To understand kinetic characteristics during the process of initiation of gait from standing, from the visual cue to toe off of the stance limb, vertical ground reaction forces(GRF) and center of pressure(COP) during gait initation period were evaluated with two force platforms placed side by side in thirty two adults(16 young 16 older with mean ages of 27.8 and 51.7 years, respectively) with no history of neuromusculo-skeletal abnormality.
Initiation of gait period of swing and stance limbs, percentage of gait initiation period and ratio of the vertical forces to body weight at each peak of the vertical forces of both limbs, and movement of net COP calculated from the each vertical force and center of pressure were measured and described. The results from the two groups of 16 young adults and 16 older adults were compared statistically.
These data showed the increase of initiation of gait period and the decrease of movement of net COP in older group compared with the young group and be used as a part of database when initiation of gait in subjects with neuromusculoskeletal abnormalities needs to be evaluated.
