Caption
A person walking in a state-of-the-art gait lab, with a wearable sensor positioned on his lower back. He is walking over a gait mat embedded with force-sensitive sensors. The gait mat provides highly accurate measures of the person's step length and is used to provide reference values for "training" and testing of the machine learning model described in this study. In the background, specialized motion capture cameras can also be seen. The gait mat and cameras very accurately measure a subject's walking pattern, over a few steps. However, these tools cannot be used in the real-world, everyday setting. In contrast, the wearable sensor is small, lightweight, and waterproof, can be held in place using skin tape, and can measure step length throughout the day, informing the evaluation of real-world walking and functional abilities.
