 The placement of markers during static and dynamic trials can significantly impact the accuracy of the data that is captured. In this static trial markers were only placed on the lateral sides of each leg, with some being nearly co-linear and some incorrectly aligned with anatomical features.  The placement of markers during static and dynamic trials can significantly impact the accuracy of the data that is captured.

-The closer markers are to being placed co-linearly the more difficult it is to define all six degrees of freedom, this can cause error to be amplified leading to an incorrect model+The closer markers are to being placed co-linearly the more difficult it is to define all six degrees of freedom, this can make the model more sensitive to noise
  
-In this trial, and many others, markers are only placed on the lateral side of each leg. This is done to avoid markers being knocked off during movement trials, however having markers on the lateral and medial side (at least for static trials) helps to improve model accuracy.+In this trial, like many others, markers are only placed on the lateral side of each leg. This is done to avoid markers being knocked off during movement trials, however having markers on the lateral and medial side (at least for static trials) helps to improve our ability to define segment coordinate systems.
  
-The placement of the foot markers, especially the heel, in this trial made it challenging to properly define foot positioning. The Toe_Z landmark was added as a solution to this error.    +The placement of the foot markers, especially the heel, in this trial made it challenging to properly define foot positioning.
