  • Transcript

    • 1. Boston Code-a-Thon Team Triangle: Claus C Becker, Greg Borenstein, Johnny Hujol, Daniel Karlin, Greg Kust, Francis Yee Project Triangle: Proof of Concept Using Kinect for Assessment of Tremor in People with Movement Disorders February 19, 2011 Copyright 2011: Team Triangle
    • 2. Executive Summary
      • Self-selected to work together on device-based health-assessment problem
      • Focused on disease where diagnosis and evaluation is movement based
      • Developed Kinect-based application to enhance clinical assessment using home-grown and open-source code
      • Suggest scorecard report for physicians
      February 19, 2011 Copyright 2011: Team Triangle
    • 3. Overview of Movement Disorders
      • Many diseases impact movement. We chose to focus on pure movement disorders (MDs)
      • MDs are neurological conditions that effect the speed, fluency, and ease of movement; and the ability to stop movement
      • Different kinds of MDs
        • Dyskinesia: abnormal fluency or speed of movement (tardive dyskinesia)
        • Hyperkinesia: excessive or involuntary movement (huntington chorea)
        • Hypokinesia: slowed or absent voluntary movement
      February 19, 2011 Copyright 2011: Team Triangle Our approach will complement clinical practices for the three types of MDs
    • 4. Current Gaps
      • Problem
      • Current practice does an inadequate job of standardized assessment of MD and the frequency of the evaluations is too low. There is interest in daily (morning & night) tracking. A simple, at home data capture device may help to assess:
        • Disease progression, on a more granular & temporal basis
        • Response to therapy (e.g. efficacy, dosing, adverse events)
        • Adherence to therapy
      • Needs
        • Adherent & non-adherent progression measures
        • Utilize Kinect device to measure range of movements
        • Provide clinicians with more meaningful patient movement samples
      February 19, 2011 Copyright 2011: Team Triangle
    • 5. Our Approach: automate Abnormal Involuntary Movement Scale
      • We built a Processing application that uses PrimeSense’s OpenNI middleware and the OSCeleton library for the Kinect to capture joint position data from the user
      • Our application tracks movement of the knee and hands over a ten second period and then displays user score based on the quantity of involuntary motion detected

    • 6. Impact on Health
      • Customized care
        • Clinical effectiveness & dose modification
        • Engaged patient participation
        • Adherence measures
          • e.g. prescription status (medication possession ratio [MPR])
      • Clinical scorecard: Severity score compared to baseline
        • MPR* + Patient self report + TTAS** = Health Score
      • Other applications
        • Tardive dyskinesia, Parkinson’s, Huntington’s
        • Movement disorders associated with drug side effects
      February 19, 2011 Copyright 2011: Team Triangle **TTAS: Triange tremor assessment score; *MPR: Medicine possession ratio
    • 7. How TTAS might be used
      • At home or in the doctors office
      • Before and after taking medication to estimate effect
      • Daily to track progress (many data points to overcome noise)
      February 19, 2011 Copyright 2011: Team Triangle
    • 8. Issues we wrestled with
      • Optimizing distance to and interaction with the Kinect
      • Defining normal level of involuntary movement
      • Software limitations in initializing device
      • Regulatory approval issues – device results not sufficiently validated for use in clinical treatments
      February 19, 2011 Copyright 2011: Team Triangle
    • 9. Next steps
      • Refine software to include directions (e.g. ‘raise arms higher’)
      • Expand TTAS to entire AIMS scale
      • Improve statistical treatment of data
      • Clinical base-line and validation
