Decline of gait ability due to aging effects: analysis of gait characteristics for korean healthy adults in the age group of 20s-80s

The purpose of this study was to determine the decline of gait ability by aging effects for Korean healthy adults in age group of 20s to 80s of 1,507 healthy adults. We conducted the uninterrupted walking of 1 min. duration on treadmill at their self-preferred walking speed using the shoe-type inertial measurement unit system. As the age progresses, the walking speed and stride length indicated the declining trend, and the age groups over the 60s age indicated significantly low values compared to the 20s age group. The GA and PCI indicated the increasing trend, and the groups over the 70s age indicated greater values compared to the 20s age group. Korean healthy adults between age groups of 60s to 80s indicated the decline of gait ability due to aging effects.
