Effects of the sitting position on the body posture of children aged 11 to 13 years

Abstract

Maintaining a sitting position for a long time results in advanced asymmetries of the trunk and scoliosis, and causes a decrease in lumbar lordosis and kyphosis of a child's entire spine. Therefore, we advocate the introduction of posture education programs for schoolchildren.

Prevalence of Lower Crossed Syndrome in School Going Children of Age 11 To 15 Years

“…This time reaches its peak in between 11 to 15 years. [7] Prolonged sitting causes hip flexor tightness which causes anterior pelvic tilt which promotes lumbar lordosis. This causes weakness of gluteal muscles and abdominal muscles.…”

“…[6] Nowadays, children spend more time in a seated position, both at school during class and at home in front of television. [7] Children become more sedentary with age & also accumulates their sedentary time in increasingly prolonged periods. [8] Objective data show that children aged 4-15 years are sedentary for an average 7-8 hours a day.…”

“…[8] Objective data show that children aged 4-15 years are sedentary for an average 7-8 hours a day. [7]Nursery schoolchildren were seated for 37.2% of their time in the classroom through to 78.7% for senior school pupils aged 13 to 16 years. [9]Children under 11 years averaged approximately 1.3 hours less daily sedentary time than those aged 11 to 14 years of age & roughly 2 hours less than those 15 to 19 years of age.…”

“…Weakening of the corresponding muscle occurs due to muscular inactivation over long period of time. [7] Children adopt different postures during classes regardless of postural variations created by ergonomically designed sitting arrangement. [12]Prevalence of low back pain did not reduced even if children preferred ergonomically designed furniture.…”

Concurrent validity of photogrammetric and inclinometric techniques based on assessment of anteroposterior spinal curvatures

“…This is necessary, regardless of the problem reported by a patient, since many factors may impact the shape of these curvatures [1][2][3], which should be taken into account in designing physiotherapy. Results of posture assessment largely depend on examiner's knowledge and experience, but they are also affected by the quality of diagnostic tools and measurement errors generated during such examination [4].…”
