Intentional slips while walking: exploring the association between segmental kinematics and stability estimates

This study examined the associations between standard walking stability measures [Feasible Stability Region (FSR) and Margin of Stability (MOS)] and linear velocities of the torso and pelvis segments during intentional slips in 17 young healthy participants. MOS was related to anterior/posterior segment velocity across major slip events while FSR was more related to vertical segmental velocity during the slip itself. These data may have implications for fall detection and segment velocity profiles derived from an intentional slip could potentially inform the requirements for a stable gait.
