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.

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.
