Human Motion Analysis Laboratory
The human motion analysis laboratory is designed to support a broad range of clinical and research oriented projects. Clinically, it is structured to evaluate adult, foot and ankle, pediatric, sports medicine and total joint patients during ambulation and other activities. The gait lab offers comprehensive analysis of lower extremity motion, including kinematics, kinetics and EMG analysis. Typical kinematic analysis includes motion analysis of the pelvis, thigh, shank and foot in three-dimensions. Kinetic analysis includes determination of joint moments and powers. The EMG system allows for 10 distinct muscles to be tested simultaneously and correlated to specific events in the gait cycle. EMG’s can be collected on surface muscles using skin mounted electrodes or for deeper muscles fine wires can be placed as needed for recording. Age stratified databases allow for pathologic patients to be compared with age matched "normals." In addition, kinematic clinical testing is now being done on patients aged 10 and older, with a focus on the motions of the foot and ankle during ambulation.
As part of the Orthopaedic & Rehabilitation Engineering Center (OREC), educational opportunities for students are provided through clinical research project participation and interaction with medical residents. Numerous technical development projects are supported through close collaboration with the Department of Biomedical Engineering at Marquette University. A full-time engineer and a half-time graduate research fellow from Marquette staff the laboratory.
The resources provided through the Human Motion Analysis Laboratory include a testing area and an examination/preparation area. The Human Motion Analysis Laboratory clinically evaluates between two and five patients per week. Equipment includes seven motion analysis cameras, two force plates, a PC based motion analysis workstation, 10 channel EMG system, a foot insole pressure measurement system, Pentium based PCs for data analysis, and motion analysis software. The above equipment along with several resourceful, on staff, engineers allows the utmost versatility in bio-mechanical modeling.
