Ankle sprains often lead to a history of recurrent injuries and functional joint instability. This study evaluated a new method for assessing functional impairment in patients with chronic ankle instability.
Case-control study for construct validation purpose.
The participants were tested during one-leg standing for 20 s on an instrumented wobble board and on a balance platform.
Twenty-five young people with previous ankle sprain and an instability score >11 in the "Identification of Functional Ankle Instability questionnaire" and an age-matched control group of 25 healthy individuals.
Wobble board variation of tilt angle measured by two accelerometers placed horizontally in the board.
The variation in angular tilt of the wobble board in the medio-lateral direction (standard deviation of tilt angle) was higher in the group with perceived ankle instability than in the control group: 1.5 (0.7) versus 1.1 (0.3). ICC for intra-tester reliability: 0.87 and correlation with COP area measures from the stable balance platform: 0.64.
People with functional ankle instability display poorer postural stability in the medio-lateral direction when challenged on an unstable surface. The instrumented wobble board may serve as a relevant tool in the clinical evaluation of functional ankle stability.
踝关节扭伤常导致反复受伤史和功能性关节不稳定。本研究评估了一种评估慢性踝关节不稳定患者功能障碍的新方法。
用于结构验证目的的病例对照研究。
参与者在装有仪器的摆动板和平衡平台上进行单腿站立20秒测试。
25名有踝关节扭伤史且在“功能性踝关节不稳定识别问卷”中不稳定评分>11的年轻人，以及一个由25名健康个体组成的年龄匹配对照组。
通过水平放置在板上的两个加速度计测量摆动板倾斜角度的变化。
在感觉有踝关节不稳定的组中，摆动板在内外侧方向的角度倾斜变化（倾斜角度标准差）高于对照组：1.5（0.7）对1.1（0.3）。测试者内可靠性的组内相关系数（ICC）：0.87，与稳定平衡平台上的COP面积测量值的相关性：0.64。
功能性踝关节不稳定的人在不稳定表面上受到挑战时，在内外侧方向上表现出较差的姿势稳定性。装有仪器的摆动板可作为功能性踝关节稳定性临床评估的相关工具。
