| Abstract |
Objective
This study was designed to evaluate the effect of ankle bracing (Aircast) on postural sway and limb load asymmetry (LLA) in normal adults.
Method
263 healthy subjects volunteered. These subjects were performed the balance test on three different conditions, 1st test fulfilled without ankle brace, 2nd test with aircast on one ankle and 3rd test with aircast on the other ankle. All subjects were divided into two groups; younger(＜65 years) and older (≥65 years) group. Postural sway and body weight distribution were recorded while the subjects were standing on two adjacent force platforms during 30 seconds trial. All subjects chose a comfortable stance with feet apart and asked to look straight ahead at a fixed point in a quiet room.
Results
There were significant differences not only in LLA but also in postural sway between younger and older group. The difference of postural sway and LLA in older group was more prominent that in younger group (p＜0.05).
Conclusion
The results indicated that ankle bracing improved postural sway irrespective of age. Moreover in older group, ankle bracing on one ankle that was in the absence of LLA improved postural sway by far. (J Korean Acad Rehab Med 2006; 30: 508-512) |
