SUMMARY
Introduction. The dorsiflexion range of motion in the ankle joint within an open kinetic chain can be measured by the First Detectable Resistance Position. Understanding such biomechanical alterations is crucial for intervening in the prevention and expediting the rehabilitation time of these injuries.
Objective. To determine the reliability and concurrent validity of the digital inclinometer as a tool for assessing the First Detectable Resistance Position and the maximum dorsiflexion range of motion in the ankle joint complex.
Methods. The sample comprised 50 healthy and symptomatic participants with Achilles tendinopathy of both genders. All participants had their ankle joint’s First Detectable Resistance Position measured using both a manual goniometer and a digital inclinometer. Data analysis involved descriptive analysis, independent t-test, Intraclass Correlation Coefficient, and Pearson’s Correlation.
Results. The majority of the sample was female (58%), with a mean age of 26.70 ± 10.26 years and BMI (kg/m2) of 25.72 ± 4.52. Intraexaminer and interexaminer reliability Intraclass Correlation Coefficients (ICC) for the digital inclinometer were 0.96 (95%CI 0.94-0.98) and 0.94 (95%CI 0.87-0.97), respectively. The Standard Error of Measurement for digital inclinometer measurements in our study was 0.48° and 0.75° for intraexaminer and interexaminer, respectively. Pearson’s Correlation Coefficient showed a strong direct correlation for Examiner A (r = 0.95; p = 0.001) and Examiner B (r = 0.93; p = 0.001) between the digital inclinometer and the manual goniometer. The Bland–Altman plot showed greater agreement in the digital goniometer when comparing measurements with the manual goniometer for evaluating the First Detectable Resistance Position of the ankle joint complex.
Conclusions. The study achieved excellent reliability and validity with a strong correlation between the manual goniometer and the digital inclinometer for evaluating the First Detectable Resistance Position of the ankle joint complex.
