AKE = active knee extension test; PSLR = passive straight leg raise test. VSR = V-sit and reach test. FFD = finger-to-floor distance test.
Indicates statistically significance correlation at p≤0.05.
Dysfunction for each group was identified based on the a priori cut points based on the best available literature, as described above. For example, the “dysfunctional PSLR group” included all participants who demonstrated dysfunction on the PSLR test. A priori definitions for dysfunction were as follows: AKE greater than 20 degrees; PSLR less than 80 degrees; VSR inability to reach “zero” line; and FFD inability to reach edge of box.
