Visually-impaired risk falling by stepping higher and more slowly over objects
People with vision impairment are more cautious when stepping over obstacles when walking – but increase their risk of falls, according to a new study published in the journal Scientific Reports.
Researchers at Anglia Ruskin University (ARU) asked participants with simulated blurred vision to negotiate a 10cm-high obstacle on the floor under increasing time pressure. The way they negotiated the obstacle was recorded, as was their gaze.
The results showed people with impaired vision lifted their lead foot 43% higher and 10% slower over the obstacle than the control group, even when walking 20% faster. However, this pronounced gait was observed to affect their stability.
The group with vision impairment showed 32% more anxiety than the control group irrespective of time pressure. They also looked down more frequently and for longer when approaching the obstacle.
