Markers Sets




Dear Mr. V´┐Żnttinen:

APAS Gait currently supports the following 5 marker sets:

  1. Helen Hayes Original;
  2. Helen Hayes Modified;
  3. Vaughan Original;
  4. Vaughan Modified;
  5. Sun.

The desired marker set can be chosen in the 'general settings' tab of the current gait analysis. You will find the recommended marker locations for each marker set described in the APAS Gait documentation.

For Kistler platforms the following channel order is assumed for calculating moments and torques: Fx12|Fx34|Fy14|Fy23|Fz1|Fz2|Fz3|Fz4.

I hope this answers your questions.

Best regards - Rudolf Buijs, Ariel Dynamics Inc.
