Looking for a hands-free alternative to traditional crutches? This study investigates the balance adjustments healthy individuals make when first using a single-leg knee crutch. The experiment measured static and dynamic balance in 20 healthy participants before and after a brief practice session with the knee crutch. Results showed a significant impact on balance. Static balance path length nearly doubled, and dynamic balance area was more than halved, with participants favoring their non-crutched leg. These findings indicate a shift to a single-leg stance strategy. Despite these balance alterations, participants quickly adapted to independent ambulation and balance testing using the knee crutch, suggesting a potential for rapid learning and adoption of this mobility device. This research offers insights into postural control and adaptation, informing the design and rehabilitation strategies for knee crutch users.
Published in Perceptual and Motor Skills, this study fits the journal's focus on the relationship between perception and motor behavior. It examines how a new mobility device affects balance and postural control, contributing to the understanding of motor adaptation and learning.
