520 $a Research in sports medicine has focused on identifying the risk factors that tend to increase the risk of knee injury in females compared to males.
520 $a The purposes of these studies are to (1) compare the effects of gender on lower extremity alignment, (2) compare the effects of gender on lower extremity kinematics during 3 functional tasks, (3) to examine the relationships between lower extremity alignment and kinematics, and (4) to compare groups of extremes of alignment to an alignment group in a middle range in regards to lower extremity kinematics.
520 $a For Study #1, a comparison of gender and lower extremity alignments was performed to ensure that the sample population demonstrated alignment patterns similar to commonly accepted gender differences. A comparison of males and females was then made to examine the effects of gender on the specific kinematic measures listed above. Statistical analysis revealed that there was a gender difference for the measures of lower extremity alignment. Females demonstrated greater q-angle, genu recurvatum, and femoral anteversion compared to males. There was no difference between males and females for navicular drop, tibial varum, or pelvic tilt. For the analysis of the effect of gender on lower extremity kinematics, there was a single, significant kinematic descriptor for each of the three functional tasks. All 3 significant kinematic variables were related directly to hip motion.
520 $a For Study #2, relationships between lower extremity alignments and kinematics were evaluated. Bivariate correlations were performed to analyze for these associations. A second analysis compared the extremes of alignment to a middle range of alignment for effect on lower extremity kinematics during the 3 tasks. This was an attempt to identify if the significant relationships as observed in the correlational analysis would be revealed as significant differences between groups of lower extremity alignment. Though there were significant correlations between certain lower extremity alignments and kinematics, a majority of the significant correlations were relatively small with most alignments explaining less than 30% of the variance of any of the kinematic measures. No correlational trends were directly confirmed when each lower extremity alignment was divided into thirds of least, middle, and greatest degree of alignment. (Abstract shortened by UMI.)
