To propose and validate a modified noninvasive method for the diagnosis of chronic syndesmotic injuries.
This study included 16 patients with chronic ankle instability. Herein, we propose the Modified Stabilization Test, a new measurement for use in the diagnosis of chronic syndesmotic injury, as determined by wearing a 60-kPa pneumatic brace. The test combines the center of pressure and sensory organization test to measure postural control. For comparison, we also measured the tibiofibular clear space, tibiofibular overlap, and medial clear space using anteroposterior radiograph; a line marked horizontally above the tibial plaque using computed tomography (CT) to measure the syndesmotic gap and fibular rotation angle; and magnetic resonance imaging (MRI) scans to determine the presence of the λ sign. The distance of syndesmosis was confirmed in 16 individuals through arthroscopy, and the results of the examination were used to determine the diagnostic efficacy of each index.
Receiver operating characteristic curve analysis revealed that the optimal cut-off value, sensitivity, and specificity of the Modified Stabilization Test for the diagnosis of chronic syndesmotic injuries were 0.80, 100%, and 87.5%, respectively. The area under the curve (AUC) of the Modified Stabilization Test was 0.906 (95% CI 0.656, 0.993; < .001), which was superior to imaging indices such as radiography, CT, and MRI (AUC = 0.516-0.891).
We developed the Modified Stabilization Test-a noninvasive diagnostic tool for the screening of chronic syndesmotic injuries. The test showed high sensitivity and specificity for the identification of chronic syndesmotic injuries and is helpful in the identification of chronic syndesmotic injuries.

提出并验证一种改良的无创方法，用于诊断慢性下胫腓联合损伤。
本研究纳入 16 例慢性踝关节不稳定患者。在此，我们提出改良稳定试验，这是一种新的测量方法，用于诊断慢性下胫腓联合损伤，方法是使用 60kPa 气动支具。该测试结合了压力中心和感觉组织测试，以测量姿势控制。为了比较，我们还使用前后位 X 线片测量胫腓骨间隙、胫腓骨重叠和内侧间隙；使用 CT 测量胫骨斑块上方的水平线标记的线来测量下胫腓联合间隙和腓骨旋转角度；并使用 MRI 扫描确定 λ 征的存在。通过关节镜确认 16 例个体的下胫腓联合距离，检查结果用于确定每个指标的诊断效能。
受试者工作特征曲线分析显示，改良稳定试验诊断慢性下胫腓联合损伤的最佳截断值、敏感性和特异性分别为 0.80、100%和 87.5%。改良稳定试验的曲线下面积（AUC）为 0.906（95%CI 0.656，0.993；<0.001），优于影像学指标，如 X 线、CT 和 MRI（AUC=0.516-0.891）。
我们开发了改良稳定试验，这是一种用于筛查慢性下胫腓联合损伤的无创诊断工具。该测试对慢性下胫腓联合损伤的识别具有较高的敏感性和特异性，有助于识别慢性下胫腓联合损伤。
