ABSTRACT
OBJECTIVES:
To determine the inter-rater reliability and criterion validity of two-dimensional (2D) measures of ankle function in the sagittal plane for participants with Achilles tendinopathy (AT).DESIGN:
Cohort study.SETTING:
University Laboratory, Participants, Adults with AT (N = 18, Women 72.2%, Age = 43.4 ± 15.8 years, BMI = 28.7 ± 8.9 kg/m2) MAIN OUTCOMEMEASURES:
Reliability and validity were determined with intra-class correlation coefficients (ICC), standard error of the measurement (SEM), minimal detectable change (MDC), and Bland-Altman plots for ankle dorsiflexion and positive work during heel raises.RESULTS:
Inter-rater reliability between three raters for all 2D motion analysis tasks was good to excellent (ICC = 0.88 to 0.99). Criterion validity between 2D and 3D motion analyses for all tasks was good to excellent (ICC = 0.76 to 0.98). 2D motion analysis overestimated ankle dorsiflexion motion by 1.0-1.7° (3% of mean sample value) and positive ankle joint work by 76.8 J (9% of mean) compared to 3D motion analysis.CONCLUSION:
Although 2D and 3D measures are not interchangeable, the good to excellent reliability and validity of 2D measures in the sagittal plane support the use of video analysis to quantify ankle function for individuals with foot and ankle pain.Palabras clave
