The Laboratory
The biomechanics laboratory is in room 310 of the Buskey Health Sciences Building.
An 8-camera Vicon motion capture system is used to record kinematics. The system has six model T10, two model T20 cameras, and one high speed (240 Hz) digital camera. The cameras can track a marker to within +/- 0.1 mm (95% CI). Vicon Nexus 1.8.3 is used for data acquisition and Matlab 2013b is used for data reduction.
The lab contains a 7.2 m (24 ft) long elevated walkway with two AMTI model OR6 force platforms. Platform location is hidden by the square pattern painted on the walkway. These force platforms measure the ground reaction force and moments about three axes (six degrees of freedom) and are so sensitive, you can see your heart beat in the force trace.

The Laboratory has been loaned (indefinitely) an instrumented stationary bicycle from the Georgia Institute of Technology. This bicycle contains a set of dual piezoelectric element transducers mounted at the foot/pedal interface (four degree of freedoms) that allow us to measure the amount of force generated by each leg. There are only seven of these systems working in the world.
Laboratory Renovation
The next series of photographs highlight how far the lab has come since we started renovating the space to use the new Vicon Motion Capture system.

The lab was originally very cluttered. |
The beginning of our rail system. |

|
Lindsey was our first grad student. |
First data collection was Feb 6, 2013. |
Demonstration for local cyclists. |
|
Dexter and other MSPO students taking time from their summer to help rebuild the walkway. |
Fitting the top on the platform was challenging. |
Finished walkway. |

The stripes were had painted to the location of the force platforms. |
