The Comparison Between Before and After Cross Bag Walking Intervention on Gait Parameter and Center of Pressure

Abstract

Background/Objectives: Purpose of this study is to analyze quantitatively the morphological gait parameters and displacement of the center of pressure(COP) of the human body during walking before and after carrying the cross bag and utilize it for treatment.

Methods: The subjects of this study were 29 healthy adult males in S University. This study used 3D motion analyzer and ground reaction force plate. This study was conducted as a single group without a control group and compared the gait parameters and center of pressure displacement when before and after wearing the cross bag.

Findings: The mean walking speed decreased slightly (m/s) before and after wearing cross-bag, but there was no statistically significant difference(p>.05). However, when walking after wearing the cross-bag, the stride length (cm) of the left foot decreased, so there was a significant difference(p<.05) but the stride length (cm) of the right foot decreased but there was no significant difference(p>.05). The center of pressure displacement was significantly different between the left, right and left and right foot before and after(p<.05), but there was no significant difference in the center of pressure displacement between the left and right foot. The left foot was not significantly different(p>.05), but the right foot was significant (p<.05).

Improvements: It is believed that pain and other symptoms will be improved by providing the dynamic muscular strength increase with a significant recovery from the functional state of the patient by making patients with mild lesions such as mild knee arthritis or anterior cruciate ligament do cross-bag gait training.
