The Center for Motion Analysis is designed to support a broad scope of both clinical and research oriented projects. Clinically, the center can provide gait analyses for both pediatric and adult patients, which enhance diagnoses and improve functional outcomes for neuromuscular impairments and dysfunction caused by other deformities.
Motion abnormalities include complex alterations imposed by the skeletal and neuromuscular systems, as well as secondary adaptations that the patient makes in order to function. Identification of these patterns is extremely difficult, even for the trained clinician.
Quantitative motion assessment includes specialty models for the distal extremities (foot and ankle, upper extremity, hand and wrist, trunk) sports applications and higher speed analysis capability, and rehabilitation (assistive devices, prosthetics and orthotics.) Educational support through clinical training and research project participation is provided for research fellows, orthopaedic residents, medical students and engineering students. Numerous technical development projects are supported through close collaboration with the Department of Biomedical Engineering at Marquette University. The center also collaborates with Children’s Hospital of Wisconsin, Froedtert Hospital, and other institutions (MSOE, UWM and CUW).
Research applications include studies of surgical intervention, orthotic and prosthetic treatment, and therapy upon upper and lower extremity motion and control.
Motion analysis provides a frame-by-frame analysis of the three-dimensional joint motion, limb kinematics, kinetics, and muscular activity. While changes from activity patterns of age-matched normals are used to formulate a clinical treatment plan, research studies of pathological motion and muscular control patterns are designed to increase our understanding and ultimately our ability to improve future treatment.
The Center for Motion Analysis facility provides a 2,325 square foot test area, examination/preparation area, office and storage. A 30-foot walkway is included in the test area for collection of ambulatory data. A 1,071 square foot area is located adjacent to the testing area for support personnel and includes an examination room, equipment storage room and test bench, two offices and a working community area for fellows and students.
The laboratory equipment includes a Vicon multi-camera 3-D motion analysis system, four force plates, two surface EMG systems, a EMED pressure platform, a Pedar insole pressure measurement system, a Biodex rehabilitative treadmill, and a Biodex extremity evaluation system, etc.
