Methods: The subjects were 10 healthy country, two male students (age 13.5 ± 0.53 years, BMI was 18.25 ± 1.04 Kg / m 2), slung the usual manner, respectively, re-position high back (on the anterior superior iliac spine ), back re-position (greater trochanter), re-position the low back (greater trochanter - knee, ankle outside the midline) and did not back heavy to bear four different conditions on the treadmill. In this study, Kinema Tracer 3D motion analysis system (Kissei Comtec) joins four aircraft speed camera (60Hz) to capture temporal and kinematic parameters of gait body.
Results: (a) re-position stepping back under different long-standing period, swing your feet to stand on stage and there was no difference (two) different back torso angle statistically significant level re-position, re-position back and tall in the back Heavy weight back position is greater than the position of the low back and no heavy weight position back no more than low back heavy (three) different positions of the body weight back torsion angle was not statistically significant, the variation of the body to reverse the district level of statistical significance, no back weight when with high-back position is greater than the weight of heavy high-back position. (D) hip angle position under different weight back statistically significant level, which in the preferred side, back position and low weight no greater than the weight back, low back and re-position tall without back heavy; non-dominant side, back re-position high, medium and low weight greater than without back.
