Force Platform

Horizontal forces occur in every walking step allowing us to move forward or backward. By analyzing these forces and the three-dimensional movement data collected from the reflective markers and cameras, we can determine any unusual stepping characteristics that may occur.

It's common for a motion analysis lab to be equipped with at least two force platforms. They're normally installed within a raised floor so that the topmost surface of each lies flush with the surrounding floor. This allows the platforms to be inconspicuous, yet still allows subjects to tread upon them as they walk.

The hollow, raised floor also conceals power and data cables connected to the force platforms. The platforms are also frequently installed on extremely heavy, precision-milled metal "slabs" within the floors. The mass of the slabs helps reduce unwanted vibrations from the surrounding building into the platforms.
