Test-retest reliability of knee kinesthesia in healthy adults

Table 1 Test-retest reliability in the kinesthetic variables, in 24 healthy subjects.

Kinesthetic variables	Test session 1 Mean (SD)	Test session 2 Mean (SD)	Mean difference (SDdiff), 95% CI	ICC_2,1 (95% CI)	95% LOA_ratio
TE20	0.98 (0.37)	1.03 (0.51)	0.05 (0.35), -0.10 – 0.19	0.70 (0.42 – 0.86)	0.57 – 1.78
TE40	1.20 (0.52)	1.26 (0.75)	-0.06 (0.84), -0.41 – 0.30	0.16 (-0.27 – 0.53)	0.31 – 3.09
TF20	1.55 (0.66)	1.29 (0.70)	-0.26 (0.55), -0.49 – -0.03	0.63 (0.31 – 0.83)	0.42 – 1.57
TF40	0.79 (0.28)	0.81 (0.34)	0.02 (0.28), -0.10 – 0.14	0.59 (0.25 – 0.80)	0.51 – 2.01

Mean (SD) for test sessions 1 and 2, mean difference (SD_diff), 95% confidence interval (test 2 minus test 1), intraclass correlation coefficient (ICC_2,1) (95% confidence interval), and 95% limits of agreement (LOA) of back-transformation (antilog) of the LOA on a log scale (LOA_ratio) in the kinesthetic variables towards extension (TE) and flexion (TF) from the starting positions 20° and 40° (TE20, TE40, TF20, TF40).
