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.
Dual Energy X-Ray Absorptiometry (DEXA)
The CORL supports and operates a Hologic QDR4500A fan beam dual-energy X-ray absorptiometer for assessment of lean body mass (muscle), fat, and bone composition analysis. We are also certified to perform human scans as well. Our unit's software allows for a diversity of animal subject analysis. Sub-regions of interest can also be identified and analyzed within the individual. All serial scans can be compared to previous scans with an extremely low covariance factor.
Diagnostic Radiology and Megavoltage Therapy Services
Imaging services available to the CORL through the Veterinary Teaching Hospital at WSU include the use of Radiography, C-Arm digital Fluoroscopy, Computed Tomography (CT), Magnetic Resonance Imaging (MRI), Nuclear Scintigraphy and Ultrasonography. A linear accelerator is also available for megavoltage therapy requirements for oncologic-based projects.
Material Testing Analysis
The CORL has at its disposal the use of a complete materials testing laboratory through the School of Mechanical Engineering and Material Sciences at WSU. Indentation, 4-point bending, torsial, axial compression analysis; both static and cyclic, can be performed on bone and composite materials. The CORL can also perform in vivo and ex vivo cartilage stiffness analysis using an Artscan hand-held indentation unit.
