摘要：The usually used parameters to analyze the ver- tical and the antero-posterior components of the ground reaction force in different shoe conditions are reviewed. The impact force (FZI), the vertical force during the foot contact with the ground (FZA), the vertical force during the midstance (FZV), the vertical force during the toe off (FZD) and the time to the production of these forces (TZI, TZA, TZV and TZD, respectively) are pre- sented. Furthermore, the antero-posterior force during the foot contact with the ground (FXI), during the toe off (FXF) and the time to the pro- duction of these forces are also presented (TXI and TXF, respectively). The shoe condition must be controlled to analyze with force platforms the walking trials. It is recomended to standardize the brand and model of the shoe condition during the walking trials with force plaforms.
