Table 5 Test-retest intraclass correlation coefficients from the mean angle velocities of pelvis movement in three directions of four consecutive trials in four different postural control tests.

From: Reproducibility of postural control measurement during unstable sitting in low back pain patients

Test 2 0.44 0.41 0.60
Test 3 0.10 0.11 0.06
