Accurately models human http://www.gunnadoo.com.au/ motion Engineers have developed an open source software package called opensim that accurately models human movement.Opensim is free and in use acrossThe world helping scientists understandThe complex forces of movement to improve diagnosis of physical disabilities and prevent harmful wear and tear.In a new exhibit atThe leonardo, a science and technology museum in salt lake city, a team of stanford engineers is demonstrating an open source software package called opensim that accurately models human movement.Opensim is free and in use acrossThe world helping scientists understandThe complex forces of movement to improve diagnosis of physical disabilities and prevent harmful wear and tear.There are 640 muscles inThe human body, or maybe it is 639.Or maybe it is 850.Or 656.It all depends on whom you ask.In any case, it is a lot.Stanford bioengineer scott delp knows;He has programmed almost every one into his latest work, opensim, a software application that helps medical professionals and bioengineers study, diagnose and correct abnormalities in how people move.InThe legs aloneThere are more than 100 muscles, virtually every one necessary to maintain balance and walk properly.Most of us takeThese for granted;They just work.But for some,They don’t.Scott delp, a professor of bioengineering, mechanical engineering and orthopedic surgery, helpsThese people.And now, opensim will be on display atThe leonardo, a science and technology museum in salt lake city.Opensim is part of an exhibit exploring human movement.More than child’s playthe idea to unite museum and modeling software wasThe brainchild of andy anderson, a research assistant professor atThe university of utah school of medicine.He was a visiting scholar working with delp and jennifer hicks overThe summer and he putThe pieces together to get opensim involved withThe exhibit in his hometown, salt lake city.The leonardo exhibit is really two exhibits in one.InThe first section, visitors walk across a pressure sensitive floor and are presented atThe other side with color coded print outs ofTheir weight distribution, identifying even slight imbalances that might be putting undue stress onTheir limbs and joints.Such stress can lead to pain or arthritis.Over a lifetime, even relatively minor abnormalities can compound until hip and knee replacement surgeries become necessary. “This one is fun because people can insert various orthotics inTheir shoes and see howThey affectTheir movement.It’s quite telling,”Said anderson.The second exhibit is aimed at kids.To makeTheir research more approachable for a younger audience,The opensim development team is creating an interactive soccer game.The real world player adjustsThe strength of two leg muscles onThe simulated soccer player to generateThe force necessary to kick a virtual ball into a virtual goal. “This is a simplified version of our software, but by honing things down to just two muscles we can makeThe science of movement something kids can understand and have fun with,”Said hicks, a mechanical engineer andThe opensim project manager at stanford. “Most importantly, it is based on real physics and realistic physiology, so it really teaches as it entertains. “”Human movement is incredibly complex,”Said hicks. “The kids’ first instinct is to crank upThe muscles to full strength, but this has unintended consequences, asThe kids quickly learn. “Future possibilities for opensim are many.It can help determine whether a simple surgery to lengthen a specific muscle might help victims of cerebral palsy.It can predict how simple changes in gait might reduceThe incidence or severity of osteoarthritis.In addition to helping millions delay or avoid costly hip and knee replacements, opensim could help inThe development of new, more sensitive prosthetics, able to read and interpret electrical impulses to controlThe devices.For all its technical wizardry, however,The greatest fact about opensim may be that it is open source.Anyone with a computer and an internet connection can haveThe software in a matter of minutes.Delp is giving it away. “Opensim is outThere and hundreds are downloading it every week,”Said hicks. “If each copy helps only one person, that’s helping a lot of people. “”That’sThe exciting thing about open source,”Said delp. “By putting this powerful software inThe hands of as many people as possible, we are setting in motion a self perpetuating research ecosystem that will build upon itself to pushThe field forward. “The above story is based on materials provided by stanford school of engineering.Note:Materials may be edited for content and length.Cite this page:Mla apa chicago stanford school of
