New York, 9 July 2009 As soccer continues to grow in popularity, injuries to soccer players are likely to increase as well. Certain injuries fall into gender-based patterns and new research at Hospital for Special Surgery suggests some underlying causes that could help lead to better treatment, or even prevention for present and future soccer stars.
Data presented at this year's American Orthopaedic Society for Sports Medicine meeting in Keystone, Colo., explores the differences in soccer kick dynamics based on gender. With the use of video motion analysis at the Leon Root Motion Analysis Laboratory at Hospital for Special Surgery in New York City, researchers were able to examine the dynamics of the kicking motion.
"Prior to this kick study, there had been very little motion analysis to show what was going on during the soccer kick," said Robert Brophy, M.D., lead investigator and former resident and fellow at Hospital for Special Surgery. "We know that female soccer players face a greater risk of ACL injury and patellofemoral problems and male players are more at risk for sports hernia. We used motion analysis to determine if the two types of players have different alignment and muscle activation that might correlate to the injury patterns."
During motion analysis, the kick is looked at in two different ways simultaneously. The activity of each of the muscles involved is measured based on electrical impulse. "But you also need to know what the body is doing when you are taking the readings, is it kicking? Standing? And so on," said Sherry Backus, PT, DPT, M.A., Advanced Clinician at the motion analysis lab and co-author on the paper.
"To record what the body is doing while the muscles are working, we attach bright surface markers to different parts of the body," said Backus. "Around the room there are eight to 10 cameras that are trained on the markers, recording what the body is doing. We merge the images from all of th
