  <brief_summary>
    <textblock>
      Previous reports have the evidence implicating gait velocity may affect kinematic parameters.&#xD;
      However, how the gait velocity will influence kinematic parameters remain unclear. The&#xD;
      purpose of this research is to find out kinematic characteristics among different gait&#xD;
      velocity. To do this, it will provide a reference for future prospective studies or&#xD;
      investigations and make us fully understand the impact of gait velocity.&#xD;

Previous reports have the evidence implicating gait velocity may affect kinematic parameters.
      However, how the gait velocity will influence kinematic parameters remain unclear. The
      purpose of this research is to find out kinematic characteristics among different gait
      velocity. To do this, it will provide a reference for future prospective studies or
      investigations and make us fully understand the impact of gait velocity.
