“…The specific procedures for the three-dimensional motion analysis have been previously reported. 11 A double-sided skin tape (Optitrack, Inc., Corvallis, OR, USA) was used to adhere 14 mm retroreflective markers bilaterally to the following locations: anterior superior iliac spine, posterior superior iliac spine, lateral thigh (cluster of four markers), medial femoral epicondyle, and lateral femoral epicondyle (Figure 3). Marker trajectories were collected at 240 Hz using 14 Vero v2.2 cameras (Vicon Motion Systems Ltd, Oxford Metrics, UK) and filtered using a lowpass Butterworth filter with a cutoff frequency of 10 Hz.…”

Objective The Posterior Standing Overhead Arm Reach (SOAR) test has been previously reported as a reliable clinical measure of closed chain hip extension motion. The proposed Medial SOAR test expands on that testing approach to provide a similar measure of functional hip adduction motion. This was a preliminary intrarater and interrater reliability and validity study of the Medial SOAR test as a measure of functional hip adduction. Design Cross-sectional. Setting University motion analysis laboratory. Participants Fifty hips were assessed in 25 (22 female) asymptomatic participants (mean age = 23.4 years, SD = 0.8). Main measures Maximum hip adduction during the Medial SOAR test was measured with a standard goniometer independently by two examiners. The test was also performed using three-dimensional motion capture. The intrarater and interrater reliability of the goniometric measure was determined using intraclass correlation coefficients, and the relationship between measures obtained via goniometry and three-dimensional motion capture was assessed with Pearson correlations and Bland–Altman analysis. Results Intrarater reliability (ICC2,3) was 0.88 (95% CI = 0.80–0.92) for Examiner 1 and 0.87 (95% CI = 0.79–0.92) for Examiner 2. The standard error of measurement and minimal detectable change were less than 3.0°. Interrater reliability demonstrated an intraclass correlation coefficient = 0.62 (95% CI = 0.28–0.79). Pearson correlations were significant with low-to-moderate associations (r = 0.49, P < 0.001; r = 0.24, P = 0.045). Conclusions Similar to the previously reported Posterior SOAR test, the Medial SOAR test demonstrated acceptable intrarater and interrater reliability, along with low-to-moderate associations with three-dimensional motion capture. The Medial SOAR test has the potential to provide a reliable and accurate assessment of closed chain hip adduction.
