  1. October 23rd, 2009 SDP10 - Preliminary Design Review Motion Analyzer for Physical Therapy (MAPT) Arjuna Baratham (CSE) - Sean Klaiber (EE) - James Rutter (EE) - Constantina Tyes (EE) Professor Soules Advisor, Senior Lecturer, ECE

  2. Outline • Problem Statement • Design • Timeline/MDR Deliverables • Team Roles

  3. Problem Statement Reliable Quantitative Data in Physical Therapy (PT) can only be Collected with a One-on-One Patient/Therapist Interaction - Leads to multiple visits that are time consuming and costly - PT may be skeptical of the reliability of data if not present

  4. Solution Create a simple,inexpensive, and portable device that can accurately measure physical therapy related motion - Provide exercise feedback to user with simple interface - Log exercise data for PT to analyze patient's progress - Record reliable data to ensure PT's trust in device - Reduce number of visits to the clinic

  5. Outline • Problem Statement • Design • Timeline/MDR Deliverables • Team Roles

  6. Vision of Solution

  7. Block Diagram

  8. Wireless Sensor

  9. The Wireless Sensor • Measures Range of Motion • Attached to the patient’s leg • Lightweight • Non-restrictive Φ Φ Φ Φ

  10. The Wireless Sensor • Accelerometers • Measures acceleration in 3D • Data used to calculate pitch, velocity, and position Zigbee Transmitter • 10-30 meter range • Low power output • Affordable

  11. Portable Storage and Feedback Device (PSFD)

  12. PSFD Functionality • Receives physical therapy exercise data • Compares motion data to pre-defined baseline • Provides feedback to the user • Electronic display of results and device status • Stores data in a removable memory card

  13. PT Computer

  14. PT Software

  15. Design Alternatives • More than just Kinematics Sensing • Internet-based Data Exchange • Computer-Based User Interface • Proprietary PT Software (MATLAB)
