Accurate assessment is essential for tailoring effective rehabilitation programs. This study aims to evaluate the concurrent validity and test-retest reliability of Analiz Sistem and Sensor Medica pedobarographic devices in assessing plantar pressure distribution under static postural conditions in individuals with CAI.
Method: A total of 64 participants with unilateral CAI were included, with diagnoses confirmed via a Cumberland Ankle Instability Tool (CAIT) score of ≤24. Static postural assessments focused on surface area and impulse parameters for rearfoot, midfoot, and forefoot regions. Measurements from both systems were analyzed for agreement using Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM), paired t-tests, and Bland-Altman plots.
Results: ICC values ranged from 0.80 to 0.99, demonstrating good to excellent reliability. Rearfoot metrics showed the highest reliability, with ICC values exceeding 0.94. SEM values were consistently low (<1.5 for most metrics), indicating high measurement precision. Paired t-tests revealed no significant differences between the two systems (p>0.05). Bland-Altman plots confirmed narrow limits of agreement and minimal mean bias across all metrics.
Conclusion: Analiz Sistem and Sensor Medica offer accurate and reliable measurements of plantar pressure distribution under static conditions. Their portability and cost-effectiveness make them suitable for clinical and field-based environments. Future research should focus on integrating advanced technologies like artificial intelligence to enhance their utility further.}, number={26}, publisher={İstanbul Gelişim Üniversitesi}
