Purpose Spectacle non‐tolerance or adverse events to spectacle wear are serious concerns
for both patients and practitioners. Non‐tolerance may contribute to a negative impact on the …

Accurate control of posture, balance, and locomotion through the environment involves a
coordinated set of sensorimotor processes that continually encode and compare information …

Objective To determine whether the provision of single lens distance glasses to older
wearers of multifocal glasses reduces falls. Design Parallel randomised controlled trial …

This chapter will review current theories of how adults use vision to guide adaptations to the
basic locomotor rhythm in order to cope with environmental demands, eg to step over an …

Background Falls sustained when descending stairs are the leading cause of accidental
death in older adults. Highly visible edge highlighters/friction strips (often set back from the …

Purpose. To determine the relative importance to adaptive locomotion of peripheral visual
cues provided by different parts of the visual field. Methods. Twelve subjects completed …

Background. Trips are the largest contributor to falls in older people, yet little is known about
the underlying physiological mechanisms for safe obstacle negotiation. The aims of the …

Background Tripping is a common factor in falls and a typical safety strategy to avoid tripping
on steps or stairs is to increase foot clearance over the step edge. In the present study we …
