Biomechanics model CLAUDIUS includes: * Full-body kinematic modelling with constrained or unconstrained joints * Scaled segment model for display of rendered bone mesh animations in Polygon * Muscle attachment and wrap-point model for display of rendered muscle animations in Polygon * Lower-body kinematic (inverse dynamics) modelling * Flexible whole-body marker set support * VICON Clinical Manager marker set support and model emulation Model Outputs for Tabular or Graphical Presentation: * Joint Angles (3-component, bilateral) for: Neck, Lumbar Spine, Shoulder, Elbow, Wrist, Hip, Knee, Ankle, Foot * Global Angles relative to Anatomic Axes for: Head, Thorax, Pelvis, Foot Progression * Muscle Attachments, Wraps, and Lengths (bilateral) for: Upper Trapezius, Upper Splenius Capitis, Sternomastoid, Biceps Brachii, Brachialis, Brachioradialis, TricepsBrachii, Long Head Pronator Teres, Short Head Pronator Teres, Flexor Carpi Ulnaris, Flexor Carpi Radialis, Flexor Digitorum, Extensor Digitorum, Mid Trapezius, Lower Trapezius, Pectoralis Major, Upper Latissimus Dorsi, Lower Latissimus Dorsi, Psoas, Iliacus, Gluteus Medius, Rectus Femoris, Semimembranosus, Biceps Femoris, Adductor Magnus, Gracilis, Vasti, Lateral Head Gastrocnemius, Medial Head Gastrocnemius, Tibialis Anterior, Extensor Hallucis Longus * Multiple Force Plate Vectors * Resultant Forces, Moments, and Powers (bilateral) for: Hip, Knee, Ankle CLAUDIUS automatically detects the presence of various alternative marker sets and adjust the model accordingly. Supported optional markers include: VCM standard set, FullBody standard set, heel, 5th metatarsal, foot dorsum, wrist extension/medial/lateral, finger Adjustable Parameters for: Static Head Level, Static Foot Flat, Marker Diameter, Head Tilt, Lateral Shoulder Offet, Knee Width, Ankle Width, Foot Thickness, Elbow Width, Wrist Thickness, Hand Thickness Body Mass, ASIS Trocanter Distance, Femur Rotation, Tibia Rotation NOTES FOR USE ============= 1. There are 2 versions of CLAUDIUS, one of which (CLAUDIUS_FP.MOD) requires that force plate data be present in the C3D file, and another (CLAUDIUS.MOD) which does not. Both should be used with the same parameter and marker files, CLAUDIUS.MP and CLAUDIUS.MKR. Static trials are generally collected without force plate capture and should be processed using CLAUDIUS.MOD. Trials from which kinetic output is required should be processed using CLAUDIUS_FP.MOD. 2. CLAUDIUS_FP.MOD needs to be modified to expect the actual number of force plates installed and captured. Use the Find command to search for: {*Force Vectors*} Adjust the repeated lines accordingly: ForceVector(ForcePlate1) ForceVector(ForcePlate2) ForceVector(ForcePlate3) 3. A bug (to be corrected in later versions of BodyBuilder) causes scalar variables such as muscle length which are saved to a C3D file to be read back as vectors, resulting in a model processing error. Therefore, if muscle length outputs are required, the parameter $MuscleLengthsOutput should be set to 1 and the model outputs saved, using Save As..., to a file with a different name than the input file. The input file can then be re-processed without problems. 23rd October 1998
