The Gait Analysis Laboratory
The CORL supports and operates a kinetic gait lab to assess ground reaction forces produced by dogs and humans using one AMTI OR6-6 and two AMTI OR6-7 strain gage-based force plates (3). The integration of our force plates with the current version of Acquire software allows for the measurement of the three orthogonal ground reaction forces and accompanying moments: mediolateral (Fx), craniocaudal (Fy), and vertical (Fz). In addition to kinetic gait analysis using the force plate, the CORL also implements kinematic gait analysis using 4 motion capture cameras and Vicon kinematic software suite. This allows for the characterization of joint movement during gait. The CORL also performs research with surface-electromyography to further characterize gait. In order to obtain objective activity data of subjects at home while enrolled in clinical studies, the CORL fits each dog with a Philips Respironics Mini Mitter Actical accelerometer. This technology gives an objective activity measurement at chosen epoch lengths throughout the course of the study.
