Children with spina bifida (SB) can exhibit excessive arm swing, trunk sway, and
pelvic tilt during walking. To understand the relationship between abnormal low
back forces (LBF) and gait disorders in SB, we derived a mathematical model for
evaluating LBF in this population. One unimpaired child and a child with SB were
tested. A 3D motion analysis system and force plate were used to collect
kinematic and ground reaction force data during walking. A mathematical model
created using MATLAB software was used to calculate LBF for each child. The LBF
for the child with SB was three times greater in the medio-lateral direction than
for the unimpaired child. In the anterior-posterior direction, the LBF for the
child with SB acted mostly towards the anterior trunk. In addition, the LBF of
the child with SB increased by 24.5% of body weight at the fastest walking speed.
