Motion-capture cameras used in the Gait Lab have strobes of LED lights that flash 120 times per second, capturing the positions of reflective markers placed on patients' bodies.
Software turns this data into a composite 3-D view.
The lab's computer also registers weight on the force plates under the floor.
The Gait Lab sits on a sunken, isolated slab so that its data will not be affected by outside vibrations.
The floor is raised to accommodate eight force plates, including two in the treadmill.
