Objectives
Narrative objectives1
In current research, comprehensive assessing of the postural, and gait's kinematics and kinetics variables by specific instrumented treadmill (Gaitway) will be done while carrying tow types of school pack in zero, 7.5, 10, 12.5 and 15 percent of body weight and in low and middle of back so that eventually help choosing good pack and carrying method.
Basic objectives2
Others
Basic objectives -Others
carrying backpacks have been suggested to be a risk factor for musculoskeletal pain and disorders, so prevention by safe methods is worthwhile
