Cleft Palate Children Clinical Trial
Official title:
The Effect of Using Symbolic Gestures on the Speech and Language Development in Prelinguistic Children Born With Cleft Palate
Children born with a cleft lip and palate (CLP) are known to be at risk for speech-language disorders that impact academic and social emotional growth. Even at very young ages (<3 years), speech-language disorders are already observed. It is hypothesized that speech-language intervention delivered before the age of 3 years old could decrease the impact of CLP on speech-language development. This would result in a decreased need for speech-language therapy on the long-term and a reduced burden of care on children, families and health services. However, no evidence is yet available to support any specific model of early speech-language intervention in this population. Consequently, no standardized clinical practice guidelines are available yet. Symbolic gesture training in combination with verbal input expands the natural communication of young children including multimodal speech-language input (i.e., verbal and manual input) via caregivers who act as co-therapists. To contribute to the evidence-based practice in the field of cleft speech therapy, this research project aims to determine the effectiveness and feasibility of symbolic gesture training in one-year old children with CLP by comparing different intervention approaches based on perceptual, psychosocial and qualitative outcome measures.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Receptive language level based on language test | To verify the receptive language level, the Dutch Nonspeech Test will be used at T0 and T1. This standardized test observes, scores and judges communication conditions and first verbal and non-verbal communication in the age range of 12 to 21 months. At T2, the Schlichting Test of Language Comprehension and Language Production will be used. This standardized test measures receptive and expressive language development starting from 24 months of age.
This outcome measure will be expressed in percentiles. |

Primary | Expressive language level based on language test | To verify the expressive language level, the Dutch Nonspeech Test will be used at T0 and T1. This standardized test observes, scores and judges communication conditions and first verbal and non-verbal communication in the age range of 12 to 21 months. At T2, the Schlichting Test of Language Comprehension and Language Production will be used. This standardized test measures receptive and expressive language development starting from 24 months of age.
This outcome measure will be expressed in percentiles. |
12 months | |
Primary | Total language level based on caregiver report | Caregivers will complete the Dutch version of the MacArthur Communicative Development Inventory, 'words and signs' (T0 and T1) or 'words and sentences' (T2). These standardized questionnaires evaluate word comprehension and production, the use of signs by the child, and grammatical development.
This outcome measure will be expressed in percentiles. |
12 months | |
Secondary | Communicative acts produced by the child | The communicative acts of the child will be analyzed based on a video recording of 30 minutes free play with four standardized toy sets (i.e., a farm, a house, cutlery, and vehicles) between the child and caregiver at T0, T1 and T2. Each potential communicative act of the child will be annotated by the means of communication (eye contact, gesture or vocalization; vocalization will be identified as non-canonical, canonical or word).
This outcome measure will be expressed in the total number of communicative acts produced by the child. |

Each potential communicative act of the caregiver will be annotated by the means of communication (eye contact, gesture or vocalization).

Secondary | Articulatory precision of the child | Based on the vocalizations of the child, the Percentage Consonants Correct will be determined. This outcome measure is expressed in percentage. | 12 moths |
