A real-time, mobile timed up and go system

With the growing population of the elderly, the need for mobile health solutions is also increasing. We propose a system which allows patients to perform basic stroke rehabilitation tests from their own homes. This drastically cuts down on patient/therapist visits, freeing up therapists for more pressing work. This paper will focus on the Timed Up and Go Test (TUG) portion of our system. Our system requires very little setup, is relatively low cost, and is able to provide immediate feedback to the user. Our results show that the timing portion of the system is on par with and in some cases may be better than current physical therapy methods, with an RMSE of 0.907 seconds. Our system also tracks the angles of the knee and ankle. The knee results are more accurate than similar systems, with an RMSE of 3.03°.
