Patients aged 18-70 years were eligible for inclusion. The ECM group performed movements of the ankle five times a day from week 3 to week 8 after rupture. The control group was immobilised for 8 weeks. The primary outcome was the Achilles tendon Total Rupture Score (ATRS) evaluated at 1-year postinjury. The secondary outcomes were heel-rise work test (HRW), Achilles tendon elongation and rate of rerupture. Analysis was conducted as intention-to-treat using inverse probability weighting.FINDINGS/RESULTS: 189 patients were assessed for eligibility and 130 were included from February 2014 to December 2016. There were 64 patients in the ECM group and 58 in the immobilisation group. There were no statistically significant differences (p>0.3) between the ECM and the immobilisation groups at 1 year: mean (SD) ATRS was 74 (18) and 75 (18), respectively.
