  • 1. A Look at Biofeedback and Interpretation of Muscle Movement
  • 2.  Physical therapy can be a generally repetitive, strenuous process that may not result in short term improvement1 To increase patient retention, we aim to increase engagement with the subject Implementation of biofeedback in the form of games could address this issue
  • 3. Signal Sleeve EZ430- EZ430- RF250 with ADS1298 RF250 TUSB410 Computer User Feedback Java Video Game Analysis
  • 4.  We are in the process of teaching our neural net to recognize a wide variety of exercises  Using the Waikato Environment for Knowledge Analysis (WEKA) v.3.6.8  Preliminary N = 10 testing has yielded approximately 100 data sets for this purpose
  • 5.  Two forms of biofeedback are under consideration  Basic Biofeedback  Game-based Biofeedback Basic shows which muscles are activated Game-based requires that an exercise be performed correctly to achieve victory
  • 6.  Videogames have been shown to be highly engaging and will hopefully lead to increased willingness or even eagerness to continue the exercises2 Add a tangible goal to the day-t0-day process of exercising: victory/high scores
  • 7.  The games must be very simple to accommodate what is essentially a 1-button input Games cannot be reflex-based or fast- paced, as this would discourage accuracy End user ease-of-use is a priority concern, making intuitive interface design paramount
  • 8.  Re-contextualized Pong:  Opponent will always play perfectly  Perform the exercise correctly to play perfectly as well  Perform correctly for long enough to win  Not reflex-based
  • 9.  Physical therapy could be improved using video game biofeedback and EMG if the two worked harmoniously in a device simple enough for patient in-home use Team ADEPT is designing and producing this device and the companion biofeedback suite We project that we will begin testing on human subjects within a month
