Location selection for optimal sensor placement for prediction of hip angle in three dimensions with wearable strain sensors

The study was conducted to determine optimal placement of strain sensors for capturing hip joint movement during running. Five subjects donned tight athletic pants having a grid of optical motion capture markers on the right hip area. The motion capture experiment was run with static pose and running at three speeds. Five participants (P01 to P05) were asked to run on a treadmill at three fixed speeds - 8 km/h, 10 km/h and 12 km/h - for two minutes per session. The set of markers were evaluated to determine which pairs resulted in greater movement in order to inform the decision of where to place future strain sensors.
