Overview
In a recent study conducted by the Ball State Biomechanics program, researchers examined how different types of ankle support impact the way people walk and climb stairs. The study compared two ankle support devices: the TayCo Brace (XAB) and an orthopedic walking boot (OWB), with participants also walking in regular shoes (Shod) for comparison.
Key Finding
TayCo XAB is 96% as stable as a walking boot in a kinetic state, and does not affect the knee and hip in the same way as walking boot.
Walking Findings
When it came to walking on level ground, both the XAB and OWB significantly reduced ankle motion compared to walking in regular shoes. Interestingly, there was no statistical difference in ankle motion between the two support devices, except in the sagittal plane (up-and-down motion), where the XAB allowed slightly more movement than the OWB.
Key Point: Both the XAB and OWB effectively controlled ankle motion during walking, with slight differences in ankle flexibility between the two.
Stair Climbing Results
During both ascending and descending stairs, ankle motion was significantly reduced when wearing either the XAB or OWB compared to regular shoes. However, the XAB allowed slightly more ankle flexibility during stair descent compared to the OWB. Additionally, the study found differences in knee and hip motion depending on the support device and age group.
Key Point: Both the XAB and OWB limited ankle motion during stair climbing, with the XAB offering a bit more flexibility during descent. Knee and hip motion were also affected, with differences observed between age groups.
Overall Insights
Overall, the study showed that both the XAB and OWB effectively controlled ankle motion during walking and stair climbing. However, there were subtle differences between the two devices, particularly in ankle flexibility during stair descent. Additionally, knee and hip motion varied depending on the support device and age group.
While both ankle support devices were effective, slight differences were observed in ankle flexibility and knee/hip motion. Age also played a role in how participants adapted to the support devices during movement.
In conclusion, this study provides valuable insights into how ankle braces can impact walking and stair climbing, offering valuable information for both healthcare professionals and individuals considering the use of such devices.
