Description
Summary:[Purpose] To clarify effects of stance-width on gait initiation process in healthy adults, focusing on the center of gravity, floor reaction force, kinematics, and joint torque. [Participants and Methods] Six healthy adult males started to walk at their normal gait speeds after standing with 3 different stance widths (0, 15, and 30 cm). The center of gravity, center of plantar pressure, hip angle, and torque were measured using a 3-dimensional motion analysis device and floor reaction force meter. [Results] The first step width and lateral shifts in the center of plantar pressure and center of gravity were larger, and the hip adduction angle and abduction torque of the stance leg were smaller with a stance-width on gait initiation. [Conclusion] The stance width may influence the stance leg and the first swing leg in the process of gait initiation.
