“…Considering the location of the backpack load, the direct effect of the backpack manifests itself on the trunk biomechanics and the indirect effect might affect the lower limb biomechanics. There is also a lack of reported lower limb injuries and disorders correlated with backpack usage [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] .…”

“…A VICON 250 motion analysis system (Oxford Metrics Group, Oxford, UK) was utilized to study The changes in the trunk and lower limb kinematics during the gait start period [15][16][17] . The studied kinematic measurements were COM displacement, COM velocity, trunk and lower limb joint movements (trunk forward-backward bending, trunk side bending, trunk rotation, hip flexionextension, hip abduction-adduction, knee flexionextension, and ankle dorsi-plantar flexion).…”

Abstract.[Purpose] The purpose of the present study was to analyze the effect of backpack heaviness on trunk-lower limb kinematics at the start of gait.[Subjects] Ten university male students (age=20.3 ± 0.98 years, height=1.69 ± 0.04 m, weight=59.5 ± 5.3 kg) participated in the present study.[Methods] Each subject was asked to stand erect then walk forward in a straight line in four modes: unloaded, and with loads of 10%, 15%, and 20% body weight (BW). A VICON 250 motion analysis system was utilized to study changes in the trunk and lower limb kinematics at the start of gait.[Results] The results show significant trunk backward lean changes between the unloaded mode and loaded modes even with no changes in the center of mass (COM), velocity or displacement.[Conclusion] A 20%BW backpack caused the highest trunk kinematic changes, so backpack weight should be limited to 15%BW. It is also important to be aware of other factors correlated to backpack usage to provide better usage recommendations.

“…A camera frequency was set at 100 Hz. This 3-D motion analysis is a widely used technique which has previously been shown to provide valid and reliable measurements for gait analysis [14]. In testing sessions, a total of 35 reflective markers (1.4-cm diameter) were attached at bony landmarks of the whole body, based on Plug-In-Gait model (Vicon, UK) (see Figure 2).…”
