Active self correction of child’s posture assessed with plurimeter and documented with digital photography
Journal Title: Postępy Nauk Medycznych - Year 2012, Vol 25, Issue 6
Abstract
<b>Introduction. </b>Body posture is the position in which a person holds the body upright in a spontaneous standing position. It is externally manifested by the mutual spatial alignment of body parts and by the person’s figure. The posture may be spontaneous, so-called habitual, or actively corrected by the child, referred to in the literature as “actively corrected”. The aim of the study was to evaluate the manner of posture correction by school children instructed with the “stand straight” command.<br><b>Material and methods.</b> 126 primary school pupils, 60 girls and 66 boys, aged 7.0 to 13.0 years (9.1 ± 1.6), were examined in standing position twice: in a relaxed posture and in actively corrected posture (after the “straight the back” command). Children were not instructed what corrected posture means. Sagittal clinical angles: C7-T12 (total thoracic kyphosis, TTK), C7-T6 (proximal thoracic kyphosis, PTK), T6-T12 (distal thoracic kyphosis, DTK), T12-S1 (lumbar lordosis, LL) and sacral inclination (SI) were measured with Rippstein plurimeter. The study included also a photographic documentation of the body to show visual changes of the movement. Significance of difference of the means was checked with paired t-test.<br><b>Results. </b>The TTK, PTK, DTK, LL and SI angles in relaxed versus corrected posture were as follows: 38.7° ± 9.0° versus 27.6° ± 10.5° (difference significant), 32.4° ± 5.3° versus 29.3° ± 6.8° (difference significant), 6.6° ± 7.8° versus -2.3° ± 8.2° (difference significant), 34.8° ± 8.0° versus 33.6° ± 8.3° (not significant) and 23.5° ± 5.9° versus 25.8° ± 5.5° (difference significant), respectively.<br><b>Conclusions. </b>Plurimeter measurement and digital photography documentation allowed for a qualitative and quantitative assessment of children’s posture and its changes following a verbal stimulus. Children reacted to the “stand straight” command by changing their posture, which meant creating a pathological lordosis in the lower thoracic spine. The “stand straight” command given to children in order to correct their posture should be preceded by appropriate instructions in order to avoid improper correction patterns.
