Objective: This study will measure the geometric and pressure centerlines of the foot’s plantar region in healthy Chinese youth to construct a gait norm. Methods: In the present experiment, 203 healthy college students and postgraduates (90 males and 113 females) were recruited as subjects. Their average age was 22±5 years old, average height was 164.6±13.6cm, and average weight was 58±10.4kg. A double-blind method was used in this experiment. The plantar pressure and gait parameters of time and space among subjects were tested using a gait and balance function-training evaluation system. Data were collected using five pressure-sensor plates, based on the distribution in the geometric and pressure centers of the foot’s plantar area, according to the calculation formula of biomechanics. Results: From 20 selected subjects, the experiment gathered a total of 197 data points from the plantar pressure during walking. The results defined the foot’s centerline of maximum pressure while walking and showed that the pressure and geometric centerlines tended to converge and overlap in normal youth, irrespective of gender. In addition, differences were found between the foot’s centerline of pressure and the geometric and pressure centerlines of the plantar. Conclusion: This study showed that the plantar’s pressure and geometric centerlines can be used as a reference to assess normal gait in Chinese youth.
