Abstract

Background/Objectives

The purpose of the study is to compare and measure the longus colli and SCM, and craniovertebral angle when you carriage a backpack in standing position.

Methods/Statistical analysis

After preliminary research was performed, with five healthy female and 25 healthy male, total 30 people who were matched agreed to participate in this study. The weight of the backpack was set to 0%, 5%, 10%, 15%, and longus colli and SCM were measured with the ultrasound imaging equipment. The Craniovertebral angle was measured using an electronic goniometer. All measurements of the experiments were performed with the oneway repeated ANOVA.

Findings

The 30 subjects were applied weights of 5%, 10% and 15% in standing posture carrying backpacks. The thicknesses of longus colli muscle and sternocleidomastoid muscle according to the weights of the backpack showed no statistically significant differences. And The craniovertebral angle according to the weight of the backpack showed significant differences (p<0.05). Especially, in 15% of the weight of the backpack, significant differences were shown at 0%, 5% and 10%

Improvements/Applications

By participating in this study, subjects can prevent future forward head posture effectively by knowing how to change their craniovertebral angle while carrying a backpack.
