+====== How to Use Motion Capture Data in DSX ======
+The DSX Software Suite comes with knee model templates which are created for you. The model templates are used to seed the segment tracking using the motion capture data.
+If you use the same marker set with the same marker names, you can use the model templates as is. If you use different marker names, you will need to re-name the markers in the model template. If you use a different marker set, you will need to modify the model template. These changes may be done in Visual3D. Making these changes requires a knowledge of Visual3D.
+===== Preparing your Motion Capture Data =====
+Within your Motion Capture Software you must reconstruct and label the C3D files. Some motion capture vendors allow you to export the subject name as a prefix to the target labels. This option must be turned off.
+===== Knee Model =====
+Segments Tracked:
+  * Pelvis (used to define hip joint center in motion capture only)
+  * Thigh
+  * Shank
+  * Patella (using motion constraints)
+^ Minimal PiG Marker Set (NOT Recommended) ^ Knee Marker Set (Recommended) ^
+|{{:DSX_PiG_Knee_Marker_Set.png?400}}\\ \\ **Note:** The position of the subject during static calibration matters. The subject's knees should be in line with each other.  | {{:DSX_Knee_Marker_Set.png?400}}  |
+You can follow Visual3D's [[Visual3D:Documentation:Modeling:Update_DSX_Knee_Model_Template|Update DSX Knee Model Template]] guide to understand how you can customize your knee model template.
+===== Cervical Model =====
+Segments Tracked:
+  * Trunk
+  * Head
+  * C7 - C1 (using motion constraints)
+^ Cervical Spine Marker Set ^
+|{{:DSX_Cervical_Spine_Marker_Set.png}}\\ \\ Note: The subject's position during the static trial matters. The subject's head is assumed to be in a neutral position during the static trial.  |
+===== Lumbar Model =====
+Segments Tracked:
+  * Pelvis
+  * Trunk
+  * L5 - L1 (using motion constraints)
+^ Lumbar Spine Marker Set ^
+|{{:DSX_Lumbar_Spine_Marker_Set.png}}\\ \\ Note: The subject's position during the static trial matters. The pelvis is assumed to be vertical during the static trial.  |
