Table 1 Test-retest reproducibility (ICC) of four consecutive trials of force plate variables in four different postural control tests.

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

  Intraclass Correlation Coefficients
  Maximal Range Mean Stdev.
CoP deviation distance     
Test 1 0.22 0.22 0.38 0.34
Test 2 0.38 0.38 0.67 0.57
Test 3 0.36 0.36 0.62 0.55
Test 4 0.35 0.35 0.72 0.54
CoP deviation velocity     
Test 1 0.11 0.11 0.43 0.34
Test 2 0.30 0.30 0.72 0.52
Test 3 0.36 0.36 0.55 0.43
Test 4 0.29 0.29 0.73 0.56
  1. For each test the ICC of the maximal, range, mean and standard deviation of the CoP deviation distance or velocity are calculated.
