Home-Based Action Observation Training for Chewing and Swallowing Function

The Effect of Home-Based Action Observation Training on Chewing and Swallowing Function in Children With Cerebral Palsy

This study is a two-part randomized controlled trial designed to investigate the effects of home-based Action Observation Training (AOT) combined with Functional Chewing Training (FuCT) in children with Cerebral Palsy (CP) who have chewing disorders.

In Part I, the primary outcome results-chewing function, swallowing function, and feeding behaviour-will be reported. In Part II, the secondary outcome results, including child participation, quality of life, and caregiver impact, will be presented.

Within the scope of the study, children with CP will be randomly allocated to either a study group or a control group. Both groups will receive FuCT (5 sets per day, 5 days per week, for 12 weeks). In addition, the study group will participate in a home-based AOT program delivered via telerehabilitation (1 set per day, 3 days per week, for 12 weeks) under the guidance of a physiotherapist.

All participants will be assessed at baseline, at week 6, and at the end of week 12.

Inclusion Criteria:

• Diagnosed with Cerebral Palsy,
• Age between 6 and 18,
• IQ level of 70 or above,
• Having complaints related to chewing function and inability to manage solid food intake
• Feeding orally.

Exclusion Criteria:

• Having a neurodegenerative disease other than Cerebral Palsy
• Having additional chronic illnesses such as systemic diseases, cancer, kidney diseases, gastrointestinal system diseases, etc., that may affect nutritional status,
• Experiencing visual or hearing impairment,
• Using any medication and/or oral device that may affect chewing performance,
• Having received previous chewing and/or swallowing training.
