Ergonomics and Biomechanics Products

Lumbar Motion Monitor™

The 3rd generation Lumbar Motion Monitor (iLMM3) is in production after extensive testing. Highlights include:

  • Considerable reduction in weight
  • Easier and faster setup as iLMM3 has few moving parts
  • Adjusts automatically to an individual's height/spine length
  • Simpler software set-up and data-gathering process
  • The software alerts the user if data quality is compromised

Several initial orders have already been received.

New software release: The AnyBody Modeling System v. 5.0


Spine Model Updates

The lumbar spine model in the AMMR v.1.3 has been updated with intertransverse ligaments connecting transverse processes at all levels/joints of the lumbar spine. These ligaments assist in the preservation of motion during lumbar spine axial rotation. Additionally, full sets of ligaments (anterior/posterior, ligamenta flava, interspinous, supraspinous) have been introduced to the T12L1 and L5Sacrum level.

Furthermore, integration of the force dependent kinematics (FDK) solver into the inverse dynamics analysis in the AMS v. 5 has enabled deactivation of the previously prescribed spine rhythm. Instead, the AMS computes positions of the vertebral bodies based on the muscular and external loads. This feature together with the lumbar spine ligaments enables the lumbar spine model to adapt to a natural curvature derived from gravity, passive forces from the ligaments, disk stiffnesses, effects of abdominal pressure, and muscle forces acting during the activity being analyzed.

Finally, facet joints have been added to the model. The model facet joints have the ability to limit the motion of the lumbar spine. Facet joints also create contact forces between superior and inferior articulate processes of adjacent lumbar spine vertebrae. These contact forces in conjunction with the FDK enables contact between the vertebrae and control the spine curvature by reducing unnatural motion of the components of the lumbar spine.

Dynamics Stabilization Device Model

The new updated spine model supported by the new force-dependent kinematics feature in the AMS v.5.0 has been brought into use for a new model example featuring a dynamics stabilization device.

This model replicates a typical design with a titanium rod with two clamps, which are rigidly screwed to the pedicles of adjacent vertebrae on both lateral sides of the spine. In the example the device is attached to L4 and L5 vertebrae. The model enables easy exploration of design options. It is included in the AMMR v. 1.3 which is available to all new users of AnyBody as well as existing users on active maintenance.

Modeling Non-Conforming Joints and Soft-Tissue Governed Displacements

The new AMS v. 5.0 features a new method aimed at handling small displacements (motion) that is insignificant to the gross motion and therefore typically impossible to measure (by e.g. MOCAP), but which may be important e.g. for a joint configuration, i.e. relative positions, reaction forces directions, muscle/tendon moment arms, etc. We use the term force dependent kinematics for this coupling of kinematics and kinetics.

Typical application areas include non-conforming joint modeling, such as advanced modeling of knee joints and inter-vertebrae joints, and soft-tissue governed displacements for instance displacements that are highly controlled by ligaments and other soft tissue.

Force dependent kinematics is fully integrated into the existing inverse dynamics solver in the AMS. Recall that inverse dynamics implies that the kinematic analysis is independent of the forces, and that the motion is completely specified by the user. Inverse dynamic analysis then calculates the forces needed to govern that motion. In contrast, force dependent kinematics essentially implies that the mechanical system is kinematically indeterminate. Therefore, Anybody now supplies a solver that couples the inverse dynamics solver with a quasi-static analysis of user-selected degrees of freedom when the kinematic force dependency is not influencing the gross motion significantly.

The same approach enables analysis of non-conforming joints, soft-tissue governed displacements, and similar phenomena without compromising the advantages of the efficient and highly versatile inverse dynamics approach used by AnyBody.

Gait Model Updates Streamlining Gait Analysis

GaitLowerExtremityProject is a new model included in the new AMMR v. 1.3. It streamlines gait lab work data workflow by enabling simple and fast loading of the model with new C3D marker data using new facilities in the AnyScript model language supporting graphical model interaction. GaitLowerExtremityProject is based on the existing, validated GaitLowerExtremity model.
