Abstract:

Patients with progressive neurological disorders such as Parkinson’s disease, Huntington’s disease, and Amyotrophic Lateral Scle- rosis (ALS) suffer both chronic and episodic difficulties with locomotion. Real-time assessment and visualization of sensor data can be valuable to physicians monitoring the progression of these conditions. We present a system that utilizes the attention based bi-directional recurrent neural network (RNN) presented in [2] to evaluate foot pressure sensor data streamed directly from a pair of sensors attached to a patient. The demonstration also supports indirect streaming from recorded sessions, such as those stored in a FHIR [1] enabled electronic medical records repository, for post-hoc evaluation and comparison of a patient’s gait over time. The system evaluates and visualizes the streamed gait in a real time web interface to provide a personalized normality rating that highlights the strengths and weaknesses of a patient’s gait.
