Gait Analysis

The kinematic gait protocol utilizes the APAS. The Examinee is asked to perform a relaxed and natural walk. The walk is filmed with several special video camcorders for later computer analysis. The protocol is performed several times. The walking field is pre-calibrated for accuracy. The video data is computer digitized and transformed to a 3d model of the Examinee walking. The 3d model is analyzed for dynamic joint displacement, velocity and acceleration for each relative joint. After a thorough discussion and agreement of understanding by the Examinee, the protocol commences.

Preparation

  • APAS - CAPDV;
  • Chair
  • DV Camcorder with firewire connection to the data collection computer;
  • Calibration frame.
Large frame Small frame

Room Setup

  • Clear the working area of any obstructions that may block the camera views.
  • Place a reflective marker (fixed point) anywhere in the view where the Examinee or Assistant/Examiner will not block it during motion.

Camera Setup

  • Look through the viewfinder, make sure you can see the entire frame - plus enough space surrounding frame - to film the entire sequence.
  • Set focus to auto focus then back to manual focus.
  • Set shutter speed at 1/250 s.
