Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A. The intra-judge reproducibility and the interrater reliability for the different tools used to measure hip extension will be evaluated. Intra-judge reproducibility (photography) and interrater reliability (goniometry and photography) for the different tools used for measuring hip extension will be evaluated.
B. The concordance between EOS measurements and measurements acquired via goniometry and photography will be evaluated.
C. Describe certain radiographic measurements via the EOS system for the four morphotypes

Study Groups

The study population.
Healthy volunteers 20 to 40 years of age.
Intervention: Goniometric measure of pelvic extension reserve. Intervention: Photographic measure of pelvic extension reserve. Intervention: EOS measure of pelvic extension reserve.
Goniometric measure of pelvic extension reserve.
The pelvic extension reserve (°) is measured via goniometry.
The goniometric measurements will be taken once by an investigator on all subjects and once by a different investigator on half of the subjects (with balanced distribution of morphotypes).
Photographic measure of pelvic extension reserve.
The pelvic extension reserve (°) is measured using photography.
Photographic measurements will be performed twice one investigator and 1 time by a different investigator (total of three measurements).
EOS measure of pelvic extension reserve.
The pelvic extension reserve (°) is measured using the imaging system EOS.
Five X-rays will be made for each volunteer on the EOS system. The first is a frontal shot in a bipedal position, reference snapshot for verifying the absence of spinal deformity or hip pathology. The second and third are profile shots, one on the left and one on the right, whole body, bipedal position; serving as a reference picture. The fourth is profile shot, whole body, with the left hip in hyperextension. For maximum left hip hyperextension, the right leg rests on a step of varying height, and the hip is maximally flexed. The fifth is a profile shot, full body, with the right hip in hyperextension. For a maximum right hip hyperextension, the left leg rests on a step of varying height, and the hip is maximally flexed.
