Abstract

OBJECTIVE
Lumbopelvic-hip complex (LPHC) stability is related to altered movement patterns that are present in individuals with PFP. Current studies measuring LPHC function in PFP primarily assess endurance and not stability. A test of isolated LPHC stability, the Seated Trunk Control Test (STCT) was recently developed and test-retest reliability for the STCT has been shown to be excellent in a healthy population. To improve the clinical usefulness of the STCT, we aimed to establish test-retest reliability for individuals with PFP. We hypothesized the STCT would show good-to-excellent reliability. We also compared STCT performance between healthy individuals and those with PFP. We hypothesized those with PFP would have lower TTE and greater NE.

MAIN OUTCOME MEASURES
Performance was measured as time to first error (TTE) and number of errors (NE) averaged between test trials. Intraclass correlation coefficients (ICC) with 95% confidence intervals (CI) assessed test-retest reliability utilizing a two-way mixed-effects model with single rater (ICC[3,1]). The Mann-Whitney U Test compared performance measures between groups, p < 0.05.
