For anyone who had tried already our workflow for creating personalised OpenSim (JAM) models of the knee joint and struggled with installation - I have just pushed an update to the repository updated the code and installer for Python3.8 and OpenSim 4,3 - Check it out and Reach out !
and which do you think the boundary is higher ?
Point wise difference in surface geometry of the reconstructed femoral mode 3. Heat map indicates the extent of local anatomy variation in relation to increasing age.
Osteoarthritis (OA) is known to cause changes in bone shape. Katherine Nguyen & coauthors found that CT-based shape modelling reveals age-related bone shape changes even in knees without OA. Read (open access) in the Journal of Orthopaedic Research: https://buff.ly/4i1wJ46 #ORSSMC #orthoImaging
Our recently published paper in Foot & Ankle Clinics discusses the increased utilization of weightbearing CT and biplane fluoroscopy in the foot and ankle and the lack of standardization of 3D measurements for these applications.

population based approaches like SSM, PCA, synergy analysis etc combined with more accurate and validated insilico models seems to be an exciting opportunity to do so in the future
Been seeing a lot more studies investigating the association between morphology/alignment and function in recent months/years. Wondering what the threshold for being able to actually directly define direct causation is/will be.
I'm happy to share the pre-print for the Neuromusculoskeletal Modeling (NMSM) Pipeline. The pipeline is built on top of OpenSim and encompasses seven tools for personalizing models and design treatments using optimal control

We've got lots of awesome PhD projects on offer in the School of Mechanical, Aerospace and Civil Engineering,@sheffielduni.bsky.social to start in Oct 25 www.findaphd.com/phds/school-...
A really cool visualisation of the work we done at

HI Jason - me again - I read the relevant sections. Am I correct in saying that "dynamic" in this case refers to variability ? So it is that there would be less pronounced peaks/troughs and instead closer resemle a "flat line" ? An interesting concept - and looking forward to diving in a bit more
Couldn't agree more!
This is also why I am not one to jump on the " oh it's publish in XXXX journals so it's bad". I'm sorry to say I've seen papers I consider great in these journals and papers in "flagship" journals I consider horrible.
Thanks for the link - will check it out !
Currently interested in transitioning my research from pure lab based to clinic applications and practice.
Combining population , and in silico models with machine learning to (try to) make real world impact
Short intro:
Movement scientist by training but moved towards computer simulation in my PhD, currently a Postdoc. Working with; statistical shape modeling, image based models, personalised knee and ankle models, out of lab motion capture and modelling, predictive sims, knee OA, ACLr and many more.
Hi Jason - curious what you mean by "less dynamic TF joint contact loading " - here dynamic refers to just during walking or ?
staying on both unless the other sight really dies off and not just people saying it is "dying"
If you locked the Pelvis X translations and increased the speed it would look somewhat like irish dancing. I have a bunch of simulations that resemble this and worse - I keep some to give myself a laugh when I feel like throwing my PC out the window

Huge Congratulations Claire !
In theory some EMG informed approaches, assuming you can get decent signals in such a high speed task - would be my first point of call. Otherwise I have seen some other matlab based solvers where you can try and enforce these cocontractions but might be overkill here. Still super cool work
Sometimes with a little help but that is, in my view, the advantage of doing it this way. Force them to be direct, succinct, but more Importantly to be able to convey something complex easily - especially if they are number 5/5 and already fried 😂
Every fornight I have ~2.5hour meeting w/ 5 researchers (15min/pp) I supervise/oversee - from ankle, knee, shoulder, and incap research ; Masters - PhD - and postdoc level. Simultaneously one of the most rewarding but draining exercises - having to swtich between each very differnt project
In case anyone has already downloaded the repository - I pushed a new commit this morning becuase I forgot to upload one dependent module ( :
If I look at your normalised forces which I guess is more or less equivalent to activation (depending if you ignored force-len/vel in osim) - they seem quiet low for such a task. Curious on your thoughts
Hi Mark - super interesting paper. Im curious on a few things - primarily - the use of static optimisation (SO) approach - presumably there is alot of co-activation (both agonistic and antagonistic happening during such a task - do you think you miss something with using SO here ?
A reminder - check in on your colleagues - ask how they are doing. We spend so much time together in our offices and meetings its easy to be apothetic. Just because someone doesnt look like they are struggling doesnt mean they arent

Not a perfect analogy or advice but some broad strokes good points - in academia we are doing "knowledge work" - not manufacturing - don't measure your productivity by number of tasks done.
