Scarf ratio: A method of measuring the Scarf sign in preterm born infants

Abstract: A new method of measuring the Scarf sign called the Scarf ratio is described in which data derived were reported on a continuous scale. The Scarf ratio is the distance of the olecranon process of the arm being tested as it moves across the trunk compared with the infant's own biacromial width. Longitudinal data for the Scarf ratio were measured in a cohort of 111 Thai preterm born infants. The data were collapsed into four age ranges ie 28-31, 32-36, 37-39 and 40 weeks post-conceptional age (PCA) according to … Show more

“…This finding is consistent with the results of Lekskulchai and Cole (2000b) for infants at the same age as our study sample. They found that preterm infants aged 28 to 31 weeks PCA recorded a lower scarf ratio than did infants who were older (32 to 40 weeks PCA).…”

“…O posicionamento das escápulas foi avaliado utilizando a medida em centímetros das bordas mediais superiores direita e esquerda, e das bordas mediais inferiores direita e esquerda até a coluna vertebral, inicialmente com a cabeça em rotação para direita e, posteriormente, com rotação para esquerda. 10 Por fim, para verificar a qualidade do tônus dos músculos do ombro e das escápulas, foi utilizado o sinal do cachecol 13 , observando a localização do olecrano em relação a linha média do tronco da criança. A avaliação do sinal do cachecol foi classificada em: cotovelo não alcança a linha média do tronco; cotovelo mantém-se na linha média do tronco; movimento amplo, cotovelo ultrapassa a linha média do tronco.…”

“…The scarf sign, which may be measured as the scarf ratio, has been used as a predictor of later motor performance (Lekskulchai & Cole, 2000a). The "scarf ratio is the distance of the elbow (olecranon process) of the arm being tested as it moves across the trunk compared with the infant's own biacromial width" (Lekskulchai & Cole, 2000b). Others note the scarf sign to be where the elbow is in relation to the infant's midline (nose) as the arm is gently nudged across the chest toward the posterior aspect of the opposite shoulder.…”
