First-line Treatment for Femoroacetabular Impingement Syndrome

A 6 months exercise intervention of training 2 times a week. Patients will be instructed by a physiotherapist during the first session, in order to be able to perform the exercises at home or in a local gymnasium based on personal preference. Subsequently, there are supervised sessions once every second week (12 sessions in total). The intervention will consist of 6 exercises. 4 targeting planes of hip movement (i.e., flexion, extension, abduction and adduction), a general lower extremity- and a trunk exercise. Progression is made when an exercise is performed with the designated number of sets and repetitions, with good performance quality and tolerable pain. Progression is provided by 3 levels of difficulty and secondly by the number of repetitions or where possible by increasing the external load. In addition, patient information and education is identical to what is delivered in the usual care group.

Usual care varies slightly across regions in Denmark and between Denmark and Australia. The consensus is that the patient should be advised to remain physically active and reduce symptom provoking activities. Therefore, patients will receive a referral for physiotherapy and supplementary a minimal educational intervention is provided as usual care. Patients allocated to the usual care group will receive written information on self-management of hip symptoms including advice about staying physically active in accordance with the World Health Organization guidelines on physical activity and sedentary behavior. Moreover, self-management of hip symptoms will include advice to reduce symptoms by focusing on symptom-lowering activities and sports. The content of the information provided as usual care will be identical to the information provided to the patients in the intervention group. Patients in the usual care group can continue to seek any additional treatment they would like.
