Background: Three dimensional motion analysis systems and goniometer measurement are often analyzed in relation to each other in biomechanical science, although the correlation between the methods are not well researched. Aim and purpose: To investigate the criterion validity between physical examination of lower extremity using a goniometer with a three dimensional motion analysis system. Method: Six healthy participants (12 lower limbs) were recruited. The variables of interest were passive hip internal and external rotation, knee joint extension, static knee valgus, internal and external tibia rotation, bimalleor angle and ankle dorsal flexion range of motion. Measurements were collected with goniometer and a three dimensional motion analysis system. A modified Helen Hayes marker set was used and the physical examination was made by two physiotherapists using conventional testing positions. Spearman’s rank correlation coefficient and Bland Altman plot were used to describe correlation and level of agreement, respectively. Results: Hip external rotation (rs=0.97), BMA (rs=0.96) and hip internal rotation (rs=0.89) showed acceptable and significant correlation (p<0.01). Tibia internal rotation (0.60, significant p<0.05), ankle dorsiflexion (rs=0.56 p>0.05) tibia external rotation (rs=0.50 p>0.05) knee valgus (rs=-0.16 p>0.05), knee extension (rs=-0.20 p>0.05) did not correlate. Conclusion: The criterion validity were good between the measurements for hip external and internal rotation and BMA. Criterion validity could not be described for the other measurements.
