Trajectories of body landmarks in videos of cerebral palsy patients and corresponding clinical labels

Łukasz Kidziński, Bryan Yang, Jennifer Hicks, Apoorva Rajagopal, Scott Delp & Michael Schwartz
Cerebral Palsy (CP) is a neurological disorder that is usually caused by mechanical damage to the brain at or around birth. One of the main symptoms of CP is impaired motor control and development of walking skills. In clinical practice in the US child’s gait is often recorded with a camera and the recording can be used by a doctor for assessment. In this dataset we provide body landmarks (such as positions of knees, elbow,...

OpenSense: Validation of IMU-based estimates of kinematics over long durations

Johanna O'Day, Scott Delp, Mazen Al Borno, Vanessa Ibarra, James Dunne, Ajay Seth, Ayman Habib, Carmichael Ong, Jennifer Hicks & Scott Uhlrich
Here we provide the dataset for validation of OpenSense, an open-source toolbox for Inertial-Measurement-Unit-based measurement of lower extremity kinematics over long durations (10 minutes). We computed IMU-based estimates of kinematics using sensor fusion and an inverse kinematics approach with a constrained biomechanical model. We measured kinematics for 11 subjects as they performed two 10-minute trials: (1) walking and turning, and (2) a repeated sequence of varied lower-extremity movements (sitting, standing, stair-climbing, side-stepping, walking, running). Subjects...

Human runners have long been thought to have the ability to consume a near constant amount of energy per distance traveled regardless of speed, allowing speed to be adapted to particular task demands with minimal energetic consequence. However, recent and more precise laboratory measures indicate that humans may in fact have an energy-optimal running speed. Here we characterize runners’ speeds in a free-living environment and determine if preferred speed is consistent with task or energy...
