Abstract: "The objective of this study was to determine whether a landmark protocol could reliably gather more anatomically accurate data than the default software setting for an electromagnetic tracking system. Nineteen healthy participants (10 males, 9 females) were measured clinically for pelvic angle (deg), tibiofemoral angle (deg), and navicular drop (mm) and compared to kinematic variables of transverse knee angle, frontal plane knee valgus/varus angle, and sagittal plane pelvic angle obtained from both the default and landmark digitization protocols (counterbalanced). Day-to-day reliability for both digitization protocols ranged from an ICC of -0.44(9.5 degrees) to 0.72(2.3 degrees). Kinematic values obtained from the landmark protocol were generally larger and more variable than those obtained from the default setting, and tended to correlate better with the clinical measures of anatomical alignment. While further study is needed, the landmark protocol shows promise as a method for collecting kinematic data that more closely approximates anatomical alignment of the lower extremity."--Abstract from author supplied metadata.
