Biomechanics of Movement | Lecture 10.7: OpenSim: A Powerful Tool for Muscle-Driven Simulation
Hi Prof I have been watching your videos and they have really helped me in understanding more about simulation.
Why the fuk am i watching this
I'm watching this to help myself better recover from knee pain, which caused me difficulty in walking as well as some other physiological pain in my legs!
Dear Professor Delp, your story is very inspirational. I am also trying to learn biomechanics to help with my own movement issues. I never truly had an interest in biology, but since sustaining a knee injury that required me to have an arthroscopy 6 years ago, (an injury that still has lingering effects on me to this day) I've become very interested in applying the skills I developed through my physics degrees (BS, MS, and PhD) to understand how to move more optimally in my day-to-day life and help others in my family who have their own movement issues. Thank you for all the hard work, and I look forward to watching all the videos in this course and reading the book!
Recent Physics PhD graduate here, and admittedly, biology was NOT one of my preferred subjects in school. However, as a former athlete who has sustained numerous injuries (especially with my knee), I've recently developed an interest in biomechanics and the physics of our bodies. I've gotten a copy of your book and am excited to watch these lectures to help improve my understanding of the human body and also understand how to optimize my own movement patterns!
Thanks Prof. Scott.
22:40 Decmposed is right behind you!!!
Beautiful and professional
Force velocity relation sir could you explain
Thank you for your lectures and for preaching and practicing Open Science! Very motivating!
Super helpful video, thank you!
Mr. Delp, Counld I have the names of those books in your videos?
This is both complex and beautiful. In my profession (Dentistry) this is never understood or considered. What you have ignored is the affect of balance or posture of the body over the feet, and the posture of the head (forward head posture, lordotic curve of the cervical vertebrae, posture of the mandible, etc. Head are heavy, 8 to 16 pounds, and are not just able to float to where it is biomechanically ideal, but due to muscle limitation, connective tissue adhesions, etc, the heads remain forward. This has everything to do with patient airway and occlusion, jaw size, cervical lordosis, etc. A forward head posture is a common outcome. This will alter the balance of the body over the arch or over the balls of the feet. The body may be forward or arch back like a banana. My question is do you have the biomechanics of the kinetic chains of muscles, ligaments, and tendons that include the upper extremities with altered jaw posture, and body lean? Interesting and detailed material. here. Kudos to the course. Please reach out any time. Dr. Curtis Westersund curtis@cooltodrool.com
hi, tanks for the explanations, where is the iscio muscle work in here? Thank you
thanks for the lecture, and it seems that, the sum should appear at the first equation rather than the end?
thank you actually helped me understand biomechanics whereas my lectures at my university failed to do so:)
Dear Professor, Have you come across any sources that demonstrate how acceleration measurements are mapped onto a human running cycle?
can i ask you how you made that device, i want to make my own for fun
Look up muscle stimulator
thank you sooooooo much
Thank you for your work! It's inspiring me on my journey to understand how we humans can move more efficiently and gracefully!
What a powerful Lecture by Prof.Scott. Thankyou.
Is there anyway I can get a list of all the math prerequisites to be able to be fluent in biomechanics.
Thank you for your lectures. I feel I have better insight into biomechanics.
This are the kinds of content that God sends chosen ones to find out.
3rd row in the final Matrix had some interchanged values pls check it before using as it is. T1-T2+Fx1r1S(thi1)+Fx2(l1-r1)S(thi1)-FY1r1C(thi1)-Fy2(l1-r1)C(thi1)=I1.(thi1)''
Ha, I thought I had the wrong video for a second :) well done thank you for this just makes the book that much better
It's such a privilege to watch this video from Brazil. Thank you for the time and effort put into those lectures.
I presume that the force-length property could be the best explanation to answer why we could push easier than to pull an object
Thank you for such great content. Nice blend of theory and experiment. The risk-reward of becoming bipedal seems to have paid off.
Art Kuo!
Thank you! Great info
I really love the format. Where can I find Lection 2.4 and 2.5?
The numbering changed probably at some time -> you'll find the next video in lecture 2 as 3.4 (ua-cam.com/video/Iz6t9ZnviiQ/v-deo.html)
Thank you so much!
What does "r" represent?
That’s really helpful
Bone pins for students who score less than about 65% in the midterms. 😂 You are a great teacher man.
Thanks for sharing your knowledge!
Very important concept
Thank you so much, Scott and coworkers!! This is a lecture to represent a part of this amazing study.
Note that the presenter says "medial malleolus" but it should be "medial femoral epicondyle."
Thank You realy importand subject
The screaming skeleton is a nice touch at the end.
The signal is also filtered, and the graph shown is then the envelope of the filtered signal at minute 13.
good lecture thanks a lot
Very perfect lessons 🥰
How would I get in touch with Scott Delp's about alternative biomehcincs to study? More specifically, in regards to the spine.
This is incredible... high quality information from a professional. Thank you!
The bicycle gear analogy was very good; it well explains the physical mechanism of optimal locomotive velocity.
Great review of Biomechanics and Kinesiology!
