| KF CON 60 deg/s | 0.62 (0.28-0.82) | 3.5 | 13.1 | 9.8 | 36,5 |
| KE CON 180 deg/s | 0.68 (0.30-0.86) | 4.5 | 12.4 | 12.6 | 34.4 |
| KF CON 180 deg/s | 0.49 (0.03-0.77) | 3.1 | 13.9 | 8.5 | 38.5 |
| KE ECC 60 deg/s | 0.70 (0.40-0.86) | 11.5 | 18.0 | 31.8 | 49.7 |
| KF ECC 60 deg/s | 0.60 (0.22-0.81) | 9.8 | 21.5 | 27.3 | 59.6 |
ICC2,1, intraclass correlation coefficient; MD, minimum difference to be considered clinically important at a 95% CI; MD%, relative minimum difference at a 95% CI; SEM, standard error of measurement; SEM%, relative standard error of measurement.
