Abstract:

Purpose: To evaluate accuracy and interexaminer reliability of anterior superior iliac spine (ASIS) positional asymmetry assessment in a pelvic model and to investigate the degree of accuracy seen with varying amounts of ASIS asymmetry when evaluated from different sides of the model. Methods: Five osteopathic physicians and 5 osteopathic predoctoral fellows evaluated ASIS asymmetry of 13 randomized settings on a pelvic model first from the right side and then from the left on 2 separate days. Assessment occurred in pairs for physicians and a group of 5 for fellows. One minute was allowed for evaluation of each setting. Results: Physicians and fellows were more accurate from the right side of the model (kappa=0.56 and kappa=0.52, respectively). Average interexaminer reliability was greatest from the left side of the model for physicians and right side for fellows (physicians kappa=0.46; fellows kappa=0.37, respectively). Conclusions: The development of a novel, pelvic model allowed assessment of interexaminer reliability and accuracy of ASIS asymmetry assessment. As the amount of asymmetry increased, accuracy of assessment increased from each side of the model. Interexaminer reliability reached values that can be considered clinically significant in the physician group; however, the amounts of asymmetry in the methodology may be higher than amounts of asymmetry observed in clinical practice. Further experimentation is needed to explore the use of a model when developing skills of bony anatomic landmark asymmetry assessment.
