A new method for synchronization of motion capture and plantar pressure data.
A common plantar pressure analysis technique requires dividing the pressure distribution into regions based on key landmarks of the foot. Typically, this is done using visual inspection of the footprint and is subject to error when there is abnormal foot contact. A novel, robust method of synchronizing motion capture and plantar pressure data was created that allows for motion capture markers to be projected onto the plantar pressure mat for accurate subdivision of the foot. Validation studies showed that spatial synchronization of the plantar pressure and motion capture systems was determined to be accurate within 1 sensel.
