Therefore, clinically different cut-off values need to be estab-
lished in order to detect short hamstring flexibility from SRT and TT
test methods. Kappa agreement between PSLR and SRT was found
to be moderate (k ¼ 0.45). Slightly lower results were found by
Davis et al. (2008), who reported that SRT and PSLR had a kappa
agreement of 0.39. Perhaps a possible explanation for this slight
difference is that they did not fix the pelvis during PSLR test and
that they did not perform a familiarization session and warm-up
prior to starting the test procedure.
