Prevalence of orofacial dysfunction in cerebral palsy and its association with gross motor function and manual ability

Multisystem compensations and consequences in spastic quadriplegic cerebral palsy children

Spastic quadriplegic cerebral palsy (CP) is a permanent neuromuscular disorder causing limitation on all four limbs following a lesion on the developing brain. Most children with spastic quadriplegic CP are identified to be Gross Motor Function Classification System (GMFCS) level V, thus they have more comorbidities compared to other types at lower levels. Spastic quadriplegic CP is characterized by weak and inactive postural muscles of the neck and trunk, hence, they will undergo a total body extension as a compensatory mechanism leading to an atypical movement pattern, that give rise to multisystem consequences that reduce their quality of life. The relationship between atypical movement patterns, compensatory strategies, and multisystem consequences have not yet been explored. In fact, these multisystem consequences aggravate their condition and make movement much more atypical, forming a vicious cycle. This review aimed to provide a summary and highlight the mechanism of atypical movement pattern, multisystem compensations, and consequences in spastic quadriplegic CP children. It is true that central nervous system (CNS) lesion in CP is non-progressive, however the multisystem consequences may impair overall function over time. An understanding of how compensatory strategy and multisystem consequences in spastic quadriplegic CP offers the opportunity to intervene as early as possible to improve their quality of life.

Reliability and validity of the Dutch-language version of the Viking Speech Scale in children with cerebral palsy

PURPOSE

The Viking Speech Scale is used to classify speech performance in children with cerebral palsy (CP). A Dutch-language version (VSS-NL) has recently become available. This study aimed to determine the reliability and validity of the VSS-NL and the association with motor type of CP, Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS) and Communication Function Classification System (CFCS).

METHODS

A total of 90 children with CP, recruited throughout the Netherlands, took part in the study. VSS-NL classifications by speech and language therapists unfamiliar (SLT1) and familiar (SLT2) with the child, parents and physicians were compared. Convergent and discriminant validity were determined with the Intelligibility in Context Scale-Dutch (ICS-NL) and the Computer Based Instrument for Low Motor Language Testing (C-BiLLT). Inter- and intrarater reliability were determined by weighted Kappa (ƙ_w ). Validity and associations between VSS-NL and GMFCS, MACS and CFCS were determined with Spearman's coefficient. Association between VSS-NL and motor type of CP was determined with Fisher's exact test.

RESULTS

Interrater reliability was excellent between SLT1-SLT2 (ƙ_w  = 0.93, 95% confidence interval [CI] 0.87-0.99), good between SLT1-parent (ƙ_w  = 0.71, 95% CI 0.60-0.83), SLT1-physician (ƙ_w  = 0.70, 95% CI 0.58-0.81), SLT2-parent (ƙ_w  = 0.71, 95% CI 0.57-0.84), SLT2-physician (ƙ_w  = 0.73, 95% CI 0.62-0.85) and parent-physician (ƙ = 0.72, 95% CI 0.60-0.85). Intrarater reliability was excellent for SLTs familiar and unfamiliar to the child (ƙ_w  = 1.00, 95% CI 1.00-1.00), and very good for physicians (ƙ_w  = 0.89, 95% CI 0.75-1.00) and parents (ƙ_w  = 0.72, 95% CI 0.62-1.00). Convergent validity was very strong (r = -0.81, p < 0.001) and discriminant validity moderate (r = -0.56, p < 0.001). Association with motor type of CP was significant (χ²  = 27.558, p < 0.001) and strong with GMFCS (r = 0.62, p < 0.001), MACS (r = 0.63, p < 0.01) and CFCS (r = 0.69, p < 0.001).

CONCLUSION

The VSS-NL is a reliable and valid system to classify speech performance in children with cerebral palsy. Classifications can be performed by SLTs, parents and physicians.

Bruxism in children and adolescents with cerebral palsy

This study aims to summarize the existing evidence from primary studies in order to answer the following question: "are children and adolescents with cerebral palsy (CP) frequently affected by bruxism?". For such, databases Web of Science, Medline (via PubMed), Lilacs, SciELO, Scopus and Wiley Online Library were used, with the keywords “Cerebral Palsy” and “Bruxism” alone and in combination, without the restriction of the publication date. The search included all articles published until May 2020. A total of 229 publications were found, of which 12 were selected, after careful analysis. Retrospective data analyses, cross-sectional studies and observational case-control studies published in English and with samples composed of children and/or adolescents were included. Case reports, literature reviews and studies whose sample consisted of adults-only were excluded. In the evaluated studies, bruxism was present in all samples with cerebral palsy. However, oral signs and symptoms resulting from this parafunction were reported only in three studies, in which the presence of dental wear and pain was evaluated. Therefore, bruxism in children and adolescents with cerebral palsy is a frequent oral condition, however, knowledge about the associated and risk factors for the occurrence of this problem in these patients remains limited.

Orofacial functions and oral health: An analysis on children aged 5-8 years old

The aim of this study is to assess the orofacial function performance and oral health status of healthy children as well as their potential correlations. In this descriptive study, the oral functions of four hundred systemically healthy children who applied for the pediatric dentistry clinic were evaluated. Three scales, namely Karaduman Chewing Performance Scale (KCPS), Pediatric version of the Eating Assessment Tool (PEDI-EAT-10), and Nordic Orofacial Test Screening (NOT-S) protocol, are used to collect the data. These children's carious lesions were evaluated by using the decayed, missing, filled tooth/surface (DMFT/S, dmft/s) indices, the International Caries Detection and the Assessment-II System (ICDAS-II). In total, 400 (6.5 years [78.02 months]) children were participated in the study. Their KCPS scores indicate that 58.0% of the children were at level 0 and 35.8% were at level 1. The results of the KCPS levels and the DMFT, dmft, DT, dt, MT, mt (as =0 and ≥1) were found to be statistically significant; p = .044, p = .009, p = .008, p = .000, p = .032, and p = .003, respectively. The total PEDI-EAT-10 score of 13.4% of the children was found to be 3 or higher, suggesting that they experience a problem in swallowing. According to the NOT-S, the most affected domains were "habits" (51.0%), "facial expression" (49.3%), and "chewing and swallowing" (45.3%). Among healthy children without a defined problem in swallowing and orofacial functions, the oral health status may affect orofacial functions. Decayed (particularly, extensive caries existence) or missing tooth may have critical importance for adequate chewing in children. Especially in the presence of so many decayed or missing teeth, evaluating the orofacial functions through different scales may considerably contribute to early diagnosis of functional problems.

Oromotor dysfunction in minimally verbal children with cerebral palsy: characteristics and associated factors

AIM

To explore the characteristics and associated factors of oromotor dysfunction in minimally verbal children with cerebral palsy (CP) aged five to six years, recruited from a population-based registry. Methods: Twenty children with CP who were minimally verbal completed a standardised, observational oromotor assessment. Linear regression analyses examined the relationship between oromotor dysfunction and potential associated factors (e.g., fine and gross motor function, communication, and feeding). Results: Oromotor dysfunction affected every participant and was identified in all structures examined (i.e., face, jaw, lips, and tongue). Oromotor movements showed little dissociation among jaw, lip, and tongue movements. Oromotor dysfunction was univariately associated with the Manual Ability Classification System levels IV-V (p = 0.001), reduced communication skills (p = 0.002), and a prolonged eating duration (>45 min) (p = 0.006), even when non-verbal cognition served as a covariate. Interpretation: Oromotor dysfunction was highly prevalent in our sample of minimally verbal children with CP, having significant functional impacts on feeding and communication. Findings suggest that fine motor function (i.e., Manual Ability Classification System levels IV-V) is a stronger predictor than gross motor function for identifying children with CP who are minimally verbal and at risk of oromotor dysfunction.IMPLICATIONS FOR REHABILITATIONOromotor dysfunction was highly prevalent in our sample of minimally verbal children with cerebral palsy.Severe fine motor impairment strongly predicted oromotor dysfunction, indicating that fine motor function may provide an early indicator of impaired oromotor function for this clinical population.Robust, standardised measures of motor speech-related oromotor development suitable for children with cerebral palsy who are minimally verbal are lacking.Until such a measure is developed, formal evaluation may be achieved via oral motor assessments standardised for typically developing children, with the caveat one must interpret the results with caution.

Facial expression recognition for monitoring neurological disorders based on convolutional neural network

Facial expressions are a significant part of non-verbal communication. Recognizing facial expressions of people with neurological disorders is essential because these people may have lost a significant amount of their verbal communication ability. Such an assessment requires time consuming examination involving medical personnel, which can be quite challenging and expensive. Automated facial expression recognition systems that are low-cost and noninvasive can help experts detect neurological disorders. In this study, an automated facial expression recognition system is developed using a novel deep learning approach. The architecture consists of four-stage networks. The first, second and third networks segment the facial components which are essential for facial expression recognition. Owing to the three networks, an iconize facial image is obtained. The fourth network classifies facial expressions using raw facial images and iconize facial images. This four-stage method combines holistic facial information with local part-based features to achieve more robust facial expression recognition. Preliminary experimental results achieved 94.44% accuracy for facial expression recognition on RaFD database. The proposed system produced 5% improvement than the facial expression recognition system by using raw images. This study presents a quantitative, objective and non-invasive facial expression recognition system to help in the monitoring and diagnosis of neurological disorders influencing facial expressions.

Prevalence of drooling, swallowing, and feeding problems in cerebral palsy across the lifespan: a systematic review and meta-analyses

AIM

To determine the prevalence of drooling, swallowing, and feeding problems in persons with cerebral palsy (CP) across the lifespan.

METHOD

A systematic review was conducted using five different databases (AMED, CINAHL, Embase, MEDLINE, and PubMed). The selection process was completed by two independent researchers and the methodological quality of included studies was assessed using the STROBE and AXIS guidelines. Meta-analyses were conducted to determine pooled prevalence estimates of drooling, swallowing, and feeding problems with stratified group analyses by type of assessment and Gross Motor Function Classification System level.

RESULTS

A total of 42 studies were included. Substantial variations in selected outcome measures and variables were observed, and data on adults were limited. Pooled prevalence estimates determined by meta-analyses were as high as 44.0% (95% confidence interval [CI] 35.6-52.7) for drooling, 50.4% (95% CI 36.0-64.8) for swallowing problems, and 53.5% (95% CI 40.7-65.9) for feeding problems. Group analyses for type of assessments were non-significant; however, more severely impaired functioning in CP was associated with concomitant problems of increased drooling, swallowing, and feeding.

INTERPRETATION

Drooling, swallowing, and feeding problems are very common in people with CP. Consequently, they experience increased risks of malnutrition and dehydration, aspiration pneumonia, and poor quality of life.

WHAT THIS PAPER ADDS

Drooling, swallowing, and feeding problems are very common in persons with cerebral palsy (CP). The prevalence of drooling, swallowing, and feeding problems is 44.0%, 50.4%, and 53.5% respectively. There are limited data on the prevalence of drooling, swallowing, and feeding problems in adults. Higher Gross Motor Function Classification System levels are associated with higher prevalence of drooling, swallowing, and feeding problems. There is increased risk for malnutrition, dehydration, aspiration pneumonia, and poor quality of life in CP.

Assessment of orofacial dysfunction using the NOT-S method in a group of Turkish children with cerebral palsy

OBJECTIVES

A healthy determination of orofacial findings of children with cerebral palsy is important as this will lead us to utilize perfect multidisciplinary therapies of orofacial dysfunctions (OFD). Nordic Orofacial Test-Screening (NOT-S) is a comprehensive screening method of OFD which consists of a structured interview and clinical examination. The aim of our study was to evaluate the orofacial dysfunctions in a group of Turkish children with cerebral palsy using Nordic Orofacial Test-Screening (NOT-S) and find out the factors associated with OFD comparatively with a healthy group.

MATERIALS AND METHODS

NOT-S was applied to 84 children aged 3-16 years. Forty-two children with cerebral palsy were included in the study group and 42 healthy children were randomly selected for the control group. Two trained and calibrated examiners who were experienced on NOT-S interview and examination of the validity and reliability of the Turkish version performed screening and interpreted the results.

RESULTS

NOT-S interview and clinical examination subscale scores of children with cerebral palsy were higher and found to be statistically significant (Mann-Whitney U test; p < 0.001). The total scale score of the cerebral palsy group was also statistically significant (p < 0.001). The most common dysfunctions were in the facial expression area (55.9%) and in the chewing and swallowing area (52.4%) following in sensory function area (47.6%).

CONCLUSIONS

The results of this study indicated that the NOT-S protocol was an effective and valuable tool for the comprehensive screening of orofacial dysfunctions in a group of Turkish children with cerebral palsy.

Validity and reliability of the Persian version of the Eating and Drinking Ability Classification System

Background/Aims

The ability to eat and drink is the most important factor in health, survival and longevity. Children with cerebral palsy can suffer from severe dysphagia, which can lead to a high risk of aspiration and choking. As classifying eating and drinking ability in children with cerebral palsy is important in research and treatment, the aim of this study was to determine the cross-cultural validation and reliability of the Persian version of the Eating and Drinking Ability Classification System.

Methods

After translation procedures, the face validity, content validity, test–retest reliability and interrater reliability of the Eating and Drinking Ability Classification System were evaluated. In total, 130 parents of children with cerebral palsy and 34 therapists participated in the evaluation of the scale's reliability. The 73 boys and 57 girls with cerebral palsy were aged 3–20 years (mean age 4.4 years) and had various types of cerebral palsy. They were classified according to the Eating and Drinking Ability Classification System by both their parents and the therapists.

Results

The overall results indicated that the words and sentences used were simple, clear, understandable, relevant and necessary. The intraclass correlation coefficients for test–retest reliability for parents, occupational therapists and speech therapists were 0.98, 0.98 and 0.995, respectively. The interrater reliability between parents and occupational therapists was 0.96, between parents and speech therapists was 0.95, and between occupational therapists and speech therapists was 0.985.

Conclusions

The Persian version of the Eating and Drinking Ability Classification System seems to be valid and reliable. This system may be used to evaluate children with cerebral palsy.

Orofacial Dysfunction In Cleft And Non-Cleft Patients Using Nordic Orofacial Test - A Screening Study

Cleft lip, alveolus and palate is a congenital malformation caused by the lack of fusion of the lip and palate embryonic processes, which may disrupt the main functions of the stomatognathic system. Aim: This study aimed to assess the orofacial dysfunction in individuals with cleft lip, alveolus, and palate compared to non-cleft patients. One hundred and twenty individuals between 32 and 65 years of age were selected in the Craniofacial Center and in the School of Dentistry and divided into two groups: non-cleft patients (N-CLAP) and cleft lip, alveolus, and palate patients (CLAP). The two groups were matched by gender. Each individual was interviewed and submitted to a clinical evaluation during which the NOT-S was used to assess orofacial dysfunction. To verify the intra-examiner agreement, the values were compared using the Kappa test. The Mann-Whitney test compared performance on the NOT-S between the groups. The Chi-Square test compared the NOT-S domains between the groups. A comparison of the NOT-S scores between the groups revealed statistically significant differences in gender (p<0.001), but no statistically significant differences in the intragroup gender comparison were found. The assessment of the NOT-S domains between the N-CLAP and CLAP groups exhibited statistically significant differences in domains: breathing (p=0.021), chewing and swallowing (p<0.001), and dryness of the mouth (p=0.002) of the interview and significant differences in all domains of the clinical examination (p<0.001). Individuals with CLAP showed more orofacial dysfunction than non-cleft patients, without gender differences, after being assessed through the NOT-S.

Caries experience and oral health-related quality of life (OHRQoL) of children and adolescents with cerebral palsy in a low-resource setting

Background

Children with complex neurodevelopmental disabilities such as cerebral palsy (CP), have a higher risk of dental disease related at least in part to greater difficulties in performing and maintaining effective oral hygiene and oral care practices. However, to date, there are very few studies that have considered the impact of dental disease on the Oral Health-Related Quality of Life (OHRQoL) of children and adolescents with cerebral palsy. This study aimed to investigate the association between dental caries experience and oral health related quality of life (OHRQoL) among children and adolescents with cerebral palsy in a low-resource setting (Bangladesh).

Methods

A total of 90 children and adolescents with CP, 2–17 years old (median age 10 years; 37.8% female and 62.2% male) were randomly selected from the Bangladesh Cerebral Palsy Register (BCPR) The decayed, missing and filled teeth (dmft/DMFT) index was used to measure caries experience. Child Perceptions Questionnaire (CPQ) and Family Impact Scale (FIS) were used to assess oral health–related quality of life (OHRQoL). Binary logistic regression was used to investigate factors that may contribute to dental caries experience.

Results

Dental caries were observed among 55.6% of the participants. After adjusting for age and gender, binary logistic regression analysis showed that dental caries experience was significantly associated with those who had teeth/mouth pain (rate ratio 7.3; P = 0.02), food caught between teeth (rate ratio: 6.4; P = 0.02), difficulty in eating and drinking (rate ratio 5.9; p = 0.02) and those who felt frequently upset (rate ratio: 54.7; P = 0.02).

Conclusion

In this study, we found that children and adolescents with CP in a low-resource setting had high dental caries experience and that dental caries had a negative impact on OHRQoL amongst these participants and their parents/caregivers. Health care professionals should be aware of the importance of dental health and oral hygiene in this population. These findings highlight the need for oral health promotion programs for children and adolescents with CP in these settings to reduce pain and to improve quality of life.

The Eating and Drinking Ability Classification System for cerebral palsy: A study of reliability and stability over time

AIM

This study evaluated the inter-observer reliability and stability over time of the Eating and Drinking Ability Classification System (EDACS) for children and young people with cerebral palsy (CP).

METHOD

Case records for 97 children with CP were examined to collect retrospective data about eating and drinking abilities at four time-points with a minimum of 2 years between each time-point. Sex, Gross Motor Function Classification System (GMFCS) level, presence of feeding tube and orthopaedic issues were recorded from case records. One speech and language therapist (SaLT1) classified eating and drinking ability using EDACS for all cases at all time-points; SaLT2 assigned EDACS levels for 50 cases at time-point 1; SaLT3 assigned EDACS levels for 24 cases at all time-points. Inter-observer reliability and stability over time were assessed using the Intraclass Correlation Coefficient (ICC). Associations between EDACS levels and functioning recorded with other Functional Classification Systems (FCSs) were calculated using Kendall's tau (τ).

RESULTS

Out of 97 children, 48 were male, 48 had feeding tubes, and 83 had orthopaedic issues. ICC for EDACS levels recorded by SaLT1 across all time-points was 0.97 (95% CI 0.96-0.98); changes in EDACS levels occurred infrequently and never by more than one level. ICC between SaLT1 and SaLT2 at time-point 1 was 0.8 (95% CI 0.67-0.89); ICC between SaLT1 and SaLT3 across all time-points was 0.95 (95% CI 0.92-0.98). Association between GMFCS and EDACS was moderate (τ= 0.58).

INTERPRETATION

Retrospective use of EDACS to classify children's eating and drinking abilities appears reliable; EDACS appeared stable over 6 or more years in 86% of the cases.

Oropharyngeal Dysphagia in Adults With Dyskinetic Cerebral Palsy and Cervical Dystonia: A Preliminary Study

OBJECTIVES

To investigate the characteristics of oropharyngeal dysphagia in adults with dyskinetic cerebral palsy (DCP) and cervical dystonia (CD).

DESIGN

Exploratory observational cross-sectional study.

SETTING

University hospital.

PARTICIPANTS

Seventeen patients with DCP (8 men, 9 women; age, 45.7±6.3y) enrolled in a randomized controlled trial on the effects of botulinum toxin injection on CD.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Baseline clinical assessments and videofluoroscopic swallowing studies (VFSSs) were conducted. VFSS findings were evaluated using the videofluoroscopic dysphagia scale (VDS) and the penetration-aspiration scale (PAS). The Gross Motor Function Classification System (GMFCS) and Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) scores were also assessed. Relationships between outcomes were evaluated using Spearman's rank correlation.

RESULTS

The clinical assessment revealed abnormalities in chewing (n=10, 58.8%), tongue movement (n=10, 58.8%), and laryngeal elevation (n=8, 47.1%). The most common abnormality on the VDS was inadequate mastication (n=13, 76.5%), followed by premature bolus loss, vallecular residue, and penetration/aspiration (all: n=10, 58.8%). A maximum PAS score of 8 was observed in 8 of 17 patients (47.1%). Total and pharyngeal VDS scores were significantly correlated with TWSTRS scores (ρ=0.543, P=.024 and ρ=0.539, P=.026, respectively); the VDS oral score did not correlate with the TWSTRS score (ρ=0.446, P=.073). There was no significant correlation between VDS score and GMFCS level (ρ=0.212, P=.414).

CONCLUSIONS

This preliminary observational study presents the characteristics of oropharyngeal dysphagia in adults with DCP and CD. Pharyngeal stage difficulties were negatively correlated with severity of CD, but not with GMFCS level. Screening for dysphagia may be recommended in adults with DCP and severe CD.

"Everyone sees you sitting there struggling with your food": experiences of adolescents and young adults with cerebral palsy

Objective: The impact of difficulties with eating and drinking in adolescents and young adults with cerebral palsy is unknown. The purpose of this study is to find out which difficulties adolescents and young adults with cerebral palsy experience with eating and drinking in daily life and how they deal with these difficulties. The study also explores how they think about themselves with respect to eating and what does or does not help regarding social participation. Method: We collected the data from ten participants with spastic cerebral palsy (aged 15-23 years) living in the Netherlands. We used a qualitative study design with a conventional content analysis. Semi-structured in-depth interviews were used to identify meaningful factors related to eating and drinking difficulties. We coded relevant phrases from each interview and clustered and synthesized them into categories. Result: We derived four categories from the transcripts: (I) perceived eating and drinking difficulties (e.g., not managing to eat all food textures and/or choking); (II) challenges in physical and social context (e.g., accessibility of restaurants, menu supply, and/or needing assistance or not); (III) dealing with eating and drinking difficulties (e.g., adaptation, food avoidance, and/or giving up); (IV) Negative feelings about their eating and drinking (e.g., shame, frustration, fear for choking, and/or concerns about the future). One striking finding was that most participants had not recently received either monitoring or intervention for their feeding skills. Conclusion: This study shows that adolescents and young adults with cerebral palsy experience many restrictions in eating and drinking situations leading to negative feelings and lower participation levels, while little attention is directed towards these difficulties. Regular multidisciplinary rehabilitation programs should include evaluation, advice, and intervention regarding eating and drinking ability in order to increase social participation and self-management. Implications for Rehabilitation Adolescents and young adults with cerebral palsy experience difficulties with eating, drinking, and swallowing, and they encounter difficulties in participating in mealtimes with family and friends. Although adolescents and young adults with cerebral palsy rated their eating and drinking abilities as reasonable, they reported feelings of shame, frustration, fear, distress, and concerns for the future or unknown environments. Regular multidisciplinary involvement with eating and drinking is needed for purposes of evaluation, advice, and intervention throughout the life course, adjusted to living conditions and the latest evidence. Adolescents and young adults with cerebral palsy showed limited initiative in asking for personal assistance in eating and drinking activities.

Spatial Characteristics of Jaw Movements During Chewing in Children with Cerebral Palsy: A Pilot Study

This study compared jaw motion between children with cerebral palsy (CP) and their typically-developing (TD) peers during chewing. The jaw movements of 11 children with spastic CP (GMFCS levels II-V) all of whom were exclusively oral feeders with no reported clinical issues with feeding [mean age = 7.49 (2.30) years; 7 males, 4 females] and 11 age- and sex-matched TD peers [mean age = 7.54 (2.35) years] were recorded using optical motion capture. Participants chewed five trials of three different consistencies, including puree, mechanical soft, and solid. For each chewing sequence, the path distance (total amount of distance traveled by the jaw), average jaw speed, and working space (total 3-dimensional size of the jaw movements during chewing) were calculated. The CP group had greater path distances for mechanical soft and solids (p < 0.001) and larger working spaces (p < 0.001) than the TD group. Consistency differences were also found with path distances increasing for both groups with increased bolus consistency (p < 0.001). Puree was chewed most slowly for both groups (p = 0.05) and was associated with smaller working space than the other consistencies for both groups (p < 0.001). The TD group demonstrated slower speeds for mechanical soft as compared to solids (p = 0.05), a finding which was not observed in the CP group. The results suggest children with CP showed jaw movement differences during chewing despite being exclusive oral eaters with no reports of clinical feeding or deglutition disorders. Food consistency also influenced jaw movements in both children with CP and their TD peers.

Adverse drug reactions of botulinum neurotoxin type A in children with cerebral palsy: a pharmaco-epidemiological study in VigiBase

AIM

The aim of this study was to assess the risk of adverse drug reactions (ADRs) with botulinum neurotoxin type A (BoNT-A) in children with cerebral palsy (CP) using the World Health Organization global individual case safety report (ICSR) database, VigiBase.

METHOD

We extracted all children ICSRs for ADRs with BoNT-A used as anti-spastic drug in CP recorded between 1995 and 2015 in VigiBase. We also performed a case/non-case method (disproportionality analysis) to assess the link between exposure to BoNT-A and each ADR of interest in children and adults, calculating reporting odds ratios (RORs).

RESULTS

In VigiBase, 162 ICSRs were registered. They involved mainly males (n=95, 59%) and mean (SD) age was 7 years 11 months (4y 4mo). The most frequent ADR was dysphagia (27 ICSRs, 17%) followed by asthenia and muscular weakness (25 ICSRs each, 16%). Nineteen ICSRs (12%) were lethal. There was a significant association between BoNT-A and death in children (ROR=11.1 95%, confidence interval [CI] 7.0-17.7) but not in adults.

INTERPRETATION

In children with CP, most ADRs seem to be linked to a systemic spread of BoNT-A. Our study suggests a higher risk of ADRs with BoNT-A in children than in adults.

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.
