Fall rates in bifocal, trifocal, and progressive addition lens glasses wearers.

Purpose: There is evidence that wearing multifocal glasses increases the risk of falls in older people, especially when walking on stairs and in unfamiliar settings. However, it is not clear whether all types of multifocal glasses are equally associated with falls. This study comprised a secondary analysis of data from the VISIBLE randomized controlled trial to determine whether fall rates differ among older bifocal, trifocal, and progressive addition lens glasses wearers.

Daily-life walking speed, running duration and bedtime from wrist-worn sensors predict incident dementia: A watch walk - UK biobank study.

Objective: To determine if wrist-worn sensor parameters can predict incident dementia in individuals aged 60 + years and to compare prediction with other tools.

Design: Observational cohort study.

Setting: Community PARTICIPANTS: The cohort comprised 47,371 participants without dementia, aged 60 + years, who participated in the UK Biobank study (mean age=67 ± 4 years; 52 % female).

Critical behavioral traits foster peer engagement in Online Mental Health Communities.

Online Mental Health Communities (OMHCs), such as Reddit, have witnessed a surge in popularity as go-to platforms for seeking information and support in managing mental health needs. Platforms like Reddit offer immediate interactions with peers, granting users a vital space for seeking mental health assistance. However, the largely unregulated nature of these platforms introduces intricate challenges for both users and society at large.

Treadmill belt accelerations may not accurately replicate kinematic responses to tripping on an obstacle in older people.

Background: Treadmill belt perturbations have high clinical feasibility for use in perturbation-based training in older people, but their kinematic validity is unclear. This study examined the kinematic validity of treadmill belt accelerations as a surrogate for overground walkway trips during gait in older people.

Methods: Thirty-eight community-dwelling older people were exposed to two unilateral belt accelerations (8 m s-2) whilst walking on a split-belt treadmill and two trips induced by a 14 cm trip-board whilst walking on a walkway with condition presentation randomised.

Virtual reality obstacle avoidance training can be enhanced by physical feedback via perturbations: A proof-of-concept study.

Background: Fall injuries resulting from trips are a major health concern. Virtual reality (VR) offers an effective way of training obstacle avoidance while walking due to its ability to provide safe and meaningful real-time feedback during rehabilitation. This proof-of-concept study examined the benefit of providing physical feedback during obstacle avoidance gait training using VR.
