To accurately capture whole-body kinetics, it’s essential to measure close to your body’s center of mass (COM). Over the past ten years of research, we’ve proven that using pelvic accelerometry with our specially designed running belt is effective. This method provides a practical alternative to force-instrumented treadmills, making it useful for various purposes. Our innovative algorithms allow for the precise detection of left-to-right differences without the need for multiple sensors. This not only reduces setup friction but also streamlines data synchronization, eliminating the requirement of additional sensors on shoes or shins. Moreover, our approach offers invaluable insights into how effectively lower limbs absorb shock—a crucial metric in assessing and enhancing patient rehabilitation progress. By providing this detailed biomechanical feedback, we empower practitioners to optimize rehabilitation protocols and encourage meaningful functional improvements.
