-===== Example: Calculating Joint Work Using Integration =====
+==== Example: Calculating Joint Work Using Integration ====
+Determining the energy contributions of different joints during locomotion can be integral (no pun intended) to understanding the gait cycle and comparing one trial to another. Some subjects may rely more heavily on ankle propulsion, while others may see more energy production from their knees and hips as a result of factors like age or imbalances.
+Here we use **Automatic Gait Events** and **Metric Integrate** to compare the work done by a subject's right and left knees while running on a treadmill.
+First, define important gait events using **Automatic Gait Events**.
+<code>
+Automatic_Gait_Events
+! /FRAME_WINDOW=8
+! /USE_TPR=TRUE
+! /TPR_EVENT_INSTANCE=1
+;
+</code>
+Next we will compute the work done by the left and right knees by integrating knee power with respect to time.
+<code>
+Metric_Integrate
+! /RESULT_METRIC_FOLDER=PROCESSED
+/RESULT_METRIC_NAME=R_Knee_Work
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+/SIGNAL_TYPES=LINK_MODEL_BASED
+! /SIGNAL_FOLDER=ORIGINAL
+/SIGNAL_NAMES=RKneePower
+/COMPONENT_SEQUENCE=X
+/EVENT_SEQUENCE=RHS+RTO
+/EXCLUDE_EVENTS=
+/SEQUENCE_PERCENT_START=
+/SEQUENCE_PERCENT_END=
+! /GENERATE_MEAN_AND_STDDEV=TRUE
+! /GENERATE_MEAN_AND_STDDEV_ACROSS_SUBJECTS=FALSE
+! /APPEND_TO_EXISTING_VALUES=FALSE
+;
+</code>
+<code>
+Metric_Integrate
+! /RESULT_METRIC_FOLDER=PROCESSED
+/RESULT_METRIC_NAME=L_Knee_Work
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+/SIGNAL_TYPES=LINK_MODEL_BASED

+! /GENERATE_MEAN_AND_STDDEV=TRUE

+! /APPEND_TO_EXISTING_VALUES=FALSE
+;
+</code>
+new metrics have now been computed, the work, mean work, and standards deviation of work done for the left and right knees. Comparing the work done in each stride and mean work done for the left and right sides will help to identify any asymmetry between sides.
+The results should look something like this:
