ETS: electromagnetic tracking system, ROM: range of motion, FAI: femoroacetabular impingement, ICC: intraclass correlation coefficient, CV: coefficient of variation, SEM: standard error of measurement, LOA: limits of agreement, Gonio: goniometer. Note that bias (retest lower than test) was significant only for adduction measured with the ETS (P < 0.01). |
