Objectives: To investigate feasibility and change in patient-reported symptoms of a home-based exercise intervention in patients with acetabular retroversion and excessive anterior pelvic tilt, in comparison with a prior control period. Design: Following baseline examinations, an 8-week control period was followed by an 8-week home-based exercise period. Subsequently, the patients were encouraged to continue with the exercise program for additional 16 weeks. Outcomes: Good feasibility was defined as; a ´dropout´ rate ≤10%, ´adherence´ to the exercise program as ≥75% completion (18 out of 24 sessions), the ratio of training sessions increasing pre to post ´exercise-related pain´ (NRS >4) should not increase, no serious ´exercise-related adverse events´, and usage of ´hip-related analgesics´ should not increase. Parameters regarding feasibility and general comments on the exercise program were recorded in the self-reporting training diary. Primary endpoint was HAGOS-PAIN subscale after the 8-week exercise period. Secondary endpoints were the remaining five HAGOS-subscales, EQ-5D-3L, and change in pelvic tilt (sagittal inclination in degrees) measured with low-dose radiation EOS® scanning in standardized standing position. One data set contains raw anonymous data for the complete exercise intervention at four time-points: T1) baseline, T2) start-up of exercise intervention 8 weeks from baseline, T3 end of exercise intervention after 8 weeks (primary endpoint), and T4 follow-up after 16-weeks. The second data set contains data from the training diaries. ClinicalTrials.gov: NCT03578562
