Introduction: It is believed that poor alignment of the lower extremity (e.g. pes planus [flat feet] or genii valgum [knock knees]) can lead to injury. Data reporting different methods of alignment measurements involving the hips, knees and ankles in runners, football players and the military, have being investigated for decades and consisted of photographs, X-rays, measuring alignment using tractographs or goniometers and visualisation. Method: To develop a battery of tests for a prospective study, a pilot study to investigate the reliability of lower extremity measurements of 10 participants was undertaken. The measurements consisted of photographs taken in the frontal plane and medial and lateral sides of the lower extremity in the standing position with markers placed on bony prominences from the hip to the malleoli. Actual measurements (lengths or angles) were obtained from calculations using the x and y coordinates of each variable such as the Q-angle, leg length, knee varus/valgum and hyperextension. Other measurements were the foot posture index (6-point scale) and ankle dorsiflexion (lunge test). Data collection of each participant was performed twice and averaged to be used in the analyses. All measurements were re-collected a week later by the same researcher to test for reliability. Results and discussion: It was found that the measures used had strong intrarater reliability across all variables. The intraclass correlation coefficient (ICC) had a range of 0.95–0.99. The results are an indication that standardised methods using 2D analyses is more beneficial and reliable and will aid in future studies.
