  1. Applications of Medical Informatics -Robotic Arm & Virtual Reality Date: 11/14 Reporter: 盧紀邦

  2. Outlines A. Robotic Arm B. Virtual Reality (VR) C. VR + Robotic Arm • Benefits & Limitations • Summary

  3. Robotic Arm

  4. Robotic Arm Combined technologies: • (Bio-)mechanics • information technology (IT) - data processing, programming, information management.. For therapy: • Medicine, rehabilitation, exercise science...

  5. Robotic Arm Digital Control (Feedback): • Input (sensor) • Process (decision) • Output (motor) • Loop (repeat) • For Brain Injury: Stroke Functions: A. Compensation B. Training

  6. A. Compensation • Performance↑ • ex: reaching, feeding...

  7. B. Training • Passive: ↓Limitation • Active (Robotic Therapy) : ↑Recovery

  8. B. Training - Passive • Maintain Functional ROM, ↓ stiffness • ex: Continuous Passive Motion (CPM)

  9. B. Training – Active (1) • with resistance • Strength, Endurance↑ • ROM, Velocity↑ Kinematic Constraints Unicycle Two-Link Arm (UTLA) Northwestern University Mechanical Engineering Dept. Laboratory for Intelligent Mechanical Systems

  10. B. Training – Active (2) • With Target • Motor control↑

  11. B. Training – Active (2) MIT-MANUS • Robotic Therapy on Motor Impairment and Recovery in Chronic Stroke. 1998~ Massachusetts Institute of Technology (MIT) Department of Mechanical Engineering & Department of Brain and Cognitive Sciences. 1994~

  12. Virtual Reality (VR)

  13. Virtual Reality (VR) Combined technologies: • Motion Analysis & Motion Capture • 3D Model • IT • (Bio-)mechanics For therapy: • Medicine, rehabilitation, exercise science...

  14. Virtual Reality (VR) A. Virtual Environment: vision + audition + (olfaction, temperature, tactile, vestibular...) B. Reality Motion (virtual manipulate) role play, motion capture feedback → virtual environment Types: • Open VR • Close VR

  15. Motion Capture • VICON • Motion Capture Data + 3D Model +

  16. Open VR → ex:

  17. Close VR

  18. Virtual Reality (VR)＋Robotic Arm

  19. VR + Robotic Therapy (1) Physical Medicine and Rehabilitation, Mechanical & Biomedical Engineering, Northwestern University

  20. VR + Robotic Therapy (2) • Robotic Arm for Stroke Victims • Doctors and Engineers Develop Virtual-Reality Recovery for Stroke Victims. 2005 IEEE-USA and the Human Factors and Ergonomics Society

  21. VR + Robotic Therapy (3) Hocoma - Armeo® 2006 • task-oriented upper extremity therapy • stroke, traumatic brain injury or other neurological diseases and injuries. • an adjustable arm support • augmented feedback • a large 3-D workspace : allows functional therapy exercises in a virtual reality environment.

  22. Benefits & Limitations Benefits: • objective, quantification • purposeful, Interaction → enjoy↑ • risk↓ • manpower ↓ • space : Limitations: • cost • maintain • multi-disciplines

  23. Summary • Clinical evidence : • physical performance maintain: ROM, strength… • motor recovery in stroke. • cognition rehabilitation. • now & future … • OT Roles ? Effects of robotic therapy on motor impairment and recovery in chronic stroke. 2003 ~
