The following is how a typical motion test might progress The analysis begins with an extensive physical examination and a detailed medical history. Reflective markers are then adhered to certain anatomical positions that represent the actions of underlying joints. Other data collected at the same time might include EMG or force plate data. EMG monitors muscle activity, and the force plates help give us insight into joint forces and similar kinetic information. The markers on the patient are tracked by the six high-speed cameras that record the changing positions of each marker relative to the whole lab.
Data processing includes translating the marker location information into movements.
Alongside the visual information, the force plate information is translated through a program written in our lab by one of the mathematicians to get data such as motion and speed of limb segments, joint center rotations, joint forces and torques, and step distances and speeds. The EMG information is also processed and read to find out when muscles are activated and deactivated, and how strong the muscle activity was during the motion. All this information is then evaluated by clinical professionals to figure out how to express the improvement of the patient we tested.
