Goals

• To develop a simple wearable system to measure jumping biomechanics.
• To assess the capacity of this system to evaluate the risk of anterior cruciate ligament injury during jumping tasks.

Major Findings

• Sagittal plane kinematics, temporal sequence, and jump height can be precisely measured using a wearable system composed of thee inertial measurement units (arrows on the figure).
• The good discriminative performance in terms of known risk factors for anterior cruciate ligament injury suggests that this system can be used to identify movements at higher risk for injury.

Representative Publications

• A wearable system to assess risk for anterior cruciate ligament injury during jump landing: measurements of temporal events, jump height, and sagittal plane kinematics.
