Progressive Resistance Training for Adults With External Snapping Hip

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.
