Golfing with Science: A Wearable Device for Measuring Golf Swing Biomechanics

Stanford scientists in the LPCH Motion & Gait Lab, Department of Orthopedic Surgery, and Ladd Lab have developed a biomechanical analysis of the golf swing using a lightweight, wearable, and wireless device that monitors a player's golf swing on the course to give real-time, lab-validated insights for improved performance and reduced injury. The device consists of a pair of coin-sized IMUs (inertial measurement units) placed on the skin at the upper and lower spine that allow the user to measure and analyze rotational biomechanical parameters like the S-factor (shoulder obliquity), O-factor (pelvic obliquity), and X-factor (relative hip-shoulder rotation), which research indicates are strong determinants of clubhead speed at impact (CSI) and driving distance. By collecting rich kinematic data that can be communicated to a mobile device or tablet, this technology allows real-time golf swing feedback and monitoring and comparison to pro benchmarks to enhance the player's performance over time. While the technology is validated for golfing, it could be extended to a variety of sports like martial arts, baseball, tennis, and more.
