 Another difference between the Vicon definition and the alternate definition is that the ELB target is placed on the humerus, so it shouldn't really be used to track the forearm. For this reason, in the alternate definition, a landmark at the distal end of the upper arm is used to track the forearm.

 **NOTE:** Since supination/pronation occurs by rotating the forearm, this definition is atypical and is specific to the Plug-in Gait Model. The Plug-in Gait model is created so that supination/pronation will be seen in the wrist joint angle instead of the elbow joint angle.
