Objective: To evaluate the pattern of developmental delay of language and to correlate the language with other developmental areas in cerebral palsy children.

Method: Sequenced Inventory of Communication Development (SICD) was studied in 31 children with cerebral palsy of age ranging from 11 months to 48 months. Korean Denver Developmental Screening Test (DDST) was also performed in 18 children simultaneously.

Results: On SICD, 10 children (32.3%) showed the receptive language delay and 13 children (41.9%) showed the expressive language delay. Among 15 spastic quadriplegic children, 40% showed the delay of receptive language development, 53.3% showed the delay in expressive language development. Among 10 spastic diplegic children, 30% showed the delay of both receptive and expressive language development. One spastic right hemiplegic child showed a delay of expressive language development, but 4 left hemiplegic children showed the normal language development. One hypotonic cerebral palsy child showed a delay of both receptive and expressive language development.

The expressive language was delayed more than the receptive language.

SICD correlated highly with the language sector of DDST. And both SICD and DDST language sectors correlated with the other sectors of DDST (personal-social, fine motor-adaptive, gross motor), especially with the fine motor sector (r=0.912, 0.918, 0.976, p＜0.001).

Conclusion: There is a considerably high incidence of developmental delay of language in cerebral palsy children, especially among spastic quadriplegic children.

The early evaluation and treatment for the developmental delay of language need to be included in a general rehabilitation program for the cerebral palsy children.
