the Efficacy of Oral Motor Therapy in Children With Autism

The First Affiliated Hospital of Anhui Medical University80 enrolled

Overview

Children with Autism spectrum disorders have speech disorders, which in turn aggravate communication difficulties and lead to an increase in their core symptoms. This experiment attempts to investigate the efficacy of Chinese language oral motor therapy in improving various aspects of articulation, language ability, and behavior of children with autism in conjunction with the International General Autism Scale, and provides a basis for the rational formulation of clinical treatment plans.

Oral Motor Therapy (OMT) is a treatment process that uses tactile and proprioceptive stimulation techniques to promote the normalization of the sensory perception of the mouth (jaw, lips, tongue), suppress abnormal mouth movement patterns, and establish normal mouth movement patterns, following the principles of motor skill development. This study investigates the efficacy of Chinese language oral motor therapy on improving various aspects of articulation, language ability, and behavior of children with autism. The study is divided into two parts, each eight weeks long. Eighty subjects who met the inclusion/exclusion criteria were randomly divided into 2 groups: the experimental group and the control group, in a 1:1 ratio. The experimental group was treated with 2 months of ABA+oral motor therapy followed by 2 months of ABA therapy; the control group was treated with 2 months of ABA therapy followed by 2 months of ABA+oral motor therapy. Each subject underwent ABC, CARS, S-S, VB-MAPP, and ABLLS-R assessments before enrollment, 2 months after enrollment, and after discharge from the group.

Interventions

oral motor therapyBEHAVIORAL

Rigorous Chinese language oral motor therapy, including treatment of oral perceptual disorders and treatment of oral motor disorders. The treatment follows three basic principles: a combination of basic training and specific treatment; a combination of self-help and assisted treatment; and a combination of exercises, cues, and stimulation techniques. 30-40 min/session, 1 session/day, 5 sessions/week.

ABABEHAVIORAL

The mainstream ASD intervention approach with evidence-based support is currently recognized worldwide. Treatment follows the operational core principles of ABA, which are to establish learning goals based on the child's ability level, design teaching situations and select reinforcers for them, change the child's behavior problems with operational constraints, and to eliminate or improve problem behaviors through appropriate interventions to shape new adaptive behaviors. The training time is at least 20 hours per week.

Outcomes

Primary Outcomes

Changes in the Verbal Behavior Milestones Assessment and Placement Program (VB-MAPP) scores

VB-MAPP is a criterion-referenced language and academic proficiency assessment system, curriculum instruction and skill tracking system for children with autism and speech and language delays. It is used for children 0-48 months of age. It has five components: milestone assessment, impairment assessment, transition assessment, task analysis, and supportive competencies and goals for placement and individualized education program (IEP).

Time frame: Baseline (week 0), Week 8，Week 16

Changes in Assessment of Basic Language and Learning Skills-Revised (ABLLS-R) scores

The ABLLS-R is for children ages 0-12. The scale has 25 major assessment items and 544 skill subtests that help children with autism learn the skills they need to communicate effectively and daily; and it can track the learning of each skill, which means that multiple assessments can be made, with the later assessment building on the previous one, giving this autism assessment tool a curriculum guide role.

Time frame: Baseline (week 0), Week 8，Week 16

Change in the Autism Behavior Scale (ABC) scores

The ABC scale is widely used in the assessment of autism conditions and the evaluation of treatment outcomes, and is one of the most commonly used autism assessment scales. It is used for screening of autistic individuals aged 18 months to 35 years. The scale is assessed by the child's parents or someone with whom the child has lived for at least 2 weeks and takes approximately 10-15 minutes to assess.

Time frame: Baseline (week 0), Week 8，Week 16

Change in Childhood Autism Rating Scale (CARS) scores

CARS is an observation tool used by clinicians for speech, behavior, and sensory perception in children with autism.

Time frame: Baseline (week 0), Week 8，Week 16
