Motion Analysis Center Consortium held at Shriners Hospitals for Children — Canada

Largest multisite database developed

Motion capture is used in the movies to make awesome special effects.It is also used in some state-of-the-art health care facilities, including 14 Shriners Hospitals for Children locations, of which the Canada Shriners Hospital in Montreal is one. Motion analysis offers an impressive tool to diagnose issues, guide decisions and track outcomes in our orthopaedic and neuromuscular patients.

The high-tech motion capture camera systems in our motion analysis center (MAC) allow our multidisciplinary teams to track the movements of children and teens as they walk, reach, push and twist. The results indicate muscle strength and cardiopulmonary fitness. The MAC provides our teams with a clear advantage as they make clinical decisions regarding surgery, braces or care, and as they evaluate treatment outcomes. Patients with cerebral palsy, osteogenesis imperfecta, scoliosis, spinal cord injury, arthrogryposis, clubfoot, sports injuries, muscular dystrophy and spina bifida, as well as other neuromuscular disorders, all benefit greatly from having access to a MAC.

In September, the Canada Shriners Hospital – one of only two pediatric centers for motion analysis in Quebec – hosted specialists from 12 of the 14 Shriners Hospitals that have motion analysis centers in an effort to bring the use of this state-of-the-art technology to a new level. “We have the largest network of pediatric motion analysis centers in the world. Further development and enhancement of sophisticated computer data analysis tools will lead to better diagnosis and treatment methods and expand our research programs in this high technology field of medicine,” explains Marc Lalande, Ph.D., vice president of research for the Shriners Hospitals for Children health care system.

With specialists coming from Shriners Hospitals in Northern California, Chicago, Houston and Lexington, the exchange of ideas and information will help the discovery of new methods and discoveries in motion analysis to further help our patient populations. One of the first steps is the development of advanced computational techniques and common databases to ensure that clinicians from different centers can measure patients the same way. Therefore, we are taking the opportunity offered by the Consortium to perform this standardization study about the reliability of gait parameter measurements when clinicians from the different motion analysis centers test the same patient. This will allow us to gauge whether results are sufficiently reliable to perform multicenter studies or if adjustments are required.

The main objective of the motion analysis center (MAC) is to evaluate the functional deficits associated with gait in children and, to a lesser extent, to detect the origin of possible functional deficits. To achieve this, MAC professional staff members use sensors placed on patients’ bodies and optoelectronic (infrared) cameras. With these technologies, it is possible to quantify the child's movements in space and time. The center team can thereby detect abnormal motion patterns and understand the biomechanical impact of these incorrect movements. The analysis is completed before treatment to provide accurate information to the health care team that will evaluate the treatment options (surgery or physiotherapy, for example). It also occurs after the treatment to measure the child’s progress following surgery or therapy.  

"Equipped with a set of markers and ten optoelectronic cameras, force plates for kinetic analysis, electromyograms to quantify muscle activation, an isokinetic dynamometer capable of measuring the forces in various joints, and many other pieces of equipment, this center allows us to optimize the care offered to patients who require intervention. It also allows the development of a preventive and cutting-edge approach in pediatric orthopaedics," explains Louis-Nicolas Veilleux, Ph.D., principal investigator at the center.  "This service allows us to improve our ability to diagnose and treat our patients,” says Reggie Hamdy, M.D., chief of staff at Shriners Hospitals for Children — Canada and director of the center. “Being part of multicenter studies within the Shriners Hospitals for Children network and hosting consortiums such as this one are extraordinary advantages as we are many working together to improve patient care.” 

The Canada Shriners Hospital Motion Analysis Center will be available to develop sports medicine evaluations, arthritis prevention and therapeutic tools. The center serves not only the people of Quebec but also people in rest of Canada and in the northern United States.
