To increase the awareness and the eectiveness of home physical therapy routines, by providing valuable data and compliance information to stroke patients is very important in their treatment plan.

HOME REHAB


Researchable Question Sub Questions

“How can stroke patients improve their therapy and rehabilitation at home?”

‣ How do therapists decide on a course of treatment? ‣ How can a monitor/device provide benefits to patients? ‣ How could the monitor/device show patients’ improvement?

Research

Literature Review Marketing Review

Compared to traditional home rehabilitation equipment and hospital-based equipment, the market analysis for existing products reveals that there is a significant opportunity to design a device for stroke patients to do the home rehabilitation exercises.

Physical Therapy Monitoring Device Academic / Team Work Member: 7 Aug. 2016 My Work: Research, Concept Development, Animation Making, Apps Design, Product Design To increase the awareness and the eectiveness of home physical therapy routines, by providing valuable data and compliance information to patients and others involved in their treatment.

Click to Watch the Video https://youtu.be/XCbu58HlFw8


Revenue (Sales) Projections

Physical therapists need to monitor patient compliance and recovery progress but this is difficult to do when a patient leaves a treatment facility.

Design a product to allow physical therapists to track patient activity and collect data for analysis in order to translate the data into meaningful insights for all parties involved in a patient’s treatment.

Growing Physical Therapy Market

Rising Health Care Costs

Market Segments Primary Market: Physical Therapists Seondary Market: Athletes Key Partners - Orthopedic Centers - Insurance Companies - Health Care Providers - Medical Professionals - Manual Medicine Associations - Rehabilitation/Physical Therapy Centers

High Rate of Non-compliance

Improve Patient Outcomes Reduce Costs

Launch Strategy - Start-up Company: •Regional product roll-out - Future Product Expansion: •Mobile phone camera sensing to detect a user's motion •Virtual simulation application - Line extension to include: •Features that monitor form and alert a user when they are performing an exercise with improper technique •Widespread data analysis over time to help therapists develop more effective treatment plans

Profit Projections - 90% of PTs interested in IoT - Only 15% with purchase intent amid various concerns - 209,690 physical therapists practicing in the U.S. as of May 2015 - Projected percentage change in employment for physical therapists from 2014 to 2024 is expected to be 34% - In 2014, there were an estimated 9 million patients utilizing physical therapy services, annually - Demand for physical therapy is predicted to grow at a rate of 2%, annually

Value Proposition Physical Therapists: the PhysikAware™ system (i.e., the device and the asociated software applications) will help to keep track of patient activity as well as compliance for assigned home exercises. This information will help therapists with patients education and allow early intervention to reduce non-compliance. Patients: the PhysikAware™ system at home can easily obtain data about daily exercises. Patients’ progress will be analyzed and presented to them, which will help patients to gain motivation. In addition, patients will be alerted to over-exertion and improper form.
