Postura crânio-cervical em mulheres disfônicas Craniocervical posture in dysphonic women
Abstract
OBJETIVO: Analisar a postura e a função da região crânio-cervical em sujeitos disfônicos. MÉTODOS: Participaram do estudo 28 mulheres (31,25±8,14 anos), divididas em dois grupos: experimental (N=16 portadoras de disfonia) e controle (N=12 clinicamente normais). As voluntárias foram submetidas à avaliação do Índice de Disfunção Crânio-Cervical (IDCC) e fotogrametria, sendo determinado o ângulo anterior formado entre a sétima vértebra cervical e o tragus, o qual corresponde à posição da cabeça no plano sagital. A análise das fotos foi realizada por três examinadores, duas vezes cada um, com intervalo de uma semana entre elas. A análise dos dados constou do teste de Shapiro-Wilk, seguido do teste t de Student, (pPurpose: To analyze the posture and the function of the craniocervical region in women with dysphonia. METHODS: Twenty eight women participated in the study (31.25±8.14 years), divided into two groups: experimental (N=16, patients with dyphonia) and control (N=12, clinically normal). The volunteers were submitted to evaluation of the Craniocervical Dysfunction Index (CDI) and photogrammetry, determining the anterior angle formed between the seventh cervical vertebra and the tragus, which corresponds to the head position in the sagittal plane. The analysis of the photos was carried out by three examiners, twice each, with an interval of one week between them. Data analysis used the Shapiro-Wilk test, followed by the Student's t-test, (p<0,05). RESULTS: No difference was found between the mean values of the anterior angle of the control (50.92±5.18 degrees) and the experimental (49.63±5.46 degrees) groups in the photogrammetry (p=0.2565). The CDI showed that the experimental group had craniocervical dysfunction, which was mild in 37.5% of the cases, moderate, in 37.5%, and severe in 25%. In the control group, 100% of the volunteers had presented mild craniocervical dysfunction. CONCLUSION: There was no difference between the evaluated groups regarding head position. However, dysphonic women presented more severe craniocervical dysfunction than the group control.
