Quantification of Agility Testing with Inertial Sensors after a Knee Injury.

Introduction: A common criterion in decision making regarding return to sport (RTS) after knee ligament injury is that athletes should achieve symmetrical bilateral movement between the injured limb and the noninjured limb. Body-worn wireless inertial measurement units (IMU) can provide clinicians with valuable information about lower-limb kinematics and athletic performance.

Methods: The IMU-based novel kinematic metrics were developed.
