Table 2 Intra- and inter-rater reliability of maximal isometric knee extensor strength in each trial

From: Reliability and validity of knee extensor strength measurements using a portable dynamometer anchoring system in a supine position

  ICC Mean (95% CI) SEM (%) Mean (SD) MDC (%) Mean (SD)
Intra-rater 0.98 (0.96–0.98) 21.8 (4.5) 60.4 (12.3)
Inter-rater 0.98 (0.96–0.99) 22.2 (4.5) 61.6 (12.4)
  1. ICC: intraclass correlation coefficient, CI: confidence interval, SEM: standard error of measurement, MDC: minimal detectable change
