Rizzoli markerset protocols are available in Motive for human motion tracking. The Rizzoli protocols are developed and researched from the Movement Analysis Laboratory in the Rizzoli Orthopedics Institute, Italy.
In biomechanics tracking applications, proper marker placements are critical to the human motion tracking and the respective biomechanical analysis; and for this reason, precise identification of the anatomical landmarks and marker placements have to be performed. In Motive:Body, marker locations are indicated over the avatar displayed in the Skeleton Pane. This page provides additional details on the anatomical locations of the marker placements for the Rizzoli protocols.
The Rizzoli Lower Body protocol (26) integrates a novel marker placement for lower body tracking. This markerset is designed to provide a complete description of 3D segment and joint motion for analyzing the pelvis and lower extremity kinematics. The following chart includes anatomical landmark descriptions of where the markers need to be placed for accurate and reliable analysis of the lower body movement.
For more information on the segment and joint definitions, please refer to the referenced research papers.
This markerset is designed for tracking multi-segment trunk kinematics. Total 10 markers are place on the torso and 4 markers are placed around pelvis, and an extra back marker (RBAK) was added on the right scapula solely for improved tracking.
For more information on the Rizzoli Trunk markerset, please refer to the referenced research papers.
The Rizzoli Body Protocol (37) combines the Rizzoli Lower Body Protocol and the Rizzoli Trunk Protocol to provide tracking of the full body kinematics.
The Rizzoli Left/Right Foot Protocols (14) provide precise tracking of the foot kinematics by modeling three-foot segments – rear-foot, mid-foot, and fore-foot – from the markers that are placed on carefully identified anatomical landmarks of the foot . The following diagrams and the chart detail on where each marker needs to be placed on the right foot protocol. The placements for the left foot will be anatomically equivalent but reflected.
There are two calibration markers in each foot protocol. They are located at the apex of the medial malleolus (RMM/LMM) and the lowest point of the heel center (RCAp/LCAp). These markers are only for creating the asset for static trials, and they need to be removed for dynamic trials.
Refer to the referenced papers for specific information on the joint and segment definitions.
