Progressive Resistance Training for Adults With External Snapping Hip

Overview

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.

This trial is an international multicentre randomised controlled assessor-blinded crossover trial, following the CONSORT guidelines. The intervention is a 12-week progressive resistance training programme, and the trial is designed with three follow-up time points. After the baseline test, the patients will be randomised in a 1:1 ratio to either the intervention or the control group using the Research Electronic Data Capture (REDCap) source hosted at Aarhus University. For both groups, the first test will be the baseline test, conducted before the randomisation. The second test will be conducted 6 weeks after randomisation, the third test will be conducted 12 weeks after randomisation and the fourth and last test will be conducted 24 weeks after randomisation. The primary outcome will be the change from baseline to the third follow-up, and the trial will be powered based on this period. The lasting effect of the intervention will be evaluated from baseline to the fourth follow-up test for the intervention group.
