musculoskeletal development (hip displacement, spasticity, muscle contracture), upper limb function, communication difficulties, oropharyngeal dysphagia, dietary intake and body composition, participation, parent-reported and child-reported quality of life and medical and allied health resource use. These detailed phenotypical data will be compared with brain macrostructure and microstructure using 3 Tesla MRI (3T MRI). Relationships between brain lesion severity and outcomes will be analysed using multilevel mixed-effects models.

ETHICS AND DISSEMINATION

The PREDICT-CP protocol is a prospectively registered and ethically accepted study protocol. The study combines data at 1.5-5 then 8-12 years of direct clinical assessment to enable prediction of outcomes and healthcare needs essential for tailoring interventions (eg, rehabilitation, orthopaedic surgery and nutritional supplements) and the projected healthcare utilisation.

The Eating and Drinking Ability Classification System in a population-based sample of preschool children with cerebral palsy

AIM

To determine (1) the reproducibility of the Eating and Drinking Ability Classification System (EDACS); (2) EDACS classification distribution in a population-based cohort with cerebral palsy (CP); and (3) the relationships between the EDACS and clinical mealtime assessment, other classifications, and health outcomes.

METHOD

This was a cross-sectional population-based cohort study of 170 children with CP at 3 years to 5 years (mean 57.6mo, standard deviation [SD] 8.3mo; 105 males, n=65 females). Functional abilities were representative of a population sample (Gross Motor Function Classification System level I=74, II=34, III=21, IV=18, V=23). The EDACS was the primary classification of mealtime function. The Dysphagia Disorders Survey was the clinical mealtime assessment. Gross motor function was classified using the Gross Motor Function Classification System.

RESULTS

EDACS classification had 88.3% intrarater agreement (κ=0.84, intraclass correlation coefficient=0.95; p<0.001) and 51.7% interrater agreement (κ=0.36, intraclass correlation coefficient=0.79; p<0.001). In total, 56.5% of children were classified as EDACS level I. There was a strong stepwise relationship between the Dysphagia Disorders Survey and EDACS (r=0.96, p<0.001). Parental stress (odds ratio=1.3, p=0.05) and feeding tubes (odds ratio=6.4, p<0.001) were significantly related to more limited function on the EDACS.

INTERPRETATION

The EDACS presents a viable adjunct to clinical assessment of feeding skills in children with CP for use in surveillance trials and clinical practice. A rating addendum would be a useful contribution to the tool to enhance reproducibility.

Multiple Nutritional Deficiencies in Cerebral Palsy Compounding Physical and Functional Impairments

Introduction:

Cerebral palsy (CP) refers to a spectrum of disorders causing physical and intellectual morbidity. Macro and micro nutrient deficiencies often contribute to the subnormal physical and mental capabilities of them.

Objectives:

To assess the growth, nutritional status, physical and functional ability and quality of life in cerebral palsy children and to determine any relation with their gross motor and functional capabilities.

Method:

The study was conducted at a Tertiary Care Centre, with the participants in the age group 1-16 years. A pretested evaluation tool was prepared which included Anthropometric measurements, tests for hemoglobin and Vitamin D estimation, evidence of micronutrient deficiencies, Dietary patterns, Epidemiological factors, Functional assessment using GMFM (Gross Motor Function Measure ) and FIM (Functional Independent Measurement) scales and Quality of life (QOL) assessment. The data was statistically analyzed.

Results:

Out of the 41 children, 30 had quadriplegia, 3 had hemiplegia and 8 had spastic diplegia. 34 (82.9%) were severely underweight, 35 (85.4%) had severe stunting and 38 (92.7%) had severe wasting. Micronutrient deficiencies were noted like vitamin B complex deficiency in 37 (90.2%), vitamin A deficiency in 31 (75.6%), low vitamin D levels in 27 (65.9%) and insufficient levels in 9 (22%), severe anemia in 5 (12.2%) and moderate anemia in 26 (63.4%). The gross motor and functional scores were suboptimum in the majority of patients and the care givers had significant impairment in the quality of life.

Conclusion:

Majority of children with cerebral palsy had multiple nutritional deficiencies, gross motor and functional disabilities. QOL of the children and their care givers were suboptimum. A comprehensive package that address dietary intake, correction of micronutrient deficiencies especially anemia and vitamin D deficiency, physical and emotional support is recommended for the wellbeing of the affected children.

Oropharyngeal dysphagia in children with cerebral palsy: comparisons between a high- and low-resource country

PURPOSE

There is paucity of research investigating oropharyngeal dysphagia (OPD) in young children with cerebral palsy (CP), and most studies explore OPD in high-resource countries. This study aimed at determining the proportion and severity of OPD in preschool children with CP in Bangladesh, compared to Australia.

METHOD

Cross-sectional, comparison of two cohorts. Two hundred and eleven children with CP aged 18-36 months, 81 in Bangladesh (mean = 27.6 months, 61.7% males), and 130 in Australia (mean = 27.4 months, 62.3% males). The Dysphagia Disorders Survey (DDS) - Part 2 was the primary OPD outcome for proportion and severity of OPD. Gross motor skills were classified using the Gross Motor Function Classification System (GMFCS), motor type/distribution.

RESULTS

(i) Bangladesh sample: proportion OPD = 68.1%; severity = 10.4 SD = 7.9. Australia sample: proportion OPD = 55.7%; severity = 7.0 SD = 7.5. (ii) There were no differences in the proportion or severity of OPD between samples when stratified for GMFCS (OR = 2.4, p = 0.051 and β = 1.2, p = 0.08, respectively).

CONCLUSIONS

Despite overall differences in patterns of OPD between Bangladesh and Australia, proportion and severity of OPD (when adjusted for the functional gross motor severity of the samples) were equivalent. This provides support for the robust association between functional motor severity and OPD proportion/severity in children with CP, regardless of the resource context. Implications for Rehabilitation The proportion and severity of OPD according to gross motor function level were equivalent between high- and low-resource countries (LCs). Literature from high-resource countries may be usefully interpreted by rehabilitation professionals for low-resource contexts using the GMFCS as a framework. The GMFCS is a useful classification in LCs to improve earlier detection of children at risk of OPD and streamline management pathways for optimal nutritional outcomes. Rehabilitation professionals working in LCs are likely to have a caseload weighted towards GMFCS III-V, with less compensatory OPD management options available (such as non-oral nutrition through tubes).

Longitudinal Study of Oropharyngeal Dysphagia in Preschool Children With Cerebral Palsy

OBJECTIVES

To determine changes in prevalence and severity of oropharyngeal dysphagia (OPD) in children with cerebral palsy (CP) and the relationship to health outcomes.

DESIGN

Longitudinal cohort study.

SETTING

Community and tertiary institutions.

PARTICIPANTS

Children (N=53, 33 boys) with a confirmed diagnosis of CP assessed first at 18 to 24 months (Assessment 1: mean age ± SD, 22.9±2.9 mo corrected age; Gross Motor Function Classification System [GMFCS]: I, n=22; II, n=7; III, n=11; IV, n=5; V, n=8) and at 36 months (Assessment 2).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

OPD was classified using the Dysphagia Disorders Survey (DDS) and signs suggestive of pharyngeal dysphagia. Nutritional status was measured using Z scores for weight, height, and body mass index (BMI). Gross motor skills were classified on GMFCS and motor type/distribution.

RESULTS

Prevalence of OPD decreased from 62% to 59% between the ages of 18 to 24 months and 36 months. Thirty percent of children had an improvement in severity of OPD (greater than smallest detectable change), and 4% had worse OPD. Gross motor function was strongly associated with OPD at both assessments, on the DDS (Assessment 1: odds ratio [OR]=20.3, P=.011; Assessment 2: OR=28.9, P=.002), pharyngeal signs (Assessment 1: OR=10.6, P=.007; Assessment 2: OR=15.8, P=.003), and OPD severity (Assessment 1: β=6.1, P<.001; Assessment 2: β=5.5, P<.001). OPD at 18 to 24 months was related to health outcomes at 36 months: low Z scores for weight (adjusted β=1.2, P=.03) and BMI (adjusted β=1.1, P=.048), and increased parent stress (adjusted OR=1.1, P=.049).

CONCLUSIONS

Classification and severity of OPD remained relatively stable between 18 to 24 months and 36 months. Gross motor function was the best predictor of OPD. These findings contribute to developing more effective screening processes that consider critical developmental transitions that are anticipated to present challenges for children from each of the GMFCS levels.

Food and fluid texture consumption in a population-based cohort of preschool children with cerebral palsy: relationship to dietary intake

AIM

To determine the texture constitution of children's diets and its relationship to oropharyngeal dysphagia (OPD), dietary intake, and gross motor function in young children with cerebral palsy (CP).

METHOD

A cross-sectional, population-based cohort study comprising 99 young children with CP (65 males, 35 females) aged 18 to 36 months (mean age 27mo; Gross Motor Function Classification System [GMFCS] level I, n=45; II, n=13; III, n=14; IV, n=10; V, n=17). CP subtypes were classified as spastic unilateral (n=35), spastic bilateral (n=49), dyskinetic (n=5), and other (n=10), in accordance with the criteria of the Surveillance of Cerebral Palsy in Europe. Habitual dietary intake of food textures, energy, and water were determined from parent-completed 3-day weighed food records. Parent-reported feeding ability of food textures was reported on the Pediatric Evaluation of Disability Inventory and a feeding questionnaire. OPD was classified based on clinical feeding assessment using the Dysphagia Disorders Survey (rated by a certified assessor, KAB) and a subjective Swallowing Safety Recommendation (classified by a paediatric speech pathologist, KAB).

RESULTS

Food/fluid textures were modified for 39% of children. Children with poorer gross motor function tended to receive a greater proportion of energy from fluids (GMFCS levels IV-V: β=0.9, p=0.002) in their diets and fewer chewable foods (level III: β=-0.7, p=0.03; levels IV-V: β=-1.8, p<0.001) compared to level I to II participants. Fluids represented a texture for which children frequently had OPD and the texture most frequently identified as unsafe (or recommended for instrumental assessment).

INTERPRETATION

These findings indicate that swallowing safety, feeding efficiency, and energy/water intake should be considered when providing feeding recommendations for children with CP.

Validity and reproducibility of measures of oropharyngeal dysphagia in preschool children with cerebral palsy

AIM

The aim of the study was to determine the best measure to discriminate between those with oropharyngeal dysphagia (OPD) and those without OPD, among young children with cerebral palsy (CP).

METHOD

We carried out a cross-sectional population-based study involving 130 children with CP aged between 18 months and 36 months (mean 27.4mo; 81 males, 49 females) classified according to the Gross Motor Function Classification Scale (GMFCS) as level I (n=57), II (n=15), III (n=23), IV (n=12), or V (n=23). Forty children with CP (mean 28.5mo; 21 males,19 females, eight for each GMFCS level) were included in the reproducibility sub-study, and 40 children with typical development (mean 26.2mo; 18 males, 22 females) were included in the validity sub-study. OPD was assessed using the Dysphagia Disorders Survey (DDS), Pre-Speech Assessment Scale (PSAS), and Schedule for Oral Motor Assessment (SOMA). We analysed reproducibility using inter- and intrarater agreement (percentage) and reliability (kappa values and intraclass correlation coefficients). Construct validity was assessed as concordance between measures (SOMA, DDS, and PSAS). In the absence of a criterion standard measure for OPD, prevalence was estimated using latent class variable analysis. Data from the children with typical development were used to propose modified OPD cut-points for discriminative validity.

RESULTS

All measures had strong agreement (>85%) for inter- and intrarater reliability. The SOMA had the best specificity (100.0%), but lacked sensitivity (53.0%), whereas the DDS and PSAS had high sensitivity (each 100.0%) but lacked specificity (47.1% and 70.6% respectively). OPD prevalence when calculated using the web-based estimation was 65.4%, which was similar to the estimate from the modified cut-points.

INTERPRETATION

Using the sample of children with typical development and modified cut-points, OPD prevalence was lower than estimates with standard scoring. We propose using these modified cut-points when administering the DDS, PSAS or SOMA in young children with CP.

Clinical signs suggestive of pharyngeal dysphagia in preschool children with cerebral palsy

This study aimed to determine the discriminative validity, reproducibility, and prevalence of clinical signs suggestive of pharyngeal dysphagia according to gross motor function in children with cerebral palsy (CP). It was a cross-sectional population-based study of 130 children diagnosed with CP at 18-36 months (mean=27.4, 81 males) and 40 children with typical development (TD, mean=26.2, 18 males). Sixteen signs suggestive of pharyngeal phase impairment were directly observed in a videoed mealtime by a speech pathologist, and reported by parents on a questionnaire. Gross motor function was classified using the Gross Motor Function Classification System. The study found that 67.7% of children had clinical signs, and this increased with poorer gross motor function (OR=1.7, p<0.01). Parents reported clinical signs in 46.2% of children, with 60% agreement with direct clinical mealtime assessment (kappa=0.2, p<0.01). The most common signs on direct assessment were coughing (44.7%), multiple swallows (25.2%), gurgly voice (20.3%), wet breathing (18.7%) and gagging (11.4%). 37.5% of children with TD had clinical signs, mostly observed on fluids. Dysphagia cut-points were modified to exclude a single cough on fluids, with a modified prevalence estimate proposed as 50.8%. Clinical signs suggestive of pharyngeal dysphagia are common in children with CP, even those with ambulatory CP. Parent-report on 16 specific signs remains a feasible screening method. While coughing was consistently identified by clinicians, it may not reflect children's regular performance, and was not sufficiently discriminative in children aged 18-36 months.

Oropharyngeal dysphagia in preschool children with cerebral palsy: oral phase impairments

PURPOSE

This study aimed to document the prevalence and patterns of oral phase oropharyngeal dysphagia (OPD) in preschool children with cerebral palsy (CP), and its association with mealtime duration, frequency and efficiency.

METHODS

Cross-sectional population-based cohort study of 130 children diagnosed with CP at 18-36 months ca (mean = 27.4 months, 81 males) and 40 children with typical development (mean = 26.2, 18 males). Functional abilities of children with CP were representative of a population sample (GMFCS I = 57, II = 15, III = 23, IV = 12, V = 23). Oral phase impairment was rated from video using the Dyspahgia Disorders Survey, Schedule for Oral Motor Impairment, and Pre-Speech Assessment Scale. Parent-report was collected on a feeding questionnaire. Mealtime frequency, duration and efficiency were calculated from a three day weighed food record completed by parents. Gross motor function was classified using the Gross Motor Function Classification System (GMFCS).

RESULTS

Overall, 93.8% of children had directly assessed oral phase impairments during eating or drinking, or in controlling saliva (78.5% with modified cut-points). Directly assessed oral phase impairments were associated with declining gross motor function, with children from GMFCS I having a 2-fold increased likelihood of oral phase impairment compared to the children with TD (OR = 2.0, p = 0.18), and all children from GMFCS II-V having oral phase impairments. Difficulty biting (70%), cleaning behaviours (70%) and chewing (65%) were the most common impairments on solids, and difficulty sipping from a cup (60%) for fluids. OPD severity and GMFCS were not related to mealtime frequency, duration or efficiency, although children on partial tube feeds had significantly reduced mealtime efficiency.

CONCLUSIONS

Oral phase impairments were common in preschool children with CP, with severity increasing stepwise with declining gross motor function. The prevalence and severity of oral phase impairments were significantly greater for most tasks when compared to children with typical development, even for those with mild CP. Children who were partially tube fed had significantly lower feeding efficiency, so this could be a useful early indicator of children needing supplementation to their nutrition (through increasing energy density of foods/fluids, or tube feeds).

The dysphagia disorder survey: validation of an assessment for swallowing and feeding function in developmental disability

Swallowing and feeding disorder (dysphagia) have high incidence and prevalence in children and adults with developmental disability. Standardized screening and clinical assessments are needed to identify and describe the disorder. The aim of this study was to describe the psychometric properties of the Dysphagia Disorder Survey (DDS), a screening and clinical assessment of swallowing and feeding function for eating and drinking developed specifically for this population. The statistical analysis was performed on a sample of 654 individuals (age range 8-82) with intellectual and developmental disability living in two residential settings in the United States that served somewhat different populations. The two samples had similar factor structures. Internal consistency of the DDS and subscales was confirmed using Chronbach's coefficient alpha. The DDS demonstrated convergent validity when compared to judgments of swallowing and feeding disorder severity made by clinical swallowing specialists. Discriminative validity for severity of disorder was tested by comparing the two samples. The results of the study suggest that the DDS is a reliable and valid test for identifying and describing swallowing and feeding disorder in children and adults with developmental disability.

Surface electromyography for diagnosing dysphagia in patients with cerebral palsy

AIM: To determine the accuracy of 2-channel surface electromyography (sEMG) for diagnosing oropharyngeal dysphagia (OPD) in patients with cerebral palsy.

METHODS: Participants with cerebral palsy and OPD between 5 and 30 years of age and age- and sex-matched healthy individuals received sEMG testing during swallowing. Electrodes were placed over the submental and infrahyoid muscles, and sEMG recordings were made during stepwise (starting at 3 mL) determination of maximum swallowing volume. Outcome measures included submental muscle group maximum amplitude, infrahyoid muscle group maximum amplitude (IMGMA), time lag between the peak amplitudes of 2 muscle groups, and amplitude difference between the 2 muscle groups.

RESULTS: A total of 20 participants with cerebral palsy and OPD (OPD group) and 60 age- and sex-matched healthy volunteers (control group) were recruited. Among 20 patients with OPD, 19 had Dysphagia Outcome and Severity Scale records. Of them, 8 were classified as severe dysphagia (level 1), 1 was moderate dysphagia (level 3), 4 were mild to moderate dysphagia (level 4), 3 were mild dysphagia (level 5), and 3 were within functional limits (level 6). Although the groups were matched for age and sex, participants in the OPD group were significantly shorter, weighed less and had lower body mass index than their counterparts in the control group (both, P < 0.001). All sEMG parameter values were significantly higher in the OPD group compared with the control group (P < 0.05). Differences were most pronounced at the 3 mL swallowing volume. IMGMA at the 3 mL volume was the best predictor of OPD with a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 85.0%, 90.0%, 73.9%, 94.7% and 88.8%, respectively.

CONCLUSION: Two-channel sEMG may be useful in the diagnosis of OPD in patients with cerebral palsy.
