Evaluation of a multicomponent intervention for diurnal bruxism in a young child with autism

Electromyography of diurnal bruxism during assessment and treatment

Diurnal bruxism among individuals with intellectual disabilities is often measured on the basis of its auditory products, thereby precluding the contingent presentation of stimuli during silent bruxism events. Electromyography (EMG) offers a technological solution to the identification of all bruxism events. EMG has not been previously evaluated in nonvocal clients with intellectual disabilities in the context of functional analysis and treatment. In the current series of analyses, we suggest a set of methods to implement EMG technology with this population. In Analysis 1, we propose a strategy for systematically identifying bruxism events. In Analysis 2 we evaluate an EMG staff-training package with naïve interventionists without past experience with EMG technology. Finally, Analysis 3 presents a practical example of this method during the functional analysis and treatment of a client with frequent diurnal bruxism.

Behavioral Treatment of Self-Injury: 2001 to 2016

Individuals diagnosed with intellectual and developmental disabilities (IDD) frequently exhibit self-injurious behavior (SIB). Previous research has examined the published literature on behavioral treatments of SIB from 1964-2000. Results suggested that these treatments were highly efficacious at decreasing SIB, particularly when based on the results of a functional assessment. The purpose of this review is to update, replicate, and extend the previous research. The current findings indicate an increase in studies reporting automatically maintained SIB as well as less efficacious treatments overall. Discussion of our conclusions and methods of SIB assessment and treatment are discussed, both as they relate to the previous review and for future directions.

Self-Injurious Behavior in Children With Developmental Disabilities: A Systematic Review of Behavioral Intervention Literature

We reviewed single-case research studies examining the effects of behavioral interventions for self-injurious behavior (SIB) in young children with autism and developmental disabilities. Systematic searches of electronic databases, journals, and reference lists identified 46 studies (66 participants younger than the age of 12) meeting inclusion criteria. Studies were examined based on (a) participant demographics, (b) topography and function of SIB, (c) type of functional behavior assessment (FBA), (d) intervention procedures and outcomes, and (e) experimental design and measurement. Intervention strategies were categorized as antecedent manipulations, teaching behavior, consequence-based procedures, and/or extinction procedures. Positive outcomes were reported for 78% of participants in the reviewed studies and 88% of the participants were diagnosed with autism. Results suggest the effectiveness of behavioral interventions to decrease SIB for young children with disabilities; however, the frequent use of packaged interventions without component analysis limits the conclusiveness of any treatment recommendation. Suggestions for future research are discussed.

Oral health among preschool children with autism spectrum disorders: A case-control study

AIM

To assess and compare the oral health status of preschool children with and without autism spectrum disorders.

METHODS

A random sample of 347 preschool children with autism spectrum disorder was recruited from 19 Special Child Care Centres in Hong Kong. An age- and gender-matched sample was recruited from mainstream preschools as the control group. Dental caries status, gingival health status, tooth wear, malocclusion, dental trauma and oral mucosal health were assessed and compared between the two groups.

RESULTS

It was feasible to conduct a comprehensive oral health screening among 74.1% (257) of the children with autism spectrum disorder. The mean age was 59 ± 10 months (range from 32 to 77 months), of whom 84.4% were males. Children with autism spectrum disorder had better gingival health than children without autism spectrum disorder (mean plaque score and gingival score p < 0.001). Children with autism spectrum disorder had less caries experiences than children without autism spectrum disorder (mean decayed, missing and filled surfaces and decayed surfaces, p < 0.05). Children with and without autism spectrum disorder had similar prevalence of tooth wear, malocclusion, dental trauma experience and oral mucosal lesions (p > 0.05).

CONCLUSION

Differences in oral health status exist among preschool children with and without autism spectrum disorder. Preschool children with autism spectrum disorder exhibited lower caries experiences and better gingival health than children without autism spectrum disorder.

Measuring oral sensitivity in clinical practice: a quick and reliable behavioural method

This article aims to offer a behavioural assessment strategy for oral sensitivity that can be readily applied in the clinical setting. Four children, ranging in age and with a variety of developmental and medical problems, were used as test cases for a task analysis of tolerance to touch probes in and around the mouth. In all cases, the assessment was sensitive to weekly measures of an intervention for oral sensitivity over a 3-week period. Employing an inexpensive, direct, specific to the individual, replicable, reliable, and effective measure for a specific sensory problem would fit better with the edicts of evidence-based practice. The current method offered the initial evidence towards this goal.
