#biomechsky question. Is there a way to plot opensim models/kinematics/ whatever native from python? That is, without opening an opensim window, can I plot a vsiualisation of my results of the sim? If not, why not? And would you be interested in it?

And another preprint. This time with Simone Berkelmans and @maartenafschrift.bsky.social Foot placement is not controlled based on angular momentum. Bold title; hope it stands up to your scrutiny! As always; feedback and comments more than welcome! www.biorxiv.org/content/10.6...

Foot placement is not controlled based on angular momentum

This study examined how mediolateral foot placement is controlled following mechanical perturbations that affected either whole-body linear or angular momentum. Predictive foot placement models based ...

And another preprint, this one from our STEPUP consortium: "Foot placement coordination is impaired in people with Parkinson’s Disease". Too many authors to tag! www.biorxiv.org/content/10.1... feedback welcome!

Foot placement coordination is impaired in people with Parkinson’s Disease

Background Gait instability is a common and disabling symptom of Parkinson’s disease (PD), contributing to frequent falls and reduced quality of life. While clinical balance tests and spatiotemporal g...

New preprint by Yiyuan Li, with @jvandieen.bsky.social and others; The contribution of vestibular and proprioceptive signals to trunk stabilization varies between postural tasks and between walking speeds. www.biorxiv.org/content/10.1... feedback welcome!

The contribution of vestibular and proprioceptive signals to trunk stabilization varies between postural tasks and between walking speeds

Stabilizing the upright posture of the trunk relies on vestibular and proprioceptive afference. Previous studies found that the feedback responses to sensory afference vary between postures and tasks....

Ok, sky help me out here. If doing inverse kinematics using IMUs, is really only the orientation of the sensors used? It would seem that if you have a reasonable estimate of pos of sensor on segment, given kinematic chain, you would also know acc, and hence, could use that info for better fit. 1/2

Have free living lower back IMU data, and want to identify gait? Check out new preprint by Yuge Zhang; "An open-source, externally validated neural network algorithm to recognize daily-life gait of older adults based on a lower-back sensor". www.biorxiv.org/content/10.1.... Feedback welcome!

An open-source, externally validated neural network algorithm to recognize daily-life gait of older adults based on the lower-back sensor

Background Accurate gait recognition from daily physical activities is a critical first step for further fall risk assessment and rehabilitation monitoring based on inertial sensors. However, most ope...
