What is the Effect of Loading in School Children?

Research Paper Title

Effect of backpack loading on cervical and sagittal shoulder posture in standing and after dynamic activity in school going children.

Background

Adolescent age group as school going children who experience a period of accelerated growth and development of skeletal and soft tissue.

Any daily physical stresses external forces such as load carrying may also influence alignment of the human body.

It is assumed that daily intermittent abnormal postural adaptations could result in pain and disability.

To know the effect of backpack loading on cervical and sagittal shoulder posture (SSP) in standing and after dynamic activity in school going children.

Methods

The research project was conducted after getting clearance from Human Research Ethics Committee of the H M Patel Institution for Education and research centre.

Study was conducted on 160 school going children, and measurement were taken to know the loading over the cervical region along with their bagpacks were weighed.

Results

Total 160 students were enrolled in the present study. Study found that average value of the subject’s body weight was 34.83 kg, and subjects backpack weight was 6.42 kg that was equivalent to 18% of the subject’s body weight.

The mean value of cranio-vertebral angle (CVA) without school bag was 40.62. The mean values of cranio-horizontal angle (CHA) while standing with 18% of body weight and after dynamic activities with 18% of body weight were 24.51 ± 10.3 and 28.93 ± 4.34, respectively.

The mean value of SSP without school bag was 39.39 ± 4.31, whereas the mean values of SSP while standing with 18% of body weight and after dynamic activities with 18% of body weight were 54.38 ± 21.19 and 77.62 ± 17.50, respectively.

Conclusions

This study revealed that there is a significant reduction in the CVA (or increased forward head position), increase in CHA, and SSP were found while carrying a backpack weight 18% of body weight over both shoulders.
