Association between improved trunk stability and walking capacity using ankle-foot orthosis in hemiparetic patients with stroke： evidence from three-dimensional gait analysis

Background Restoration of both normal movement of the pelvis and centre of mass is a primary goal of walking rehabilitation in post-stroke patients because these movements are essential components of effective gait. The aim of this study is to quantitatively analyze the effect of ankle-foot orthosis on walking ability, and to investigate the correlation between improvements in trunk motion and walking capacity.
