Hypothesis
Can a visual illusion increase the perceived height of a step and lead to safer stepping behavior?
Conclusion
The study found that a visual illusion can increase the perceived height of a step, resulting in safer stepping behavior with greater foot clearance.
Supporting Evidence
- Subjects perceived the step to be higher in the V configuration compared to the H configuration.
- Maximum toe elevation changed significantly corresponding to the size of the visual illusion.
- There were highly significant associations between perceived step height and maximum toe elevation.
Takeaway
The way we see things can trick our brain into thinking a step is higher, which helps us lift our feet higher and avoid tripping.
Methodology
The study involved 21 young, healthy subjects who performed stepping tasks while their perceived step height and toe elevation were measured under different visual conditions.
Limitations
The study's findings may not generalize to older adults or individuals with balance issues.
Participant Demographics
21 young adults (10 males and 11 females, mean age 28.2 years)
