That is really the closest thing i have ever seen to a true outcome measure tool in biomechanics. seeing that this was done in 2012, I look forward to seeing where this has gone. Great work.
charl stenger Many thanks; I've posted other videos since that one. - search for mendip89. Additionally, the software is now available as a free download from www.marlbrook.com/download if you would like to try it.
This is a really cool project. It would be cool to study subjects in yoga poses or common stretch positions to make visualisations on how muscles are being targeted in different ways.
There are many research institutions around the world active in the field of biomechanics. Do a bit of background research of your own and then contact one - you never know....
This was linked to in my undergraduate anatomy course! I've done camera tracking before, and some very primitive motion tracking. However, the leaps in technology have already made these tasks quite easy compared to when this video was made. I was wondering if there are any updates on the industry standard for this sort of visualization! To add to this, I'd love to do an analysis on the fine muscles of the neck during different music style performances!
Thanks for sharing the video, if there's any apptionity to tell me the required devices to measure the muscle reaction at different position? also if you know what software required to make simulation for muscle? i know it's a lot, but any word from you will help me to know the true direction.
It looks like the original motion capture data nails the feet down beautifully. Once you hang the skeleton in it the feet seem to slide around but I guess that is just to do with the proses of retargeting the data onto the skeleton. Sorry probably a bit of a dumb question - would be an amazingly useful tool for animators to understand body mechanics. The software looks fascinating.
Thanks for your great question. You are correct in your observation that feet "sticking" to the floor is not guaranteed but is a function of the accuracy of segment lengths used in the biomechanical model. The mocap shown in this video is all based on optical tracking (some other mendip89 videos use inertial tracking) and hence the location of the root segment (the pelvis) is correct but the location of the end effector (ie the foot) is calculated from joint angles and segmental lengths (both of which are subject to errors).

Hello, I'm a Physical Therapist and I'm studying in Master. I would to ask you for advice If I have the camera only 6 and I have to set up the cameras to correcting patient movement walking, running, jumping and sit to stand. If I set the camera like front, back, Left and Right Will be enough? Cloud you please suggest how to set position of camera for walking and running? Thank you.
Pokkate Bandidcharoenlert I know of a motion laboratory which produces excellent results using only 6 motion capture cameras, so it is possible. Without knowing the details of your lab, for example its dimensions, 2 cameras on each side of the runway and one at each end is probably a good start. You will have to establish a compromise between spatial resolution and width of view based on the distance of the cameras from the runway.
Sorry but Joe will have to limp for a little longer. We develop musculoskeletal analysis code which is then used by physiotherapists, biomechanics researchers, surgeons etc.
woaaa didnt know it had so many uses but damn this is AsTOUNDING the amount of use this has to all us humans! How would it work in podiatry im looking at going to a good one in west midlands, to see gait and why my knee joints get worn out after like 20mins walks n stuff!!
Hello, I have a project due on Mechanical purpose, Biomechanical factors & principals, and Overall Performance Objects. The subject I chose was diving. I am having a bit of a time finding computer simulated videos, do you have any in your files that you would be willing to post and I could at the very least look at to give description to or even I could copy the link and use the video on my presentation I can mute the sound so it is just the video and not your words of description. Thank you for the videos they are all very interesting.
Hi there, I have motion capture system in my lab but have no force platform. I want to explore structural steel and welding trades persons task to analyze musculoskelatal injury, where I want to make a model with its ability to calculate not only the loads in all of the muscles of the body but also the loads in the joints of the body. I have captured motion of that task. What other steps I should do? It will be great help if I get answer. Azizur Rahman PhD student
Hi The videos were creating using BoB (Biomechanics of Bodies), which I wrote. BoB is available as a free download from www.marlbrook.com/download (although you will need Matlab).
Eu sou um professor de Educação Física no Brasil gostaria de saber se existe um programa de software para análise biomecânica de lutas de contato, por exemplo, Jiu-jitsu.
oi Cicero A análise biomecânica do contato entre mais de uma pessoa é difícil, pois a medição da força interação pode ser muito difícil. BoB pode realizar a análise, se essas forças de contato são conhecidos ou podem ser modelados.
Yes, it was! It was my dissertation on dancers'balance and visual system. So happy you remembered my name! Look forward to reading more of your work!!

Hi Lisa
The hip joint in BoB is a perfect 3 degree of freedom joint - ie all of the rotational constraints at the joint are released.
This is a really cool project. It would be cool to study subjects in yoga poses or common stretch positions to make visualisations on how muscles are being targeted in different ways.
Good idea Jason, thanks!
Very cool. I would love to be in a study doing that. Biomechanics is really spectacular. :)

Fair enough. :)

How do we differentiate between qualitative biomechanical analysis and quantitative biomechanical analysis ?
Quantitative is numeric whereas qualitative is descriptive.

hey kimberly, good to know you.. is there anyone who is doing a project similar to what you are in tennis? will be of great help .. thanks
has any analysis been done on the effect of taichi movements on body health ?
Tai chi has been analysed........but not by me.
my question is, what force (lb/sq ft) does the foot place on the floor at the beginning of the gait??
It depends on body weight, gait style and how big your feet are!
What's the difference between BoB and OpenSim, that is open source?
The most obvious difference is that BoB is not Open Source.
wow i wanna join. any job there?
Lots of jobs, just no salary.

Where do you get such motion analysis cameras?
How much do they cost?
Dr Abhishek Deo
I use Vicon cameras (www.vicon.com) but other systems are available.
+Dr Abhishek Deo Sorry for the delay in replying (110 months!!!). We purchase our motion analysis cameras from Vicon - see vicon.com
Which software used and which equipment?
I wrote my own software and used various motion capture systems.
