"People often take walking for granted. We just move, one step after another, without ever thinking about what it takes to make that happen. Yet every single step is an extraordinary act of coordination, driven by precise timing between spinal cord, brain, nerves, muscles, and joints. Historically, people have used stopwatches, cameras, or trained eyes to assess walking and its deficits. However, recent technological advances such as motion capture, wearable sensors, and data science methods can record and quantify characteristics of step-by-step movement."
"We are researchers who study biomechanics and human performance. We and other researchers are increasingly applying this data to improve human movement. These insights not only help athletes of all stripes push their performance boundaries, but they also support movement recovery for patients through personalized feedback. Ultimately, motion could become another vital sign. From motion data to performance insights Researchers around the world combine physiology, biomechanics, and data science to decode human movement."
Walking requires precise coordination among spinal cord, brain, nerves, muscles, and joints. Motion capture, wearable sensors, and data science enable recording and quantification of step-by-step movement. Inertial measurement units in watches and wearable sensors collect thousands of data points per second, but raw data are noisy and unstructured. Signal processing transforms sequences of measurements into usable signals, and machine learning finds patterns across continuous monitoring to yield health and performance insights. Quantified motion enables personalized feedback to enhance athletic performance and support movement recovery for patients. Continuous motion metrics have potential to serve as an additional vital sign for monitoring human health.
