  4. Why Motion Capture? Planes of Motion

  5. Why Motion Capture? Joint Actions – i.e. hip http://www.brianmac.co.uk/musrom.htm http://www.physical-solutions.co.uk/articles/Understanding%20Planes%20and%20Axes%20of%20Movement.pdf

  6. Why Motion Capture? BioStage - Research • Biomechanics • Kinesiology • Exercise Science • Physical Therapy • Physical Medicine & Rehabilitation • Human Movement Science • Health, Physical Education, and Recreation • Biomedical Engineering

  7. Why Motion Capture? BioStage – Clinical Applications • Orthopaedics • Cerebral Palsy • Neuroscience • Physical and Occupational Therapy • Rehabilitation • Podiatry • Chiropractic • Posturology • Sports Medicine

  8. Why Motion Capture? BioStage – Sports Applications • Golf • Baseball Pitching and Throwing • Fitness • Biking • Tennis • Soccer • et altri

  9. Why Motion Capture? Applications and Benefits for Clinical Apps and the Academics

  10. Why Motion Capture? BioStage – Specific Clinical Use • Pre-and post surgery evaluations • Rehabilitative Treatment • Lower extremities - Gait Analysis • Upper body Analysis • Orthopaedic Joint Replacements • Posture Analysis • Orthotics and Prosthesis Development

  11. Why Motion Capture? Clinical Motion Analysis to… • develop predictive models of pathology • diagnose/quantify functional limitations • identify multi-level motion problems • document functional status • support Healthcare Research

  12. Why Motion Capture? Motion Analysis – General Benefits • Surgeon  optimize their techniques • Surgeon  design an optimal surgical plan • Surgeon  determine if and when surgery is necessary • Implant designer  improve devices • Coach  better quantify improvement / loss of performance during training • Patient  better educated by seeing changes • Athlete  better quantify improvement by comparing with other athletes • Club owner  find out if athlete is prone for injury • PT/Rehab doctor  better quantify improvement during therapy • Health care system  long-term improvement in cost and quality of treatment • Student  Easier access to motion capture technology

  13. Why Motion Capture? Benefits for Clinical Apps • Reduced patient preparation time • Easier on patients with impairments • Easier for nurses to work with patients • More natural movement leads to higher data quality • Immediate results and reports available to doctor and patient for review • True and valid data comparison over repeated trials • Reduced cost for motion analysis for the patient and the doctor • Fun 3D immersive visuals encourage patients to exercise more often • Improved exercise experience, patients are more actively engaged in recovery regime

  14. Why Motion Capture? Benefits for the Academics • Markerless system allows all students to get hands-on experience with computerized motion analysis • Streamlined real-time capture process for fixed class times and research timelines • User-friendly interfaces ideal for multi-discipline and interdepartmental use • A state-of-the-art-solution to attract students, businesses, and professionals to the University

  15. Why Motion Capture? Challenges • Tracking children • Tracking subjects with impairments (cannot stand or walk straight, arms close to the torso, etc.) • Tracking of amputees • Tracking of subject in wheel chairs, using walker, cane, crutches or other equipment • Tracking internal / external rotation • What validation have you done? • What is the accuracy of the data? • Do you have any publications?

  16. Why Motion Capture? Integration Software & Hardware

  17. Why Motion Capture? OM Motion Tracking Integrated Motion Analysis TMM Motion Analysis Software Force Plates Forces and Moments Video Kinematics EMG Muscle Activity Kinetic

  18. Why Motion Capture? Integration The MotionMonitor Kinetics Kinematics EMG Real Time Animation

  19. Why Motion Capture? Integration Force Plates • Measurement of floor reaction forces in 3 dimensions

  20. Why Motion Capture? Integration EMG • Wireless EMG electrodes

  21. Why Motion Capture? Validation and Accuracy

  22. Why Motion Capture? BioStage Model • BioStage Model • Tracking of 21 Segments • Segment length directly measured or derived from separate measurements • Static and dynamic (functional) user calibration • Length ratios based on Drillis and Contini (1966)

  23. Why Motion Capture? Joint Degree of Freedom • BioStage Model • Head/Neck: 3DoF • Neck/Upper Chest: 1DoF • Upper Chest/Mid Torso: 3DoF • Mid / Lower Torso: 3DoF • Hip Joint: 3DoF • Knee Joint: 3DoF • Ankle Joint: 1DoF • Shoulder Joint: 3DoF • Elbow Joint: 1DoF • Wrist: Locked to lower arm

  24. Why Motion Capture? Validation study in Cologne • Evaluation and Acurracy tests • Comparison with Vicon system • Jan 2010 – Jun 2010 • Goal: Proof translational accuracy of 5mm and rotational accuracy of 3deg • Problem: Reference marker-less with marker-based Institut für Biomechanik und Orthopädie German Sports Science University in Cologne Prof. G.P. Brueggemann Kai Oberländer

  25. Show accuracy Validate vs existing systems provide a fitting system that ensures precise, repeatable, consistent length measurements of human bones/segments. deliver anthropometric measurements through a defined protocol in a totally "non-invasive" method in real-time. evaluate BioStage, its performance, and to assess its accuracy, reliability and suitability for use in research, sports and clinical settings. perform an assessment of errors that affect temporal, kinematic, and kinetic variables when estimated by means of the proposed markerless system compared to the existing markerbased motion capture systems using reflective markers currently used in motion analysis. validate BioStage for biomechanical research, sports and clinical use Validation Goals
