Effect of oral sensorimotor treatment on measures of growth, eating efficiency and aspiration in the dysphagic child with cerebral palsy

Paediatric oral sensorimotor interventions for chewing dysfunction: A scoping review

BACKGROUND

Chewing dysfunction can have adverse effects on growth, development and quality of life. There is a lack of evidence-based consensus guidelines for sensorimotor intervention. To address this, we need to understand the current state of the science in clinical sensorimotor interventions for paediatric chewing dysfunction and systematically plan a research agenda and priorities for the field.

AIMS

The purpose of this scoping review was to examine the extent, range and nature of evidence for oral sensorimotor interventions for paediatric chewing dysfunction.

METHODS & PROCEDURES

This scoping review entailed five phases that included: identification of the research question; identification of relevant studies; study selection; data charting; and collation, summarization and report of the results. Treatment studies that were peer-reviewed and written in English were included. All studies involved a paediatric population and included an oral sensorimotor and/or chewing intervention. Information regarding study design, population, intervention, comparator, outcome measures and findings were extracted.

MAIN CONTRIBUTION

Of the 21 studies included in this scoping review, 53% were specific to children with cerebral palsy. All interventions were multi-component in nature and the treatment studies included a range of study designs, but few were controlled trials with comparators. A wide variety of outcomes measures were used within and across studies to determine treatment effectiveness.

CONCLUSIONS & IMPLICATIONS

The findings suggest that in a small number of studies, sensorimotor interventions provide preliminary evidence for effectiveness in specific populations. These and other treatment protocols must be trialled in additional clinical populations and settings to improve the evidence base for sensorimotor treatment of paediatric chewing dysfunction. This review also serves to help prioritize research agendas and further motivates the need for consensus-based clinical guidelines for paediatric chewing treatment.

WHAT THIS PAPER ADDS

What is already known on the subject Paediatric feeding disorders are highly prevalent and children often have chewing dysfunction that results in significant negative consequences. We lack evidence-based sensorimotor treatment approaches for chewing dysfunction, which directly impacts the care clinicians can provide children. What this study adds to existing knowledge This scoping review is the first step in examining the literature to understand the current state of the science for oral sensorimotor interventions for paediatric chewing dysfunction. Few randomized controlled studies were identified and a majority included children with cerebral palsy. Most of the interventions were multi-component and included a variety of treatment approaches. What are the potential or actual clinical implications of this work? The results of this scoping review can be used as an initial reference for clinicians selecting treatment approaches for chewing dysfunction. It also serves to help prioritize research agendas and further motivates the need for consensus-based clinical guidelines for paediatric chewing treatment.

The effect of a practical nutrition education programme on feeding skills of caregivers of children with cerebral palsy at Muhimbili National Hospital, in Tanzania

BACKGROUND

Feeding children with cerebral palsy (CP) is challenging and can lead to poor health outcomes. Using a facility-based intervention, we assessed the effect of a practical nutrition programme on feeding skills in caregivers of children with CP attending a pediatric clinic in urban Tanzania.

METHODS

A randomized-controlled intervention study, involving 2-block stratified sample of under-5 CP children attending a specialized pediatric clinic at the Muhimbili National Hospital was done. One hundred ten moderate-to-severe, new and follow-up cases of children with CP were randomly allocated to the intervention (N = 63) and control groups (N = 47). A short nutrition education on feeding and positioning skills was provided to caregivers and occupational therapy sessions to CP children. Bivariate and multivariable logistic regression analyses of collected data were done. Statistical significance was assessed at p < .05.

FINDINGS

The intervention significantly improved feeding skills of caregiver in the select indicators assessed. More caregivers appropriately positioned the children (AOR = 5.29; 95% CI: 2.00-13.96), fed children slowly (AOR: 5.17, 95% CI: 1.99-13.44), and involved the child during the feeding process (AOR = 3.46; 95% CI: 1.42-8.44). During feeding, caregiver's reported being less stressed (AOR = 2.53, 95% CI: 1.04-6.13) and the child's mood was more likely to be reported as improved (AOR = 3.15, 95% CI: 1.33-7.474). Although changes were observed in oral motor feeding skills (AOR = 1.67; 95% CI: 0.72-3.91) and functional feeding skills (AOR = 2.28; 95% CI: 0.86-6.06), they did not reach statistical significance in the multivariable models.

CONCLUSION

Strengthening nutrition education and services for caregivers of children with CP has great value in the care of children with special needs and may improve the health outcomes of children as well as reduce stress among parents/caregivers.

Characteristics of Dysphagia in Infants with Microcephaly Caused by Congenital Zika Virus Infection, Brazil, 2015

Oral motor dysfunction begins after 3 months of age and is severe.

We summarize the characteristics of dysphagia in 9 infants in Brazil with microcephaly caused by congenital Zika virus infection. The Schedule for Oral Motor Assessment, fiberoptic endoscopic evaluation of swallowing, and the videofluoroscopic swallowing study were used as noninstrumental and instrumental assessments. All infants had a degree of neurologic damage and showed abnormalities in the oral phase. Of the 9 infants, 8 lacked oral and upper respiratory tract sensitivity, leading to delays in initiation of the pharyngeal phase of swallowing. Those delays, combined with marked oral dysfunction, increased the risk for aspiration of food, particularly liquid foods. Dysphagia resulting from congenital Zika virus syndrome microcephaly can develop in infants >3 months of age and is severe.

European Society for Paediatric Gastroenterology, Hepatology and Nutrition Guidelines for the Evaluation and Treatment of Gastrointestinal and Nutritional Complications in Children With Neurological Impairment

OBJECTIVES

Feeding difficulties are frequent in children with neurological impairments and can be associated with undernutrition, growth failure, micronutrients deficiencies, osteopenia, and nutritional comorbidities. Gastrointestinal problems including gastroesophageal reflux disease, constipation, and dysphagia are also frequent in this population and affect quality of life and nutritional status. There is currently a lack of a systematic approach to the care of these patients. With this report, European Society of Gastroenterology, Hepatology and Nutrition aims to develop uniform guidelines for the management of the gastroenterological and nutritional problems in children with neurological impairment.

METHODS

Thirty-one clinical questions addressing the diagnosis, treatment, and prognosis of common gastrointestinal and nutritional problems in neurological impaired children were formulated. Questions aimed to assess the nutritional management including nutritional status, identifying undernutrition, monitoring nutritional status, and defining nutritional requirements; to classify gastrointestinal issues including oropharyngeal dysfunctions, motor and sensory function, gastroesophageal reflux disease, and constipation; to evaluate the indications for nutritional rehabilitation including enteral feeding and percutaneous gastrostomy/jejunostomy; to define indications for surgical interventions (eg, Nissen Fundoplication, esophagogastric disconnection); and finally to consider ethical issues related to digestive and nutritional problems in the severely neurologically impaired children. A systematic literature search was performed from 1980 to October 2015 using MEDLINE. The approach of the Grading of Recommendations Assessment, Development, and Evaluation was applied to evaluate the outcomes. During 2 consensus meetings, all recommendations were discussed and finalized. The group members voted on each recommendation using the nominal voting technique. Expert opinion was applied to support the recommendations where no randomized controlled trials were available.

Gastrointestinal and nutritional problems in neurologically impaired children

The current increasing survival of children with severe central nervous system damage has created a major challenge for medical care. Gastrointestinal and nutritional problems in neurologically impaired children have been recently recognized as an integral part of their disease, often leading to growth failure and worsened quality of life for both children and caregivers. Nutritional support is essential for the optimal care of these children. Undernourished handicapped children might not respond properly to intercurrent diseases and suffer unnecessarily. On the other hand, restoring a normal nutritional status results in a better quality of life in many. The easiest and least invasive method to increase energy intake is to improve oral intake. However, oral intake can be maintained as long as there is no risk of aspiration, the child is growing well and the time required to feed the child remains within acceptable limits. When oral intake is unsafe, insufficient or too time consuming, enteral nutrition should be initiated. Damage to the developing central nervous system may result in significant dysfunction in the gastrointestinal tract and is reflected in impairment in oral-motor function, rumination, gastro-oesophageal reflux (GER), with or without aspiration, delayed gastric emptying and constipation. These problems can all potentially contribute to feeding difficulty in disabled children, carrying further challenging long-term management issues.

A Virtual Environment to Improve the Detection of Oral-Facial Malfunction in Children with Cerebral Palsy

The importance of an early rehabilitation process in children with cerebral palsy (CP) is widely recognized. On the one hand, new and useful treatment tools such as rehabilitation systems based on interactive technologies have appeared for rehabilitation of gross motor movements. On the other hand, from the therapeutic point of view, performing rehabilitation exercises with the facial muscles can improve the swallowing process, the facial expression through the management of muscles in the face, and even the speech of children with cerebral palsy. However, it is difficult to find interactive games to improve the detection and evaluation of oral-facial musculature dysfunctions in children with CP. This paper describes a framework based on strategies developed for interactive serious games that is created both for typically developed children and children with disabilities. Four interactive games are the core of a Virtual Environment called SONRIE. This paper demonstrates the benefits of SONRIE to monitor children’s oral-facial difficulties. The next steps will focus on the validation of SONRIE to carry out the rehabilitation process of oral-facial musculature in children with cerebral palsy.

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.

Feeding children with cerebral palsy and swallowing difficulties

Children with cerebral palsy (CP) are at risk for aspiration with oral feeding with potential pulmonary consequences, and commonly have reduced nutrition/hydration status and prolonged stressful meal times. There is considerable variability in the nature and severity of swallowing problems in these children whose needs change over time. Children with generalized severe motor impairment (for example, spastic quadriplegia) are likely to experience greater swallowing deficits than those with diplegia, but oropharyngeal dysphagia is prevalent even in children with mild CP. This review is focused on dysphagia in children with CP: types of deficits, clinical and instrumental evaluation, management decision making and evidence of effectiveness of interventions.

Effects of oral motor therapy in children with cerebral palsy

AIM

Oral motor dysfunction is a common issue in children with cerebral palsy (CP). Drooling, difficulties with sucking, swallowing, and chewing are some of the problems often seen. In this study, we aimed to research the effect of oral motor therapy on pediatric CP patients with feeding problems.

MATERIALS AND METHODS

Included in this single centered, randomized, prospective study were 81 children aged 12-42 months who had been diagnosed with CP, had oral motor dysfunction and were observed at the Pediatric Neurology outpatient clinic of the Children's Health and Diseases Department, Istanbul Medical Faculty, Istanbul University. Patients were randomized into two groups: The training group and the control group. One patient from the training group dropped out of the study because of not participating regularly. Following initial evaluation of all patients by a blinded physiotherapist and pedagogue, patients in the training group participated in 1 h oral motor training sessions with a different physiotherapist once a week for 6 months. All patients kept on routine physiotherapy by their own physiotherapists. Oral motor assessment form, functional feeding assessment (FFA) subscale of the multidisciplinary feeding profile (MFP) and the Bayley scales of infant development (BSID-II) were used to evaluate oral motor function, swallowing, chewing, the gag reflex, the asymmetrical tonic neck reflex, tongue, jaw, and mouth function, severity of drooling, aspiration, choking, independent feeding and tolerated food texture during the initial examination and 6 months later.

RESULTS

When the initial and post-therapy FFA and BSID-II scores received by patients in the training and the study group were compared, the training group showed a statistically significant improvement (P < 0.05).

CONCLUSION

Oral motor therapy has a beneficial effect on feeding problems in children with CP.

A Pilot Study to Increase Chewing in Children With Feeding Disorders

Children with feeding disorders often display chewing deficits. Unfortunately, there is a paucity of research examining procedures to increase or teach chewing to children with feeding disorders. The few studies on this topic have utilized multicomponent treatments typically involving a shaping procedure. In addition, to our knowledge, studies on chewing have not yet incorporated a product measure of chewing (whether the food is broken down enough to swallow after chewing), which we have termed mastication. In the current investigation, we evaluated relatively simple treatments to increase chewing with two children with a feeding disorder who were not chewing at clinically acceptable levels after treatment with nonremoval of the spoon. We also developed a product measure of chewing. In Study 1, we used a least-to-most prompting plus praise procedure to increase chews per bite in a typically developing child with a feeding disorder. We then used the results of Study 1 to refine treatment and develop our mastication measure for Study 2. In Study 2, we implemented a descriptive verbal prompt and praise procedure to increase chews per bite and percentage of mastication with one child with developmental delays and a feeding disorder.

Clinimetrics of measures of oropharyngeal dysphagia for preschool children with cerebral palsy and neurodevelopmental disabilities: a systematic review

AIM

The aim of this study was to determine the psychometric properties and clinical utility of objective measures of oropharyngeal dysphagia (OPD) in children with cerebral palsy or neurodevelopmental disabilities aged 12 months to 5 years.

METHOD

Five electronic databases were searched to identify measures of OPD. The Consensus-based Standards for the Selection of Measurement Instruments (COSMIN) Checklist was used to assess psychometric properties and a Modified CanChild Outcome Rating Form was used for clinical utility.

RESULTS

Nine measures of OPD from 27 papers were assessed: the Brief Assessment of Motor Function - Oral Motor Deglutition Scale; the Behavioral Assessment Scale of Oral Functions in Feeding; the Dysphagia Disorders Survey; the Feeding Behaviour Scale; the Functional Feeding Assessment, modified; the Gisel Video Assessment; the Oral Motor Assessment Scale; the Pre-Speech Assessment Scale; and the Schedule for Oral Motor Assessment.

INTERPRETATION

The Schedule for Oral Motor Assessment and the Functional Feeding Assessment, modified, proved to be the strongest measures based on published psychometric properties of validity and reliability. The Schedule for Oral Motor Assessment and the Dysphagia Disorders Survey were found to have the strongest clinical utility. Further studies to test the psychometric properties of existing measures, in particular predictive validity, responsiveness, and test-retest reliability, would be beneficial for selecting an appropriate measure for both clinical and research contexts.

Feeding interventions for children with cerebral palsy: a review of the evidence

AIM

To examine the evidence of the effectiveness of different feeding interventions for children with cerebral palsy.

METHODS

A search of 12 electronic databases identified all relevant studies. For each study, the quality of the methods was assessed according to the study design. A total of 33 articles were retrieved, and 21 studies were included in the final analysis.

RESULTS

Feeding interventions were separated into five main categories: oral sensorimotor facilitation, food consistency, positioning, oral appliances, and adaptive equipment. Five studies were randomized controlled trials. Outcomes were mainly reported on feeding safety and efficiency. One study documented positive results in height and weight change. Nineteen of the 21 studies presented positive outcomes in eating efficiency and/or safety.

INTERPRETATION

Feeding interventions demonstrate potential benefits for children with cerebral palsy. However, the current level of evidence is poor, and empirical data are lacking. Methodologically, rigorous studies are required particularly investigating multimodal approaches.

Nutrition support for neurologically impaired children: a clinical report of the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition

Undernutrition, growth failure, overweight, micronutrient deficiencies, and osteopenia are nutritional comorbidities that affect the neurologically impaired child. Monitoring neurologically impaired children for nutritional comorbidities is an integral part of their care. Early involvement by a multidisciplinary team of physicians, nurses, dieticians, occupational and speech therapists, psychologists, and social workers is essential to prevent the adverse outcomes associated with feeding difficulties and poor nutritional status. Careful evaluation and monitoring of severely disabled children for nutritional problems are warranted because of the increased risk of nutrition-related morbidity and mortality.

Feeding method and health outcomes of children with cerebral palsy

Disorders of feeding and swallowing are common in children with cerebral palsy. Feeding and swallowing disorders have significant implications for development, growth and nutrition, respiratory health, gastrointestinal function, parent-child interaction, and overall family life. Assessments need to be comprehensive in scope and centered around the medical home. Oral feeding interventions for children with cerebral palsy may be effective in promoting oral motor function, but have not been shown to be effective in promoting feeding efficiency or weight gain. Feeding gastrostomy tubes are a reasonable alternative for children with severe feeding and swallowing problems who have had poor weight gain.

Feeding dysfunction is associated with poor growth and health status in children with cerebral palsy

OBJECTIVE

To describe parent-reported feeding dysfunction and its association with health and nutritional status in children with cerebral palsy.

DESIGN

Anthropometry was measured and z scores calculated. The Child Health Questionnaire was used to assess health status, and a categorical scale (none to severe) was used to classify subjects according to severity of feeding dysfunction.

SUBJECTS

230 children (9.7+/-4.6 years; 59% boys) with moderate to severe cerebral palsy were recruited from 6 centers in the United States and Canada.

STATISTICAL ANALYSES

Descriptive statistics, the Kruskal-Wallis and Pearson chi2 tests.

RESULTS

Severity of feeding dysfunction was strongly associated with indicators of poor health and nutritional status. The mean weight z scores were -1.7, -2.5, -3.3, and -1.8 among children with none, mild, moderate, or severe (largely tube-fed) feeding dysfunction, respectively (P= .003). Similar results were observed for height z score (P=.008), triceps z score (P=.03), and poor Global Health score (part of the Child Health Questionnaire) (P<.001). Subjects who were tube fed were taller (P=.014) and had greater body fat stores (triceps z score, P=.001) than orally fed subjects with similar motor impairment. For subjects exclusively fed by mouth, a dose-response relationship was observed between feeding dysfunction severity and poor nutritional status. Subjects with only mild feeding dysfunction had reduced triceps z score (-0.9) compared with those with no feeding problems (-0.3).

CONCLUSION

For children with moderate to severe cerebral palsy, feeding dysfunction is a common problem associated with poor health and nutritional status. Even children with only mild feeding dysfunction, requiring chopped or mashed foods, may be at risk for poor nutritional status. Parental report of feeding dysfunction with a structured questionnaire may be useful in screening children for nutritional risk.

Technical aspects of feeding the disabled child

Children with neurological impairment frequently have difficulties in consuming sufficient energy and other nutrients to maintain adequate nutritional status. Under-nutrition is a significant contributory factor to growth failure. Eating may be distressing and time-consuming for the child and carer. Aspiration of feeds is common and may predispose to chronic chest infections. Gastro-oesophageal reflux is also common and may contribute to significant morbidity. This paper discusses some of the issues involved in the nutritional management of neurologically impaired children.

Management of pediatric dysphagia

Decisions for management of feeding and swallowing problems in infants and children are likely to be most effective in a professional team approach with caregivers. Optimal management relies on optimal assessment. This article focuses on management strategies that involve "food rules," the position and posture changes, alterations in food and liquid attributes, oral-motor and swallow function, utensil changes, adjustments in feeding schedules and pacing, and behavioral intervention with failure to thrive in the context of global issues for children who are oral and nonoral feeders.
