Effect of rigid ankle foot orthoses and ankle foot orthoses with oil damper plantar-flexion resistance on thorax and pelvis movements of stroke patients during gait - Effect of rigid ankle foot orthoses and ankle foot orthoses with oil damper plantar-flexion resistance on thorax and pelvis movements of stroke patients during gait

Twenty-nine patients completed the study. Interactions were found in pelvic rotation angle, change of shank vertical angle (SVA) in stance, and paretic to non-paretic step length, which all were increased in AFO-OD group (p<0.05), the SVA decreased in RAFO group (p<0.05). The change of SVA in stance was positively correlated with the pelvic rotation in AFO-OD group. At initial contact, pelvic rotation was positively correlated with the thoracic rotation in both groups
