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.

What a week it was at #ISPGR2025 last week!

It was really special to have so many amazing colleagues productively interacting in our city (with encouragement from @melvynroerdink.bsky.social)! Thanks to all involved in the planning and organisation @ispgr.bsky.social and all who attended!

A personal career highlight came for me on Tuesday with my talk as the ISPGR 2025 Promising Scientist!
Directly followed by a busy poster session where I shared the results of a project conducted in Toronto with @avrilmansfield.bsky.social (preprint: www.biorxiv.org/content/10.1...)
