Abstract
The dynamic margin of stability (MoS), defined as the difference between the anterior boundary of the base of support and the extrapolated whole-body center of mass (WBCM) at foot touchdown, reflects the control of gait dynamic stability. This study explores the behavior of MoS during level walking in able-bodied walkers (n = 10) under altered sagittal trunk orientations, including ~30°, ~50° and maximal trunk flexion from the vertical compared with upright posture. Exploiting compensatory kinematic adjustments (e.g., crouched lower-limbs) possibly allowed participates to control their postural stability, as increasing trunk flexion did not lead to a significant diminish in the MoS relative to regular upright walking. Our findings might be of clinical interest to clinician interested in the nature and impact of alteration in trunk geometry on the control of gait dynamic stability.
