“…Other authors have described LS postural changes when carrying backpacks with increasing load magnitudes in the 10-30% of body weight (BW) range. However, these data have been measured in a pediatric population using different loads, which may not be representative of military personnel and operational conditions (9,10).…”

The aim of the paper was to determine a correlation between the weight of a child's backpack, their body weight, and certain features of their body posture. Material and Methods. The study group consisted of 109 children, all aged seven years. The parameters of body posture were determined using the Zebris Ultrasonic System. Results. The number of children carrying a school backpack in accordance with recommendations was 44 subjects (40.37%). Statistically significant changes were found in the total length of the spine (Z = 2.223, p = 0.026) and between backpack weight and changes in the following parameters: the total length of the spine (r s = −0.3999, p = 0.017), the length and the angle of the lumbar lordosis (r s = −0.3352, p = 0.049), the angle of the lumbar lordosis (r s = −0.5065, p = 0.002), and the sacral angle (r s = −0.4279, p = 0.010). Conclusions. Wearing a backpack heavier than 10% of one's body weight can cause shallowing of the lumbar lordosis and a tendency towards a vertical position of the sacrum. Monitoring the weight of children's school backpacks and enabling them to leave books and notebooks at school would probably be beneficial in reducing the daily burden put on children's spines.

Objectives:This study aims to compare the extent of the spine curvatures in the sagittal plane during corrected sitting on a rehabilitation ball and during sitting on a chair without a backrest. Patients and methods:The study group consisted of 57 subjects (23 males, 34 females; mean age 24.7±2.3 years; range 20 to 32 years). The Moiré method was used to assess the body posture. The tests were conducted using the apparatus for computer assessment of the body posture MORA 4 Generation. The spine curvature was assessed in two positions: on a chair without a backrest and on a rehabilitation ball.Results: There was a statistically significant difference between the depth of thoracic kyphosis in both positions (p=0.003). A greater depth of thoracic kyphosis was recorded in the sitting position on a chair (4.3±5.3°) than in the sitting position on a rehabilitation ball (0.3±7.0°). A statistically significant difference was observed between the values of GAMMA in two consecutive measurements (p=0.049). Higher values of this parameter were noted in the sitting position on a rehabilitation ball (33.8±22.6°) versus on a chair (26.5±22.8°). Conclusion:Sitting on a rehabilitation ball as a corrective and therapeutic exercise should be preceded by teaching the patient how to adopt the correct position. Then, rehabilitation balls can become an alternative to chairs. Bulgular:Her iki pozisyonda da torakstaki kifoz derinliği arasında istatistiksel olarak anlamlı bir fark vardı (p=0.003). Rehabilitasyon topunda oturma pozisyonuna (0.3±7.0°) kıyasla, sandalyede oturma pozisyonunda (4.3±5.3°) daha yüksek toraks kifoz derinliği kaydedildi. İki ardışık ölçümde GAMMA değerleri arasında istatistiksel açıdan anlamlı bir fark gözlendi (p=0.049). Bu parametrede sandalyeye kıyasla (26.5±22.8°), rehabilitasyon topunda oturma pozisyonunda (33.8±22.6°) daha yüksek değerler kaydedildi.Sonuç: Düzeltici ve terapötik egzersiz olarak rehabilitasyon topuna oturma, hastanın doğru pozisyonu alacak şekilde öğretilmesi ile gerçekleştirilmelidir. Ardından, rehabilitasyon topları sandalyelere bir alternatif olabilir.
