Study Overview
Brief Summary
Currently, there are no validated anatomical landmarks that can be used to predict risk of and diagnose abnormal patterns of pelvic motion.This proposed study will measure sacral slope, pelvic femoral angle and cup ante-inclination in both sitting and standing positions, using healthy individuals without a history of spinal and/or lower extremity pathology. All radiographs will be evaluated for the three measurements by four individuals with the intent of evaluating inter-observer reliability. Determining the reproducibility of these angles between observers will give insight into the potential clinical utility of these measurements in evaluating and treating patients with hip-spine syndrome.
Detailed Description
The purpose of this study is to evaluate the mechanics and influence of spinopelvic motion and balance from normal healthy subjects for the purpose of establishing radiographic measurements which are reliable and reproducible and which could give insight into the potential clinical utility of these measurements as future predictors of who may/may not have spinal pelvic issues and in evaluation and treatment of patients with hip-spine syndrome.
This specific objective of this study will be to measure sacral slope, pelvic femoral angle and cup ante-inclination via radiographs in both sitting and standing positions. The radiographs will be evaluated for the three measurements by four individuals with the intent of evaluating inter-observer reliability.

Outcomes
Primary Outcomes
Intraclass Correlation Coefficient (ICC) for Consistency in Spinopelvic Radiographic Measurements.
Time Frame: At study visit for up to 1 hour
Intraclass correlation coefficient (ICC) was used to assess \[inter-rater/intra-rater/test-retest\] reliability. ICC values range from 0 to 1, where values closer to 1 indicate stronger agreement and values closer to 0 indicate weaker agreement, will be used to evaluate the consistency of the 4 providers in measuring the sacral slope, pelvic femoral angle and cup ante-inclination via radiographs in both sitting and standing positions.
