Translation to Brazilian Portuguese and Cultural Adaptation of the Craniocervical Dysfunction Index

Abstract

Introduction Functional disorders of the craniocervical region affect 77.78% of Brazilian teachers. Among the most common instruments used to assess craniocervical disorders in a detailed and objective way, none had been translated to Brazilian Portuguese and adapted to Brazilian culture. Objectives To translate to Brazilian Portuguese and to culturally adapt the Craniocervical Dysfunction Index (CDI). Method The first phase of the study consisted of the translation, synthesis, back-translation, and review of the contents by a committee of experts, who developed a trial version and sent all the steps to the original author. The trial version was applied to 50 teachers of an institution. The reliability and internal consistency were evaluated by Cronbach α. For the validation, the Brazilian Portuguese version of the CDI was correlated with the Visual Analogue Scale (VAS) domains for cervicalgia and evaluated by Spearman ρ. Result Some expressions were adapted to the Brazilian culture. Among the participants who did not report neck pain in the VAS, 84.21% suffered from craniocervical dysfunction acording to the CDI. Among the participants who reported neck pain in the VAS, 100% suffered from craniocervical dysfunction according to the CDI. The CDI showed good internal consistency and satisfactory reliability measured by Cronbrach α (α = 0.717). There was a strong correlation between the CDI and the VAS score (ρ = 0.735). Conclusion No difficulties were encountered in the translation and back-translation of the CDI, and no problems were observed regarding the trial version developed; therefore, the Brazilian Portuguese version of the CDI is a valid and reliable instrument to evaluate the functional alteration of the craniocervical region.

Impacto da dor cervical, da mobilidade e do índice de massa corporal no controle postural de professores

“…Em relação às avaliações das disfunções craniocervicais, são poucos os recursos existentes. Sendo assim, a validação do Craniocervical Dysfunction Index (CDI -versão brasileira) proporciona ao profissional da saúde a investigação detalhada e precoce de tal disfunção, avaliando a dor cervical, tensão muscular, sons articulares durante o movimento da coluna cervical, amplitude de movimento, dor durante o movimento e postura da região craniocervical 13 . Essas podem estar relacionadas a mudanças metabólicas, interferindo no IMC, ou estruturas funcionais, acarretando -instabilidade postural.…”

Impact of cervical pain, neck mobility, and body mass index on teachers’ postural control

“…Few resources are available to assess craniocervical disorders. Hence, the validation of the Craniocervical Dysfunction Index (CDI -Brazilian version) provides health professionals with a detailed and early investigation of such disorder, assessing cervical pain, muscle tension, and joint sounds during cervical spine movements, the amplitude of movement, pain during movement, and craniocervical posture 13 . They can be related to metabolic changes, interfering with BMI or functional structures, causing postural instability.…”
