Modified Stabilization Test to Diagnose Chronic Syndesmotic Injuries Based on Posture Control

Area of Science:

• Orthopedics
• Sports Medicine
• Diagnostic Imaging

Background:

• Chronic syndesmotic injuries often present diagnostic challenges.
• Accurate diagnosis is crucial for effective patient management and treatment.

Purpose of the Study:

• To propose and validate a novel, noninvasive method for diagnosing chronic syndesmotic injuries.
• To compare the diagnostic efficacy of the proposed method against established imaging techniques.

Main Methods:

• The Modified Stabilization Test was developed, combining center of pressure and sensory organization tests to assess postural control.
• Diagnostic accuracy was evaluated in 16 patients with chronic ankle instability.
• Radiography, CT, MRI, and arthroscopy were used for comparative analysis.

Main Results:

• The Modified Stabilization Test demonstrated high sensitivity (100%) and specificity (87.5%) for diagnosing chronic syndesmotic injuries.
• The test achieved a superior Area Under the Curve (AUC) of 0.906 compared to imaging indices (AUC 0.516-0.891).

Conclusions:

• The Modified Stabilization Test is a validated, noninvasive tool for screening chronic syndesmotic injuries.
• This test offers a more accurate and effective diagnostic approach compared to current imaging modalities.
