All outcomes were assessed at three time points (baseline from 2008 to 2009, 2010 and 2012) and analysed with mixed effects regression.Results 400 patients completed all assessments. In all groups, physical function and pain severity improved over time. MBI improvement per month as compared with control was greater in the late rehabilitation (b=1.69, 95% CI 1.20 to 2.19) than the early rehabilitation group (b=0.96, 95% CI 0.68 to 1.24). This rehabilitation effect was however marginally decreasing over time. Superior improvement as compared with control with regard to pain was only found in the early rehabilitation group (b=−0.05, 95% CI −0.09 to −0.02). PTSD symptoms decreased over time, but the observed differences could not be specifically linked to the rehabilitation intervention.Conclusion Physical rehabilitation of earthquake survivors appears to be effective in improving physical function and, if delivered early, pain. Effects on mental health are less clear and need further examination using more consistent and frequent assessments of relevant outcomes and determinants.All data relevant to the study are included in the article or uploaded as online supplemental information.
