*Change is calculated by subtracting the pretest value from the post-test value.
†The adjusted treatment effect from least squares means is calculated by subtracting the MoveTrain minus Standard at post-test and assesses the between-group difference in post-test values after adjusting for pretest.
‡Unless otherwise indicated, p value by analysis of covariance using a generalised linear model.
§Patient-reported outcome measures with 100=no disability.
¶Patient Specific Functional Scale (PSFS) assesses the level of difficulty performing up to five activities due to hip pain or symptoms. 0=unable to perform activity; 10=able to perform activity at preinjury level.
**PROMIS T-scores for the measures included in this study range from 20 to 80 and have a mean score of 50 and SD of 10, using the US general population as the reference. A higher score represents more of the concept being measured. Minimally important differences (MIDs) have not been established for those with HRGP.

††P value by non-parametric analysis of covariance.
‡‡Pain rated by patients using a verbal numerical pain rating scale. 0=no pain; 10=worst pain imaginable.
§§P value by analysis of covariance using multinomial generalised estimating equations with a cumulative logit.
