Hello,
The published paper showing the capabilities of OpenCap (https://pubmed.ncbi.nlm.nih.gov/37856442/) showed that the system could measure kinetic asymmetries in squatting. However, the data collected in this study were all performed on healthy individuals. How the system would perform if the subject had actual strength deficits on one side, such as in hemiparesis? Would we need to do additional scaling of optimal muscle forces to get accurate kinetics?
Thank you!

Re: Inverse Kinematics with Strength Asymmetries
Hello,
That's a good question. I'm guessing if the strength deficits result in kinematic asymmetries, then this might be reflected in the kinetics. However, it would indeed be beneficial to incorporate some knowledge about the patient into the model. For instance, researchers have used data from dynamometry to get a sense of force capabilities and scale muscle force properties accordingly.
Best,
Antoine
