Parameters characterizing the posture of preterm children in standing and sitting position

Abstract

BACKGROUND:

Systematic observations of fetal posture show that, although for most of the time the fetus does not have a preferred posture, it has a certain repertoire of repeated active postures. The observed postures cannot be considered random configurations of head and limb position: the fetus and the young infant have an active, but variable posture that is relatively unrelated to the orientation of the force of gravity.

MATERIALS AND METHOD:

The study included 101 children, aged 6–7, including 50 preterm children, 48 boys and 53 girls (research group) and 51 full-term children; 22 boys and 53 girls (control group). The photogrammetric method with moire effect on Mora 4G CQ Elektronik was used to examine the body posture.

RESULTS:

Significant statistical differences in GAMMA ( $p<$ 0.001) and KLL ( $p=$ 0.020) parameters in preterm children and in control group were noted. Both parameters presented higher value in the control group.

CONCLUSIONS:

The posture of preterm children is characterized by a smaller angle of upper thoracic curvature and smaller angle of lumbar lordosis. The posture of preterm children in sitting position is characterized by a smaller angle of thoracic kyphosis. Preterm birth disturbs the development of proper antigravitational mechanism and causes possible posture dysfunctions at the age of 6.
