Abstract

|
|
Purpose : The study was designed to identify the change of body alignment according to surface during walking with backpack.
Methods : Healthy twenty people(10 men & 10 women) participated in this study. The exclusion criteria were orthopedic and neurologic disease. Initial alignment measurements were performed. Results were evaluated by angle and range from earlobe to acromion, acromion to malleolus and earlobe to malleolus in the GPS system.
Results : On the hard surface, the distance and angle from malleolus to earlobe increased after walking with backpack which is 20 % of weight(p<.05). In addition the distance from malleolus to acromion and the angle from earlobe to acromion increased(p<.05). On the soft surface, on the other hand, the distance and angle from malleolus to earlobe decreased after walking with backpack which is 20 % of weight(p<.05). There was no relationship between the change of the surface and the body’s alignment(p>.05).
Conclusion : Consequently, the body alignment was changed by backpack which is 20 % of weight, but body alignment wasn’t changed by the surface. So more study need to be surveyed regard of this.
