What is FAI? • bone spurs develop on the femoral head • prevent normal motion of the hip • eventually can cause osteoarthritis of the hip
Who gets FAI? • elite child athletes (> 8 hours / week) in certain sports • hockey players • soccer players • basketball players
Wolff’s Law • Structure and shape of bones will be altered over time in response to forces placed on them.
Hypothesis Performing repetitive motions during intense training exerts a load on the femoral head and acetabulum eventually causing FAI.
Objective • Measure motion pervasively • Identify femoral shapes
Measuring pervasively • Mechanomyogram (MMG) • 3 axis accelerometer • 3 axis gyroscope • World Congress of Biomechanics
Measuring pervasively • 3 axis accelerometer • 3 axis gyroscope
Measuring pervasively Walking Quickly Accelerometer g Gyroscope deg/s Time (seconds) X plane Y plane Z plane
Measuring pervasively Up Stairs Accelerometer g Gyroscope deg/s Time (seconds) X plane Y plane Z plane
Measuring pervasively Jumping Jacks Accelerometer g Gyroscope deg/s Time (seconds) X plane Y plane Z plane
Evolution of the Hip Coxa recta Coxa rotunda • Coxa recta - run and jump • Coxa rotunda - swim and climb Horse Walrus
Characterizing shape • CT scans • Rapid prototype
Future Applications • Pilot data for grant • Focus groups include • Hockey player • Gymnasts • Dancers
