Conditions
Summary
External snapping hip is characterised by an audible and painful snap during hip movement among physical active people around 15-40 years old. Progressive resistance training has been suggested as a new potential treatment path in treating patients with external snapping hip. The investigators conducted a feasibility study and found that patients reported less pain and improved their physical function, quality of life and muscle strength after 12 weeks of progressive resistance training. The overall aim of the project is to compare hip pain in patients with external snapping hip treated with progressive resistance training to a wait-and-see approach, in a randomised controlled trial. This study has the potential to establish a new and specific treatment option for patients with external snapping hip, to be used nationally and internationally.

Interventions
The progressive resistance program consist of a five-minute aerobic warm-up on either an ergometer bike, treadmill or rowing machine followed by six resistance training exercises: landmine twist, walking lunges, leg press, hip abduction, hip adduction and hip flexion. All training sessions (three per week) will be supervised for the first two weeks. After that, there will be one weekly supervised training session and two self-directed sessions. The subjects will be scheduled for 36 training sessions over 12 weeks, of which 16 will be supervised. Each training session is designed based on the findings from the feasibility study and is expected to last approximately one hour. If a subject cannot perform all scheduled sessions in a week, additional sessions will be planned for the following week to obtain the 16 supervised sessions.
