Abstract

Purpose: Our study sought to investigate differences in plantar foot pressure as a function of type of pack carried and of changing weight during gait and stance. Methods: Subjects were 40 students with no disabilities. Plantar foot pressure was measured with different types of packs carried and with changing weight of the pack during both gait and stance and while changing feet. During stance while carrying a satchel on the shoulder caused a disproportionate change in plantar foot pressure. An even great imbalance occurred for plantar foot pressure during gait. Results: Using a satchel can influence diseases such as scoliosis that are caused by unbalanced muscle activation and by a disproportionate distribution of the weight of the body. Conclusion: Knowing how to use a pack correctly and how to appropriately adjust the weight of bag should be taught.
