2. 2 Electrical and Computer Engineering Outline I.Problem Statement II.Design III.Timeline/MDR Deliverables IV.Team Roles

3. 3 Electrical and Computer Engineering 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. 4 Electrical and Computer Engineering 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
