Use of consensus methods to determine the early clinical signs of cerebral palsy

To develop expert-informed content regarding the early motor attributes of cerebral palsy (CP) that should prompt physician referral for diagnostic assessment of CP, as well as concurrent referral recommendations. This content will be used in the creation of knowledge translation (KT) tools for primary care practitioners and parents.

Two nominal group processes were conducted with relevant stakeholders, representing Canadian 'content experts' and 'knowledge-users', using an integrated KT approach.

Six attributes were identified that should prompt referral for diagnosis. If the child demonstrates: Early handedness <12 months; stiffness or tightness in the legs between 6 and 12 months; persistent fisting of the hands >4 months; persistent head-lag >4 months; inability to sit without support >9 months; any asymmetry in posture or movement. Five referral recommendations were agreed upon: Motor intervention specialist (physical therapy and/or occupational therapy) for ALL; speech-language pathology IF there is a communication delay; audiology IF there is parental or healthcare professional concern regarding a communication delay; functional vision specialist (e.g., optometrist or occupational therapist) IF there is a vision concern (e.g., not fixating, following, or tracking); feeding specialist (e.g., occupational therapist, speech-language pathologist) IF there are feeding difficulties (e.g., poor sucking, poor swallowing, choking, and/or not gaining weight).

Rigorous consensus methods provided the initial evidence necessary to inform the content of tools to assist primary care providers in the early detection of CP. Results will be validated through a Delphi process with international experts, and user-friendly formats of this KT tool will be developed collaboratively with stakeholders.
