Record snowfall in Erlangen required us to be creative with our study participants. Its stability was above average, the speed not so much.

It’s a personal preference. I was once asked to combine two bracketed phrases in the same sentence into one.

Anne Koelewijn @drannek.bsky.social · 04/03/2025

For sagittal plane movements, the orientation of the axis perpendicular to the plane can probably be estimated from the movement itself rather than special calibration movements. For 3D movements, I’m not sure. A direct optimization or ML model might work, but should be developed and tested first.

100

Anne Koelewijn @drannek.bsky.social · 04/03/2025

So yes! (Should have answered both messages at the same time). It depends on your definition of assuming but we measure the position (with a scale or with a marker on the IMU) and estimate the alignment using the gravity direction and calibration movements (in the sagittal plane “only”)

010

Anne Koelewijn @drannek.bsky.social · 04/03/2025

Yes, you could even do that without using orientation data and use the optimization to find the optimal alignment and orientation estimation. We did this with a machine learning approach and it worked quite well for the position. We’re still working on that publication.

010

Anne Koelewijn @drannek.bsky.social · 04/03/2025

We use the acceleration, angular velocities, and position and orientation of the sensor on the body segment but do not use IK. I think that you probably do not need the information very precisely if you have a musculoskeletal model for IK since the model limits the motion to reasonable ones.

Our paper on sparse sensorsets was published: www.frontiersin.org/journals/bio...! Happy to get it out after many private and professional challenges. We show that as long as there are IMUs on the feet and the thighs/pelvis, simulations are similarly accurate as with a full lower leg IMU setup.

Good question! We use it to simulate gait by solving optimal control problems. We can predict new movements, for example to investigate exoskeleton controllers, and reconstruct from marker, force, and/or inertial measurements. More details in the paper submitted to JOSS, which is in the repository.

Our paper was published! When combining biomechanics datasets for ML training, bias might be introduced. We show that ML models can identify dataset source really well. Thus, training on multiple datasets can lead to identifying the source instead of data characteristics: dl.acm.org/doi/pdf/10.1...

New preprint! We trained a neural network on dynamic muscle force recordings and showed that it can better estimate muscle forces than a Hill model. This is a first step towards more accurate muscle force estimations in human simulations as well, but a long ways to go. #biomechsky
