Effect of different backpack loading from standing on ventilatory functions for primary school Egyptian children

Master Abstract

Effect of different backpack loading from standing on ventilatory functions for primary school Egyptian children, Eman Wagdy Mahmoud, Supervisors, Prof. Dr. Elham El Sayed Salem. Cairo University, Dr. Aly Saad Rafea. El Matarya Teaching Hospital, Faculty of Physical Therapy, Cairo University, 2011 (Master Degree) 118 pages. Abstract Background: The carriage of backpacks has been shown to constitute a considerable daily "occupational" load on the spines of school children. Heavy loading of the spine induces vertebral stress which subsequently leads to musculoskeletal problems such as scoliosis, kyphosis and lordosis in children during growth. Purpose: investigate the effect of shoulder girdle loading with different loads on ventilatory functions in primary school children. Methodology: Two hundred and fifty primary school children aged between 8 to 12 years underwent spirometry measurements while adopting the following four conditions: free standing, standing carrying a backpack weighing 10%, 20% and 30% of their body weight. Measures: Forced vital capacity (FVC) in liter, forced expiratory volume in the first second (FEVR1R) in liter, forced expiratory volume in the first second / Forced vital capacity ratio (FEVR1R/FVC %) and peak expiratory flow rate (PEFR) in liter/min. Results: There were statistically significant differences between the predicted and the actual mean±SD values in all measured parameters at all positions (p<0.001). Also, there were statistically significant differences between the actual mean±SD values in all measured parameters at all positions. Finally, a significant decrease was recorded when the actual mean±SD values compared for all measured parameters particularly when the load in the backpack was increase to 30% of body weight. Conclusion: This study demonstrates a restrictive effect on ventilatory functions when a school bag is heavier than 20% of a child’s body weight.

Anthropometric measurements in relation to trunk muscles endurance and spinal mobility in primary school children

PHD Abstract

Anthropometric measurements in relation to trunk muscles endurance and spinal mobility in primary school children/ Eman Wagdy Mahmoud, Supervisors: Prof. Dr. Elham El Sayed Salem, Prof. Dr. Eman Ibrahim El-Hadidy, Department of Physical Therapy for Growth and Development Disorder in Children and its Surgery, Faculty of Physical Therapy, Cairo University. Doctoral Thesis (2015). Abstract Background:Anthropometric variables influence the individual's stability and it makes sense that it would influence endurance. Data on anthropometric characteristics, trunk muscles endurance, and spinal mobility are the subject of many studies.Purpose: To compare trunk muscles endurance and spinal mobility values between boys and girls and; to determinethe correlation of the age and selected anthropometric measurements with trunk muscles endurance and spinal mobility in primary school children. Methodology: Three hundred out of three hundred and fifty school children with age from 7 to 12 years underwent anthropometric measurements included body weight (BW) in kg, body height (BH) in meter and body mass index (BMI) in Kg/m2 Keywords: Anthropometric measures, Trunk muscle endurance tests, Spinal ROM, Primary school children. ; trunk muscle endurance test/seconds(extensors & flexors)and spinal range of motion test/degrees(lumbar extension & flexion ROM). Results:The results revealedno significant difference in trunk(extensors & flexors) muscle endurance and lumbar flexion ROM values between boys and girls while significant difference in lumbar extension ROM values between them. Age and BH had positive correlation with trunk extensors muscle endurance and lumbar extension ROM for both sexes while negative correlation with other measures for both sexes. BW and BMI had negative correlation with trunk (extensors & flexors) muscle endurance and lumbar (extension & flexion) ROM for both sexes. Conclusion:This study demonstrated significant difference between boys and girls in lumbar extension ROM values while, no significant difference between them in other measures. According to the strength of the correlation; boys and girls had different relationships of the age and selected anthropometric measurements (BW, BH and BMI) with trunk muscle endurance values, and spinal mobility values.
