My personal summary - poor reporting and lacking justifications of protocol choices is currently holding this sub-field of fall prevention back. In many cases, it seems that pragmatic decisions are made but there is a reluctance to report these as such or that the researchers don't have ...

New paper out on @openmindjournal.bsky.social *

I propose balance is a core biophysical self-regulatory function, organisationally akin to thermo-regulation. Might seem radical off the bat, but by the end of the paper I hope you'll agree it seems pretty obvious.

But the editors can just publish a short editorial highlighting the guidelines for their readership. They don't need to duplicate-publish the full guidelines paper, do they?

Can anyone point me to an explanation/justification why certain reporting guidelines need to be published in multiple journals simultaneously? I get annoyed by the practice every time I need to cite one.
PS - the "need" to reach a wider audience is not relevant in the age of open access publications

The implication of this might be that using self-perceived stability to assess the intensity or progression of training is inaccurate.

New preprint from our PhD candidate Liset, describing results that guided key choices in our upcoming trial of fall-resisting skills training for older adults.
One key finding: older adults' perceptions of their stability during perturbations does not align with expert observations!

Abstract
Objectives
Dynamic visual acuity (DVA) can be assessed on a treadmill while walking at different speeds and is used to assess people with bilateral vestibulopathy (BVP). However, the effects and interactions of age, BVP, and walking speed on DVA loss and assessment dropout are unclear. Our objective was to investigate the effects of BVP, age, and walking speed on DVA loss and assessment dropout in participants with BVP and healthy age–sex-matched participants.

Methods
41 participants with BVP and 41 age–sex-matched healthy participants completed a treadmill-based DVA assessment, including a static condition at 0 km/h and walking conditions at 2, 4, and 6 km/h. DVA loss was measured as the visual acuity difference between static and walking conditions. The drop-out rate, handrail use, and DVA loss were examined in relation to BVP, age, and walking speed.

Results
Age significantly increased the odds of dropping out (odds ratio = 1.160, p < 0.001), while BVP did not increase the odds of dropping out (odds ratio = 0.792, p = 0.733). A significant Group*Speed (p = 0.004) interaction effect was found for DVA loss, with DVA loss being significantly worse in people with BVP across all walking speeds, getting progressively worse as speed increased, which was not seen in the healthy participants. Age did not have a significant effect on DVA loss (p = 0.06).

Conclusion
BVP does not appear to restrict the ability to walk at the higher speeds of a DVA assessment and cause an increase in dropout rate, whereas age does. BVP significantly impacts DVA, with increasing impact at increasing walking speeds.
