Oromotor skills in Autism

Based on review of research published between 1994 and 2022 on oromotor functioning in autistic individuals, 

key takeaways: 

• Oromotor functioning plays a foundational role in spoken communication and feeding.
• 81% of included 107 studies report a significant oromotor challenges related to speech production, nonspeech oromotor skills, or feeding 
• Studies used various methods to investigate oromotor functioning in autistics
• Behavioral measures -  tasks such as tongue protrusion, lip closure, and oral diadochokinesis. 
• Parent report measures - questionnaires and interviews. 
• Medical record review - examining medical records for information on feeding / swallowing difficulties. 
• Neuroimaging techniques -  fMRI & MEG.

• The findings suggest that oromotor challenges are common in autistics, but more research is needed to better understand the nature / extent and their impact on communication and feeding.

Some limitations of this paper include

• numerous inclusion and exclusion criteria, which may have excluded relevant studies eg: non-English publications, pre 1994 studies etc
• wide variation in studies re sample characteristics, behaviors analyzed, and research methodology, which makes it difficult to draw definitive conclusions. 
• did not include a meta-analysis, which would have allowed for a quantitative synthesis of the findings across studies.
