Speech Intervention for Children With Cleft Palate Using Principles of Motor Learning

Area of Science:

• Speech-Language Pathology
• Pediatric Health
• Motor Learning

Background:

• Children with cleft palate often experience speech and resonance disorders.
• Traditional speech therapy may not fully address complex speech errors associated with cleft palate.
• Principles of motor learning (PML) offer a framework for optimizing motor skill acquisition in speech.

Purpose of the Study:

• To investigate the effectiveness of an articulatory kinematic speech intervention applying PML for children with cleft palate.
• To assess improvements in phoneme production, generalization to untreated sounds, and treatment retention.
• To evaluate the impact on speech and resonance outcomes in this pediatric population.

Main Methods:

• A pilot study employing a multiple-baseline, single-case experimental design.
• Four children with cleft-type speech errors received twice-weekly, 8-week blocks of articulatory kinematic speech intervention.
• Treatment focused on active and inconsistent passive cleft speech errors, with outcomes measured by percentage of words correct and perceptual accuracy.

Main Results:

• The intervention led to significant improvements in treated phonemes for three children with active and inconsistent passive errors.
• Generalization of improved phoneme production to untreated items was observed.
• Inconsistent passive cleft speech errors showed particular responsiveness to the treatment.

Conclusions:

• Articulatory kinematic speech intervention incorporating PML is effective for improving speech outcomes in children with cleft palate.
• The findings support the validity of this approach for further research and clinical application.
• This intervention shows promise for addressing specific speech challenges in children with cleft palate.
