Table 4.

Femoral elevation angles (degrees) at the start and at peak exertion for each direction of exertion and ascribed hip angle. Standard deviation of the means is represented in parentheses. Italicized values are the adjusted p-values for post hoc paired comparisons of means corresponding to statistically significant interactions between exertion direction and time (initial, peak). Shaded cells represent potential paired comparisons that were not performed.

The following is an example for reading the table: For an ascribed hip abduction angle of 10 degrees, there was no difference in the femoral elevation angle at the start of the exertion (p = 0.402) and a statistically significant difference at peak exertion (p < 0.001). A statistically significant reduction in the femoral elevation angle occurred between the start and peak of adduction exertions (p = 0.002) and a statistically significant increase during abduction exertions (p = 0.001).
