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.

On Wednesday, I chaired the symposium "Current and emerging approaches to improving balance and gait in vestibulopathy" with talks from Anissa Boutabla, Klaus Jahn, Andreas Zwergal & Max Wühr, & our own PhD candidate Meichan Zhu, who also presented for the third time in the 3MT final.

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...)

We had the pleasure of hosting 4 different events in our CAREN and University labs, including our workshop "Designing technology-assisted, task-specific protocols for walking experiments, assessments and training", the Motek user meeting and our official ISPGR Lab Tour.

Had a great week in Trabzon, Turkey at #PhysAgeNet 2025! On Thursday, I presented the pilot study of our PhD candidate Liset van der Hulst on fall-resisting skills, followed by a trip to Sümela Monastery where we had some immediate practice!

Really delighted to share the news that I have been awarded the ISPGR Promising Scientist Award! The ISPGR has been my scientific home since my PhD so it's very special to receive this recognition. Also a testament to my many excellent supervisors, collaborators and students over the years!

Glad to report that the statement is back in the Guide for Authors after raising this with the Editor. It was removed by accident when Elsevier was updating the website.
If you are reviewing for Gait & Posture, please ask authors to adhere to this!

No bluesky blue after 20 mins, so I suppose the database is updated periodically. Will check back later.

After joining us about a month ago, today was Tamaya's first presentation for our department about her past research and what she will be working on in the next three years. Very excited to have her here in Maastricht!

Really enjoyed a full day last Friday in Maastricht discussing our past, current & future work using perturbations with Marissa Gerards, Nikita Sharma, Tamaya Van Criekinge & Liset van der Hulst, as well as Pieter Meyns & Kenneth Meijer.
Lots of interesting work to come!
